After a snowy Monday… Tuesday has followed with a cold, raw, rainy day. A warm front is approaching the region, and out ahead of it… was a good batch of rain. A soaking rain fell for a few hours during the middle of the day on Tuesday, with temperatures pinned in the 30s. That made for quite a raw day in the Hudson Valley.
As we move through the night, we’ll see scattered rain showers and areas of drizzle move into the Hudson Valley. Winds will be rather calm, so expect areas of patchy dense fog to also develop. Temperatures will hold in the 30s for a while, before a southerly wind begins to increase overnight. That southerly wind will usher warmer air up into the region… and temps will quickly rise from the 30s, into the 50s and even low 60s by early morning on Wednesday.
So those strong southerly breezes will warm things up rather nicely out ahead of the cold front. That cold front arrives mid day, and it could pack a punch as it moves through…
A line of showers and thunderstorms will likely develop along the front as it moves east. This could lead to a few locally heavy downpours, strong (potentially damaging) wind gusts, and even a few rumbles of thunder. The timing on this looks to be an hour or two on either side of 12pm… so be alert to the potential.
The winds will continue to be very gusty both before and after the passage of the cold front. So even while the temperatures are tumbling during the afternoon… back into the 50s and 40s… it will be very windy at times…
The winds could gust into the 40s… possibly near 50mph in one or two locations of the Hudson Valley. But the strongest wind gusts appear likely to remain up the Catskills, where gusts could approach 60mph in spots. As a result, we are concerned about the potential for some down trees and power lines Wednesday afternoon… and possibly some power outages. We’re hopeful that the winds won’t really reach their maximum potential… but we’ll monitor the situation as it gets closer.
Some more wild weather on the way the next 24 hours. We’ll walk with you the whole way… Have a nice evening!
Welcome to the month of April… but there are no signs of Spring to be found anywhere…
– 2am to 5am: Wet snow develops from west to east
– 9am to 12pm: Wet snow tapers off from west to east
– Northern Hudson Valley (Zone 1, 2, N3, N4,): Coating to 3 inches
– Mid Hudson Valley (Zone S3, S4, 5, 6 & 7): 2 to 5 inches
– Lower Hudson Valley (Zone 8 & 9): 3 to 6 inches
The storm is on the doorstep of the Hudson Valley, and everything appears to be going according to plan…
This radar image is from 1:30am, and you can see that there is a wide swath of snow that runs from the NY/PA border… all the way back to Lake Erie. This snow will push eastward… and without regard for the calendar saying it is April… we will see the Hudson Valley turn white once more on Monday.
The snow will really come down Monday morning across the Hudson Valley… at a rate near 1″ per hour in spots. Look at this radar simulation from our very best Hi-Resolution computer guidance.
Our first work week of April will start off with a THUMP of snow across the Hudson Valley. Looking at this simulation, it’s hard to imagine that the snow does not begin to accumulate on roadways. In the month of April, snow rarely accumulates on roads… but at night, if it snows heavily, it could happen. Make sure you check the roads in your area as you begin your Monday commute, as icy spots can’t be ruled out. The good news, is that once the sun rises on Monday… the roads will quickly improve. The sun’s rays will warm the pavements through the snow, and melt any snow quickly during the day.
Our latest and best guidance suggests that this April snow will really impress. As a result, we slightly bumped the accumulation expectations across the region. Because as this snow map highlights, it might be possible that someone sees 6 inches of snow from this event (purple on this map)
Could someone in Rockland, Putnam or Westchester county see 6 or 7 inches of snow? It’s not impossible. So on the average… a widespread 2 to 5 inches of snow seems likely… with our northernmost areas possibly seeing a bit less than that, and our southernmost areas could possibly see 6 inches in a few spots.
The snow should taper off from west to east between 9am and 11am… but a few locations near the NY/CT border may see it hold on until as late as 12pm. We’ll have updates on the Facebook page (and possibly on here as well), as the storm unfolds early Monday.
Due to the lateness of the season, and the fact that today is indeed April 1st… we’ll try to avoid the “April Fools” jokes with our discussion of a very REAL snow threat for Sunday night. It’s not a major event, and most (if not all) of what falls will struggle to accumulate on paved surfaces. But we are talking about the legitimate potential for April snow. So here are the basics:
– 2am to 6am: Wet snow develops from west to east
– 8am to 12pm: Wet snow tapers off from west to east
– Northern half of HV (Zone 1, 2, 3, 4, 5 & 6): Coating to 3 inches
– Southern half of HV (Zone 7, 8 & 9): 2 to 5 inches
Yes… it is April Fool’s Day… but this is not a joke, though many of you will surely wish it was. No, we do indeed have an area of low pressure pushing eastward today, through the Ohio Valley. It will arrive in the Hudson Valley after midnight, and spread a swath of wet snow into the region.
Temperatures are expected to be in the low to mid 30s when the precipitation arrives… so the wet snow could start as a brief period of rain… especially south of I-84. But any mix should change over to plain wet snow rather quickly. The wet snow will fall moderately for a time from I-84 on south… and should be lighter as you go further north.
With the temperatures being warmer… and the sun angle being higher in the sky… the temperatures of roads are warmer, and most (if not all) of the snow will melt on contact with paved surfaces. So while snow flakes will likely be flying when the sun rises on Monday… the roads in most areas will be just wet… not white. Even so… be sure to assess the conditions where you are locally, colder spots and higher elevations may see some roadways become snow covered… especially where the snow falls heavy for a time.
But this is a very fast moving system… and by 8am, you can see that the back edge of the snow is already trying to advance into the Hudson Valley…
The snow should begin tapering off from west to east, anytime after 8am. Most of the region should dry out by 10am… but a few snow flakes could linger on toward noon… especially in the southern HV. By the time it’s all over… a slushy couple inches could have fallen across the region.
Areas north of I-84 will likely see a coating to 3 inches… with the locations closest to I-84 getting the highest amounts, and the areas furthest north in the Catskills seeing the lowest amounts (probably just a coating). Areas from I-84 on south could see 2 to 4 inches of snow on average… with a few locations (mainly higher elevations) possibly seeing up to 5 inches of wet snow.
This is a fast moving system, and it only snows for about 6 hours in any location. So there just isn’t enough time & snow to get much more than 2 to 3 or 4 inches in any location. But the snow could come down pretty heavy for a period of time, and it should coat all unpaved surfaces pretty well. The biggest travel headache is probably the reduced visibility that results from moderate to heavily falling snow. But we’ll also have to watch for the potential of some snow covered roadways (especially in higher elevations). While most of us likely only see wet roads… it IS April after all… we should never dismiss the potential for icy roads entirely.
The sun comes out by mid day on Monday, and temps will surge into the mid and upper 40s… melting almost all the snow that falls. So you snow haters can at least have that to hold on to. The joke is on us this April’s Fool’s Day… as we have a high probability of accumulating snowfall late tonight. The good news, is that it isn’t a lot… it won’t snow for very long… and whatever falls, likely melts before sunset on Monday. Have a great Sunday, everyone!
Spring has been in the Hudson Valley for about 10 days… but only on the calendar. The weather has refused to follow suit… holding about 2 to 4 degrees below average. As we turn the calendar into the month of April, we don’t expect any changes in the pattern. In fact, we’re watching a chance for a snowy April Fool’s Day joke, that many people won’t find funny.
Looking at the weekend, Saturday looks quite nice to be honest.
We’ll see a good deal of sunshine on Saturday, and temperatures near where we’d expect them to be for this time of year. It won’t be a beautiful day by most standards… but it will likely feel pretty good to get sunshine and seasonable temperatures across the region. Anyone with outdoor plans, will be rather happy with what the weather will offer.
Looking to Saturday night into Sunday… a weak frontal boundary will move into the region. That will bring clouds into the area once again, along with the threat of a few spot rain showers. The spotty showers will taper off on Sunday morning, and leave us with a chilly breeze for much of Sunday, under a mix of clouds and sunshine.
Not a terrible early spring weekend… with Saturday looking better than Sunday. But as we look toward Sunday night into Monday, we’ll see that winter won’t go quietly into the night.
Wave of Spring Wet Snow Possible…
A weak wave of low pressure will move through the Ohio Valley Sunday night and reach the east coast by Monday morning. Depending on the exact track of the low pressure… we could have a WHITE start to the work week.
We’ve been watching this system for a few days, and the bulk of the snow was focused south of the Hudson Valley. But as is often the case, these systems begin to trend further north as the event gets closer… and now we are seeing a scenario where at least part of the Hudson Valley sees wet snow for the Monday morning commute.
Looking above at the futurecast radar for 8am Monday morning, a band of snow is possible anywhere from Washington DC, up through the Hudson Valley. This latest scenario has the snow focused in the southern half of the Hudson Valley, mostly from I-84 on south. This is quite a sizable shift north in the projected track in recent days… so we’ll have to see if this trend continues, or if the potential track shifts further south once again.
Our concern, is that the track could trend a bit further north than what we’re seeing here. The current projection would generate a slushy coating to an inch or two across the region from I-84 on south. But if the storm tracks another 25 to 50 miles north… it would pull a swath of 2 to 4 inches of wet snow into the Hudson Valley, just in time for the Monday morning commute. So we need to keep focused on this event.
As you know, we’ll be watching it closely… and share any updates with you as they develop. But for sure… winter just won’t go down without a fight. And suffice it to say, this won’t be the last time we are talking about snow threats… as the first HALF of April continues to look cold and unsettled.
A quiet but cold start to our weekend. Partly to mostly sunny skies will be the story of the day, but our northerly flow will keep it quite cold for this time of year. Highs will struggle into the low and mid 40s. So make sure you grab your winter gear, as our cold pattern looks to last into the start of next week.
We’ll have a weak disturbance slide southward from New England overnight and spread some light snow showers in parts of the area before sunrise on Sunday. We are not expecting widespread problems, but something to watch out for in the early morning hours.
In the wake of our ‘almost snowstorm’, temperatures really warmed up on Thursday… into the mid and upper 40s… and melted almost everything in just the matter of a few hours.
Today, late winter’s chill will try and hold on for dear life, as we have high clouds filtering our sunshine. Temps will be below normal again today, as highs climb only into the low and mid 40s today.
We are watching a northerly flow try to usher in some slightly cooler temps… as well as a few snow flurries and rain sprinkles. This could briefly dampen the situation across parts of the region, especially the northern HV and Catskills. But in general we look dry and chilly today.
There was some buzz about a Sunday storm in or comments the past few days. We aren’t sure where that started, but there is no storm threat. We could see a few snow or rain showers rotate out of New England, as an ocean storm influences our weather… but there is no storm on the horizon for the next several days.
This month has featured 4 nor’easters that have impacted the Hudson Valley in one way or another. Unfortunately or fortunately… depending on your perspective… the end result hasn’t really been representative of the time and effort that went into forecasting the storm. Case in point… our storm from Wednesday.
When we look at the final statistics… they’re not that impressive. But when you realize that if you headed about 50 miles south, the resulting impact was incredible for a nor’easter that hit in the 2nd half of March. You can see it on the map… the areas in Long Island that got 12 to 18 inches of snow. There were multiple times during the forecasting period, where we thought that those 12 to 18 inch amounts could push all the way into the Hudson Valley… even right up until the last minute. Check out this NAM model projection, that was generated Tuesday night around 10pm… less than 12 hours before the storm was expected to begin…
Yes, this guidance suggested a MAJOR impact in the Hudson Valley, just hours before the storm was to begin. So while we were crunching data, and weighing our ideas on what the actual snowfall forecast should be… trying to shrug off information like this, was not so easy to do. So yes, the Hudson Valley only saw a minor event on average… with our viewers from the lower Hudson Valley (Rockland & Westchester counties) seeing a sizeable impact event, with around 6 to 8 inches in some spots.
When we weigh out the result… against what our forecast was… our forecast actually performed quite well. Most schools and many businesses closed early or didn’t open at all on Wednesday… despite the fact that the snow never came until after dark. So it caused much frustration and even some anger across the Hudson Valley, as claims of a ‘bust’ began to ring loud and true. But our forecast was never for a major impact in the Hudson Valley… and the widespread 2 to 6 inches that we projected over the Mid Hudson Valley actually came true.
So the storm certainly wasn’t what some people expected… probably because the news networks were in a frenzy, talking about the storm that did drop a foot or more on the metropolitan area. But locally… the storm was yet another ‘near miss’, that had light to moderate impacts on the Hudson Valley. The clock on winter is ticking… we’ll see how much time is left on the clock, before the final buzzer on the winter season goes off.
For roughly 10 hours… moderate to heavy snow fell from the skies across the Hudson Valley today… only to evaporate in the dry air before reaching the ground. However between 8pm and 11pm… the snow FINALLY began reaching the ground across the Hudson Valley.
You can see on radar that we have light… to locally moderate… snow across the Hudson Valley. The snow is rotating counter clockwise around the coastal low pressure system that has been spinning all day off the east coast. We have reports of 1 to 3 inches of snow across the Mid Hudson Valley, and higher amounts as we push southward into Putnam, Rockland and Westchester counties.
THE NEXT FEW HOURS…
Expect the light to moderate snow to continue through 3 or 4am across much of the region, before tapering off before sunrise. When all is said and done, accumulations should be…
– Catskills and Northern Hudson Valley: coating to 1/2 inch
– Mid Hudson Valley (where 2″ to 6″ was forecast): 1 to 4 inches
– Lower Hudson Valley (where 6″ to 12″ was forecast): 4 to 10 inches (locally 12″)
After being dry all day, roads are now snow covered and icy in many areas… so be alert that the Thursday AM commute may be a slick one. Winds will also continue to gust out of the NE at 15 to 30mph, so be sure to hold onto your hat when you’re outside.
This storm was advertised by HVW as a major uncertainty. We could have just as easily seen widespread 12 inch totals across the region from this storm, based on the data we were looking at leading up to the storm. Our coverage was thorough and highlighted the sharp cut off that was expected, the chance for a ‘rip off zone’ that ran straight over the middle of the Hudson Valley. There were so many factors with this storm, that we put out our forecast of 2 to 6 inches across the central HV, dand then spent the rest of our time showing you how that 2 to 6 could easily become a dusting to an inch… and how 2 to 6 could easily become 12″+. These complex storm systems require complex explanations & forecasts.
While the vast majority of HVW viewers understand and appreciate this… we’re trying to reach those who have been harshly critical of us today. We hope that as this storm wraps up over the next few hours, it becomes a bit more clear to some critics, just how complex this dynamic system was to forecast.
If you look at the radar… this storm looks like it’s really coming down across the Hudson Valley as we approach sunset. Unfortunately, that’s just not the case. Despite the moderate (dark blues & light greens) to even locally heavy (dark greens & yellows) snowfall returns coming in on radar… there is a patch of VERY dry air in the mid levels of the atmosphere. The result is that despite a very active radar… virtually no snow is reaching the ground north of Putnam and Rockland counties.
The magnitude of this dry air was no where near accounted for accurately. The question we were focused on, was how far north the snow band seen on radar would get. By all accounts, our forecast would have been on track if not for the unexpected strength of the dry air. But look at this newly modeled weather sounding…
Now this sounding has a lot of information on here that likely means nothing to most people, but the sounding is a useful tool for us to take a snapshot cross section of the atmosphere. The key take away are the red and green lines. The red line represents the air temperature from the top of the atmosphere, all the way down to the surface (1000mb on the left side of the graph). So it’s 36°F at this location. The dew point is 23° at this location, and so the air is quite dry. When dealing with a snow event, the dew point and the air temperature need to be fairly close… because we’d want to see humidity levels around 70% to 80% on average to get the snow to reach the ground.
But as dry as the air is at ground level… just go up into the atmosphere a bit, to around 850mb. Notice how the red and green lines go in opposite directions from each other. The further the lines are away from each other, the drier the air is, and the closer they are, the more humid the air. At 850mb (just below cloud level) the dew point and air temperature are over 20 degrees Celsius apart! The air is EXTREMELY DRY! Because if you notice, if you go up a little higher in the atmosphere, to 700mb… the red and blue lines are right on top of each other, roughly 100% humidity. The air is PLENTY moist enough to support the snow.
This is the entire problem… and it was not accounted for by any of the earlier computer guidance. The end result, is likely the following… if you haven’t seen snow yet, you’re likely not going to see any snow from this system.
That’s the truth of the matter, ladies and gentlemen. The air is just much too dry to erode that much dry air. Even with moderate precipitation falling into that dry air… it’s not moistening the air fast enough in most locations. So pretty much anywhere north of I-84, is likely to see no snow at all from this system, as a result of the dry air. Those areas weren’t going to see much anyway… but instead of 2 or 3… maybe 4 inches in places like Kingston, New Paltz, Poughkeepsie and Monticello… you’re likely going to see zero inches.
Now… in some parts of the Mid Hudson Valley, the snow will win out, and moisten up the atmosphere enough. There will be places where light to moderate snow falls tonight, near the I-84 corridor. The best chances will be for areas east of the Hudson River, but it’s really contingent upon banding of the snow. Where the heavier bands set up on radar, will determine where the best chances of snow falling are. It wouldn’t surprise us to see someone get a couple inches in parts of southern Dutchess county.
This map may be a little too pessimistic, but you get the general picture. All the accumulating snow is focused near and south of I-84… because the magnitude of the dry air is just so strong. So anyone near or south of I-84… expect snow to develop if it hasn’t already… and an inch or two is likely near the I-84 corridor. As you go further south, into zones 8 & 9 (Rockland, Putnam and Westchester), an additional 2 to 4… maybe 5 inches of snow could fall tonight. That would be enough to get those areas into the low end of the forecast range… but it is certainly a possibility there.
The dry air has completely evaporated this snowstorm for the Hudson Valley. There will be some snow tonight in the Mid Hudson Valley and points south, but exactly how much depends on the resilience of the dry air. Unfortunately, it’s extremely difficult, if not impossible, to tell just how long the dry air will hold ground. Most indicators are that it will give way to the moisture and snow will fall… but there is uncertainty for sure. We’ll have more updates as the night continues.
This storm is not pulling any punches. Not only was it a major challenge to decipher where the banding of snow would set up… we’re now trying to iron out if and when this dry air will ever ease it’s grip on the Hudson Valley.
The radar looks great for the southern half of the Hudson Valley at this hour… but the observations tell a completely different story. Everything north of the black line is evaporating before reaching the ground… because the air is so incredibly dry across the Hudson Valley. So areas like Newburgh, Middletown, Montgomery, Fishkill, even Poughkeepsie… it may look like the snow is falling or is about to fall… but it’s really just cloudy, breezy and cold.
The dry air was always a concern for the northern Hudson Valley and Catskills… where it’s safe to say there will be no snow from this system.
Basically… the areas where we originally highlighted as a coating to 2 inches…
those areas will officially see nothing. We were always skeptical of the snow pushing into those areas, and it’s all but been confirmed now, that the snow will never reach the Catskills or the northern Hudson Valley.
The areas where we originally had 2 to 6 inches forecasted…
there we have added another wildcard factor, in the form of very dry air. The snow band has pushed into parts of this area on radar… but the dry air is causing it to evaporate before reaching the ground. As the snow continues to fall into the atmosphere, it should moisten the air and begin reaching the ground at some point… but exactly when, is anyone’s guess. Our latest guidance suggests that as the storm rotates eastward tonight, it will swing bands of moderate snow northwestward… into the Hudson Valley. So periods of snow are certainly possible late this afternoon and tonight… but the strength of this dry air is the wildcard.
The areas where we had originally forecasted 6 to 12 inches
Those areas still stand to see a decent snowfall from this system. The snow has eroded much of the dry air in these areas, and you’re now looking at 8 to 12 hours of steady snowfall. As a result, as these bands of snow rotate in, snowfall rates could exceed 1 inch per hour at times. We think a general 4 to 8 inches is likely… with some areas possibly reaching 12 inches down by I-287. The extreme southern Hudson Valley could see someone come in with a foot of snow.
Bust of a Storm…
We spent 2 solid days trying to drive home the unpredictability with this storm system. We published our snowfall forecast, but really did not want to focus on the totals… because there were just too many variables at play. Figuring out the exact progression and cutoff of the northern edge of the snow, was always going to lead to areas getting “ripped off”… but the question was exactly where.
A lot of schools closed today… and the rest opted for early releases… and it’s very likely that not a single flake will have fallen by the end of the normal school day. “Wait and see” was a message we tried to convey, to minimize the number of cancelled and altered plans in areas where the weather remained cloudy and dry.
This storm got a LOT of air time from the news networks, because the NYC area stands to get clobbered by this system, along with the southern most portions of our viewing area. But the northern half of the viewing area was never expected to be majorly impacted by this storm… and we did our best to communicate that.
When dealing with such complex and complicated storm systems… it’s crucial to listen to the details of the forecast… especially when the forecasters are emphasizing the conflicting data and uncertain data that they’re seeing.
Still Some Surprises Yet to Come…
This storm isn’t over… not by a LONG shot. Now, for some parts of the area (Catskills & Northern HV), this was never your storm to begin with, so we’re not talking to you per say. However, in the mid and lower Hudson Valley… you need to keep watching this storm.
It may not have done what you expected so far today… honestly, it wasn’t expected to do all that much by this point regardless… but we need to watch as this system wraps up off shore this afternoon. The low pressure will sit and rotate off shore for the next 12 to 18 hours… and as it does, it’s expected that bands of snow will rotate in NW off the ocean.
So you see… there will be snow to contend with for many parts of the Hudson Valley later today and into tonight. So we’ll have more updates as the day progresses.
We mentioned on Tuesday in the evening live stream, that this storm reminded us of the blizzard a few years back that shut down the Hudson Valley. That storm also expected a sharp cut off across the mid-Hudson Valley, and we weren’t sure exactly where it would be. In that storm, Montgomery and Newburgh got 0.0″ of snow… but a half hour drive to your south… in Warwick, they saw 12″ of snow. When all is said and done, this storm will likely look a lot like that… we shall see.
– 6am – 10am: Snow develops from south to north
– 10am – 6pm: Snow could fall heavy at times in SE HV
– 6pm Wednesday – 12am Thursday: Snow tapers from west to east
– High uncertainty with forecast (Especially NW
– Exact track of Low Pressure will likely change at last minute
– Banding of snow could reach SE HV, more confidence in forecast there
– Dry air on NW side, could mean no snow at all in Catskills & N. HV
– Catskills & Northern HV (Zone 1 & 2, N3, N4) : Coating to 2 inches
– Majority of Hudson Valley (Zone S3, S4, 5, 6 & 7) : 2 to 6 inches
– Lower Hudson Valley (Zone 8 & 9) : 6 to 12 inches
No major changes to the preliminary forecast… mainly because we have not seen anything to increase or decrease our confidence levels. This forecast provides a good starting point for what to expect with this storm, however there will be some surprises as the storm begins to unfold early on Wednesday. Many of us will need to roll with the punches as we ‘now-cast’ on Wednesday morning.
Lets take a look at one of the most recent simulations for how this storm will unfold…
The snow pushes northward into central PA Tuesday night, and reaches the edge of the lower Hudson Valley by sunrise on Wednesday. The CRITICAL question, is ‘how far north does this snow shield advance?”
This simulation suggests that the snow makes it just about to I-84, before stalling out. Once the snow’s northward progress stalls… the snow shield begins to rotate and pivot around the low pressure off shore. So in this situation, we’d be looking at 4 to 6… maybe 8 inches of snow from I-84 on south, while there is literally NOTHING north of there.
The suggestion is that Long Island and NYC get absolutely CRUSHED… which is certainly possible. But over the Hudson Valley, notice the dramatic cut off. The suggestion is that Delaware, Sullivan, Ulster and Greene counties get nothing… not even a snowflake. But zone’s 8 & 9, would fall safely within the 6 to 12 inch range projected. So once again… the Hudson Valley is ground zero for the rip off zone.
Breaking Down the Forecast
So when you look at our forecast, the 6 to 12 inch range in zones 8 & 9 are the areas we feel best about. Odds are decent that as the storm pivots before moving east… that the deformation snow bands that could produce snowfall rates at 1 to 2 inches per hour, could impact Rockland, Putnam and Westchester counties. Those areas need to be prepared for a significant snow event… and it’s possible that those areas could even exceed the forecast range.
The Catskills and northern Hudson Valley (zones 1 & 2… as well as the northern half of zones 3 and 4), are likely to see little if any snow at all. We projected a coating to 2 inches… but that is really being optimistic, and assuming the scenario where this storm really hugs the coast. As you can see by the simulation above… odds are quite high, that the northern HV and Catskills will be cloudy and cold… with barely any snowflakes at all. We wouldn’t be surprised at all if most everyone in this region saw 0.0″.
The Mid Hudson Valley is the most complex part of the forecast hands down. To say we don’t feel good about this region would be a big understatement. We have 2 to 6 inches projected, because we have it as the dividing line between “snow and no snow”. As the expected northwestern edge of this storm, with a dramatically sharp cutoff expected… this area has BUST written all over it.
The further north you go, the more likely you are to see no snow at all. The further south and east you go, the better the chances you see accumulating snowfall. The question is… how much snow can you see in this area?
It’s a brutally tough call… and no matter how much data we crunch, we’re guessing at where the cutoff sets up. We are going to use our historical experience, which tells us that these upper level low pressure systems always tend to track further NW than expected. So with that logic, it wouldn’t surprise us if the accumulating snow reached back toward the base of the Catskills. But even then… are we talking about a dusting to an inch?… or 4 or 5 inches? Who can be sure.
We’re going to have to ‘now-cast’ this event, especially for this area. And as we get a better understanding of how dry the atmosphere is, what the position of the low pressure is, where the banding sets up… we should be able to begin honing in on snowfall totals in this area. Expect snow to interrupt your Wednesday plans anywhere from Monticello to Ellenville, to New Paltz, to Poughkeepsie. But it’s also entirely possible that the day is gray and dry…. it’s just too close to call with certainty.
Impacts (Wind, Power loss?)
In terms of impacts… the SE Hudson Valley (Rockland, Westchester and Putnam counties… as well as Eastern Orange to some extent) could see considerable impacts. NE winds will pick up and gust over 25mph at times. If we get into the deformation band, and snowfall rates are 1 to 2 inches per hour… that heavy, wet snow, will likely coat trees and power lines. Factor in that wind, and we could be talking about power outages once again, in areas that have already been hit hard this month.
Trying to look at the bright side… with the nor’easters so far this month, most of the weak tree branches should have already been taken out. So in terms of total power outages, lets hope the numbers are down, because the more susceptible trees and power lines have already been eliminated, and what remains are stronger trees and branches that can handle the extra weight and stress that results from the snow and wind. We can hope.
We have our hands full… there is no question. We’ll have updates and discussions all the way up to the event. As we begin to see things that concern us, we will pass the information along to you. If we feel that some areas will see substantially more or less snow… we’ll let you know. It’s a complex storm track, with an upper level low, and the dramatically sharp cutoff is right over the Hudson Valley. Buckle up for a bumpy ride, Hudson Valley!
