Monday Discussion : Frost Advisories & Freeze Warnings

by
* Frost Advisories and Freeze Warning in Effect for Portions of the Hudson Valley *
The National Weather Service in Upton Long Island (NYC Office) has issued Frost Advisories for Putnam, Rockland and Westchester Counties… along with a Freeze Warning for Orange County. The remaining counties in the Hudson Valley are covered by either the Albany or Binghamton Offices, and no advisories have been issued yet. It stands to reason however, that if advisories are in effect for our southernmost counties, that similar (or colder) conditions can be expected further north across the northern HV. Please plan for a hard frost, and possible hard freeze tonight.
**Orange County**
Freeze Warning issued April 22 at 3:55AM EDT until April 23 at 8:00AM EDT by NWS Upton NY
* WHAT…Sub-freezing temperatures as low as 30 expected.
* WHERE…Orange County.
* WHEN…From midnight tonight to 8 AM EDT Tuesday.
* IMPACTS…Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing.
Instructions: Take steps now to protect tender plants from the cold.
** Rockland, Westchester & Putnam Counties**

* WHAT…Temperatures falling into the mid 30s will result in frost formation.
* WHERE…Portions of southern Connecticut, northeast New Jersey, and southeast New York.
* WHEN…From midnight tonight to 8 AM EDT Tuesday.

Thursday Weather Discussion : Raw and Chilly

by
Low clouds and drizzle associated with a stalled frontal boundary have parked themselves over the Hudson Valley and eastern NY.
The radar doesn’t tell the story, because the low clouds and drizzle don’t really register on radar… but a persistent mist along with a few steadier rain showers will linger throughout the day on Thursday. The low level moisture will keep temperatures pinned in the 40s across the valley, roughly 15 to 20 degrees below average for this time of year. Not the nicest of days by mid April standards.
 
These conditions will be with us into Friday as well, with conditions improving a bit Friday morning. A few breaks in the clouds are possible, and temperatures should climb into the 50s. But a new approaching frontal boundary will bring a chance of more widespread, heavier rain showers around mid day to early afternoon on Friday. Not a washout, but you’ll have to factor the shower threat into your afternoon plans.
 
Make sure you have the heavy winter coat handy for today. The chill in the air will remind you of late February or early March. Have a great afternoon!

Wednesday Weather Discussion – Early Afternoon Showers

by
After 2 completely gorgeous days in the Hudson Valley, clouds and scattered showers will return on Wednesday along with an approaching frontal boundary. Early morning sunshine likely fades behind increasing clouds by mid to late morning. That sets the stage for scattered showers approaching from the west between noon and 4pm. The scattered showers appear light for the most part, but a few localized heavier showers can’t be ruled out.
The clouds and showers will also help keep temperatures down from where they were on recent days. Temps may climb into the upper 50s and low 60s around the region by mid day on Wednesday… but with the arrival of the rain showers, temperatures are likely to fall into the low to mid 50s during the afternoon on Wednesday.
The instability will be with us through Wednesday night, and on into Thursday. Low clouds, scattered showers and areas of drizzle will linger through Thursday… keeping temperatures quite raw and chilly for this time of year. Expect temperatures to spend much of the time in the 40s Wednesday night and Thursday.
Have a great Wednesday, Hudson Valley!

Sunday Discussion : Potential Late PM Storms?

by

A chilly and rather raw Saturday will transition to a mildly warm Sunday afternoon across the Hudson Valley.  The downside is that the warmer temperatures may come with the threat of strong to severe late day T-Storms.

Sunshine will mix with clouds early on Sunday… but clouds will advance again by late morning.  Late morning through early afternoon are likely to be mostly cloudy with a few scattered showers possible.  The key to the forecast is what happens after that.  Much of the guidance suggests that the clouds give way to increasing sunshine between 2pm and 4pm on Sunday… which would give us several hours of sunshine.  That sunshine would work with strong SW winds to warm temperatures quickly from the low to mid 50s around lunch time… to the upper 60s and low 70s by late afternoon.  If that happens… our radar could look very unsettled as sunset approaches…

Some guidance is suggesting a severe squall line sets up and takes aim on the Hudson Valley between 5pm and 10pm (peak risk around 7pm to 8pm).  If the atmosphere destabilizes due to the afternoon sunshine… T-storms will likely develop and spread across our area.  Damaging wind gusts are the biggest threat… with a 30% chance in the Enhanced area… a 15% to 30% chance of occurrence is likely for the rest of the region.

We’ll have to watch as we go through the day, and see if the skies remain mostly cloudy… or if the skies clear early in the afternoon.  If the clouds hold on longer than expected, the atmosphere may stabilize and cause the squall line to be weaker than projected.  Check back Sunday afternoon for updates on the situation.

Thursday Discussion: Spring Preview Continues…

by


Another beautiful day already underway as we approach mid day. Temps in the low to mid 60s across the region, with abundant sunshine and blue skies… will continue to climb this afternoon and approach 70° across some parts of the Hudson Valley. This afternoon will feel more like early May than mid March.

Clouds will advance on the region tonight, and give us a more unsettled end to the work week. Clouds and a few scattered showers are likely before sunrise on Friday. The scattered showers are possible thru the morning, and will leave us with a mainly cloudy sky for our Friday afternoon, along with highs in the mid to upper 50s (which is still about 10° above average for mid March).

Looking to the weekend, things appear a bit unsettled. Saturday looks mostly cloudy, but Saturday night into Sunday could see some scattered showers, but it doesn’t look like a complete washout. Highs both days are expected to be in the upper 50s to near 60°.

Enjoy the gorgeous weather!!

Beautiful Wednesday Weather

by
Tuesday was beautiful, but Wednesday looks even better!
Sunshine mixing with some fair weather clouds and a warm SW wind. Afternoon highs across the valley are expected to reach into the mid 60s on Wednesday, which is about 20° above average. We’ll see similar conditions on Thursday, with a few more clouds than what we’ll see on Wednesday. Afternoon highs however, will be very similar to Wednesday… reaching into the mid and possibly upper 60s on Thursday as well.
 
As we approach Friday, a frontal boundary will slowly approach the Hudson Valley from the north, and that could spread clouds and possibly some scattered showers by Friday morning. The afternoon on Friday doesn’t look like a total washout, but we’ll have to monitor the details for Friday closely. The weekend looks mostly cloudy and a bit unsettled… with a few scattered showers possible through the weekend… with afternoon highs in the mid to upper 50s through the weekend.
 
Some colder air likely returns next week, but the details remain a bit fuzzy at this time, so we’ll have more on that when the details are more clear. For now, we hope you’re able to have a wonderful Wednesday with some superb Spring-like weather!
