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!
