A Winter Weather Advisory is in effect for the entire region on Sunday. Temperatures are tumbling into the 30s overnight Saturday, and by sunrise on Sunday, temperatures will be low to mid 30s. At the same time, moisture will climb into the region from the south. The result could be some icy spots with the onset of the rain.
– Rain develops between 4am and 8am, mixing with freezing rain in spots
– Localized icy conditions possible, in traditional colder valleys
– Scattered rain showers through the afternoon
– Wet snow mixing in from 5pm through midnight
– Slick conditions possible into Monday AM
Futurecast Radar: 7am Sunday – 7am Monday
Looking at the futurecast radar, the Hudson Valley sees rain in the region by sunrise on Sunday. There could be some sleet mixing in near sunrise, as the precipitation falls heavy for a time. But you’ll notice that the rain showers begin to be spotty in nature. So instead of a steady rain all afternoon… it appears likely to be cloudy with periods of light rain showers. Some spotty icy spots are possible… but based on the temperatures should be in the mid 30s for most locations…
If this model is accurate… and it’s usually the best data in this time frame… widespread freezing rain does not appear to be a problem. There definitely will be pockets of icy conditions, as you can see by the highlighted colder areas where temps could be below freezing. But a cold rain appears to be the primary concern. With that said… with a concern for freezing rain… you never want to let your guard down. Be prepared for some slick spots in the morning on Sunday.
But as the day progresses, the low pressure will develop off shore, and we’ll see colder air begin to return into the atmosphere… changing rain showers to wet snow from NW to SE near and after sunset. But once again, temperatures will be near to above freezing. So snowfall accumulation will be difficult, with a lot melting on contact…
Indications are that a slushy coating to an inch in spots should about do it. Now, if the cold air is a bit faster… and surface temperatures fall below freezing before the snow exits the area… an inch or two can’t be ruled out. But guidance is suggesting that accumulations are primarily in higher elevations (above 800ft). We’ll have to see how it unfolds.
