Wednesday was a major improvement in our weather… until the rain moved in. Poughkeepsie was 47° around 3pm, and temperatures were in the mid to upper 40s across the Hudson Valley (30s in the Catskills). But there was a shallow layer of very cold air in the mid levels of the atmosphere (roughly 2,000 to 3,000 feet up). When the rain began to fall… 2 things happened:
- The rainfall forced the colder air down to the surface… dropping temperatures nearly 10 degrees in just the matter of an hour or two (from the mid & upper 40s… to mid & upper 30s)
- That cold air froze the rain drops as they fell… and before the warmer air could melt them again… they fell to the ground as sleet. Yes… sleet!
Sleet (and even snow) mixed with the rainfall Wednesday afternoon, and threw many of us for a loop. While reports of slick spots (only 1 or 2 reports) were confined to the Catskills, just the fact that sleet was falling got the Facebook page stirring. Mother Nature is always full of surprises… thankfully this surprise was a minor one, and its only real impact were a couple glazed decks, and the sounds of ice pellets bouncing off metal.
Thursday… we can assure you… there will be no sleet. All layers of the atmosphere are safely above freezing, and we will see areas of dense fog to start the day. Expect some very foggy conditions for parts of the area during the Thursday morning commute. But that fog will begin to burn off as the day wears on, as showers become more numerous across the Hudson Valley.
The temperatures will rise well into the 50s across the Hudson Valley under mainly cloudy skies. A few scattered showers are possible from late morning… all the way through the afternoon. By sunset, the showers are likely widespread across the HV, and the steadiest rain is advancing toward us…
That line of showers could have a few rumbles of thunder along with it as it arrives. The chances are relatively low… but don’t be surprised if you hear a rumble or two as the steady rain arrives in the Hudson Valley. As the evening wears on… the steady rain sets in…
From there, it’s a fairly wet Thursday night. The rain isn’t particularly heavy… but could fall light to moderately for several hours. After midnight, we should see the rain become more “showery” and scattered in nature. We could also see some areas mix with wet snow as the rain tapers off… as cold air once again races into the Hudson Valley.
Friday is another transition day across the HV… as we go from very mild… to very cold. Temps on Friday at least… should still make their way into the mid and upper 40s… before the chill really sets in again for Saturday. Complete forecast details are up in the HVW 5 Day Forecast, so be sure to check there for more info.
Have a safe and happy Thursday… we’ll try to have updates as necessary on the rain situation.
