Thursday will be one of the mildest days we’ve seen in quite some time, with winds out of the SW in the Hudson Valley. Morning temps in the 20s will climb into the mid 40s by afternoon, thawing out the region for at least one day. But a deepening coastal storm offshore will exit and pull down a reinforcing shot of arctic air on Friday. Temps will tumble Friday afternoon, and plummet Friday night. So that by Saturday morning in the Hudson Valley… this is what we can expect.
The morning will be quite harsh, with wind chills between 10 and 20 degrees below zero expected. Be sure to dress accordingly this weekend, as these conditions can quickly become dangerous if you’re not prepared. Highs on Saturday won’t reach 20°… which sets the stage for Sunday.
We continue to watch the setup for Sunday night into Monday. It’s a complicated setup, but a storm will drop out of the midwest on Sunday, and then swing up the coast Sunday night into Monday. With plenty of arctic air out ahead of the system, the stage is set for a potential significant winter storm. The keys are in the details.
Futurecast Map : Sunday PM through Monday AM
Just a quick look at the map shows a wide variety of wintry weather over the northeast. Current guidance suggests a storm that tracks well inland. So despite the frigid air mass out ahead of it, the storm pushes into central PA and NY, which floods warm air into the Hudson Valley late Sunday night, so that we would experience a wide spectrum of precipitation.
The details are very much in doubt at this point. The possible scenarios range from a couple inches of snow… changing to sleet and rain, to a scenario that is mostly snow which could drop up to a foot of snow. The signal for a significant east coast winter storm is there… the question is, what will this storm look like for us? Have a great Thursday!
