Behind the Alberta Clipper we have quiet conditions. Winds have subsided and temperatures are rather cool. High pressure centered up over the Adirondacks is going to drop south and east. Southwest winds all cause temperatures to climb today and tomorrow.

We have an upper-level low exiting the southern Plains headed for the Ohio Valley. Looking at the satellite image we can see a lot of precipitation and convection (thunderstorms) ahead of the low pressure. The setup is such that this will be weakening a little before it approaches our region. Precipitation will move into southwest Pennsylvania, tonight, then this will move across the rest of the region during the overnight into Friday. With the warm temperatures this will be primarily a rain maker for much of Pennsylvania Middle Atlantic, Southeast New York State, into Connecticut, Rhode Island into southeast Massachusetts.  These areas look to see a general ¼ to ¾ of an inch with locally spots seeing 1 to 1.25 inches. Those with the best chance for mixed precipitation across the Twin Tiers of Pennsylvania and New York State into Massachusetts into southeast Maine. There could be just enough cold air in parts of the Poconos, Catskills, Lehigh Valley, across southern Hudson Valley into the Hudson highlands and parts of the Helderbergs to see some ice. Ice could add up to around a 1/10 of an inch. These areas could see a dusting to an inch of snow. North of I-90 in New York State as well as Vermont, New Hampshire into parts of Maine, it looks to stay primarily snow, a general 1-3 inches of snow is possible, along with a chance for some mixing. Parts of the Tug Hill, Adirondacks, Greens into the northern Berkshires could see 3-6 inches of snow with some higher amounts possible. Cold air will come in behind the storm, allowing for cold for Friday into Saturday as high pressure sets up.  We won’t be able to hold on to the high for long, as another area of low pressure approaches on Sunday, bringing a chance for snow/mix/rain. The active pattern along with up and down temperatures will be with us for next week.
