A potent area of low pressure will track from the Tennessee Valley today, to the southern New England coast Thursday morning, and into the Gulf of Maine by Thursday evening. Snowfall will overspread the Capital Region and vicinity later this afternoon and evening, working steadily from southwest to northeast. Snow may become locally heavy at times during the evening and overnight hours. Snow may also mix with sleet and freezing rain from the Capital District and points south and west. Portions of the lower Hudson Valley and southwestern Connecticut may also see a change over to just plain rain for a time tomorrow morning.
Precipitation associated with the storm system should begin to taper off during the mid to late morning hours on Thursday. Weak high pressure will build in behind the system to round out the week before another storm approaches the region, from the south, in time for the weekend. At this point in time, it appears as if this storm may track too far to our south to be a major weather threat to the region, though we are continuing to closely monitor its evolution and progress.
As we head toward 2013, a chilly airmass will take hold of the region later this weekend and into early next week, as a strong high pressure, with Arctic origins, advances toward the northern tier of the Continental United States early next week.
…Below is the official forecast for the Capital Region and vicinity…
