Discussion
A major blast of Arctic air will arrive here later today and it’ll be very cold from tonight through Monday in the I-95 corridor with temperatures having a hard time reaching the middle 30’s. In addition to this cold blast that is sweeping across the nation, there will be a couple of snow threats over the next several days. The first chance for snow in the I-95 corridor will come later Thursday night/early Friday from an initial wave of low pressure that will intensify near the east coast and then the second threat comes this weekend as another wave of low pressure will strengthen near east coast. Accumulations are likely from the intial system late Thursday night/early Friday on the order of a dusting to an inch or two and roads could get slippery. Both of these threats currently favor areas just to the south and east of the DC-Philly-to-NYC corridor for the highest accumulations; however, there is still time for a slight shift to the N and W which would make it quite interesting around here.
