Discussion
The overall weather pattern from tonight through the middle of next week will be quite volatile with a wild swing in temperatures of about 45 degrees from today’s highs near 65 degrees to early Sunday morning lows near 20 degrees. This late week "January thaw" will result in heavy rain for the I-95 corridor and thunderstorms could even get mixed into the picture as well as some patchy fog. As Arctic cold arrives in the big cities tomorrow morning, the precipitation could mix with or change to ice and/or snow before ending. Then, after a couple of dry and quite cold days, accumulating snow may threaten the I-95 corridor from later Tuesday into Wednesday as a reinforcing Arctic blast arrives in the eastern US.
