Discussion
Arctic cold has gripped the Mid-Atlantic region and won’t loosen its control for awhile. Today will turn out to be the coldest day of the winter so far with a biting wind and temperatures struggling to pass the freezing mark for afternoon highs. The Arctic cold will stick around well into the upcoming weekend and attention will turn to the west as the next winter storm as it crosses the nation. That next storm system poses a threat for significant accumulating snow in the Mid-Atlantic region and it can be a long duration event with an impact here from Sunday morning all the way into Tuesday. Snow is likely to arrive here on Sunday morning and there can be 3-5 inches of accumulation by the end of the day at which time mixing of the snow is quite likely to take place. More snow or a wintry mix is possible on Monday and Tuesday as a (secondary) storm intensifies near or just off the Mid-Atlantic coastline.
