Arctic high pressure will continue to build across the Mid Atlantic region through tonight; it’ll begin shifting offshore during the day Thursday. While another cold front will move through later Friday, temperatures will moderate over the coming days.
Clear skies and light winds in the Eastern U.S. will produce nearly ideal radiational cooling conditions. As such, low temperatures will dip to well below normal readings tonight. The National Weather Service expects temperatures to be cold enough tomorrow morning to break record wake-up low temperatures again.
While conditions will moderate tomorrow, they’ll still be about 10 degrees below normal for this time of year across the Eastern U.S. While the cold is around, the snow isn’t; there doesn’t appear to be any organizing winter storm threat on the horizon anytime soon.
