Discussion
Widespread record or near record cold this morning in much of the Mid-Atlantic region and Northeast US with, for example, lows of 20 degrees in Allentown, PA, 24 degrees at BWI and Dulles Airports (both records), and the upper teens in the Pine Barrens of New Jersey. After a very cold start to the day, there will be some modification in temperatures this afternoon, but that will not be the end of the cold weather. Even though it turns even milder on Thursday to go along with occasional showers and a possible thunderstorm or two, more Arctic air will arrive by Friday and the end of the week and weekend will be well below normal for this time of year. In fact, low temperatures on Sunday morning could be as cold as they were this morning across the Mid-Atlantic region. In addition to the late week and weekend cold, there will be lots of upper level energy hanging back in the cold air mass and we’ll have to watch for the possibility of some snow or snow shower activity on Saturday.
