Discussion

The day dawns with the lowest temperatures of the season so far in the Mid-Atlantic region and, in many spots, it is near or at a record low for the date. After a very cold Tuesday, temperatures will moderate at mid-week as a “clipper” low pressure system pushes well to the north of here resulting in a stiff southwesterly flow of air on Wednesday that’ll bring in slightly milder air. Some precipitation is likely on Wednesday with this initial “clipper” system and - despite the warm up - it may still be cold enough in some areas for a mix of rain and snow at the onset. Another “clipper” system can bring a touch of snow to the area later Friday and then a third one can produce some snow in the Saturday-to-Sunday time frame. That last “clipper” system will usher in another bitter cold Arctic air mass for the late weekend and early part of next week…warmer weather is possible later next week.
