Discussion
A significant rebound in temperatures will take place today throughout the Mid-Atlantic region and the milder conditions will continue at the beginning of the weekend. A cold front, however, will pass through the region later tomorrow and colder air returns for Saturday night and Sunday. This injection of fresh Arctic air will be anchored by strong high pressure that will be edging into southeastern Canada later Sunday and Monday – a perfect location to sustain cold air in the Mid-Atlantic region and a crucial player in this upcoming threat for snow.
At the same time, low pressure will organize in the Southeast US and it will begin to head northeastward towards the Mid-Atlantic region with plenty of moisture and supported by a strong upper level trough. There are still plenty of details to work out in terms of how much moisture can penetrate this far north and east right into the heart of the Arctic high pressure system, but there is already enough evidence to suggest that accumulating snow, possibly on the significant side, could develop in the I-95 corridor from DC-to-Philly-to-NYC late Sunday or Sunday night and continue into Monday.
