Major cold/snowy blast on the way

The biggest weather story of the week in the Mid-Atlantic region is likely to be the bitter cold coming at mid-week because of its unusual nature for this time of year; however, there are also multiple waves of energy in the northern branch of the jet stream that can cause snow on numerous occasions during the upcoming five days or so. The first upper-level system to monitor is likely to generate some snow and/or rain shower activity in parts of the Mid-Atlantic region and there can be some snow squall activity as very cold air pours into the region later tomorrow into tomorrow night. After a very windy and cold day on Wednesday, a second wave of energy will drop southeast towards the Mid-Atlantic region on Thursday and it could generate some accumulating snow in a very cold air mass. Another snow threat will come late Friday as a couple of waves of upper-level energy try to consolidate near the Mid-Atlantic coastline and the result could be some more snow for the I-95 corridor region from DC-to-Philly-to-NYC.

Winds will pick up significantly on Tuesday night and continue strong on Wednesday with gusts to 40 mph possible and actual air temperatures will struggle to reach 30 degrees.
