Discussion
The coldest core of this most recent Arctic air outbreak has moved into the Mid-Atlantic region and Northeast US following the overnight passage of a frontal system. As a result, temperatures today will be confined to the 20’s for highs – well below normal for early March – and strong winds will generate even lower wind chill values. In addition, instability in the atmosphere could result in some snow shower activity; primarily, across northern suburbs and there may even be an isolated snow squall. The next low pressure system of note to monitor will trek across the nation over the next couple of days and it can produce some snow here on Friday. The upper-level energy supporting this system will get somewhat “stretched out” over the next couple of days, but the chance for small snow accumulations is on the table for Friday in the DC-to-Philly-to-NYC corridor. A more important system will head towards the Great Lakes this weekend and likely push rain into the region by early Sunday and there is a chance for some frozen precipitation at the onset in some nearby higher elevation locations such as east-central and NE PA.
