With the Arctic cold front well off the coast this morning, the main story to end the week will be the presence of brutally cold air over the Philadelphia and New York City metropolitan areas. Temperatures today will struggle in the 10's and 20's with a biting northwester wind. The Arctic air will exit rather quickly this weekend but will be followed by the potential for a major winter storm with a wide variety of storm impacts.
Today through tomorrow, high pressure will move through the northern Mid Atlantic with generally clear skies. A few snow showers will be possible as weak disturbances pass through the region.

As the Arctic front stalls to the south of New Jersey, another disturbance will approach from the west producing periods of snow, sleet, and rain Sunday night on through Monday and into Tuesday morning. Significant snowfall is expected from this low pressure system along with ice, however the exact details on snowfall accumulations are still uncertain.
