Canadian high pressure will continue to control our weather through tomorrow and temperatures will remain well below normal. In fact, in the wake of Sandy, the Mid-Atlantic region has been incredibly persistent with clouds and cold and the relatively new month so far is averaging well below normal temperatures. Meanwhile, with cold air already established, the ingredients are there for a powerful Nor'easter to pound the Mid-Atlantic region from Wednesday into Thursday, and this storm will not only generate rain and wind, but snow as well.
An offshore storm will develop just off the Southeast US coast on Tuesday and then it will ride slowly northward along the east coast reaching near a position just east of the Delaware Bay by Wednesday evening. This track will bring rain and wind to coastal regions and significant snows in inland locations from central Maryland/Virginia northward into Maine. There is even the chance that the rain changes to accumulating snow in or near the big cities along the I-95 corridor as the storm pulls to the northeast by later Wednesday or Wednesday night. Winds will gust out of the northeast up to 50 mph along the I-95 corridor with even highers gusts at the coastline. Once this system passes by, the overall pattern will change for awhile and there will be significant improvement by the latter part of the weekend with noticeably milder conditions.
