During the next 1-2 weeks, the upper air pattern will feature a ridge near the West Coast and a deep trough over or east of the Great Lakes. This is a classic setup for cold weather in the Great Lakes and Northeast... and it favors periodic jabs of cold air all the way to the Gulf Coast.
The weekend will be moderately chilly in the I95 corridor from Maryland to Maine. A low pressure area that develops along a cold front is somewhat of a wild card. Most computer models suggest there will be at least some wet snow and rain tonight in the Middle Atlantic states and in central and eastern New England tomorrow. In both areas, snow is the most likely form of precipitation west and north of the major cities. This idea is reflected in the GFS snow accumulation map, which predicts the total snowfall between now and Sunday morning. The disturbance that would cause this is quite strong as it emerges from the Ohio Valley. In fact, some of the snow squalls can even contain lightning and thunder from southern Ohio and West Virginia to the middle of Pennsylvania today.
