    Weekend Forecast for Great Lakes and Northeast

    Thursday Morning

    Hot, humid weather will the rule this weekend from Illinois or Wisconsin south to the Gulf Coast. This is nothing new in the South, but will represent the longest period of very warm to hot weather (so far) this summer. Meanwhile, most of New England should be dry and at least partly sunny with afternoons in the comfortable 70s. Between the two air masses, there will be an unsettled contentious zone where thunderstorms will develop. This video may give you a better picture of what to expect.

    The next map shows the pressure pattern in the Northeast. It is very busy map with subtle looking but important boundaries. For example, the purple line in the east marks the boundary between air coming in from the ocean and a southwesterly current of warmer air. That boundary was the scene of showers and thunderstorms when it was in the middle of Pennsylvania yesterday, and was associated with rain that moved through the Hudson Valley early this morning. It could become the breeding ground for new showers and thunderstorms this afternoon and tonight along or near the I-95 corridor.
