Northeast: Hotter Today, Then Cooler

Wednesday morning

Hot, humid air is in place along the I-95 corridor today, but a cold front advancing southeastward from the eastern Great Lakes will ease the heat tomorrow. Friday and Saturday should be bright days with low to moderate humidity from Philadelphia on past Boston. However, another batch of very cool air aloft is likely to reach the Great Lakes Sunday and dominate the Northeast during at least the early part of next week. As the ground-level cold front associated with this feature moves along, it could kick off some strong thunderstorms. We'll follow up on that idea as we go through the next few days. Here is today's forecast video:

This map from 5 a.m. ET shows the cold front that is continuing toward this Northeast and Middle Atlantic states. Temperatures stayed in the 70s all night ahead of the front, but the air turned noticeably cooler after the front moved through.
