Becoming Warmer During Last Week of Summer

Monday 9 a.m.

A cold front moving through the Northeast is causing rain, but another large high pressure area is poised to take over in the Northeast by tonight. Northerly flow ahead of the high pressure area will bring in cooler air for tonight and tomorrow, but southerly winds behind the high will make it warmer Wednesday through Friday. The video has more.

It will turn humid across the western Great Lakes region on Wednesday, and a weak disturbance rippling through aloft may cause raise the chance of thunderstorms there. In the Middle and North Atlantic states, it will become warmer from Wednesday through Friday. After today, it seems unlikely to rain in the I95 corridor until the next cold front approaches late Friday or Saturday.

This pressure analysis suggests the cold front was on a line from Pennsylvania to Kentucky at 7 a.m. EDT.
