Regional Weather: Eastern U.S.

Active, transitional period. A significant change in the upper-level pattern will drive an unseasonably strong frontal system through the eastern U.S. over the next several days. Clouds, showers, and rain will impact the Northeast and upper mid-Atlantic on Monday, all the Eastern states on Tuesday, and the Southeast on Wednesday. High pressure from Canada builds in after the front passes accompanied by cooler, drier weather. Hot temperatures with highs / lows in the 90s/70s drop dramatically behind the front to 70s-80s / 50s-60s.

OUTLOOK:

Overview: Epidemic spread likely. On Monday and Tuesday ... transport events track east or northeast. Favorable conditions progress south and east with the front. The greatest impacts will be on Tuesday when growing areas from New England to FL will be at High Risk. On Wednesday ... many events move south / southwest as the winds shift behind the front. The more favorable weather is confined to the Southeast.
