Regional Weather: Southeast / mid-Atlantic U.S.

Sultry and unsettled. Scattered to numerous showers and storms are a daily occurrence late this week in our regions of interest. Temperatures will be very warm to hot, tempered only by increased cloud cover, with highs in the upper 80s and 90s and lows in the 70s. The Bermuda High anchoring this pattern will likely remain strong through the weekend.

 

OUTLOOK:

Overview: Epidemic spread likely. Rainfall in the upper Southeast / mid-Atlantic Wednesday and Thursday will serve to re-invigorate existing infections in those areas. Risks to cucurbits for Friday's transport events will be higher than those for Thursday for that reason. Transport events move north to northeast from most sources.
