Regional Weather: Eastern North America

Unsettled, summer-like weather. An unseasonably warm, humid, and wet weather scenario unfolds early this week. Tropical Depression Nate moved rapidly through the mid-South and Ohio Valley yesterday. He continues on this pace today through the Northeast accompanied by clouds and rain. Meanwhile, a front in the central U.S. pushes east. Showers will occur in the soupy air mass over eastern North America behind Nate and ahead of the front. Quite warm with highs well into the 70s and 80s, lows in the 50s to 70s.

 

OUTLOOK:

Overview: Epidemic spread likely in the South and lower mid-Atlantic. Transport events are tracking near-source and north or northeast. The summer-like, almost tropical weather is providing favorable conditions for survivable transport and deposition. Any dormant infections are experiencing a late-season revitalization and any active ones should remain active.
