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

Numerous showers will occur along the Gulf Coast and in parts of GA / AL. Scattered shower activity is expected elsewhere in the Southeast and in the mountains, the latter due to a cold front approaching from the west. Mostly dry in the mid-Atlantic. Highs in the 90s, lows well into the 70s.



Overview: Epidemic spread likely in parts of the Southeast. Transport events track near-source and north to northwest each day.
