Regional Weather: Southern U.S.

Unsettled weather most areas. The current situation is common summertime weather: sunny to partly cloudy skies and a chance of mainly afternoon and evening showers or storms in many locations. Showers will be more numerous toward the eastern sections. Many areas west of the MS River will be dry. Hot for mid-June with highs mostly in the 90s, lows mostly 70s.



Overview: Epidemic spread likely in the Southeast and lower mid-Atlantic. The environment supports survivable transport and deposition of airborne spores from the sources along the southern East Coast of the United States. Transport events are moving near-source and/or to the ENE / northeast from these outbreaks. The TX transport events are associated with unfavorable conditions during mid-week. Conditions will remain generally favorable for epidemic spread in the Southeast and mid-Atlantic regions through at least the upcoming weekend.
