.DISCUSSION...
The burn site will remain between high pressure centered over the
northern Gulf of Mexico and lee trough across the southern and
middle Appalachians. This pattern will support strengthening
southwest winds through this afternoon. As temperatures peak in the
upper 50s this afternoon, the mixed layer should deepen to around 5 kft.
Momentum transfer should result in gusts between 20-25 mph through
this afternoon. In addition, dewpoints are forecast to remain in
the upper 20s this afternoon, resulting in RH values less the 35
percent this afternoon. A dry and cool air mass will settle over the
area tonight.

Fog potential for tonight: None
