.DISCUSSION...

Conditions remain warm and dry, but stable. This will favor lower
dispersions today, but they will continue to increase over the next
couple days. Even though no rain is in the forecast, a SE flow
continues to keep just enough moisture in place to keep RH values
above critical thresholds. No red flag conditions are anticipated
a this time.
