.DISCUSSION...

High pressure over the eastern Gulf and over the west Atlantic will
lead to lighter winds, generally out of the west to northwest around
5 mph. However, wind direction could be somewhat variable through the
day due to the weaker wind flow across the area. Higher mixing heights
through the afternoon, and west-northwest transport winds increasing
to 5 to 10 mph will lead to good to very good dispersion values into
the afternoon. Drier conditions and warmer than normal high
temperatures today will produce min RH values near critical values in
the mid 30s at the burn site.

Patchy fog will be possible late tonight into early Saturday morning.
Any lingering smoke from the burn overnight could mix with fog that
develops to produce limited visibilities along any nearby roadways.
