...MARGINALLY HIGH DAYTIME DISPERSION VALUES THIS AFTERNOON...
...ROUNDS OF HEAVY DOWNPOURS AND LOCALIZED FLOODING ON WEDNESDAY
AND WEDNESDAY NIGHT...

.DISCUSSION...

Dry weather will continue at the burn site through early this
evening. Breezy southeasterly transport winds at ignition time
will quickly shift to southerly by the mid to late morning hours.
Southeasterly surface winds will become breezy by the mid-morning
hours, with winds then shifting to southerly towards noon. These
breezy conditions will result in marginally high daytime dispersion
values this afternoon. Chances for showers and thunderstorms will
increase towards midnight, with waves of slow moving downpours and
potentially strong thunderstorms expected through Wednesday night.
Rainfall amounts of 2-3 inches are expected at the burn site by
early Thursday morning. Breezy southerly transport winds outside of
thunderstorm activity will yield poor daytime dispersion values on
Wednesday due to extensive cloud cover and rainfall.
