.DISCUSSION...

.THURSDAY...

WHILE DRIER CONDITIONS ARE EXPECTED WITH RH VALUES FALLING TOWARDS
30 PERCENT THURSDAY AFTERNOON...WE SHOULD REMAIN ABOVE CRITICAL RH
THRESHOLDS. WINDS WILL BE MAINLY OUT OF THE NORTH AS HIGH PRESSURE
MOVES INTO THE REGION BEHIND TODAY`S FRONTAL PASSAGE. WHILE 20-FT
WINDS MAY BE BREEZY IN THE MORNING...THEY SHOULD START TO RELAX IN
THE AFTERNOON AS THE HIGH PRESSURE CENTER MOVES CLOSER TO THE
STATE. EITHER WAY...YOUR SW ASPECT SHOULD HELP TO SHELTER
THROUGHOUT YOUR BURN...AND DISPERSION RATES LOOK TO HELP AS WELL.
