FORECAST IS BASED ON IGNITION TIME OF 1100 EST ON DECEMBER 01.
IF CONDITIONS BECOME UNREPRESENTATIVE, CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...DRY WEATHER IS ANTICIPATED TODAY IN THE VICINITY OF
THE PRESCRIBED BURN SITE...AS THE REGION WILL REMAIN DOMINATED
BY A WEAKENING RIDGE OF HIGH PRESSURE LOCATED TO THE NORTH AND
EAST OF SOUTH FLORIDA. LIGHT TO MODERATE EASTERLY WINDS WILL
PREVAIL DURING THE AFTERNOON. ALTHOUGH HIGH LEVEL CLOUDS WILL
CONTINUE TO INCREASE THROUGH THE DAY...SUFFICIENT HEATING SHOULD
OCCUR NEAR THE SURFACE TO ALLOW AFTERNOON RH TO DROP INTO THE
40-45 PERCENT RANGE...WITH GENERALLY GOOD SMOKE DISPERSION
EXPECTED. SOME PATCHY FOG WILL BE POSSIBLE OVERNIGHT...BUT CHANCES
OF WIDESPREAD OR DENSE FOG ARE LOWER AS WINDS WILL BE INCREASING
FROM THE SOUTHEAST IN RESPONSE TO A STRONG AREA OF LOW PRESSURE
MOVING ONSHORE ALONG THE CENTRAL GULF COAST.
