.DISCUSSION...
A BACKDOOR COLD FRONT IN THE AREA COMBINED WITH AN APPROACHING
DISTURBANCE FROM THE NORTHWEST WILL RESULT IN A DECENT SHOT AT
SHOWERS AND THUNDERSTORMS TODAY...WITH SLIGHTLY COOLER TEMPERATURES
AND CONTINUED RELATIVELY HIGH HUMIDITY. DRIER AIR WILL BEGIN TO
WORK INTO THE AREA LATE TONIGHT...WITH WARMER TEMPERATURES AND
ONLY A VERY SLIM CHANCE FOR AN AFTERNOON AND EVENING THUNDERSTORM
THURSDAY.

ANOTHER DECENT CHANCE FOR SHOWERS AND THUNDERSTORMS IS EXPECTED
FRIDAY AFTERNOON AND FRIDAY NIGHT...AS A TROUGH AND ASSOCIATED
COLD FRONT MOVE ACROSS THE AREA. AT THE MOMENT...IT APPEARS THE
COLD FRONT WILL MOVE ACROSS THE WILDFIRE AREA AROUND MIDDAY ON
FRIDAY. THIS WILL RESULT IN BREEZY CONDITIONS DEVELOPING FRIDAY.
