.DISCUSSION...
A FEW WEAK THUNDERSTORMS WILL BE POSSIBLE AT THE FIRE SITE THROUGH
EARLY EVENING. THIS ACTIVITY WILL REMAIN VERY ISOLATED AND WILL
LIKELY NOT AMOUNT TO MUCH PRECIPITATION. WINDS WILL BE GUSTY AT
TIMES IN AND AROUND THESE THUNDERSTORMS. RELATIVE HUMIDITIES WILL
CONTINUE TO FALL TO NEAR CRITICAL VALUES THIS AFTERNOON ALONG WITH
SOME INCREASINGLY GUSTY WEST WINDS. THESE WINDS SHOULD CALM SOME
OVERNIGHT...BUT STILL MAY STAY BREEZY ESPECIALLY IN EXPOSED
SECTIONS OF THE FIRE WHICH WILL LIMIT HUMIDITY RECOVERIES. DRIER
AIR WILL MOVE INTO THE REGION ON TUESDAY ALONG WITH SOME BREEZY
AFTERNOON WINDS. A FIRE WEATHER WATCH HAS BEEN POSTED ON TUESDAY
FOR FIRE WEATHER ZONE 302...WHICH IS JUST NORTHWEST OF THE FIRE.
