.DISCUSSION...
A FEW SHOWERS AND THUNDERSTORMS WILL LINGER ACROSS THE FIRE AREA
THIS MORNING IN THE WAKE OF THE DISTURBANCE ALOFT AND ASSOCIATED
WEAK COLD FRONT EXITING THE AREA TO THE EAST. OTHERWISE...HIGH
PRESSURE ALOFT WILL REBUILD INTO THE AREA TODAY FOR MOSTLY SUNNY
SKIES IN THE AFTERNOON WITH TEMPERATURES ABOUT 3 TO 5 DEGREES
COOLER THAN YESTERDAY...BUT WITH SIMILARLY LOW RELATIVE HUMIDITY.
WINDS WILL ALSO BECOME BREEZY OUT OF THE NORTHWEST IN THE WAKE OF
THE FRONT. ANOTHER DISTURBANCE ALOFT WITH AN ASSOCIATED FRONTAL
BOUNDARY WILL THEN GRADUALLY APPROACH THE FIRE AREA FROM THE
SOUTHWEST OVERNIGHT AND INTO THE DAY ON FRIDAY. THIS SYSTEM WILL
BRING AN INCREASING CHANCE OF SHOWERS AND THUNDERSTORMS TO THE AREA
BEGINNING AFTER MIDNIGHT TONIGHT AND CONTINUING INTO FRIDAY...AS
WINDS SHIFT MORE EASTERLY. HUMIDITY RECOVERY TONIGHT WILL LIKELY
BE ONLY MODERATE...WITH CONTINUED VERY WARM AND DRY CONDITIONS ON
