.DISCUSSION...

CURRENT SATELLITE DEMONSTRATES SOME DEVELOPING CLOUDS OVER THE
FIRE THIS AFTERNOON. INCREASED INSTABILITY THIS EVENING WILL ALLOW
FOR ISOLATED SHOWERS AND THUNDERSTORMS...WITH GUSTY AND ERRATIC
WIND BEING POSSIBLE ALONG WITH LIGHTNING. SHOWER ACTIVITY WILL
THEN TAPER OFF WITH THE LOSS OF DAYLIGHT THIS EVENING...BUT
ANOTHER PUSH OF MONSOONAL MOISTURE WILL CREATE ANOTHER ROUND OF
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS OVER THE FIRE ON
SUNDAY. IN ADDITION...THE AXIS OF THE RIDGE OF HIGH PRESSURE WILL
MOVE EAST OF THE FIRE BY SUNDAY AFTERNOON WITH AN INCREASE OF WEST
TO SOUTHWESTERLY FLOW. EXPECT SLIGHTLY COOLER TEMPERATURES ON
SUNDAY...WITH INCREASED DAYTIME HUMIDITY DUE TO THE ARRIVAL OF
INCREASED MONSOONAL MOISTURE.
