.DISCUSSION...
HIGH PRESSURE WILL KEEP BENIGN CONDITIONS OVER THE FIRE THIS MORNING
WITH GENERALLY LIGHT WIND AND WARMING TEMPERATURES. THESE BENIGN
CONDITIONS WILL CONTINUE UNTIL THE AFTERNOON HOURS EVEN AS THE AXIS
OF THE RIDGE OF HIGH PRESSURE BEGINS TO MOVE EAST  AHEAD OF AN
ARRIVING COLD FRONT. THIS WILL RESULT IN A MORE SOUTHWESTERLY FLOW
OVER THE FIRE WITH INCREASED WIND AND INCREASED MOISTURE TO
INTRODUCE A FEW SHOWERS OVER THE FIRE. THE FRONT IS THEN EXPECTED TO
MOVE THROUGH THE FIRE LATE MONDAY MORNING INTO MONDAY AFTERNOON.
THIS FRONT WILL CONTINUE ISOLATED SHOWERS THROUGH MONDAY. COOLER
TEMPERATURES WITH INCREASED HUMIDITY ARE EXPECTED BY MONDAY
AFTERNOON.
