DISCUSSION
VERY HOT CONDITIONS WILL OCCUR TODAY AND MONDAY WITH AN EXTREME
HEAT WARNING IN EFFECT BOTH DAYS. THE PREVIOUS FIRE WEATHER WATCH
THAT WAS ISSUED SATURDAY AFTERNOON WAS UPGRADED THIS MORNING FOR
THE FIRE WEATHER ZONE ENCOMPASSING THIS FORECAST LOCATION SO THERE
IS NOW A RED FLAG WARNING IN EFFECT TODAY. EVEN AS WINDS SLOWLY
DECREASE AFTER SUNSET TONIGHT, EXPECT SOME MIXING TO REMAIN WITH
WINDS STILL 5-10 MPH GUSTING TO 15 MPH OVERNIGHT TONIGHT. RECOVERY
RHS TONIGHT SHOULD BE FAIR, AROUND 70% BEING FORECAST. EVEN WITH
THE RED FLAG WARNING FOR TODAY, THE FIRE WEATHER WATCH IN EFFECT
CURRENTLY FOR MONDAY IS ACTUALLY THE MORE HIGH CONFIDENCE TIME ON
PROLONGED AND SIGNIFICANT CRITICAL FIRE WEATHER CONDITIONS. THERE
WILL HAVE BEEN MULTIPLE DAYS OF VERY HOT TEMPERATURES AND INTO AT
LEAST DAY 2 OF RELATIVELY LOW AFTERNOON RHS (DOWN TO THE LOW-20S
IS FORECAST TOMORROW). WESTERLY WIND ALSO INCREASE IN SPEED MONDAY
COMPARED TO SUNDAY.

FORECAST LOCATION EARLY TUESDAY MORNING AND WILL CREATE A WIND
SHIFT TO WESTERLY THEN NORTHWESTERLY BY TUESDAY MID-DAY. WIND
SPEEDS WILL ALSO BE SLOWER TUESDAY, BUT RELATIVE HUMIDITY REMAINS
