...RECORD-BREAKING HEAT WILL LIKELY RETURN TO SOUTHWESTERN
CALIFORNIA THIS WEEKEND...

A STRONG RIDGE OF HIGH PRESSURE WILL BUILD INTO THE WEST COAST TONIGHT
AND SATURDAY...THEN INTENSIFY SUNDAY AND MONDAY. SIGNIFICANT WARMING
WILL BEGIN ACROSS MUCH OF SOUTHWESTERN CALIFORNIA SATURDAY...AND
ADDITIONAL WARMING SUNDAY WILL BRING TEMPERATURES TO NEAR RECORD
OR RECORD LEVELS IN MANY AREAS. THE HEAT WILL CONTINUE THROUGH
MONDAY BEFORE GRADUAL COOLING BEGINS ACROSS THE AREA ON TUESDAY.

AT THE SAME TIME...HIGH PRESSURE AT THE SURFACE WILL BUILD INTO THE
GREAT BASIN...CAUSING WEAK OFFSHORE FLOW DURING AT LEAST THE NIGHT
THROUGH MORNING HOURS. ALTHOUGH WIDESPREAD GUSTY OFFSHORE WINDS ARE
NOT EXPECTED AT THIS TIME...THE COMBINATION OF A PROLONGED PERIOD OF
VERY HIGH TEMPERATURES AND VERY LOW RELATIVE HUMIDITIES WILL CREATE A
HEIGHTENED FIRE DANGER ACROSS THE REGION THIS WEEKEND...CONTINUING
THROUGH EARLY NEXT WEEK.

THE WEAK OFFSHORE FLOW WILL ALSO HELP DELAY THE ONSET OF COOLING
SEABREEZES EACH OF THE NEXT FEW DAYS...ALLOWING HOT WEATHER TO
SPREAD ACROSS MUCH OF THE COASTAL PLAIN...AND POSSIBLY TO THE
IMMEDIATE BEACHES AS WELL.

HIGH TEMPERATURES ON SATURDAY ARE EXPECTED TO RISE INTO THE
LOWER TO MID 90S IN THE VALLEYS...IN THE FOOTHILLS OF THE MOUNTAINS...
AND ACROSS THE ANTELOPE VALLEY. ON THE COASTAL PLAIN...HIGHS SATURDAY
SHOULD RANGE FROM THE 70S AT THE BEACHES TO THE MID TO UPPER 80S
ACROSS INLAND SECTIONS OF THE COASTAL PLAIN.

THE HEAT IS EXPECTED TO PEAK ACROSS THE AREA SUNDAY AND MONDAY.
ON THOSE DAYS...HIGH TEMPERATURES ARE EXPECTED TO RISE TO BETWEEN
95 AND 105 IN THE VALLEYS...IN THE 90S TO AROUND 100 IN THE FOOTHILLS
OF THE MOUNTAINS...ACROSS THE ANTELOPE VALLEY...AND ACROSS INLAND
SECTIONS OF THE COASTAL PLAIN. CLOSE TO THE IMMEDIATE COAST...AND
AT THE BEACHES...HIGHS ARE EXPECTED TO BE MAINLY IN THE 80S...
ALTHOUGH TEMPERATURES IN SOME BEACH COMMUNITIES MAY SOAR INTO THE
LOWER TO MID 90S AS WELL.
