...HOT WEATHER ON TAP BY MIDWEEK FOR MUCH OF SOUTHWESTERN 
CALIFORNIA...

AN UPPER LEVEL HIGH PRESSURE SYSTEM WILL BUILD OFF THE CENTRAL COAST 
BY WEDNESDAY...THEN IT WILL STRENGTHEN AS THE MAIN CORE OF THE HIGH 
BECOMES ANCHORED OVER CENTRAL AND NORTHERN CALIFORNIA THURSDAY 
THROUGH FRIDAY. WEAK TO MODERATE OFFSHORE FLOW WILL DEVELOP BY 
TUESDAY MORNING...HELPING TO WARM TEMPERATURES TO NEAR NORMAL FOR 
THIS TIME OF YEAR. 

AS THE UPPER LEVEL HIGH PRESSURE SYSTEM BUILDS OVER CALIFORNIA
AND WEAK OFFSHORE FLOW PERSISTS WEDNESDAY MORNING...THERE WILL
BE ADDITIONAL WARMING ACROSS MOST AREAS ON WEDNESDAY...ESPECIALLY
INTERIOR SECTIONS. MANY VALLEY...LOWER MOUNTAIN...AND DESERT LOCATIONS
WILL CLIMB WELL INTO THE 80S ON WEDNESDAY...WITH WARMER LOCATIONS
SOARING INTO THE LOWER 90S. ONSHORE FLOW IS PROJECTED WEDNESDAY
AFTERNOON...WHICH WILL HELP TO MODERATE TEMPERATURES NEAR THE COAST.

THE HOTTEST DAYS WILL BE THURSDAY AND FRIDAY AS OFFSHORE FLOW BECOMES
MORE PRONOUNCED AND THE BOUNDARY LAYER CONTINUES TO WARM WITH TIME.
TEMPERATURES WILL SOAR WELL INTO THE 90S ACROSS MOST INTERIOR
SECTIONS...WITH SOME OF THE HOTTEST LOCATIONS EXPECTED TO CLIMB
TO OVER 100 DEGREES. AT THIS TIME...IT APPEARS THAT THE OFFSHORE
INFLUENCE WILL AFFECT PORTIONS OF THE COASTAL PLAIN ON THURSDAY
AND FRIDAY. AREAS NEAR THE IMMEDIATE COAST WILL LIKELY CLIMB INTO
THE 80S...WHILE INLAND PORTIONS OF THE COASTAL PLAIN WILL LIKELY
SOAR INTO THE 90S. SOME RECORD HIGH TEMPERATURES ARE LIKELY THURSDAY
AND FRIDAY. 

DURING THE HOT SPELL...RELATIVE HUMIDITY LEVELS WILL LIKELY LOWER
TO AROUND 10 PERCENT IN MANY VALLEY AND MOUNTAIN LOCATIONS...AS WELL 
AS THE ANTELOPE VALLEY. THIS COULD BRING POTENTIALLY DANGEROUS FIRE 
CONDITIONS TO MANY PORTIONS OF SOUTHWESTERN CALIFORNIA BY 
WEDNESDAY...WITH THE THREAT CONTINUING THROUGH AT LEAST FRIDAY.

AT THIS TIME...IT APPEARS THAT TEMPERATURES WILL CONTINUE TO BE 
QUITE WARM ON SATURDAY AND SUNDAY. HOWEVER...THE UPPER HIGH SHOULD 
WEAKEN A BIT...AND THERE WILL BE A QUICKER RETURN OF THE SEABREEZE 
EACH AFTERNOON...WHICH SHOULD COOL AT LEAST COASTAL REGIONS. INLAND 
TEMPERATURES WILL CONTINUE TO BE RELATIVELY HOT...WITH HIGHS IN THE 
LOWER TO MID 90S IN MOST AREAS. MORE SIGNIFICANT COOLING WILL LIKELY 
OCCUR EARLY NEXT WEEK.

PEOPLE PLANNING OUTDOOR ACTIVITIES LATER THIS WEEK INTO THE WEEKEND 
SHOULD TAKE INTO CONSIDERATION THE VERY HIGH TEMPERATURES AND ADJUST 
THEIR ACTIVITIES ACCORDINGLY. WEAR LOOSE FITTING LIGHT WEIGHT 
CLOTHING AND DRINK PLENTY OF WATER. TAKE ADVANTAGE OF SHADE AND
AIR CONDITIONING IF AVAILABLE.

NEVER...EVER LEAVE CHILDREN...THE ELDERLY OR PETS IN ENCLOSED 
AUTOMOBILES...EVEN FOR THE SHORTEST TIME. TEMPERATURES QUICKLY RISE 
TO LIFE-THREATENING LEVELS...EVEN IF THE WINDOWS ARE PARTIALLY 
OPENED.
