BELOW NORMAL TEMPERATURES NEXT WEEK AS A LOW PRESSURE SYSTEM
DEVELOPS ALONG THE CALIFORNIA COAST. NO PRECIPITATION EXPECTED.

&&

.SHORT TERM (TODAY-SUN)...CLOUDS HAVE MOSTLY EXITED THE AREA THIS

CLOUDY SKIES. SO FAR NOT EVEN A HINT OF CONVECTION EXCEPT FOR A FEW
CLOUDS OVER THE HIGHEST PEAKS. UNLESS DEVELOPMENT INCREASES
SIGNIFICANTLY IN THE NEXT HOUR WILL LIKELY REMOVE TSTORMS FROM THE
FORECAST TODAY AND TOMORROW AS WELL SINCE CONDITIONS DON`T LOOK ANY
MORE FAVORABLE THEN.

ROBUST 5 MB ONSHORE TREND. COULD SEE CLOUDS INTO THE LOWER VALLEY
LOCATIONS BY SUNRISE. A SLIGHT COOLING TREND EXPECTED FOR MOST AREAS
AS WELL WITH VALLEYS TOPPING OUT IN THE 80S TO LOWER 90S AND COASTAL
AREAS MOSTLY IN THE 70S.

NOT MUCH CHANGE THROUGH THE WEEKEND. PROBABLY A FEW CLOUDS OVER THE
MTN PEAKS EACH DAY BUT OTHERWISE DRY. MIGHT SEE A VERY SLIGHT WARMUP
SUNDAY DUE TO A BIT WEAKER ONSHORE FLOW.

.LONG TERM (MON-THU)...A TROUGH WILL DOMINATE THE CALIFORNIA WEATHER
PATTERN NEXT WEEK, MEANING A RETURN TO EARLY SUMMER WEATHER. MARINE
LYR WILL MOVE INTO THE VALLEYS EACH NIGHT AND CLEAR TO NEAR THE
COAST EACH DAY. TEMPS SLIGHTLY BELOW NORMAL AND NO THREAT OF
CONVECTION.
