EXTREME SOUTHWESTERN CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
915 AM PDT FRI AUG 10 2001

                             ...SYNOPSIS...
STRONG HIGH PRESSURE WILL CONTINUE OVER THE REGION THIS WEEKEND AND
REMAIN STRONG MOST OF NEXT WEEK. AFTERNOON CLOUDS AND A CHANCE OF
THUNDERSTORMS WILL INCREASE OVER THE MOUNTAINS AND DESERTS OVER THE
WEEKEND. COASTAL CLOUDINESS WILL CONTINUE NIGHTS AND MORNINGS...BUT
WILL BE LESS EXTENSIVE.

                            ...DISCUSSION...
AT 12Z...BASE OF INVERSION AT 1.6 KFT AND STRENGTH OF INVERSION
ABOUT 9 DEGREES. SHOULD CLEAR COMPLETELY AT MOST IF NOT ALL BEACHES
TODAY. NEW MARINE ZONE LAUNCHED IN MARINE FORECAST WITH 930 AM
ISSUANCE...SEE LAXCWFSGX.

STRONG UPPER HIGH OVER SOCAL WATERS PUTTING OUR AREA IN WEAK NE FLOW
TODAY. CORRESPONDING SUBSIDENCE WILL MAKE CONVECTION ANEMIC SO
PARTLY CLOUDY LOOKS OK FOR THIS AFTERNOON. K-F CONVECTIVE MODEL
CONFIRMS THIS IDEA. A SMALL INCREASE IN UPPER LEVEL MOISTURE
EXPECTED SAT MAY SET OFF A FEW TSTORMS...BUT STILL LOOKS INHIBITED.
BY SUN THE HIGH IS OVER THE 4 CORNERS. ALSO A DEEPER WETTER LAYER
AND AN EASTERLY WAVE ARRIVES SUN BRINGING A MUCH BETTER CHANCE OF
TSTORMS. TEMPS SHOULD INCREASE NEARLY EVERYWHERE THROUGH SAT...BUT
DECREASE A LITTLE SUN IN MTNS/DESERTS DUE TO HIGHER HUMIDITIES AND
GREATER CLOUD COVER. SAME UPPER LEVEL PATTERN PROGGED BY EXTENDED
MODELS TO CONTINUE ALL NEXT WEEK...UPPER HIGH OSCILLATING BETWEEN 4
CORNERS AND SOCAL AND FLUCTUATIONS IN MOIST MONSOONAL FLOW INTO
THE REGION.

.SAN...NONE.
