EXTREME SOUTHWESTERN CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CALIFORNIA
230 PM PDT SUN AUG 10 2003

.SYNOPSIS...STRONG UPPER LEVEL HIGH PRESSURE OVER THE WEST WILL
GRADUALLY WEAKEN AS AN UPPER TROUGH OVER THE EASTERN PACIFIC MOVES
OVER THE PACIFIC NORTHWEST.  THERE WILL BE AN INCREASE IN THE
MARINE LAYER LOW CLOUDS AND FOG...MAINLY OVER THE COASTAL PLAIN...AS
THE ONSHORE FLOW SLOWLY DEVELOPS.

.DISCUSSION...LOOKS LIKE A CHANGE IS IN THE WORKS.  THE UPPER LEVEL
HIGH IS EXPECTED TO FINALLY BREAK DOWN AND RELEASE ITS GRIP ON THE
WEST. ALSO THE ONSHORE LOW LEVEL FLOW SHOULD INCREASE.  THIS WILL COOL
THE COASTAL AREAS SOMEWHAT MONDAY...BUT INLAND AREAS WILL SEE ANOTHER
DAY SIMILAR TO TODAY. A SLOW COOLING TREND WILL KNOCK DOWN
TEMPERATURES ALL AREAS TUESDAY INTO THE WEEKEND AS THE TROUGH ENTERS
THE PACIFIC NORTHWEST AND THE ONSHORE FLOW STRENGTHENS.  THE MARINE
LAYER SHOULD DEEPEN ENOUGH TO PUSH SOME LOW CLOUDS TO THE WESTERN EDGE
OF THE SOUTHERN VALLEYS BY MIDWEEK. THERE COULD BE A PERSISTENT MARINE
LAYER LOW CLOUDS AND FOG DECK AT THE BEACHES BEGINNING TUESDAY.

SAN...NONE.
