AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
200 PM PDT THU AUG 6 2015

.SYNOPSIS...

MONSOON MOISTURE AND SOME INSTABILITY WILL CONTINUE TO BRING
ISOLATED SHOWERS AND THUNDERSTORMS THIS AFTERNOON. ANY RAINFALL THAT
OCCURS WILL BE LIGHT. A TROUGH OF LOW PRESSURE WILL MOVE OUT THE
MONSOON MOISTURE AND BRING COOLER WEATHER FRIDAY AND SATURDAY. IT
WILL ALSO BRING BACK MORE COASTAL CLOUDS NIGHTS AND MORNINGS. FAIR
AND SEASONAL SUMMER WEATHER WILL CONTINUE NEXT WEEK.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

ISOLATED SHOWERS AND THUNDERSTORMS HAVE BEEN MOVING NORTHWARD MAINLY
THROUGH A CORRIDOR OFF THE COAST...INTO ORANGE COUNTY...THE
NORTHWEST INLAND EMPIRE...AND NORTH ALONG THE SAN BERN - LA COUNTY
LINE INTO THE DESERT. ONLY A COUPLE PLACES HAVE ACTUALLY MEASURED
RAINFALL...WITH ADELANTO TOPS AT 0.09 INCH. THERE HAVE BEEN A FEW
TSTORMS ELSEWHERE...BUT ISOLATED WITH NO MEASURABLE REPORTS YET.
ISOLATED DRY LIGHTNING IN THE MOUNTAINS IS A CONCERN...BUT WILL NOT
BE WIDESPREAD. THE PRECIP WILL DIMINISH AFTER SUNSET...IF NOT BEFORE
THEN...AS MOISTURE DECREASES FROM SOUTHWEST TO NORTHEAST. A LOW
PRESSURE TROUGH OFF THE CALIFORNIA COAST WILL PUSH EAST ACROSS THE
STATE TONIGHT INTO FRIDAY. THIS WILL PUSH ASIDE THE MONSOON MOISTURE
FOR QUICK DRYING OF THE ATMOSPHERE. IT WILL ALSO DEEPEN UP OUR
MARINE LAYER TO PRODUCE MORE EXTENSE COASTAL CLOUDS...PROBABLY
ENOUGH TO SNEAK INTO PARTS OF THE INLAND EMPIRE BY SUNRISE FRIDAY. A
SIMILAR DEPTH AND EXTENT TO COASTAL CLOUDS ARE EXPECTED SATURDAY.
COOLER WEATHER WILL COME TO THE ENTIRE REGION FRIDAY AND SATURDAY
WITH TEMPS CLOSE TO SEASONAL AVERAGE. SOME HIGH PRESSURE TRIES TO
REBUILD NEXT WEEK SO SLIGHTLY WARMER WEATHER IS EXPECTED...BUT A NEW
LOW PRESSURE TROUGH OFF THE COAST WILL DAMPEN THAT TREND. SOUTHERN
CALIFORNIA WILL REMAIN IN BETWEEN THE WESTERN TROUGH AND THE EASTERN
RIDGE WITH SOME SEASONAL WEATHER. SOME GUIDANCE SHOWS A FAVORABLE
POSITION OF THE HIGH PRESSURE RIDGE THAT WOULD BRING IN SOME MONSOON
MOISTURE AGAIN NEXT WEDNESDAY OR THURSDAY AND SMALL CHANCES OF
THUNDERSTORMS IN THE MOUNTAINS.
