AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
200 PM PDT WED JUL 5 2006

.SYNOPSIS...
SOUTHWEST FLOW ALOFT WILL BRING DRIER AIR INTO SOUTHERN CALIFORNIA
THURSDAY AND FRIDAY. IT WILL REMAIN VERY WARM THROUGH THE
WEEKEND...THEN TURN COOLER NEXT WEEK AS LOW PRESSURE APPROACHES FROM
THE PACIFIC NORTHWEST.

&&

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

THE ATMOSPHERE WAS A LITTLE DRIER AND MORE STABLE THAN YESTERDAY AND
STUNTED THE CLOUD GROWTH OVER THE MOUNTAINS THIS AFTERNOON.
HOWEVER...THUNDERSTORMS DID FORM OVER THE BAJA SPINE AROUND 1830Z.
WATER VAPOR LOOP SHOWED THE AXIS OF DEEP MOISTURE ON THE SOUTHEAST
BORDER OF THE CWA BETWEEN THE UPPER HIGH OVER NEW MEXICO AND THE
WEAK TROUGH OVER THE WEST COAST. THIS MOISTURE AXIS REMAIN NEARLY
STATIONARY THROUGH THE WEEKEND...SO ANY SMALL SHIFT TO THE WEST
COULD ADVECT SUFFICIENT MOISTURE FOR ISOLATED AFTERNOON
THUNDERSTORMS IN THE MOUNTAINS. WILL KEEP THE FORECAST DRY FOR
NOW...BUT WILL MONITOR NEXT COUPLE RUNS FOR POSSIBLE WEAK RETURN
FLOW OF MONSOON MOISTURE. IN ADDITION...THE GFS FORECASTS A CLOSED
UPPER LOW NEAR PT CONCEPTION OVER THE WEEKEND...AN ANOMALY FOR THIS
TIME OF YEAR. SOUTHERLY FLOW BETWEEN THIS LOW AND THE UPPER HIGH
OVER NEW MEXICO MAY ACT TO ENHANCE MONSOON MOISTURE ADVECTION INTO
SOUTHERN CALIFORNIA SATURDAY.

TEMPS WILL REMAIN ABOVE AVERAGE THROUGH THE WEEKEND. SLIGHTLY
STRONGER ONSHORE FLOW WILL SEND MARINE LAYER CLOUDS INTO THE COASTAL
ZONES EACH NIGHT BEFORE BURNING OFF TO THE COAST EACH DAY. MORE
SIGNIFICANT COOLING IS FORECAST NEXT WEEK AHEAD OF A STRONGER
PACIFIC TROUGH OVER THE PACIFIC NORTHWEST.
&&

.AVIATION...
LINGERING MOISTURE IN THE MTNS AND DESERTS SHOULD FIRE AT LEAST
ISOLATED THUNDERSTORM ACTIVITY THROUGH EARLY EVENING. STRONG
UDDFS...HAIL...AND ASSOCIATED TURBULENCE CAN BE EXPECTED IN THE
VICINITY OF THESE STORMS. WEST OF THE MTNS...EXPECT THE STRATUS
LAYER TO MOVE BACK ONTO THE COAST AFTER 03Z WITH MVFR CIGS/VIS BY
06Z AND CONTINUING THROUGH 16Z THU. SOME OF THE INLAND VALLEYS COULD
HAVE LOCAL IFR CONDITIONS. EXPECT BASES 1K TO 1.2K FT MSL AND TOPS
TO 1.8K FT. WINDS BELOW 15 KT THROUGH 15K FT...EXCEPT NEAR
CONVECTION.

.SGX WATCHES/WARNINGS/ADVISORIES...NONE.
