AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
320 AM PDT MON APR 29 2013

.SYNOPSIS...
A TROUGH OF LOW PRESSURE MOVING FROM THE PACIFIC NORTHWEST TODAY
INTO THE NORTHERN ROCKIES AND GREAT BASIN TUESDAY WILL BRING
STRONGER ONSHORE FLOW WITH DEEPENING OF THE MARINE LAYER INTO THE
FAR INLAND VALLEYS...LOCALLY GUSTY WEST WINDS TO AROUND 35 MPH IN
THE MOUNTAINS AND DESERTS...AND COOLING. FOR WEDNESDAY THROUGH
FRIDAY...HIGH PRESSURE OFF THE WEST COAST WILL BRING WARMING WITH
THE WARMEST DAYS FOR INLAND AREAS THURSDAY AND FRIDAY. SURFACE HIGH
PRESSURE OVER THE GREAT BASIN WILL BRING LOCALLY GUSTY NORTH TO
NORTHEAST WINDS TO AROUND 40 MPH THURSDAY MORNING WITH WEAKER WINDS
NEAR THE COASTAL FOOTHILLS FOR WEDNESDAY AND FRIDAY MORNINGS. THE
MARINE LAYER WILL KEEP COASTAL AREAS COOLER. FOR NEXT WEEKEND...A
TROUGH OF LOW PRESSURE FROM THE NORTH WILL MOVE INTO THE SOUTHWEST
STATES BRINGING A RETURN OF ONSHORE FLOW WITH COOLING AND A RETURN
OF COASTAL NIGHT AND MORNING LOW CLOUDS AND FOG.

&&

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

.SHORT TERM (TODAY THROUGH WEDNESDAY)...
A TROUGH OF LOW PRESSURE MOVING THROUGH SOUTHERN BRITISH COLUMBIA
AND THE PACIFIC NORTHWEST WILL MOVE SOUTHEASTWARD INTO THE NORTHERN
ROCKIES AND GREAT BASIN THROUGH TUESDAY AND INTO THE CENTRAL ROCKIES
WEDNESDAY. THIS WILL BRING INCREASING ONSHORE FLOW AND DEEPENING OF
THE MARINE LAYER INTO TUESDAY WITH COOLING...NIGHT AND MORNING
COASTAL LOW CLOUDS FOG EXTENDING INTO THE WESTERN VALLEYS THIS
MORNING...INTO THE FAR INLAND VALLEYS FOR TONIGHT INTO TUESDAY
MORNING....AND INTO PORTIONS OF THE INLAND VALLEYS FOR TUESDAY NIGHT
INTO WEDNESDAY MORNING...WITH LOCALLY GUSTY WEST WINDS IN THE
MOUNTAINS AND DESERTS. WINDS ARE EXPECTED TO BE STRONGEST LATE
TUESDAY AFTERNOON INTO TUESDAY EVENING AND MIGHT LOCALLY...BRIEFLY
APPROACH WIND ADVISORY CRITERIA BELOW THE BANNING PASS. LOCALLY
GUSTY NORTH WINDS WILL DEVELOP NEAR THE COASTAL FOOTHILLS WEDNESDAY
WHICH SHOULD BRING SLIGHT COASTAL WARMING AND A LITTLE GREATER
INLAND VALLEY AND COASTAL FOOTHILL WARMING FOR WEDNESDAY.

&&

.LONG TERM (WEDNESDAY NIGHT THROUGH SUNDAY)...
HIGHER RESOLUTION LOCAL MODELS SHOW THE MARINE LAYER REMAINING
SUFFICIENTLY DEEP WEDNESDAY EVENING FOR COASTAL STRATUS TO EXTEND
INTO THE WESTERN VALLEY WITH THE INLAND EDGE ERODING SOME TOWARD
THURSDAY MORNING AS NORTHEAST FLOW ALOFT DEVELOPS. MODEL GUIDANCE
CONTINUES TO TREND WEAKER WITH OFFSHORE FLOW FOR THURSDAY...BUT
LOCAL WIND GUIDANCE WITH INPUT FROM THE ECMWF AND GFS BOTH STILL
SUPPORT LOCAL GUSTS IN THE WINDIEST LOCATIONS TO AROUND 45 MPH...LOW
END ADVISORY STRENGTH...BELOW THE CAJON PASS AND IN THE COASTAL
FOOTHILLS OF THE SANTA ANA MOUNTAINS WITH LOCALLY GUSTY NORTHEAST
WINDS IN OTHER COASTAL FOOTHILL AREAS AS WELL. THE WARMEST DAYS FOR
INLAND AREAS SHOULD BE THURSDAY AND FRIDAY. HIGH TEMPERATURE
FORECASTS FOR COASTAL AREAS HAVE BEEN COOLED SOME FROM PREVIOUS
FORECASTS ON ACCOUNT OF WEAKER OFFSHORE FLOW AND RESULTING GREATER
RESIDUAL MARINE INFLUENCE. HIGH TEMPERATURE FORECASTS FOR THURSDAY
THROUGH SATURDAY ARE CLOSER TO THE MOS FOR THE 00Z DETERMINISTIC
ECMWF AND A LITTLE BELOW THE 50 PERCENT VALUE FOR THE ECMWF ENSEMBLE
MOS. FOR SATURDAY...THE GLOBAL MODELS ARE IN SOMEWHAT BETTER
AGREEMENT IN MOVING A LOW PRESSURE SYSTEM SOUTHWARD THROUGH THE
WESTERN STATES INTO THE GREAT BASIN. THIS WOULD BRING A RETURN OF
ONSHORE FLOW AND COOLING. HOWEVER...THE GLOBAL MODELS STILL HAVE
SIZABLE DIFFERENCES UPSTREAM OVER THE NORTHEAST PACIFIC AND
DOWNSTREAM OVER THE CENTRAL STATES FOR NEXT WEEKEND INTO EARLY NEXT
WEEK WITH INCREASING SPREAD IN THE SOLUTIONS ACROSS SOUTHERN
CALIFORNIA FOR SUNDAY AND MONDAY VERSUS SATURDAY.
