000 FXUS66 KSGX 052143 AFDSGX AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN DIEGO CA 200 PM PST SUN FEB 5 2012 .SYNOPSIS... HIGH PRESSURE ALOFT ALONG THE WEST COAST AND SURFACE HIGH PRESSURE OVER THE GREAT BASIN WILL BRING FAIR DRY WEATHER THROUGH MONDAY WITH GUSTY NORTHEAST WINDS NEAR THE COASTAL FOOTHILLS AT TIMES. PATCHY NIGHT AND MORNING LOW CLOUDS AND FOG MAY RETURN NEAR THE COAST ON MONDAY. A PACIFIC LOW PRESSURE SYSTEM IS EXPECTED TO TRACK JUST OFF THE COAST OF SOUTHERN CALIFORNIA TUESDAY INTO EARLY WEDNESDAY...WITH BEST CHANCES OF PRECIPITATION OVER THE COASTAL WATERS AND SOUTHWEST PORTIONS OF THE FORECAST AREA. DRY AND WARMER WITH OFFSHORE FLOW AND GUSTY NORTHEAST WINDS FOR THURSDAY INTO NEXT WEEKEND. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... SKIES WERE MOSTLY CLEAR THIS AFTERNOON WITH JUST A FEW HIGH CLOUDS BEGINNING TO MOVE IN FROM THE WEST. OFFSHORE SURFACE PRESSURE GRADIENTS ARE WEAKENING WITH ABOUT -3 MB SAN-DAG AND -1 MB SAN-IPL. LOCAL GUSTY NORTHEAST WINDS ARE EXPECTED TO CONTINUE INTO MONDAY AFTERNOON...BUT WILL REMAIN BELOW ADVISORY CRITERIA. FAIR AND DRY WITH MINOR COOLING WILL TAKE PLACE ON MONDAY AS THE UPPER LEVEL RIDGE BEGINS TO FLATTEN AND A LARGE TROUGH OF LOW PRESSURE INCHES TOWARDS THE WEST COAST AND OFFSHORE FLOW WEAKENS. VERY PATCHY LOW CLOUDS AND FOG MAY RETURN TO THE COASTAL AREAS BY EARLY MONDAY MORNING. MORE WIDESPREAD LOW CLOUDS AND FOG WILL MOVE INTO THE COASTAL AREAS MONDAY AFTERNOON...SPREADING INLAND AS THE MARINE LAYER DEEPENS MONDAY NIGHT INTO TUESDAY. FOR TUESDAY INTO WEDNESDAY...A SHORT WAVE TROUGH WILL MOVE TOWARDS THE CENTRAL CALIFORNIA COAST. A CLOSED LOW FORMING IN THE BASE OF THE TROUGH DROPS SOUTH OFF THE COAST OF SOUTHERN CALIFORNIA BY TUESDAY EVENING...EVENTUALLY TRACKING EAST ACROSS BAJA CALIFORNIA ON WEDNESDAY. 12Z MODEL RUNS ARE STILL INCONSISTENT WITH THE TRACK OF THE LOW...THOUGH THE GFS HAS TRENDED TOWARDS THE EC SOLUTION...KEEPING THE LOW FURTHER WEST AND SOUTH OF THE AREA. THIS TRACK WOULD KEEP THE BULK OF THE PRECIPITATION OVER THE COASTAL WATERS WITH SOME PRECIPITATION EXTENDING LOCALLY INLAND INTO SOUTHERN CALIFORNIA. GIVEN THIS TRACK...RAINFALL AMOUNTS WILL GENERALLY RANGE FROM ONE-TENTH TO ONE-QUARTER INCH FROM THE COAST INLAND TO THE MOUNTAINS FOR LATE TUESDAY THROUGH EARLY WEDNESDAY WITH LOCALLY HIGHER AMOUNTS IN THE SOUTHWEST PORTIONS OF THE FORECAST AREA. A TRACK A LITTLE FARTHER EAST COULD RESULT IN GREATER PRECIPITATION AMOUNTS. THE SNOW LEVEL WILL GENERALLY BE 5500 TO 6000 FEET. BASED ON THE CURRENT FORECAST TRACK SNOWFALL WILL GENERALLY BE LESS THAN ONE INCH WITH LOCAL AMOUNTS AROUND TWO INCHES IN THE SAN BERNARDINO MOUNTAINS. A 20-30 KT LOW-LEVEL JET AHEAD OF THE LOW MAY GENERATE LOCAL GUSTY SOUTH WINDS ALONG THE COAST AND IN THE MOUNTAINS AND DESERTS OF SAN BERNARDINO COUNTY. AS THE LOW TRACKS ACROSS THE BAJA PENINSULA...HIGH PRESSURE ALOFT WILL REBUILD ALONG THE WEST COAST FOR THURSDAY AND FRIDAY. THIS WILL BRING A WARMING TREND FOR SOUTHWEST CALIFORNIA WITH SURFACE HIGH PRESSURE IN THE GREAT BASIN BRINGING GUSTY NORTHEAST WINDS NEAR THE COASTAL FOOTHILLS AT TIMES. TOWARD THE LATTER PART ON NEXT WEEKEND...ANOTHER LOW PRESSURE SYSTEM COULD MOVE THROUGH SOUTHERN CALIFORNIA. && .AVIATION... 052041Z...VFR CONDS WITH FEW CLDS AOA FL180 THROUGH ABOUT 06/0600 UTC. AFTER 06/0600 UTC...FOG/STRATUS WILL BE POSSIBLE ALONG COASTAL AREAS...INCLUDING KSAN KCRQ AND KSNA...WITH BASES 300-600 FT MSL AND AREAS OF VIS 1-3SM BR AND LOCAL VIS AOB 3/4SM BR/FG. CONFIDENCE LOW IN COVERAGE AND TIMING OF FOG/STRATUS. IF FOG/STRATUS DOES FORM...IT SHOULD CLEAR OUT BY 06/1600 UTC. STRATUS APPEARS TO BE MORE LIKELY MONDAY NIGHT IN ADDITION TO MORE HIGH CLDS. && .MARINE... A STORMY PATTERN WILL BE DEVELOPING OVER THE EASTERN NORTH PACIFIC THIS WEEK SENDING A SERIES OF LARGER WESTERLY SWELLS TOWARD THE CALIFORNIA COAST. SURF AND SWELL WILL BE INCREASING BY TUESDAY NIGHT...AND CONTINUE INTO NEXT WEEKEND. PERIODS OF HIGH SURF AND DANGEROUS RIP CURRENTS ARE LIKELY...ALONG WITH SEAS ABOVE TEN FEET IN THE COASTAL WATERS. && .SGX WATCHES/WARNINGS/ADVISORIES... CA...NONE.
