AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
135 PM PST SAT NOV 12 2011
.SYNOPSIS...
UPPER LEVEL LOW OFF THE SOUTHERN CALIFORNIA COAST WILL CONTINUE TO
TRACK SOUTHEAST OFFSHORE...SPREADING PERIODS OF MODERATE TO HEAVY
RAIN ACROSS SOUTHERN CALIFORNIA THROUGH TONIGHT. ISOLATED
THUNDERSTORMS WILL BE POSSIBLE AS WELL...ESPECIALLY OVER THE COASTAL
WATERS AND PORTIONS OF SAN DIEGO AND ORANGE COUNTIES. THE STORM
WILL THEN MAKE LANDFALL ON SUNDAY OVER NORTHWEST MEXICO...PULLING
ANY FURTHER SHOWER THREAT AWAY FROM THE AREA BY THE AFTERNOON. FAIR
AND MILD WEATHER WILL RETURN NEXT WEEK UNDER DRY NORTHWEST FLOW
ALOFT AND BUILDING HIGH PRESSURE.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
WATER VAPOR IMAGERY CONTINUES TO SHOW A POTENT UPPER LEVEL LOW NEAR
30.6 NORTH AND 122 WEST SLOW MOVING EAST SOUTHEASTWARD THIS
AFTERNOON...AS A PRETTY DECENT VORTICITY MAX WRAPS AROUND THE BACK
SIDE OF THE LOW. THERE IS ALSO PLENTY OF UPPER LEVEL JET SUPPORT
WITH THIS SYSTEM...AS IT TAKES AIM AT NORTHERN BAJA. AS A
RESULT...THIS PLACES SOUTHERN CALIFORNIA IN THE PERFECT LOCATION OF
DIFLUENT FLOW ALOFT TO ENHANCE THE SECOND AND STRONGER BAND OF
PRECIPITATION. IN FACT...CURRENT RADAR IMAGERY SHOWS A WIDE SWATH
OF LIGHT AND MODERATE RAIN SPREADING ACROSS THE COASTAL WATERS AND
SAN DIEGO COUNTY THIS AFTERNOON...WITH HEAVIER SHOWERS EMBEDDED
WITHIN THIS AREA. THERE HAS EVEN BEEN A FEW LIGHTNING STRIKES OFF
THE COAST...AND MODELS SHOW SOME DECENT LIFT INDICES AND CAPE VALUES
MOVING ACROSS THE CALIFORNIA AND MEXICO BORDER THIS EVENING.
THEREFORE...IT WILL BE A SOGGY AFTERNOON AND EVENING FOR MUCH OF THE
AREAS...WITH PERIODS OF MODERATE TO HEAVY RAIN AS WELL AS ISOLATED
THUNDERSTORMS. THE SLOW MOVEMENT AND TRACK OF THE STORM...EXTREME
SOUTHERN AREAS WILL LIKELY BE THE HARDEST HIT...WITH ONLY SCATTERED
SHOWERS AT BEST MAKING IT UP INTO THE SAN BERNARDINO MOUNTAINS. AT
THIS TIME...RAINFALL TOTALS ARE STILL RANGING BETWEEN A TENTH AND
ABOUT TWO THIRDS OF AN INCH...BUT COULD EXCEED AN INCH TO AN INCH IN
A HALF LATER THIS EVENING ACROSS PORTIONS OF SAN DIEGO COUNTY.
THEREFORE...IF PERIODS OF MODERATE AND HEAVY RAIN CONTINUE TO FALL
IN THIS AREA...FOR AN URBAN AND SMALL STREAM FLOOD ADVISORY MAY BE
NEEDED. WILL CONTINUE TO MONITOR OVER THE NEXT FEW HOURS. THINGS
WILL TURN MORE SHOWERS LATE TONIGHT AND ON SUNDAY THOUGH...AS DRIER
NORTHWESTERLY FLOW STARTS TO FILTER INTO THE REGION AS THIS UPPER
LEVEL LOW MOVES INTO ACROSS BAJA AND NORTHERN MEXICO.
THEREFORE...EXPECT THE PRECIPITATION CHANCE TO DECREASE THROUGH THE
DAY.
A FLAT RIDGE OF HIGH PRESSURE WILL THEN DEVELOP OVER THE WEST FOR
MUCH OF THE WORK WEEK. EXPECT DRIER CONDITIONS TO PREVAIL...WITH
TEMPERATURES RETURNING TO NORMAL RANGES. HOWEVER...MODELS ARE
STARTING TO HINT AT ANOTHER TROUGH DEVELOPING ALONG THE WEST COAST
FOR NEXT WEEKEND. ALTHOUGH IT IS STILL TO EARLY TO TELL...MORE
UNSETTLED AND COOLER WEATHER MAY RETURN.
