AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE SAN DIEGO CA
900 PM PST SAT JAN 11 2014

.SYNOPSIS...
AREAS OF DENSE FOG WILL OCCUR OVERNIGHT INTO EARLY SUNDAY ALONG THE
COAST. OFFSHORE FLOW WILL DEVELOP LATE SUNDAY AND SUNDAY NIGHT AND
BRING STRONG GUSTY WINDS AT TIMES FROM THE NORTHEAST SUNDAY NIGHT
THROUGH THURSDAY THROUGH AND BELOW PASSES AND CANYONS AND NEAR
MOUNTAIN RIDGES. THE OFFSHORE FLOW WILL BRING VERY WARM WEATHER WEST
OF THE MOUNTAINS WITH LOW HUMIDITY MOST OF NEXT WEEK. NO
PRECIPITATION WILL OCCUR THROUGH THE END OF NEXT WEEK.

&&

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

AREAS OF DENSE FOG MOVED INTO THE IMMEDIATE COAST OF SOUTHERN SAN
DIEGO COUNTY EARLY THIS AFTERNOON AND SPREAD A FEW MILES INLAND.
SEVERAL AIRPORTS...INCLUDING LINDBERGH FIELD...IMPERIAL BEACH AND
BROWN FIELD HAVE HAD VISIBILITIES OF 1/4 MILE EARLY THIS
EVENING...THOUGH VISIBILITIES HAVE IMPROVED SOME IN THE PAST HOUR AT
SEA LEVEL LOCATIONS. THE MARINE LAYER COULD BE LIFTING JUST SLIGHTLY
SO THAT THE DENSE FOG WILL BE MOST LIKELY ON THE MESAS AND SLIGHTLY
ELEVATED COASTAL TERRAIN OVERNIGHT. FOG HAS NOT YET BEEN REPORTED IN
ORANGE COUNTY...BUT IT SHOULD START FORMING ALONG THAT COAST SOON
AND MOVE A FEW MILES INLAND. THE DENSE FOG ADVISORY WILL LAST UNTIL
9 AM SUNDAY FOR THE COASTAL AREAS...BASICALLY WITHIN 10 MILES OF THE
COAST...OF ORANGE/SAN DIEGO COUNTIES.

THE MAIN EVENT NEXT WEEK WILL BE THE PERSISTENT OFFSHORE FLOW.
CURRENTLY...SEVERAL WEAK SHORTWAVES WERE MOVING THROUGH
NORTHERN/CENTRAL CALIFORNIA AND WILL MOVE SE OVER SO-CAL SUNDAY. THE
MOST SIGNIFICANT OF THE SHORTWAVES WILL MOVE THROUGH SUNDAY
AFTERNOON AND WILL BE FOLLOWED BY A STRONG UPPER RIDGE OVER THE
CALIFORNIA COAST AND A STRENGTHENING SURFACE HIGH OVER NORTHERN
NEVADA. THERE WLLL BE MODERATE COLD AIR ADVECTION IN THE 850-700 MB
LAYER WITH SOME MTN WAVE POTENTIAL...THOUGH THERE IS STILL NO
NOTABLE INVERSION OR STRONG STABLE LAYER IN THE LOCAL WRF SOUNDINGS
FOR MON/TUE. THE OFFSHORE GRADIENTS WILL BE ABOUT 14-15 MB OFFSHORE
FROM CENTRAL NEVADA TO SAN DIEGO MONDAY MORNING AND POSSIBLY AROUND
17-18 MB OFFSHORE TUESDAY MORNING. WIND GUST POTENTIAL WILL DEPEND
ON LOCATION...BUT ISOLATED LOCATIONS COULD HAVE GUSTS WELL OVER 60
MPH AT PLACES LIKE SILL HILL OR FREMONT CANYON...ESPECIALLY TUE
MORNING...WITH MOST OTHER AREAS NEAR RIDGES AND THROUGH/BELOW PASSES
AND CANYONS HAVING PEAK WINDS IN THE 50-55 MPH RANGE. LOOKS LIKE WE
WILL NEED A HIGH WIND WATCH FOR THE MOUNTAINS AND THE INLAND
EMPIRE...WITH MOST AREAS HAVING THE WATCH FROM LATE SUNDAY NIGHT
THROUGH TUESDAY...EXCEPT SAN DIEGO COUNTY MTNS WILL WAIT UNTIL
MONDAY NIGHT WHEN THE FLOW BECOMES A LITTLE MORE EASTERLY. IT IS
POSSIBLE THAT THE EVENT WILL LAST INTO WED.

IT WILL BE QUITE WARM MOST OF THE WEEK...WITH WIDESPREAD 80S WEST OF
THE MTNS TUE/WED. SOME DAILY RECORD HIGHS COULD BE SET. HUMIDITIES
WILL BE QUITE LOW GIVEN THE STRONG SURFACE OFFSHORE GRADIENTS AND
DRY SOURCE OF THE AIR MASS MOST OF NEXT WEEK. THE UPPER RIDGE DOES
APPEAR TO WEAKEN SOMEWHAT NEXT WEEKEND AS THE LONG WAVE TROUGH MOVES
FROM THE NORTH-CENTRAL PACIFIC TOWARDS INTO THE PACIFIC NW...THOUGH
MOST MODEL RUNS KEEP HEIGHTS RATHER HIGH OVER CENTRAL/SOUTHERN
CALIFORNIA. HOWEVER...THIS PATTERN WILL AT LEAST STOP THE BLOCKING
RIDGE SO THAT IF A DEEPER TROUGH WERE TO APPROACH...IT COULD BRING
PRECIPITATION IN THE WEEK OF JAN 19-25...THOUGH IT IS STILL
SPECULATIVE NOW.

&&

.AVIATION...
120400Z...COAST/VALLEYS...THROUGH 12/16Z...BKN-OVC STRATUS/FOG WILL
CONTINUE TO FORM ALONG THE BEACHES SPREADING NORTH AND 5-10 SM
INLAND...WITH AREAS OF VIS 3-5SM...LOCALLY VIS AOB 1/2SM IN FOG.
EXPECT BASES AROUND 300-600 FT MSL WITH TOPS AROUND 800 FT MSL.
AFTER 12/16Z...SCT CLOUDS AOA 20000 FT MSL THROUGH THE AFTERNOON.
LLWS WILL BECOME A FACTOR AFTER 12/18Z AT KCRQ...KSNA...KONT...AND
POSSIBLY KSAN AS WELL BEFORE OFFSHORE WINDS SURFACE OVERNIGHT INTO
MONDAY.

MTNS/DESERTS...UNRESTRICTED VIS AND SCT CLDS AOA 20000 FT MSL
THROUGH SUNDAY MORNING.

&&

.MARINE...
PATCHY DENSE FOG IS LIKELY THROUGH SUNDAY MORNING OVER THE COASTAL
WATERS DUE TO A SHALLOW MARINE LAYER.

A COUPLE 4-5 FOOT NORTHWEST SWELLS WILL CONTINUE OVER THE NEXT FEW
DAYS. DUE TO THE STEEP ANGLE OF THE SWELLS...AND PERIODS OF ONLY
14-15 SECONDS...NOT AS MUCH ENERGY FROM THE SWELLS WILL MAKE IT INTO
OUR BEACHES. THEREFORE...SETS WILL LIKELY ONLY REACH AROUND 5 FEET
WITH STRONG RIP CURRENTS.

&&

.FIRE WEATHER...
A RED FLAG WARNING IS IN EFFECT FOR ALL MOUNTAINS AND ADJACENT
VALLEY AREAS...AND INLAND ORANGE COUNTY FROM LATE SUNDAY NIGHT
THROUGH WEDNESDAY.

THERE WILL MOSTLY BE NO FIRE WEATHER ISSUES THROUGH
SUNDAY...ALTHOUGH WESTERLY WINDS WILL BE LOCALLY GUSTY
OVERNIGHT...TO AROUND 35-40 MPH...OVER THE RIDGES AND INTO THE
DESERTS...ESPECIALLY IN SAN BERNARDINO COUNTY.

FROM LATE SUNDAY THROUGH FRIDAY...HIGH PRESSURE ALOFT OVER THE WEST
COAST AND SURFACE HIGH PRESSURE OVER THE GREAT BASIN WILL BRING AN
EXTENDED WARM AND DRY PERIOD WITH VERY LOW RH AND OFFSHORE FLOW.
AREAS OF NORTHEAST WINDS OF 20 TO 30 MPH WITH GUSTS OF 45 TO 55 MPH
WILL DEVELOP NEAR THE COASTAL FOOTHILLS SUN NIGHT THROUGH WED.
ISOLATED WIND GUSTS OF 60 MPH OR MORE WILL OCCUR MON/TUE IN THE
OFFSHORE WIND PRONE LOCATIONS IN THE SANTA ANA MOUNTAINS...BELOW
CUYAMACA PEAK IN SAN DIEGO COUNTY...AND LOCALLY BELOW THE CAJON AND
BANNING PASS AREAS. THE WINDS WILL WEAKEN WED AFTERNOON THROUGH
THU...BUT THE LOW RH WILL CONTINUE INTO FRI.

ENCOURAGED TO REPORT SIGNIFICANT WEATHER CONDITIONS.
