AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
905 PM PST MON FEB 17 2014

.SYNOPSIS...
A DEEPENING MARINE LAYER AND ONSHORE FLOW WILL ALLOW LOW CLOUDS AND
PATCHY FOG TO SPREAD INLAND INTO THE VALLEYS TONIGHT...AND AGAIN
TUESDAY NIGHT. DAYTIME TEMPERATURES WILL DECREASE BY ABOUT FIVE
DEGREES FOR TUESDAY AND WEDNESDAY...MAINLY WEST OF THE MOUNTAINS.
OFFSHORE FLOW WILL BRING STRONG AND GUSTY WINDS NORTHEAST WINDS ON
THURSDAY...MAINLY THROUGH AND BELOW PASSES AND CANYONS.
OTHERWISE...DRY AND WARM FOR THURSDAY THROUGH NEXT MONDAY.

&&

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

THE AFTERNOON NKX SOUNDING AND RECENT AIRCRAFT REPORT SHOW THE
MARINE LAYER ABOUT 2000 FT DEEP THIS EVENING. SFC PRESSURE GRADIENTS
ARE ONSHORE WITH +6.1 MB SAN-DAG AND +6.9 MB SAN-IPL. THE ONSHORE
GRADIENTS WITH WEST WINDS ALOFT ARE BRINGING BREEZY CONDITIONS TO
SOME PARTS OF THE MTNS AND ADJACENT DESERT AREAS...WITH THE WINDY
LOCATIONS REPORTING WIND GUSTS 25-35 MPH.

HIGH-ZONAL WESTERLY FLOW ALOFT WILL CONTINUE THROUGH TUE WITH
ONSHORE PRESSURE GRADIENTS AT THE SFC...AND THE MARINE LAYER WILL
CONTINUE TO GRADUALLY DEEPEN. THIS WILL ALLOW LOW CLOUDS AND FOG TO
SPREAD INLAND TO THE COASTAL SLOPES TONIGHT AND TUE NIGHT. PATCHY
DENSE FOG IS LIKELY AT HIGHER ELEVATIONS WHERE TERRAIN AND CLOUDS
INTERSECT. DAYTIME TEMPS WILL DECREASE BY ABOUT 5 DEGREES FOR TUE
AND WED...MAINLY WEST OF THE MTNS. A SHORTWAVE TROUGH MOVING INLAND
TO THE NORTH WED AND THU WILL BRING A PERIOD OF STRONGER NW WINDS
ALOFT WED MORNING...WITH A CORRESPONDING INCREASE IN THE WINDS
ACROSS THE MTNS AND ON ADJACENT DESERT SLOPES. WIND GUSTS AROUND 40
MPH WILL BE POSSIBLE AT THAT TIME.

THE FLOW WILL TURN OFFSHORE WED NIGHT/THU MORNING AS THE TROUGH
MOVES EWD ACROSS THE ROCKIES AND A SFC HIGH MOVES INTO THE GREAT
BASIN. STRONG AND GUSTY NE WINDS...MAINLY IN AND BELOW CANYONS AND
PASSES...WILL PEAK LATE WED NIGHT INTO EARLY THU MORNING WITH WIND
GUSTS 60 MPH OR MORE POSSIBLE. CURRENT INDICATIONS ARE THAT THIS
PATTERN WILL FAVOR THE INLAND EMPIRE BELOW THE CAJON PASS...AND THE
SANTA ANA MTNS WHERE THE STRONGEST WINDS ARE EXPECTED. THE OFFSHORE
FLOW WILL ALSO BRING DRIER AND WARMER CONDITIONS...WITH DAYTIME
TEMPS CLIMBING BACK INTO THE UPPER 70S AT SOME INLAND VALLEY
LOCATIONS.

FOR FRI THROUGH MON...CONTINUED WARM AND DRY UNDER WEAK CYCLONIC
FLOW ALOFT WITH WEAK OFFSHORE FLOW AT THE SFC. DAYTIME TEMPS ARE
EXPECTED TO BE 5 TO 10 DEGREES ABOVE SEASONAL AVERAGES IN MOST
AREAS. THE MARINE LAYER WILL BE SHALLOW ENOUGH TO LIMIT ANY NIGHT
AND MORNING LOW CLOUDS TO THE COASTAL AREAS.

&&

.AVIATION...
180435Z...COAST/VALLEYS...STRATUS WITH BASES 1100-1600 FT MSL WILL
CONTINUE TO SPREAD 30-40SM INLAND TONIGHT...POSSIBLY REACHING KONT
BETWEEN 10-12Z. AREAS OF 2-4SM VSBY IN BR/HZ DEVELOPING IN THE
INLAND VALLEYS 10-16Z. STRATUS CLEARING TO THE COAST
17-20Z...RETURNING TO THE COASTAL AIRPORTS 00-03Z WITH BASES NEAR
1500 FT MSL. OTHERWISE SCT-BKN CLOUDS AOA 20000 FT MSL AND
UNRESTRICTED VSBY THROUGH TUE NIGHT.

MTNS/DESERTS...SCT-BKN CLOUDS AOA 20000 FT MSL AND UNRESTRICTED VSBY
THROUGH TUE NIGHT.

&&

.FIRE WEATHER...
WITH THE OFFSHORE FLOW RETURNING LATE WED NIGHT...HUMIDITIES WILL
LOWER OVER MOST AREAS AGAIN THU-SAT. RH VALUES WILL BE IN THE TEENS
OVER MOST INLAND VALLEYS...LOWER MOUNTAIN SLOPES...AND THE DESERTS.
LOCALLY STRONG GUSTY NORTHEAST WINDS WILL MAINLY OCCUR LATE WED
NIGHT AND THU MORNING...SO IT IS UNLIKELY WE WILL HAVE PROLONGED
OVERLAP BETWEEN WIND GUSTS OVER 35 MPH AND RH VALUES UNDER 15
PERCENT DUE TO WIND SPEEDS BECOMING LIGHTER AS THE RH VALUES REACH
THEIR AFTERNOON MINIMUMS. THE MODERATELY LOW HUMIDITY WILL CONTINUE
FRI/SAT...BUT WINDS WILL BE LIGHTER...BUT STILL FROM THE NORTHEAST.
FOR NOW...WE DO NOT PLAN ON ANY FIRE WEATHER WATCH.

.SKYWARN...
SKYWARN ACTIVATION IS NOT REQUESTED. HOWEVER WEATHER SPOTTERS ARE
ENCOURAGED TO REPORT SIGNIFICANT WEATHER CONDITIONS.
