AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
925 AM PDT THU APR 24 2014

.SYNOPSIS...
FAIR TODAY...WITH VARIABLE HIGH CLOUDS AND SEASONAL TEMPERATURES.
MARINE LAYER CLOUDS AND FOG RETURN TO THE COASTAL AREAS TONIGHT INTO
FRIDAY MORNING. A STRONG LOW PRESSURE TROUGH WILL MOVE ACROSS
SOUTHERN CALIFORNIA LATE FRIDAY INTO SATURDAY...BRINGING SCATTERED
SHOWERS WITH MUCH LOWER TEMPERATURES AND SOME LIGHT SNOW IN THE HIGH
MOUNTAINS. THE TROUGH WILL ALSO PRODUCE GUSTY WEST WINDS IN THE
MOUNTAINS AND DESERTS. A RIDGE OF HIGH PRESSURE BUILDING OVER THE
WEST WILL BRING MUCH WARMER WEATHER NEXT WEEK. PERIODS OF OFFSHORE
WINDS WILL BE POSSIBLE AT TIMES DURING THE MIDDLE OF NEXT WEEK.

&&

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

FAIR SKIES THIS MORNING WITH VARIABLE HIGH CLOUDS AND SMALL PATCHES
OF LOW CLOUDS OFF THE SAN DIEGO COUNTY COAST. THE MORNING SOUNDING
SHOWS LITTLE IN THE WAY OF A MARINE LAYER...WITH A VERY WEAK
INVERSION AT ABOUT 1800 FT. EXPECT TEMPERATURES THIS AFTERNOON
MOSTLY IN THE 60S AT THE COAST AND 70S TO LOW 80S ACROSS THE INLAND
VALLEYS.

LOW CLOUDS AND FOG WILL LIKELY RETURN TO THE COASTAL AREAS AND
WESTERN PORTIONS OF THE INLAND VALLEYS TONIGHT INTO FRI MORNING...AS
ONSHORE FLOW STRENGTHENS AND A COASTAL EDDY FORMS AHEAD OF A LOW
PRESSURE TROUGH APPROACHING FROM THE NW. THE LOW CLOUDS AND FOG
SHOULD BURN OFF BY LATE MORNING...BUT DAYTIME TEMPS WILL BE MOSTLY
IN THE 60S TO LOW 70S WEST OF THE MTNS.

THE DEEPENING LOW PRESSURE TROUGH WILL MOVE THROUGH SOCAL BETWEEN
FRI EVENING AND SAT MORNING. IT WILL BRING STRONG WINDS TO THE
MOUNTAINS...DESERTS AND COASTAL WATERS FRIDAY AFTERNOON AND
NIGHT...DECREASING SOMEWHAT THROUGH SATURDAY EVENING. IN THE MTNS
AND ON ADJACENT DESERT SLOPES...WIND GUSTS OF 45 TO 60 MPH ARE
LIKELY WITH OCCASIONAL GUSTS OF 75 TO 80 MPH IN THE MORE WIND-PRONE
AREAS. THE WINDS WILL BE STRONGEST FRI EVENING INTO FRI NIGHT.
BLOWING DUST AND SAND WILL BE POSSIBLE IN THE DESERTS. THE TROUGH
WILL ALSO BRING SHOWERS...MOSTLY OVER AND WEST OF THE MTNS. SHOWERS
SHOULD BEGIN MOVING IN FRI EVENING AND CONTINUE THROUGH SAT
MORNING...THEN TAPER OFF SAT AFTERNOON. MOST OF THE PRECIP IS
EXPECTED FRI NIGHT WITH TOTALS OF LESS THAN 0.25 INCH FOR MOST
LOCATIONS WEST OF THE MTNS. THE STRONG SW TO W WINDS WILL RESULT IN
STRONG OROGRAPHIC ENHANCEMENT...AND SOME AREAS ALONG THE COASTAL MTN
SLOPES COULD GET BETWEEN 0.50 AND 0.75 INCH OF RAIN. THE SNOW LEVEL
IS EXPECTED TO LOWER TO BETWEEN 5000 AND 5500 FT SAT MORNING...AND A
FEW INCHES OF SNOW COULD ACCUMULATE ABOVE 5500 FT WITH UP TO 4
INCHES POSSIBLE AT THE HIGHEST PEAKS OF THE SAN BERNARDINO AND SAN
JACINTO MTNS. THE COLD AIR MOVING IN ALOFT ON SAT MORNING COULD
RESULT IN ENOUGH INSTABILITY FOR ISOLATED TSTMS...BUT THEY WILL
LIKELY BE ISOLATED AND LIMITED TO AREAS NORTH OF SAN DIEGO COUNTY.
THE SYSTEM MOVES QUICKLY EAST ON SAT AFTERNOON...BUT TEMPS WEST OF
THE MTNS WILL REMAIN IN THE 60S.

A HIGH PRESSURE RIDGE GRADUALLY BUILDS IN FROM THE WEST NEXT WEEK
AND ANY MARINE LAYER WILL BE SHALLOW AND HAVE TROUBLE SPREADING
INLAND. SO EXPECT FAIR WEATHER WITH A WARMING TREND SUNDAY AND
MONDAY. AS THIS RIDGE OF HIGH PRESSURE AMPLIFIES ALONG THE WEST
COAST...A COLD SFC HIGH OVER THE INTER-MOUNTAIN WEST WILL BRING
PERIODS OF OFFSHORE FLOW. THIS WILL INCREASE TEMPS IN OUR REGION
TUESDAY AND WEDNESDAY. 90S WILL BE COMMON AT LOWER ELEVATIONS AND
EVEN 80S NEAR THE COAST.

&&

.AVIATION...
241500Z...COAST/VALLEYS...SCT-LOCALLY BKN CIGS 1000-1500 FT MSL ARE
POSSIBLE NEAR THE SOUTHERN SAN DIEGO COUNTY COAST THIS MORNING BUT
SHOULD REMAIN OUT OF THE COASTAL TAF SITES. OTHERWISE...MOSTLY CLEAR
SKIES WITH UNRESTRICTED VIS AND SCT CIRRUS AOA 20K FT THROUGH 00Z
THIS AFTERNOON. MVFR CIGS EXPECTED TO REFORM ALONG THE COASTAL STRIP
02Z-05Z THIS EVENING AND SPREAD INLAND OVERNIGHT. EXTENT SHOULD BE
FAR ENOUGH INLAND TO IMPACT KONT FOR A FEW HOURS EARLY FRIDAY
MORNING. EXPECT LITTLE IN THE WAY OF CLEARING OF LOW CLOUDS AT THE
COAST BEFORE MORE WIDESPREAD CLOUD COVER MOVES IN AHEAD OF THE
APPROACHING TROUGH FRIDAY AFTERNOON.

MTNS/DESERTS...SCT CLOUDS AOA 20K FT WITH UNRESTRICTED VIS THROUGH
FRIDAY MORNING.

&&

.MARINE...
NO MARINE ISSUES THROUGH MIDDAY FRIDAY.

FRI AFTERNOON THROUGH SAT...20-30 KT WINDS WILL DEVELOP OVER THE
COASTAL WATERS...ACCOMPANIED BY A STEEP WNW SWELL. WINDS COULD GUST
TO GALE FORCE BRIEFLY SAT MORNING. CONFIDENCE IS HIGH THIS WILL
GENERATE TEN FOOT OR GREATER SEAS AND CONDITIONS HAZARDOUS FOR SMALL
CRAFT DURING THIS PERIOD.

A 3-4 FT LONG-PERIOD SOUTH SWELL THIS WEEKEND MAY PRODUCE HIGH SURF
CONDITIONS WITH SETS OF 7 TO 8 FT ALONG FAVORED SOUTH-FACING BEACHES
OF ORANGE COUNTY SAT-SUN. SLIGHTLY LOWER SURF FOR SAN DIEGO COUNTY
BEACHES...HOWEVER STRONG LONGSHORE AND RIP CURRENTS ARE LIKELY.
