AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 PM PDT MON MAY 19 2008

.SYNOPSIS...
MUCH COOLER WEATHER IS EXPECTED THE REST OF THIS WEEK AS THE MARINE
LAYER DEEPENS AND ONSHORE FLOW INCREASES. GUSTY WINDS WILL DEVELOP
OVER THE MOUNTAINS AND DESERTS TUESDAY AFTERNOON THROUGH WEDNESDAY
AND A FIRE WEATHER WATCH HAS BEEN ISSUED FOR THE DESERT AREAS DUE TO
THE DRY AND WINDY CONDITIONS. A LOW PRESSURE SYSTEM WILL CAUSE A
SLIGHT CHANCE OF SHOWERS OR THUNDERSTORMS LATE THURSDAY THROUGH
FRIDAY. CLOUDY...COOL AND UNSETTLED WEATHER MAY CONTINUE THROUGH
MEMORIAL DAY WEEKEND AS THE LOW PRESSURE SYSTEM REMAINS OVER THE
AREA.

&&

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

.SHORT TERM...
THE UPPER RIDGE AXIS WHICH HAS CONTROLLED OUR WEATHER SINCE LATE
LAST WEEK WILL FINALLY BREAK DOWN ON TUESDAY AND USHER IN A
SIGNIFICANT COOLING TREND. HIGH TEMPERATURES ON TUESDAY SHOULD BE
10-15 DEGREES COOLER WEST OF THE MOUNTAINS...HOWEVER THE LOWER
DESERTS WILL LIKELY ENDURE ANOTHER DAY OF HOT WEATHER BEFORE RELIEF
IS FELT. A SHALLOW MARINE LAYER WILL CAUSE PATCHY DENSE FOG ALONG
THE COAST AND OVER THE COASTAL MESAS OVERNIGHT AND EARLY IN THE
MORNING...BUT CLOUDS SHOULD CLEAR TO THE BEACHES BY MID MORNING.
GUSTY WINDS WILL DEVELOP IN THE MOUNTAINS AND DESERT LATE TUESDAY
THROUGH WEDNESDAY AND THE MARINE LAYER WILL DEEPEN TO BETWEEN 2000
AND 3000 FT DEEP AS ONSHORE PRESSURE GRADIENTS STRENGTHEN AND A
TROUGH OF LOW PRESSURE MOVES TOWARDS THE AREA. WINDS COULD REACH
ADVISORY STRENGTH WITH LOCAL GUSTS IN EXCESS OF 45 MPH IN THE UPPER
DESERTS ON WEDNESDAY.

A HIGHLY AMPLIFIED AND COMPLEX UPPER-LEVEL PATTERN BEGINS TO TAKE
SHAPE BY WEDNESDAY AFTERNOON AS A DEEP UPPER TROUGH DIGS OVER THE
GREAT BASIN. BY THURSDAY...THE GFS PUTS SOUTHERN CALIFORNIA IN THE
LEFT FRONT QUADRANT OF A 120 KT JET AND PLACES THE CENTER OF THE
UPPER LOW OVER THE COLORADO RIVER VALLEY. THE ECMWF IS SLIGHTLY
WEAKER WITH THIS SYSTEM INITIALLY BUT PLACES THE JET AND UPPER LOW
IN THE SAME GENERAL AREA. THIS SHOULD AT THE VERY LEAST DEEPEN THE
MARINE LAYER AND CONTINUE THE COOLING TREND...BUT COULD JUST AS
EASILY RESULT IN A FEW LIGHT SHOWERS.

.LONG TERM...
BIG DIFFERENCES AMONG THE MODELS REGARDING THE EVOLUTION OF THE
UPPER LEVEL PATTERN AFTER THURSDAY. THE WRF AND ECMWF DEVELOP
ANOTHER UPPER LOW UPSTREAM AND BRING IT OVER SOUTHERN CALIFORNIA BY
LATE FRIDAY...WHILE THE GFS IS SLOWER AND FURTHER NORTH WITH THIS
FEATURE. INSTABILITY PARAMETERS ARE NOT VERY IMPRESSIVE AT THIS
POINT BUT GIVEN THE CLOSE PROXIMITY OF THE JET AND UPPER LOW...AND
COLDER TEMPS ALOFT...WENT AHEAD AND ADDED A SLIGHT CHANCES OF
THUNDERSTORMS FOR THURSDAY AFTERNOON THROUGH FRIDAY. WITH ALL MODELS
INDICATING SOME FORM OF A CLOSED LOW LINGERING NEAR THE REGION
THROUGH THE MEMORIAL DAY WEEKEND...EXPECTED THE WEATHER TO REMAIN
COOL AND CLOUDY WITH A DEEP MARINE LAYER EXTENDING INTO THE COASTAL
SLOPES.

&&

.FIRE WEATHER...
CRITICAL FIRE WEATHER PATTERN POSSIBLE TUESDAY AFTERNOON THROUGH
WEDNESDAY DUE TO INCREASING SOUTHWEST WINDS ACROSS MOUNTAINS/DESERTS
AND A LINGERING DRY AIR MASS. IT APPEARS 6 HOUR DURATIONS OF WINDS
GUSTING OVER 35 MPH WHILE RELATIVE HUMIDITY IS AT OR BELOW 15
PERCENT WILL BE MET TUESDAY AFTERNOON AND EVENING OVER THE RIDGES
AND DESERT SLOPES OF THE SAN BERNARDINO AND CLEVELAND NATIONAL
FORESTS...AS WELL AS THE APPLE/LUCERNE/YUCCA/MORONGO VALLEYS OF SAN
BERNARDINO COUNTY...THE COACHELLA VALLEY IN RIVERSIDE COUNTY...AND
THE ANZA BORREGO DESERT AREAS OF SAN DIEGO COUNTY. RELATIVE HUMIDITY
WILL BE POOR IN THESE AREAS TUESDAY NIGHT/WEDNESDAY MORNING...IN THE
20 TO 30 PERCENT RANGE...AND WINDS WILL STILL BE GUSTING OVER 35 MPH.

&&

.AVIATION...
200230Z...MDCRS SOUNDINGS SHOW THE MARINE LAYER DEPTH RANGING
BETWEEN 600 AND 1K FT AT 01Z. MARINE STRATUS/FOG SHOULD BEGIN
AFFECTING THE COASTAL AIRPORTS BY 08Z. INCREASING ONSHORE GRADIENTS
WILL PULL IT INTO SOME WESTERN VALLEYS AS WELL BY MORNING. THE
MARINE LAYER DEPTH SHOULD REMAIN AOB 1.5K FT...SO AREAS OF IFR/LIFR
CIGS/VIS WILL LIKELY DEVELOP AND MAY PERSIST THROUGH 15-16Z TUE TIME
FRAME IN SOME AREAS. ON THE MESAS...OR NEAR THE LEADING EDGE OF THE
STRATUS LAYER...LOCAL DENSE FOG WILL BE POSSIBLE. STRATUS/FOG
EXPECTED TO MIX OUT BY 18Z MOST AREAS...BUT MAY LINGER ALONG THE
IMMEDIATE COAST. HAZE WILL LIKELY LIMIT VIS TO BETWEEN 3-5SM IN SOME
VALLEYS W OF THE MOUNTAINS THROUGH MIDDAY. ABOVE THE MARINE
LAYER...A MOSTLY CLEAR SKY WITH UNRESTRICTED VISIBILITY WILL
CONTINUE THROUGH TUESDAY.

&&

.MARINE...
200230...A LONG-PERIOD SOUTH SWELL IS EXPECTED TO BEGIN MOVING INTO
THE COASTAL WATERS TUESDAY. SOUTH SWELL IS STEEP AT 170 DEGREES...SO
MOST AFFECTED AREAS WILL BE S FACING BEACHES OF NORTHERN SAN DIEGO
AND ORANGE COUNTIES. STRONG RIP CURRENTS ARE LIKELY...AND SURF COULD
BE RATHER LARGE IN ORANGE COUNTY LATE TUESDAY INTO WEDNESDAY WITH A
FEW SETS TO 8 OR 9 FEET POSSIBLE.

A LATE SPRING STORM WILL DEVELOP OVER THE SOUTHWESTERN U.S. ON WED
AND THU. STRONG ONSHORE FLOW WILL LIKELY RESULT BY WED AFTERNOON.
THE COMBINATION OF THE STRONG WIND...MODERATE S SWELL...AND A LARGE
NW WIND SWELL...WILL MAKE FOR HAZARDOUS SMALL CRAFT CONDITIONS WED
AFTERNOON INTO THU.
