AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
125 PM PDT SUN MAR 22 2015

.SYNOPSIS...
A TROUGH OF LOW PRESSURE OFF THE COAST WILL MOVE INLAND TONIGHT
AND MONDAY BRINGING COOLING...GUSTY WESTERLY WINDS ACROSS THE
MOUNTAINS AND DESERTS...A DEEPER MARINE LAYER WITH EXTENSIVE LOW
CLOUDS...AND LOCAL FOG AND DRIZZLE WEST OF THE MOUNTAINS. FOR
TUESDAY AND WEDNESDAY...SLIGHTLY WARMER WITH WEAKER WESTERLY WINDS.
MUCH WARMER AND VERY DRY THURSDAY INTO NEXT WEEKEND AS STRONG HIGH
PRESSURE BUILDS ALOFT AND GUSTY OFFSHORE WINDS DEVELOP.

&&

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

MARINE STRATUS EXTENDED WELL INTO THE VALLEYS EARLY THIS MORNING...
AND WAS SLOW TO CLEAR PORTIONS OF THE INLAND EMPIRE AND O.C. AT
MIDDAY...THICKER CIRRUS CLOUDS STILL COVERED PORTIONS OF THE LOWER
DESERTS AND EXTENDED ALONG THE CENTRAL CA COAST. ELSEWHERE...
AREAS OF MARINE CLOUDS COVERED PORTIONS OF THE COASTAL WATERS.
SURFACE PRESSURE GRADIENTS OF 4-5 MBS ONSHORE WERE FUELING WESTERLY
WINDS OF 15-20 MPH...WITH LOCAL GUSTS OF 25-35 MPH THROUGH THE WIND-
PRONE PASSES AND CANYONS.

LOW CLOUDS WILL RETURN RAPIDLY TO COASTAL AREAS LATER TODAY AND THIS
EVENING DUE TO AN APPROACHING TROUGH. THE MARINE CLOUDS WILL EXTEND
ALL THE WAY TO THE LOWER COASTAL SLOPES BY MORNING...POSSIBLY
LEAKING SOME PATCHY DRIZZLE AT TIMES INTO MON MORNING. ONCE THE
CLOUDS BURN AWAY...FAIR AND SEASONAL MARCH WEATHER WILL PREVAIL...
WITH GUSTY WESTERLY WINDS ACROSS WIND-PRONE MTN/DESERT AREAS...
DECREASING ON TUE.

AFTER THE TROUGH PASSES MON...RECENT MODEL RUNS SHOW LITTLE
RECOVERY IN HEIGHTS/THICKNESS TUE/WED...SO ONLY SLIGHT WARMING IS
EXPECTED...EXCEPT OVER NORTHERN PORTIONS OF THE CWA ON WED...WHERE
SFC WINDS ARE FORECAST TO TURN OFFSHORE FIRST. MODERATE NE FLOW ON
WED SHOULD HELP TO LIFT MAX TEMPS OVER THE INLAND EMPIRE AND
PORTIONS OF ORANGE COUNTY WELL INTO THE 80S BY AFTERNOON.

BY THU...HEIGHTS/THICKNESS WILL JUMP ACROSS THE STATE AS ANOTHER
STRONG RIDGE BUILDS NE OFF THE PACIFIC. ALSO...SFC WINDS WILL
INCREASE OUT OF THE NE AND BECOME GUSTY THROUGH AND BELOW THE PASSES
AND CANYONS...AND ALONG THE COASTAL FOOTHILLS. THE OFFSHORE WINDS
WILL CREATE VERY LOW RH ONCE AGAIN...AS THE MARINE LAYER IS DRIVEN
BACK OFFSHORE. STRONG MARCH SUN WILL RAPIDLY HEAT THE DRY AIR AS
DOWNSLOPING WINDS AUGMENT THE WARMING. THIS WILL DRIVE MAX TEMPS
WELL ABOVE AVERAGE THU THROUGH SAT AND WILL LIKELY MEAN MORE RECORD
TEMPERATURES.

HIGHEST MODEL GUIDANCE WAS USED FOR FORECAST HIGH/LOW TEMPERATURES
DURING THE HEATWAVE DUE TO THE ANOMALOUS HIGH PRESSURE AREA ALOFT
AND CONTINUED ABOVE NORMAL SEA SURFACE TEMPERATURES.

THE RIDGE IS FORECAST TO WEAKEN AND MOVE EAST ON SUNDAY...WITH
COOLER WEATHER EXPECTED THEN. THE 12Z RUNS OF THE EC/GFS EVEN BOTH
SHOW A COMPACT LOW DRIVING ACROSS THE STATE FROM THE WEST ON MON.
THIS FEATURE SHOULD HELP TO ACCELERATE THE ONSHORE FLOW AND A RETURN
OF THE MARINE LAYER WEST OF THE MTS THEN.

&&

.AVIATION...
222015Z...COAST/VALLEYS...STRATUS WILL REDEVELOP LATE THIS
AFTERNOON/EARLY THIS EVENING...WITH BASES MOSTLY 1700-2500 FT MSL
AND TOPS TO 3000 FT MSL...BECOMING 3500-4000 FT MSL AFTER 08Z. MOST
COASTAL AIRPORTS...INCLUDING KSAN...KCRQ AND KSNA SHOULD HAVE ONSET
OF BKN/OVC STRATUS BETWEEN 01Z AND 03Z WITH VALLEY LOCATIONS...
INCLUDING KONT...BETWEEN 04Z AND 07Z. HIGHER TERRAIN WILL BE
OBSCURED... BUT BELOW THE CLOUD DECK...MOST VIS WILL BE 5+ MILES.
CLEARING WILL OCCUR IN MOST AREAS 16Z-19Z MONDAY.

THROUGH MONDAY. LOCAL SURFACE GUSTS AROUND 40-45 KT FROM THE WEST
WILL OCCUR ON THE DESERT MTN SLOPES 01Z-12Z TONIGHT.

&&

.MARINE... 100 PM...NORTHWEST WINDS GUSTING TO AROUND 25 KT WILL
OCCUR OVER THE OUTER COASTAL WATERS DURING THE LATE AFTERNOONS AND
EVENINGS MONDAY THROUGH TUESDAY. THESE WINDS WILL ALSO GENERATE
STEEP WAVES OF 5-7 FEET BRINGING TOTAL SEAS TO AROUND 8 FEET.
A SMALL CRAFT ADVISORY WILL BE ISSUED FROM MONDAY AFTERNOON THROUGH
TUESDAY EVENING IN THE OUTER COASTAL WATERS. WINDS AND SEAS WILL
SUBSIDE LATE TUESDAY NIGHT.
