AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PDT FRI OCT 10 2008

.SYNOPSIS...A STRONG LOW PRESSURE TROUGH WILL BRING COLDER WEATHER
THIS WEEKEND...POSSIBLE SHOWERS...AND GUSTY MOUNTAIN AND DESERT
WINDS. THE BEST CHANCE FOR SHOWERS WILL BE TONIGHT AND EARLY
SATURDAY WITH THE PASSAGE OF THE COLD FRONT. OFFSHORE FLOW WILL
DEVELOP ON SUNDAY PRODUCING A WARMING TREND AND SANTA ANA WIND
CONDITIONS. THE STRONGEST NORTHEAST WINDS WILL OCCUR MONDAY MORNING
THROUGH AND BELOW MOUNTAIN PASSES...THEN WILL WEAKEN TUESDAY.

&&

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

THE COASTAL EDDY AND DEEP MARINE LAYER COVERED THE ENTIRE COASTAL
BASIN EARLY THIS MORNING BUT SINCE HAS BEEN ERODED IN THE LA BASIN
BY SOME DRY NORTHERLY FLOW. THIS PARTIAL CLEARING PATTERN TODAY WILL
CONTINUE FROM NORTH TO SOUTH AND PROBABLY FROM THE COAST TO INLAND
AREAS. THE DEEP UPPER TROUGH IS ON SCHEDULE TO DROP DOWN INTO SOCAL
TONIGHT. THE ALREADY STRONG WINDS WILL INCREASE TODAY IN THE UPPER
DESERT AND SPREAD SOUTHWARD THROUGH ALL THE MTNS AND DESERTS DURING
THE DAY. THAT COMBINED WITH THE LOW HUMIDITY IN THE UPPER DESERT IS
THE REASON FOR THE SHORT WINDOW RED FLAG WARNING THERE TODAY. FOR
THE STRONG WINDS TONIGHT...A LOW END WIND WARNING OR A HIGH END WIND
ADVISORY WILL BE IN EFFECT. THE COLD FRONT WILL FOLLOW THOSE
STRONGEST WINDS AND MOVE INTO MEXICO BY SUNRISE SAT. AS THE COLD
FRONT MOVES THROUGH THE RESIDUAL MARINE LAYER MOISTURE AND WHAT TINY
AMOUNT OF MOISTURE IS ALOFT...A FEW SHOWERS COULD BE SQUEEZED OUT
MOST LIKELY IN THE COASTAL MOUNTAIN SLOPES...BUT STILL REMOTELY
POSSIBLE ANYWHERE WEST OF THE MOUNTAIN CRESTS. THE BEST CHANCE OF
THIS IS BETWEEN AROUND 9 PM TONIGHT AND 9 AM SAT. THE WINDS DROP OFF
SAT AND THE BIG STORY WILL BE SIMPLY THE COOLEST WEATHER SINCE MARCH
OR SO. ON SAT NIGHT AND SUN THE FLOW GRADUALLY TURNS NORTHERLY THEN
NORTHEAST. THIS WILL DRY OUT THE AIR ALL THE WAY TO THE COAST. THE
OFFSHORE FLOW INCREASES A LOT SUN NIGHT AND MON MORNING TO ADD
STRONG WINDS TO THAT DRY AIR...TO THE TUNE OF 20 TO 40 MPH SUSTAINED
WINDS IN THE FOOTHILLS AND BELOW PASSES...WITH PEAK WINDS TOPPING 60
MPH. OBVIOUSLY THE FIRE GROWTH POTENTIAL GOES WAY UP. ALTHOUGH THIS
UPCOMING SANTA ANA EVENT WILL BE SERIOUS...IT APPEARS WEAKER IN ALL
RESPECTS TO THE OCT 2007 EVENT. WIND SPEEDS AND DURATIONS WILL BE
LESS AND TEMPS WILL BE LOWER. WINDS WILL DECREASE MON NIGHT AND THEN
ESPECIALLY TUE AFTERNOON...BUT THE HUMIDITY WILL CONTINUE VERY LOW
THROUGH WED. A WARMING TREND WILL START SUN AND CONTINUE THROUGH THU
AS HIGH PRESSURE DEVELOPS ALOFT.

&&

.AVIATION...
101600Z...MARINE LAYER DEEPEND TO AROUND 3500 FEET ALONG THE COAST
AND TO NEAR 5000 FEET OVER INLAND AREAS OVERNIGHT. MARINE LAYER
DEPTH SHOULD REMAIN NEAR 5000 FEET THROUGH TONIGHT THEN LOWER
SATURDAY AND SUNDAY. STRATUS WITH BASES BETWEEN 2500 AND 4000 FEET
MSL EXTENDS INLAND TO THE LOWER COASTAL SLOPES. EXPECT LIMITED
BREAKUP OF THE STRATUS TODAY EXCEPT A REVERSE CLEARING PATTERN COULD
BRING SCATTERED CONDITIONS TO THE COASTAL AREAS THIS AFTERNOON. THIS
AREA SHOULD FILL BACK IN THIS EVENING AFTER SUNSET. RAPID BREAKUP
SATURDAY MORNING BEHIND A COLD FRONT EXPECTED TO PASS THROUGH THE
AREA BETWEEN 12Z AND 15Z SATURDAY MORNING.

ABOVE THE MARINE LAYER...A MOSTLY CLEAR SKY WITH UNRESTRICTED
VISIBILITIES WILL CONTINUE THROUGH SATURDAY.

GUSTY WEST TO NORTHWEST WINDS ACROSS THE MOUNTAINS THIS AFTERNOON
AND TONIGHT WILL BRING SOME MOUNTAIN WAVE AND ROTOR ACTIVITY WITH
ASSOCIATED UP AND DOWN DRAFTS AND LOW LEVEL WIND SHEAR TO THE DESERT
AREAS AROUND KPSP AND KTRM. THIS COULD ALSO RESULT IN AREAS OF
BLOWING DUST AND SAND NEAR THESE AIRPORTS. HORTON

STRONG WINDS AND LOW HUMIDITIES OF 15-20 PERCENT PERSIST IN THE HIGH
DESERTS THIS MORNING. EXPECT HUMIDITIES TO FALL BELOW 15 PERCENT

40 MPH. RED FLAG WARNING REMAINS IN EFFECT.

SANTA ANA EVENT DEVELOPING SUNDAY NIGHT AND MONDAY WITH NE WINDS OF
20 TO 40 MPH IN MANY AREAS WITH GUSTS TO 50 MPH OR MORE THROUGH THE
