200 PM PST SAT FEB 2 2008
.SYNOPSIS...A POTENT...FAST MOVING WINTER STORM WILL BRING RAIN AND
MOUNTAIN SNOW LATE TONIGHT AND SUNDAY. STRONG WINDS WILL ALSO
ACCOMPANY THIS STORM. NEXT WEEK WE GET A BREAK IN THE WEATHER AS
HIGH PRESSURE BUILDS OVER THE WEST...BRINGING WARM...DRY DAYS AND
PERIODS OF OFFSHORE FLOW.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
.SHORT TERM...TONIGHT THROUGH MONDAY...
MOIST WEST TO NORTHWEST FLOW CONTINUES THROUGH THIS EVENING WITH
LIGHT PRECIPITATION FALLING ALONG COASTAL SLOPES AND FOOTHILLS FROM
UPSLOPE FLOW AND ADDITIONAL LIFTING FROM CYCLONIC CURVATURE AND
SHEAR ALOFT FROM WEAK PRECURSOR TROUGH. A 135 TO 150 KT JET HAS
NOSED INTO NW CALIFORNIA COAST THIS AFTERNOON AND THIS WILL BE THE
DRIVING MECHANISM FOR BRINGING A MUCH STRONGER SHORT WAVE SOUTHEAST
ACROSS SOUTHERN CALIFORNIA ON SUNDAY. ALL MODELS...INCLUDING
CANADIAN... UKMET...AND ECMWF...STILL IN VERY GOOD AGREEMENT ON
TIMING AND STRENGTH OF THIS SHORT WAVE TROUGH CONSEQUENTIALLY
FORECASTER CONFIDENCE IS VERY HIGH ON TIMING OF MAIN PRECIPITATION
EVENT EARLY SUNDAY MORNING THROUGH LATE SUNDAY AFTERNOON AND CURRENT
QPF AMOUNTS....SEE HYDROLOGY SECTION BELOW WHICH INCLUDES EXCERPTS
FROM EARLY MORNING FORECAST DISCUSSION. ONLY SIGNIFICANT CHANGES
MADE TO FORECAST WERE IN WIND FORECAST AND HAVE HAVE EXPANDED HIGH
WIND WATCH TO INCLUDE LOWER DESERTS. NAM MODEL SHOWS 7 TO 9 MB
PRESSURE GRADIENT WEST TO EAST ACROSS SAN DIEGO/RIVERSIDE COUNTY
MOUNTAINS FROM LATE SUNDAY MORNING THROUGH MOST OF SUNDAY NIGHT.
LOCAL WIND PROGRAM CONTINUES TO INDICATE 65-80 MPH GUSTS FOR DESERT
MOUNTAIN SLOPES AND LOWER DESERTS DURING THIS PERIOD AND LOOKING AT
THE ORIENTATION AND STRENGTH OF THE JET STREAM MOUNTAINS WAVES
TOUCHING DOWN IN THE COACHELLA VALLEY AND ANZA BORREGO DESERT LOOK
PLAUSIBLE. SMALL CRAFT ADVISORIES HAVE BEEN UPGRADED TO GALE
WARNINGS. LIKEWISE COASTS AND VALLEYS WILL BE QUITE WINDY AND WILL
LIKELY NEED TO ISSUE WIND ADVISORIES FOR SAME TIME PERIOD...PROBABLY
LATE THIS EVENING OR ON MIDNIGHT SHIFT SINCE START TIME IS STILL +12
HOURS AWAY. FOLLOWING THE SHORT WAVE TROUGH AXIS PASSAGE ON SUNDAY
NIGHT...IT CONTINUES TO BE DRIVEN SOUTHEAST AND CONSEQUENTIALLY THE
HIGH PRESSURE RIDGE AMPLIFIES ALONG 130W LONGITUDE...RESULTING IN
NORTH TO NORTHEAST FLOW DRIVING A BACK DOOR COLD FRONT ACROSS THE
MOJAVE DESERT AND INTO SOUTHWEST CALIFORNIA MONDAY MORNING. DID
INCREASE CLOUDS OVER MOUNTAINS AND DESERTS ON MONDAY BUT DID NOT
INCREASE POPS OR INCLUDE MENTION OF PRECIPITATION. BOOSTED WINDS
OVER THE SANTA ANA MOUNTAINS AND BELOW CAJON PASS FOR MONDAY
AFTERNOON AND EVENING TO REFLECT GUSTY NORTH TO NORTHEAST WINDS.
.LONG TERM...TUESDAY THROUGH NEXT SATURDAY...
COLD NORTHERLY FLOW ENDS TUESDAY MORNING AND THEN REGION UNDER
UNDER WEAK NORTHEAST TO EAST FLOW THROUGH WEDNESDAY AS SHORT WAVE
MOVING INTO PACIFIC NORTHWEST STATES DISLODGES SURFACE HIGH OVER
GREAT BASIN TO THE SOUTHEAST. DROPPED TEMPERATURES BELOW FREEZING
OVER THE VALLEYS AND LOWER DESERTS FOR TUESDAY NIGHT AND TO A LESSER
EXTENT WEDNESDAY NIGHT TO REFLECT POOLING OF COLD AIR AND CLEAR
SKIES/DRY AIR MAXIMIZING NOCTURNAL COOLING. FOR THE REMAINDER OF THE
WEEK THE UPPER LEVEL RIDGE MOVES SLOWLY EAST ACROSS SOUTHERN
CALIFORNIA AS THE LONG WAVE TROUGH DOWNSTREAM SHIFTS EAST OF 90W
LONGITUDE. THIS SPELLS WARMER DAYS AND COOL NIGHTS...MOSTLY CLEAR
SKIES FOR SOUTHERN CALIFORNIA...A WELCOME MID WINTER RESPITE.
&&
.HYDROLOGY...EXCERPTS FROM EARLY MORNING FORECAST DISCUSSION...
ISENTROPIC LIFT IN THE INCREASING LOW LEVEL WARM AIR ADVECTION
TONIGHT WILL BRING INCREASING AREAS OF LIGHT RAIN TO SAN
BERNARDINO...ORANGE AND WESTERN RIVERSIDE COUNTIES THROUGH DAYBREAK.
THE PRECIP INTENSITY WILL INCREASE SUNDAY MORNING WHEN STRONG PVA
AND VERY STRONG JET DYNAMICS ASSOCIATED WITH A 130 KT 300 MB JET
CONVERGE ON SOCAL. IT IS LOOKING MORE PROBABLE THAT WE WILL SEE
SEVERAL HOURS OF MODERATE TO HEAVY RAIN AND MOUNTAIN SNOW SUNDAY
ALONG AND AHEAD OF THE COLD FRONT...COASTAL AND VALLEYS AREAS WILL
SEE A QUARTER TO THREE QUARTERS OF AN INCH. MOUNTAINS AND FOOTHILLS
WILL SEE FROM ONE TO TWO INCHES. UPPER DESERTS COULD SEE TWO TENTHS
OF AN INCH. RAIN SHADOW EFFECTS WILL STILL LIMIT MOST LOWER DESERTS
AREAS TO A TENTH OF AN INCH OR LESS. THE SNOW LEVEL WILL START
AROUND 6000 FT BUT WILL LOWER TO 4500 FT SUNDAY EVENING. THE SNOW
LEVELS REALLY NOSEDIVE SUNDAY NIGHT...DOWN TO 3500 FEET AS COLD CORE
500 MB TEMPS FALL TO -26C...BUT BY THEN MOST OF THE PRECIP WILL HAVE
MOVED SOUTHEAST. STILL...6 TO 12 INCHES OF SNOW IS POSSIBLE AT THE
HIGHER ELEVATIONS OF THE SAN BERNARDINO AND RIVERSIDE COUNTY
MOUNTAINS. DENSE FOG AND STRONG WINDS COUPLED WITH BURSTS OF
MODERATE TO HEAVY SNOW COULD PRODUCE BRIEF WHITE-OUT CONDITIONS FOR
A FEW HOURS SUNDAY.

.AVIATION...
021945Z...MARINE LAYER DEPTH REMAINS AROUND 5000 FEET OVER THE AREA.
MULTIPLE LAYERS OF STRATOCU WITH BASES RANGING BETWEEN 2500 AND 4500
FEET CONTINUE FROM THE COAST TO THE SLOPES OF THE MOUNTAINS. LITTLE
CHANGE IS EXPECTED THROUGH THE NIGHT THEN BASES SHOULD LOWER SUNDAY
MORNING TO BETWEEN 1500 AND 2500 FEET MSL AS A COLD FRONT MOVES INTO
THE AREA. THE COLD FRONT SHOULD BRING PRECIPITATION TO THE AREA
THROUGH THE DAY WITH VISIBILITIES REDUCED TO 3 TO 5 MILES AT TIMES.
SOUTHWEST WINDS ACROSS THE MOUNTAINS ARE EXPECTED TO PICK UP ON
SUNDAY WITH AND BEHIND THE FRONT WHICH COULD BRING SOME MOUNTAIN
WAVE AND ROTOR ACTIVITY TO THE DESERT AREAS VICINITY OF KPSP ON
SUNDAY. ALSO...THE SOUTHWEST WINDS WOULD NOT FAVOR LOW CEILING
CONDITIONS OR PRECIPITATION AT KPSP BUT MOUNTAINS TO THE WEST COULD
BE OBSCURED IN CLOUDS AND SNOW SHOWERS. HORTON
