COOLING...AND DEEPENING MARINE LAYER...AND GUSTY WEST WINDS IN THE

SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

A THIN BAND OF HIGH CLOUDS WAS MOVING IN FROM THE NORTHWEST THIS

JUST WEST OF SAN NICHOLAS ISLAND. SURFACE PRESSURE GRADIENTS ARE
TRENDING ONSHORE...NEARLY NEUTRAL TO THE HIGH DESERTS AND ONSHORE TO

A WEAK SHORT WAVE TROUGH MOVING INTO THE PACIFIC NORTHWEST TODAY

EXPECTED AS ONSHORE FLOW RETURNS. HIGHS WEST OF THE MOUNTAINS WILL
GENERALLY BE AROUND 5 TO 10 DEGREES LOWER THAN YESTERDAY. MARINE
LAYER LOW CLOUDS AND FOG WILL GRADUALLY REDEVELOP THIS
AFTERNOON...MOVING INTO THE COASTAL AREAS BY THIS EVENING.

AN UPPER LEVEL TROUGH WILL MOVE THROUGH CALIFORNIA DURING THE DAY
SATURDAY. AS THE TROUGH APPROACHES...THE MARINE LAYER WILL RAPIDLY
DEEPEN WITH STRATUS EXTENDING INTO THE COASTAL SLOPES OF THE
MOUNTAINS BY SATURDAY MORNING. WHILE MOISTURE ASSOCIATED WITH THIS
SYSTEM IS LIMITED...THE VERY DEEP MARINE LAYER AND THE SHORT WAVE
MOVING THROUGH SHOULD BE ENOUGH TO SQUEEZE OUT SOME DRIZZLE AND
LIGHT RAIN OVER AND WEST OF THE MOUNTAINS. PRECIPITATION
ACCUMULATIONS ARE ONLY EXPECTED TO BE A FEW HUNDREDTHS OF AN
INCH...WITH LOCAL AMOUNTS AROUND ONE-TENTH INCH ALONG THE COASTAL
SLOPES OF THE MTNS. LIGHT SNOW FLURRIES ARE POSSIBLE ABOVE 5500 FT.

MODERATE WESTERLY MID-LEVEL WINDS...AROUND 30-40 KT AT 700 MB...WILL
LEAD TO GUSTY WINDS IN THE MOUNTAINS AND DESERTS. WINDS ARE MOSTLY
EXPECTED TO BE ADVISORY STRENGTH WITH GUSTS 45-55 MPH. LOCAL GUSTS
60-65 MPH MAY BE POSSIBLE IN THE FAVORED LOCATIONS...MAINLY THROUGH
THE BANNING PASS...THE FAR SOUTHEAST PORTION OF SAN DIEGO
COUNTY...AND ALONG THE RIDGETOPS OF THE RIVERSIDE AND SAN DIEGO
COUNTY MOUNTAINS. WINDS ARE EXPECTED TO BE THE STRONGEST SATURDAY
AFTERNOON THROUGH SUNDAY MORNING...GRADUALLY WEAKENING SUNDAY
AFTERNOON AND EVENING.

A BRIEF PERIOD OF FAIR WEATHER WILL RETURN FOR SUNDAY AFTERNOON
THROUGH MONDAY MORNING AS WEAK SHORT WAVE RIDGING MOVES OVER THE

CHANCE OF LIGHT PRECIPITATION MONDAY MORNING THROUGH TUESDAY
AFTERNOON...AND POTENTIALLY STRONG GUSTY ONSHORE WINDS IN THE
MOUNTAINS AND DESERTS. THE SNOW LEVEL WILL FALL TO AROUND 5000 FT BY
TUESDAY MORNING...THOUGH NO SIGNIFICANT ACCUMULATION IS EXPECTED.
COOL AND UNSETTLED WEATHER WILL THROUGH WEDNESDAY. MODEL SOLUTIONS
BEGIN TO DIVERGE THURSDAY WITH THE EC...GEM...AND DGEX SHOWING WEAK
RIDGING BUILDING IN AND THE GFS SHOWING ANOTHER TROUGH SLIDING DOWN
THE COAST. WILL STICK WITH THE MORE CONSISTENT WARMER AND DRIER
SOLUTION FOR NOW.
