SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
200 PM PDT MON MAY 10 2010

.SYNOPSIS...

A COLD AND VIGOROUS STORM SYSTEM WILL TRACK ACROSS INTERIOR
CALIFORNIA AND SOUTHERN NEVADA OVERNIGHT...BRINGING STRONGER WINDS
TO PORTIONS OF SOUTHERN CALIFORNIA AND CONTINING THROUGH TUESDAY
NIGHT. DRY WEATHER IS GENERALLY FORECAST THROUGH THE WEEK...WITH THE
EXCEPTION OF SCATTERED SNOW SHOWERS DEVELOPING LATE TONIGHT THROUGH
TUESDAY MORNING ACROSS NORTH FACING MOUNTAIN SLOPES. CONTINUED COOL
THROUGH TUESDAY...THEN WARMING TREND REMAINDER OF WEEK.

&&

.SHORT TERM (TONIGHT-THU)...
COLD AND VIGOROUS UPPER LEVEL LOW PRESSURE SYSTEM CURRENTLY CENTERED
OVER NORTHERN CALIFORNIA THIS AFTERNOON IS EXPECTED TO DIVE SOUTHEAST
TONIGHT AND BE CENTERED NEAR LAS VEGAS BY 12Z TUESDAY. THIS WILL BE
YET ANOTHER INSIDE SLIDER SYSTEM FOR SOUTHERN CALIFORNIA...BRINGING
ANOTHER REINFORCING SHOT OF STRONGER WINDS AND COLD TEMPERATURES.

WIND ADVISORIES ALREADY IN EFFECT FOR THE MOUNTAINS...ANTELOPE
VALLEY...AND SBA SOUTH COAST THIS AFTERNOON. UPPER LEVEL WIND SUPPORT
WILL INCREASE AFTER MIDNIGHT ACROSS THE REGION...ALONG WITH A GOOD
SURGE OF COLD AIR ADVECTION. THIS COMBINATION WILL LEAD TO INCREASING
AREAL COVERAGE AND INTENSITY OF WINDS ACROSS THE FORECAST AREA AFTER
MIDNIGHT AND CONTINUING THROUGH TUESDAY EVENING. WITH THE FLOW BECOMING
MORE NORTHERLY...THE STRONGEST WINDS ARE EXPECTED TO BE FOCUSED ACROSS
THE PASSES AND CANYONS OF THE SANTA YNEZ RANGE...AS WELL AS THE INTERSTATE
5 CORRIDOR IN THE LA COUNTY MOUNTAINS. THESE AREAS ARE UNDER A HIGH WIND
WARNING WHERE DAMAGING GUSTS TO 60 MPH CAN BE EXPECTED.

THE SURGE OF NORTHERLY WINDS IS EXPECTED TO SPREAD INTO PORTIONS OF THE
LA BASIN LATER TONIGHT AND TUESDAY. AS A RESULT...HAVE INCLUDED
SANTA CLARITA AND SAN FERNANDO VALLEYS IN THE ADVISORY AREA FOR THIS TIME
PERIOD. AS WE DRAW CLOSER TO THE EVENT...OTHER LOCATIONS MAY NEED TO BE
INCLUDED IN THE WIND ADVISORY. THE NORTHERLY WINDS WILL CONTINUE TO KEEP
FAIRLY COOL READINGS ACROSS MUCH OF THE AREA ON TUESDAY...BUT COULD SEE
SOME DOWNSLOPE WARMING INTO THE MID 70S ACROSS FAVORED AREAS SUCH AS
THE SBA SOUTH COAST AND LA BASIN.

WHILE THIS SYSTEM IS EXPECTED TO TAKE AN INLAND TRACK AND BE RATHER DEFICIENT
IN MOISTURE...THERE DOES APPEAR TO BE ENOUGH MOISTURE ACROSS THE NORTH
FACING SLOPES TO PRODUCE A CHANCE OF SHOWERS LATER TONIGHT AND TUESDAY
MORNING. THE 18Z NAM CONTINUES TO ADVERTISE 850 MB TEMPERATURES DROPPING
AS LOW AS -2 DEGREES CELSISUS BY 12Z TUESDAY ACROSS THE NORTH FACING
SLOPES. AS A RESULT...HAVE LOWERED SNOW LEVELS TO AROUND 4000 FEET LATER
TONIGHT FOR THE NORTH SLOPES. WHILE ACCUMULATIONS ARE EXPECTED TO BE
RATHER LIGHT (2 INCHES OR LESS)...THE POTENTIAL FOR SNOW SHOWERS IN
MID MAY ACROSS INTERSTATE 5 NEAR THE GRAPEVINE IS CERTAINLY
NOTEWORTHY.

AS THE LOW LEVEL FLOW BEGINS TO TURN WEAKLY OFFSHORE ON WEDNESDAY
MORNING...LOOK FOR AIR MASS TO BEGIN MODIFYING. WARMING TREND ON TAP
FOR MOST AREAS...WITH SOME VALLEY AREAS EXPECTED TO CLIMB BACK INTO THE
LOWER 80S. ANOTHER WEAK UPPER LOW WILL TRACK DOWN THE COAST OF CALIFORNIA
ON THURSDAY AND BRING A FEW CLOUDS...OTHERWISE VERY LITTLE IMPACT ON
OUR WEATHER.

.LONG TERM (FRI-MON)...
TEMPERATURES ARE EXPECTED TO CONTINUE NUDGING UPWARD ON FRIDAY ACROSS
INLAND AREAS AS THICKNESS VALUES CONTINUE TO RISE. THE WARMEST DAY
FOR MANY AREAS WILL LIKELY BE SATURDAY AS A WEAK UPPER LEVEL RIDGE
OF HIGH PRESSURE BUILDS OVER SOUTHERN CALIFORNIA. A WEAK UPPER LEVEL
TROUGH OF LOW PRESSURE COULD BRING SOME CLOUDS AND A COOLING TRNED
TO THE REGION BY MONDAY.

&&

.AVIATION...10/1945Z.
BKN CLOUDS FOR THE VALLEYS AND SCT CLOUDS FOR THE COAST TODAY.
DECREASING CLOUDS FOR ENTIRE AREA TONIGHT AND TUESDAY. WINDS WILL
INCREASE THIS AFTERNOON INTO TONIGHT...PRODUCING AREAS OF TURBULENCE
AND LOW LEVEL WIND SHEAR THROUGH TUESDAY.

KLAX...SCT CLOUDS TODAY AND CLEAR TONIGHT AND TUESDAY WITH VFR
CONDITIONS AND GUSTY WINDS.

KBUR...BKN CLOUDS THIS AFTERNOON THEN CLEAR TONIGHT AND TUESDAY.
POSSIBLE LOW LEVEL WIND SHEAR...ESPECIALLY TUESDAY MORNING.
