SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
306 AM PST WED FEB 28 2007

.SHORT TERM...
COLD MOIST NORTHWEST FLOW OVERHEAD IS CREATING QUITE A FEW SHOWERS.
THE MOUNTAINS ARE PROTECTING SOUTHERN SBA AND VTA COUNTIES. Z-LVL
NEAR 3500 FEET OVER LAX AND NEAR 3000 FEET NORTH WITH SNOW LEVELS
LOCALLY DOWN TO 2500 FEET. FT TEJON AT I-5 HAS STEADY SNOW WITH THE
NORTH UPSLOPE FLOW. INDEED THE FOOTHILLS OF THE VALLEYS COULD SEE
SNOW IN THE AIR...BUT NON STICKING. EXCEPT ON THE NORTH SLOPES THERE
WILL NOT BE MUCH PRECIP. SNOW AND BLOWING SNOW ADVISORY LOOKS GOOD
AND IT WILL HAVE TO BE CONVERTED TO A WIND ADVISORY WITH THE SNOW
STOPS AS MOUNTAIN WINDS WILL INCREASE TO ADVISORY LEVELS LATE THIS
AFTERNOON.

WINDS WILL THEN BE THE PROBLEM THROUGH FRIDAY AS A STRONG NW THEN N
GRADIENT SETS UP. COASTAL SITES THIS AFTERNOON WILL SEE 15 TO 25 MPH
THE MOUNTAINS AND ANTELOPE VALLEY WILL SEE 30 TO 40 MPH WINDS WITH
HIGHER GUSTS AND ADVISORIES WILL LIKELY BE NEEDED. CONTINUED STRONG
NORTHWEST WINDS THURSDAY WILL BRING LOCAL GUSTY CANYON WINDS TO THE
SANTA BARBARA SOUTH COAST. THEN FRIDAY NIGHT AND SATURDAY MORNING
THE FLOW WILL BE NORTHERLY AND ALL THE NORTH TO SOUTH CANYONS WILL
LIGHT UP.

NORTHEAST FLOW AND A RIDGE FOR THE WEEKEND WILL MAKE FOR A VERY NICE
COUPLE OF DAYS HIGHS IN THE 70S FOR THE COASTS AND VALLEYS WITH LOTS
OF SUNSHINE.

.LONG TERM...
EC AND GFS ARE NOT IN THE BEST OF AGREEMENT FOR THE EXTENDED PERIOD.
MONDAY LOOKS A LITTLE COOLER AS THE FLOW SWITCHES BACK TO ONSHORE.
THE RIDGING SWITCHES TO A SW FLOW AHEAD OF A TROF. AT THIS TIME THE
GFS KEEPS THE MOISTURE OUT OF THE AREA TUESDAY. IF THE GFS IS TO BE
BELIEVED (NOT A GREAT IDEA) A FRONT WILL MOVE THROUGH WEDNESDAY.
