AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
800 AM PST TUE MAR 7 2006

.SYNOPSIS...A FAST MOVING LOW PRESSURE TROUGH ALOFT WILL BRING
SCATTERED RAIN SHOWERS...AND SNOW SHOWERS WITH STRONG...GUSTY WINDS
IN THE MOUNTAINS AND HIGH DESERTS THROUGH TONIGHT. DRY AND PARTLY
CLOUDY WEATHER IS EXPECTED FOR WEDNESDAY AND THURSDAY UNDER WEAK
HIGH PRESSURE ALOFT. A STRONG POLAR JET STREAM WILL MOVE OVER THE
AREA BY THE END OF THE WEEK...BRINGING MORE SHOWERS AND VERY CHILLY
AIR. VERY LOW SNOW LEVELS ARE EXPECTED BY SATURDAY AND SUNDAY. THERE
WILL ALSO BE STRONG GUSTY WINDS AT TIMES MAINLY OVER THE MOUNTAINS
AND DESERTS.

&&

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

SHORTWAVE TROUGH THAT MOVED THROUGH OVERNIGHT WAS EXITING TO THE
EAST AT THIS TIME WHILE ANOTHER SHORTWAVE TROUGH WAS SWINGING
THROUGH THE POINT CONCEPTION AREA. THIS NEXT SHORTWAVE WILL MOVE
THROUGH LATE THIS AFTERNOON AND EARLY EVENING. SATELLITE IMAGERY
INDICATES MOSTLY HIGH CLOUDS ASSOCIATED WITH THIS NEXT SHORTWAVE AND
RADAR INDICATES JUST SOME SCATTERED SHOWERS. HOWEVER...SHORTWAVE
COULD PICK UP A LITTLE MORE MOISTURE AS IT MOVES SOUTHEAST ACROSS
THE COASTAL WATERS BEFORE MOVING ONSHORE THIS AFTERNOON.

SHORTWAVE RIDGE BUILDS BEHIND THE NEXT SHORTWAVE TROUGH AND HOLDS
THROUGH THURSDAY WITH DRYING WEDNESDAY AND THURSDAY.

A MUCH STRONGER AND COLDER SHORTWAVE MOVES SOUTHEAST FROM THE GULF
OF ALASKA AND BEGINS TO MOVE INTO SOUTHERN CALIFORNIA ON FRIDAY. THE
12Z NAM MODEL DOES NOT SHOW MUCH PRECIPITATION WITH THIS SHORTWAVE
BUT THE NAM HAS BEEN UNDERESTIMATING THE PRECIPITATION FROM THE
PREVIOUS SYSTEMS INCLUDING THE SHORTWAVE THAT MOVED THROUGH LAST
NIGHT. THE 06Z GFS INDICATES MOST OF THE MOISTURE WILL BE HEADING
INTO THE COASTAL AREAS FROM ORANGE COUNTY SOUTHWARD TO SAN DIEGO
FRIDAY NIGHT AND SATURDAY AS A COLD FRONT MOVES THROUGH. A COLD
TROUGH FOLLOWS FOR SATURDAY NIGHT AND SUNDAY. 1000 TO 500 MB
THICKNESS IS STILL EXPECTED TO BE QUITE LOW...AROUND 528 DM ACROSS
SAN DIEGO BY SATURDAY AFTERNOON INTO SUNDAY. A COMBINATION OF THE
COLD AIR ALOFT AND WATER TEMPERATURE IN THE UPPER 50S AS WELL AS ANY
SOLAR HEATING SHOULD FAVOR A VERY ACTIVE PERIOD OF CONVECTION OVER
THE WEEKEND WITH THIS TROUGH. TROUGH SLOWLY MOVES TO THE EAST MONDAY
WITH RISING THICKNESS AND RIDGING BY THE MIDDLE OF NEXT WEEK.

NO UPDATES ARE PLANNED AT THIS TIME.

.AVIATION...
TEMPORARY AND PARTIAL DRYING OF LOW LEVELS TODAY BEFORE WEAK COLD
FRONT MOVES ACROSS THE AREA THIS EVENING. EXPECT SCATTERED CLOUD
LAYERS TO BECOME BROKEN AFTER 0000 UTC TO 7500 FEET. IN ADDITION TO

TURBULENCE. FREEZING LEVEL LOWERING TO AROUND 5500 FEET IN THE
FRONTAL BAND...LEADING TO THE THREAT OF LIGHT TO MODERATE MIXED
ICING BETWEEN FL050 AND FL080 TONIGHT. WINDS AT  FL100 SOUTHWEST 35
KT TODAY...INCREASING TO WEST NORTHWEST 55 KT FOLLOWING FRONT FOR
ABOUT A 3 HOUR PERIOD...THEN SLOWLY DIMINISHING TO NORTH 30 KNOTS BY
08/1800 UTC. EXPECT GREATEST TURBULENCE WHEN WINDS ARE MORE
PERPENDICULAR TO RIDGE LINES...SO OVER AND DOWNSTREAM OF SAN
BERNARDINO AND SAN JACINTO MOUNTAINS TODAY...AND OVER PALOMAR
MOUNTAINS...LAGUNA MOUNTAINS...AND ANZA BORREGO DESERT THIS EVENING.
