930 AM PDT SUN APR 16 2006

.SYNOPSIS...THE MARINE LAYER WILL BRING LOW CLOUDS AND LOCAL FOG
WEST OF THE MOUNTAINS IN THE NIGHTS AND MORNINGS EARLY THIS WEEK. AN
UPPER LEVEL LOW PRESSURE TROUGH WILL MOVE PAST TO THE NORTH CAUSING
LOCAL STRONG GUSTY WIND IN THE MOUNTAINS AND DESERTS TONIGHT AND

OFFSHORE FLOW. UPPER LEVEL LOW PRESSURE WILL BRING MORE CLOUDS AND
COOLING TOWARD THE END OF THE WEEK.

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

STRATUS WAS INTO THE LOWER COASTAL MOUNTAIN SLOPES THIS MORNING. THE
12Z NKX SOUNDING HAD AN INVERSION BASED NEAR 4300 FT WITH DRY WSW
WINDS ALOFT. STRONG ONSHORE GRADIENTS WITH ABOUT 10 MB SAN-TPH AND
6 MB SAN-IPL.

AN UPPER TROUGH WILL MOVE PAST TO THE N LATE TONIGHT AND EARLY MON.
THIS WILL MAINTAIN A DEEP MARINE LAYER FOR LOTS OF LOW CLOUDS W OF
THE MOUNTAINS. HOWEVER...THE COOLER AIR ALOFT ASSOCIATED WITH THE
TROUGH WILL WEAKEN THE INVERSION FOR LOTS OF BREAKS IN THE OVERCAST.
SKIES SHOULD CLEAR OUT BEHIND THE TROUGH MON AFTERNOON. STRONGER
ONSHORE GRADIENTS AND INCREASING WINDS ALOFT WILL CAUSE LOCAL STRONG
GUSTY WINDS IN THE MOUNTAINS AND DESERTS THIS AFTERNOON AND MONDAY.
THE WINDS MAY REACH NEAR ADVISORY STRENGTH. CONTINUED BELOW SEASONAL
TEMPS IN MOST AREAS MON. A LITTLE STRATUS MIGHT LINGER AROUND TUE
MORNING...OTHERWISE WEAK HIGH PRESSURE ALOFT AND WEAK OFFSHORE FLOW
WILL BRING GENERALLY FAIR AND SIGNIFICANTLY WARMER DAYS TUE AND WED.

LONGER RANGE PROGS INDICATE AN UPPER TROUGH APPROACHING FROM THE NW
WILL BRING MORE CLOUDS AND COOLING DURING THE SECOND HALF OF THE
WEEK. THERE WILL BE A SMALL CHANCE OF PRECIP BY FRI AND THE WEEKEND
BUT STILL TOO FAR OUT AND TOO MUCH UNCERTAINTY TO INCLUDE IN THE
ZONES.

&&

.AVIATION...
MARINE LAYER DEPTH AROUND 4200 FEET THIS MORNING BASED ON THE 12Z
NKX SOUNDING AND RECENT TOP REPORTS OUT OF KSAN. EXPECT SOME
