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

WATER VAPOR IMAGERY SHOWS A RIDGE OF HIGH PRESSURE OVER THE WEST
THIS MORNING...WITH VERY DRY AIR SETTLING OVER SOUTHERN CALIFORNIA.
AS A RESULT...SUNNY SKIES PREVAIL...WITH THE ONLY HINTS OF THE
MARINE STRATUS WELL SOUTH ALONG BAJA.  MEANWHILE...THE OFFSHORE
GRADIENTS TO THE NORTH APPEAR TO BE PEAKING NOW...WITH -4.8 MBS
BETWEEN SAN DIEGO AND DAGGETT.  FOR THIS REASON...MOST PLACES ARE
CURRENTLY GUSTING IN THE 25 TO 35 MPH RANGE...WITH THE FAVORED
LOCATIONS THROUGH AND BELOW THE PASSES AND CANYONS GUSTING BETWEEN
45 AND 55 MPH.  THESE WINDS WILL GRADUALLY WEAKEN THROUGH THE DAY.
THE GRADIENT WILL THEN BECOME MORE EASTERLY TONIGHT...WITH THE
THREAT OF GUSTY EAST WINDS CONTINUING ACROSS THE SAN DIEGO COUNTY
MOUNTAINS AND FOOTHILLS.  THE 12Z WRF IS SHOWING THIS SECONDARY PEAK
TONIGHT WELL...WITH 35 TO 45 KT WINDS AT 850 MB...SO WILL LIKELY
NEED TO CONSIDER EXTENDING THIS PORTION OF THE WIND ADVISORY.
OTHERWISE...EXPECT MUCH WARMER CONDITIONS TO PREVAIL WEST OF THE
MOUNTAINS TODAY.  DAYTIME TEMPERATURES WILL LIKELY BE 10 TO 15
DEGREES ABOVE AVERAGE...WITH A FEW LOCATIONS POTENTIALLY FLIRTING
WITH THEIR RECORDS.  THESE VERY WARM AND DRY CONDITIONS WILL ALSO
CONTINUE INTO SUNDAY...WITH TEMPERATURES SIMILAR TO OR EVEN SLIGHTLY
WARMER THAN TODAY.

COOLER CONDITIONS WILL THEN DEVELOP FOR THE FIRST PART OF THE WORK
WEEK...ESPECIALLY FOR AREAS WEST OF THE MOUNTAINS...AS A TROUGH OF
LOW PRESSURE MOVES INLAND ACROSS NORTHERN CALIFORNIA.  THE MARINE
LAYER WILL LIKELY RETURN TO THE COASTAL AREAS DURING THIS
TIME...WITH PATCHY LOW CLOUDS AND FOG POSSIBLE ALONG THE COAST
DURING THE LATE NIGHT AND EARLY MORNING HOURS.  ONSHORE FLOW WILL
RETURN AND STRENGTHEN AS WELL ON MONDAY...WITH SOME GUSTY WEST WINDS
POTENTIALLY DEVELOPING IN THE MOUNTAINS AND DESERTS ONCE AGAIN.
THAT BEING SAID...GUSTY OFFSHORE WILLS WILL DEVELOP LATE ON
TUESDAY...AS HIGH PRESSURE BEGINS TO REBUILD.  THEREFORE...DRY AND
WARMER CONDITIONS WILL LIKELY RETURN FOR THE LATTER PART OF THE WORK
WEEK AND FIRST PART OF THE WEEKEND.
