.SYNOPSIS... HIGH PRESSURE ALOFT WILL BRING SUNNY WEATHER TODAY. A

FAIR WEATHER RETURNS THURSDAY THROUGH SUNDAY.

&&

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

HIGH PRESSURE OVER THE GREAT BASIN AND A VERY DRY AIRMASS OVER THE
SOUTHWEST CONTRIBUTED TO A VERY COLD NIGHT WITH TEMPERATURES 5 TO 15
DEGREES LOWER THAN YESTERDAY MORNING. LOWS FELL INTO THE UPPER 20S
AND LOWER 30S IN THE COLDEST VALLEYS...AND INTO THE MID 30S TO LOW
40S IN MOST OTHER COASTAL AND VALLEYS LOCATIONS. EVEN THE COLDEST
LOWER DESERT STATIONS FELL INTO THE UPPER 30S. BIG BEAR WAS THE
COLDEST OF ALL THIS MORNING WITH A LOW OF 1.

TODAY WILL BE SUNNY AS THE RIDGE AXIS DRIFTING OVERHEAD. TONIGHT
WILL BE ANOTHER CLEAR...COLD NIGHT AND MAY BE NEARLY AS COLD AS LAST
NIGHT. OFFSHORE WINDS WILL BE LIGHTER WHICH WILL CONTRIBUTE TO
EFFICIENT COOLING. A FROST ADVISORY MAY BE ISSUED FOR THE VALLEYS
AND SECTIONS OF THE LOWER DESERTS.

ON WEDNESDAY A WEAK TROUGH APPROACHING FROM THE WEST WILL TRAVERSE
THE SOUTHWEST WEDNESDAY NIGHT. THE MODELS HAVE WEAKENED THIS SYSTEM
WITH EACH SUCCESSIVE RUN AND THE CHANCES FOR SIGNIFICANT PRECIP
WEDNESDAY NIGHT ARE LOW. EXPECT TO SEE ONLY A FEW HUNDREDTHS OF AN
INCH OF PRECIP LATE WEDNESDAY AFTERNOON THROUGH WEDNESDAY NIGHT WITH
THE BEST CHANCES ALONG THE WEST FACING SLOPES OF THE MOUNTAINS. A
TRACE OF SNOW IS POSSIBLE ABOVE ABOUT 6500 FT. GUSTY WEST WINDS WILL
DEVELOP OVER THE RIDGES AND LOCALLY INTO THE DESERTS BUT SHOULD
GENERALLY REMAIN BELOW ADVISORY STRENGTH.

THURSDAY THROUGH SUNDAY...WEAK RIDGING OR ZONAL FLOW THOUGH THE
PERIOD FOR GENERALLY DRY WEATHER. THE GFS SENDS A WEAK PACIFIC
SHORTWAVE ACROSS SOUTH-CENTRAL CALIFORNIA FRIDAY...FOLLOWED BY A
SECOND EVEN WEAKER WAVE SATURDAY. THE FIRST WAVE WILL BRING CLOUDS
AND COOL WEATHER FRIDAY ALONG WITH PERHAPS SOME VERY LIGHT SHOWERS
ACCORDING TO THE GFS. THE ECMWF IS FARTHER NORTH AND WEAKER AND DOES
NOT GENERATE ANY LIGHT PRECIP. WILL MAINTAIN A DRY FORECAST AT THIS
TIME AND EVALUATE THE CHANCES FOR LIGHT PRECIP AS THE SYSTEM ENTER
THE HIGH RESOLUTION MODEL WINDOW.
