COUNTIES...

.SHORT TERM (TODAY THROUGH WEDNESDAY)...
ONLY MINOR CHANGES FOR TODAY BASED ON CURRENT TRENDS. THE 06Z NAM IS
SLIGHTLY SLOWER WITH THE PRECIPITATION...NO MORE THAN 2 TO 3

BE IN THE WARM ADVECTION ZONE...MAINLY THIS MORNING THROUGH EARLY
AFTERNOON. SHOWERS WILL CONTINUE THROUGH THIS AFTERNOON WITH
GREATEST COVERAGE AND AMOUNTS IN SAN DIEGO COUNTY.

ONE CONCERN YESTERDAY WAS THAT THE LOWER LEVEL FLOW IN ADVANCE OF
THIS SYSTEM WOULD BACK MORE THAN SHOWN IN THE MODELS...REDUCING THE
OROGRAPHIC ENHANCEMENT THIS MORNING...ESPECIALLY IN THE SAN
BERNARDINO MOUNTAINS. THIS DOES APPEAR TO BE HAPPENING. AMOUNTS ON
THE SOUTH FACING SLOPES OF THE SAN BERNARDINO MOUNTAINS HAVE BEEN
REDUCED SLIGHTLY.

WITH A COLD DRY ATMOSPHERE IN PLACE PRIOR TO THE PRECIPITATION
ONSET...SNOW LEVELS HAVE LOCALLY BEEN AS LOW AS 2500 TO 3000 FEET.

THE PERIOD OF HEAVIEST AND MOST WIDESPREAD PRECIPITATION IS STILL
EXPECTED TO BE THIS MORNING WITH A TRANSITION TO SHOWERS IN THE
AFTERNOON...MOST NUMEROUS IN SAN DIEGO COUNTY. DECREASING SHOWERS
WILL CONTINUE AT TIMES FOR TONIGHT THROUGH TUESDAY EVENING...BUT
COVERAGE IS EXPECTED TO BE SPOTTY AND OVERALL AMOUNTS LIGHT.

THE NEXT SYSTEM FOR WEDNESDAY WILL BE COLDER AND MORE UNSTABLE WITH
A GREATER POTENTIAL FOR THUNDERSTORMS...BUT THE BULK OF THE MODELS
CONTINUE TO EMPHASIZE SOUTHERNMOST SECTIONS SOUTHWARD INTO NORTHERN
BAJA AS MOST LIKELY TO RECEIVE THIS HEAVIER PRECIPITATION AMOUNTS
FOR LATE TUESDAY NIGHT THROUGH WEDNESDAY.

WITH THE BACKING OF THE LOWER LEVEL FLOW EARLY THIS MORNING...
WORDING IN THE HIGH WIND WARNINGS AND WIND ADVISORIES FOR THE
MOUNTAINS AND DESERTS HAS BEEN MODIFIED TO HAVE THE STRONGER WINDS
DEVELOPING DURING THE MORNING. OTHERWISE...LITTLE CHANGE IS EXPECTED
WITH STRONGEST WINDS FROM MID MORNING THROUGH THE AFTERNOON...
DECREASING IN THE EVENING.

&&

.LONG TERM (THURSDAY THROUGH MONDAY)...
DRY WEATHER AND SLOW WARMING IS EXPECTED FOR THURSDAY THROUGH
SUNDAY. ECWMF AND GFS ENSEMBLE MEAN SHOW THE POTENTIAL FOR A TROUGH
OF LOW PRESSURE TO REDEVELOP ALONG THE WEST COAST EARLY NEXT WEEK
BRINGING A CHANCE OF PRECIPITATION MONDAY AND TUESDAY.

&&

.AVIATION...
151100Z...BASES EXPECTED TO LOWER TO AROUND 2500 FT MSL BY ABOUT 12Z
AS HEAVIER RAIN BEGINS TO MOVE IN. BASES MAY LOCALLY LOWER TO 1000
FT MSL WITH VSBY BRIEFLY GOING TO 1SM OR LESS IN HEAVY RAIN. PERIODS
OF HEAVY RAIN EXPECTED TO MOVE IN THIS MORNING AND CONTINUE THROUGH
AFTERNOON. WINDS WILL ALSO INCREASE THIS MORNING WITH STRONG GUSTY
WINDS ANYWHERE. SNOW LEVEL WILL BE AROUND 3500 FT...LOCALLY TO 2500
