ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

NATIONAL WEATHER SERVICE SAN DIEGO CA
145 PM PDT THU MAY 22 2014

.SYNOPSIS...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS THE
MOUNTAINS AND DESERTS THROUGH THIS EVENING...WITH ISOLATED SHOWERS
AND THUNDERSTORMS POSSIBLE WEST OF THE MOUNTAINS.  ALTHOUGH DRIER
CONDITIONS WILL DEVELOP ON FRIDAY...AS THE TROUGH MOVES EAST...SOME
LINGERING INSTABILITY AND MOISTURE WILL CONTINUE THE THREAT OF
SHOWERS OVER THE MOUNTAINS AND DESERTS.  DRY AND WARMER CONDITIONS
WILL THEN DEVELOP FOR THE HOLIDAY WEEKEND...WITH SOME COASTAL LOW
CLOUDS AND FOG POSSIBLE EACH NIGHT.  A GRADUAL COOLING TREND WILL
THEN DEVELOP FOR THE MIDDLE AND LATTER PART OF THE WORK WEEK.

&&

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

WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL LOW OVER SOUTHERN
CALIFORNIA THIS AFTERNOON.  AS A RESULT...SCATTERED SHOWERS AND
THUNDERSTORMS ARE DEVELOPING OVER THE MOUNTAINS AND DESERTS.
CURRENTLY...AN URBAN AND SMALL STREAM FLOOD ADVISORY IS IN EFFECT
FOR A PORTION OF THE SAN DIEGO COUNTY DESERTS...EAST OF SHELTER
VALLEY.  MEANWHILE...A THICK BLANKET OF LOW CLOUDS LINGERS WEST OF
THE MOUNTAINS.  ALTHOUGH THERE ARE A FEW BREAKS IN THE
CLOUDS...MAINLY OVER THE INLAND EMPIRE...THERE ARE NOW ENOUGH HIGH
CLOUDS LIMITING THE SURFACE HEATING.  THE HRRR AND LOCAL WRF ARE
STILL INDICATING THAT THE ELSINORE CONVERGENCE ZONE WILL GENERATE
SOME ACTIVITY LATE THIS AFTERNOON AND DURING THE EARLY EVENING
HOURS...SO HAVE KEPT A MENTION OF SHOWERS AND THUNDERSTORMS IN THE
FORECAST FOR THE INLAND VALLEYS.  HOWEVER...CONFIDENCE IS LOW GIVEN
THE CURRENT SATELLITE TRENDS.

THIS UPPER LEVEL TROUGH WILL SLOWLY SHIFT EAST TONIGHT AND DURING
THE DAY ON FRIDAY.  AS A RESULT...MOST AREAS WILL SEE DRIER AND
WARMER CONDITIONS DEVELOP.  HOWEVER...THERE WILL BE ENOUGH LINGERING
INSTABILITY AND MOISTURE OVER THE MOUNTAINS AND DESERTS...THAT
ISOLATED SHOWERS AND THUNDERSTORMS COULD DEVELOP ONCE AGAIN.  HIGH
PRESSURE THEN BUILD BACK ACROSS SOUTHERN CALIFORNIA FOR THE MEMORIAL
DAY WEEKEND...WITH EVEN WARMER AND DRIER CONDITIONS DEVELOPING.  A
SHALLOW MARINE LAYER WILL REMAIN ALONG THE COAST THOUGH...WITH NIGHT
AND MORNING LOW CLOUDS AND FOG POSSIBLE.  ANOTHER TROUGH WILL THEN
DIG ALONG THE WEST COAST BY THE MIDDLE PART OF THE WORK WEEK...WITH
COOLER CONDITIONS AND A MORE EXTENSIVE MARINE LAYER DEVELOPING ONCE
AGAIN.
