AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
238 AM PDT THU APR 28 2016

.SYNOPSIS...
LOW PRESSURE ALOFT WILL BRING SOME SHOWERS AND A SLIGHT CHANCE OF
THUNDERSTORMS TO THE REGION TODAY, MOST LIKELY IN AND NEAR THE
MOUNTAINS. STRONG GUSTY WINDS IN THE MOUNTAINS AND DESERTS WILL
DECREASE TODAY. FAIR WEATHER WILL RETURN FRIDAY BEFORE ANOTHER
SYSTEM FROM THE NORTH SATURDAY BRINGS A SLIGHT CHANCE OF SHOWERS
OR THUNDERSTORMS SATURDAY AFTERNOON THROUGH SUNDAY AFTERNOON. FAIR
AND WARMER WEATHER WILL ARRIVE MONDAY AND TUESDAY UNDER HIGH
PRESSURE.

&&

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

A LOW PRESSURE TROUGH HAS DROPPED INTO SOUTHERN CALIFORNIA THIS
MORNING. LOTS OF SHOWERS HAVE DEVELOPED IN SAN BERNARDINO COUNTY,
INCLUDING THE HIGH DESERT, MOUNTAINS, AND EVEN NORTHERN INLAND
EMPIRE. AMOUNTS ARE GENERALLY LESS THAN A TENTH INCH, BUT A COUPLE
GAGES HAVE SHOWN HEAVIER. ELSEWHERE: ISOLATED TRACE AMOUNTS IN
SPRINKLES OR LIGHT SHOWERS. WE EXPECT THE SHOWERS TO TAKE A
SOMEWHAT INLAND TRACK DURING THE DAY MOST LIKELY IN THE MOUNTAINS
AND COASTAL FOOTHILLS. JUST ENOUGH INSTABILITY DEVELOPS THIS
AFTERNOON FOR A SLIGHT CHANCE OF THUNDERSTORMS, BUT JUST BARELY.
WINDS HAVE BEEN STRONG WITH GUSTS EXCEEDING 45 MPH AT SEVERAL
STATIONS ALONG THE MOUNTAIN/DESERT TRANSITION ZONE IN RIVERSIDE
AND SAN DIEGO COUNTY. THE WINDS WILL DECREASE THIS MORNING, BUT
HANG ON RATHER BRISK, ALTHOUGH NOT ADVISORY STRENGTH, THROUGH THE
EVENING. SNOW WILL STAY ABOVE ABOUT 6500 FEET AND WILL NOT AMOUNT
TO MUCH. THE TROUGH MOVES OUT TONIGHT. FRIDAY AND SATURDAY WILL
FEATURE A DEEP MARINE LAYER PROPPED UP BY A COASTAL EDDY WITH SOME
CLOUDS IN THE COASTAL BASIN DURING THE NIGHTS AND MORNINGS. THE
NEXT LOW PRESSURE TROUGH DROPS DOWN FROM THE NORTH SATURDAY. THIS
ONE HAS LIMITED MOISTURE LIKE OUR CURRENT SYSTEM. THERE ARE LOTS
OF SIMILARITIES WITH THE PRECIP CHANCE, AMOUNT, AND DISTRIBUTION.
MOST PLACES WILL RECORD NONE, BUT SOME CONVECTIVE SHOWERS COULD
PRODUCE BRIEFLY HEAVY RAIN, AND THERE IS A SLIGHT CHANCE OF
THUNDERSTORMS SATURDAY AFTERNOON. THAT TROUGH SLOWLY MOVES OUT ON
SUNDAY. A RIDGE OF HIGH PRESSURE BUILDS MONDAY AND TUESDAY AHEAD
OF A DIGGING TROUGH OVER THE OCEAN. THAT WILL BRING MUCH WARMER
WEATHER AND ABOVE AVERAGE TEMPS. CONFIDENCE IS STILL LOW, BUT
GROWING, THAT THE PACIFIC TROUGH WILL GRAB SOME MOISTURE FROM THE
SOUTH AND MOVE SHOWERS INTO SOUTHERN CALIFORNIA AROUND THURSDAY
AND FRIDAY.
