NATIONAL WEATHER SERVICE SAN DIEGO CA
222 PM PDT FRI APR 18 2014
.SYNOPSIS...
ISOLATED SHOWERS WILL CONTINUE IN THE MOUNTAINS AND HIGH DESERTS 
THROUGH THIS EVENING...AS A WEAK UPPER LEVEL LOW SHIFTS INLAND OVER 
SOUTHERN CALIFORNIA.  A GRADUAL WARMING TREND WILL THEN DEVELOP FOR 
THIS EASTER WEEKEND AND EARLY NEXT WEEK...AS HIGH PRESSURE BUILDS 
BACK ACROSS THE REGION.  MARINE STRATUS WILL LINGER NEAR THE COAST 
THOUGH...WITH AREAS OF NIGHT AND MORNING LOW CLOUDS AND FOG 
POSSIBLE.  A STRONGER AND COLDER TROUGH WILL THEN MOVE INLAND ACROSS 
THE WEST ON TUESDAY AND WEDNESDAY...WITH COOLER CONDITIONS RETURNING 
ONCE AGAIN.  A DEEPER MARINE LAYER WILL BE POSSIBLE WEST OF THE 
MOUNTAINS...WITH STRONG AND GUSTY WEST WINDS IN THE MOUNTAINS AND 
DESERTS.  A MINOR WARMING TREND WILL DEVELOP FOR THE REMAINDER OF 
THE WEEK.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
FORECAST UPDATED TO ADD SLIGHT CHANCE OF SHOWERS TO ALL MOUNTAAIN 
AREAS THIS AFTERNOON AND EARLY EVENING.
WATER VAPOR IMAGERY CONTINUES TO SHOW A WEAK UPPER LEVEL LOW OPENING 
INTO A WAVE AND MOVING INLAND ACROSS SOUTHERN CALIFORNIA THIS 
AFTERNOON.  AS A RESULT...THE CLOUDS ARE THINNING ENOUGH THAT SOME 
SUN IS STARTING TO BRIGHTEN THIS DREARY DAY.  ISOLATED SHOWERS ARE 
ALSO FORMING OVER THE SAN BERNARDINO MOUNTAINS...MAINLY EAST OF 
INTERSTATE 15.  SO FAR...RADAR IMAGERY HAS NOT SHOWN ANYTHING OVER 
ABOUT 40 DBZ...BUT MODERATE SHOWERS ARE BEING REPORTED IN THE BIG 
BEAR AREA...MIXED WITH SMALL GRAUPEL AT TIMES.  GAGES IN THAT AREA 
ARE REPORTING BETWEEN 0.07 AND 0.2 INCHES...WHICH IS QUITE 
RESPECTABLE CONSIDERING THE DRY LAYER ON THE 12Z KNKX SOUNDING THIS 
MORNING.  THESE ISOLATED SHOWERS WILL LIKELY CONTINUE THROUGH EARLY 
THIS EVENING.  OTHERWISE...EXPECT PRIMARILY DRY CONDITIONS TO 
PREVAIL...WITH A FEW SPRINKLES AT BEST ELSEWHERE.  VISIBLE IMAGERY 
ALSO SHOWS THE MARINE STRATUS LURKING OVER THE COASTAL WATERS...SO 
EXPECT IT TO SURGE INLAND AGAIN THIS EVENING...EVENING THOUGH IT 
WILL LIKELY BE A LITTLE SHALLOWER THAN LAST NIGHT.  
HIGH PRESSURE WILL THEN BUILD BACK ACROSS SOUTHERN CALIFORNIA FOR 
THIS WEEKEND AND EARLY NEXT WEEK...WITH DRY AND WARMER CONDITIONS 
DEVELOPING.  THE INLAND AREAS WILL SEE THE GREATEST WARMING...AS A 
SHALLOWER MARINE LAYER LINGERS ALONG THE COAST...AND CONTINUES TO 
MODIFY TEMPERATURES THERE.  ANOTHER MORE POTENT TROUGH OF LOW 
PRESSURE WILL THEN MOVE INLAND ACROSS THE WEST ON TUESDAY AND 
WEDNESDAY.  ANY MOISTURE ASSOCIATED WITH THIS TROUGH WILL STAY WELL 
TO OUR NORTH...BUT THE MARINE LAYER WILL DEEPEN AND BECOME MORE 
WIDESPREAD EACH NIGHT.  THE MOST NOTICEABLE DIFFERENCE WILL BE WITH 
OUR DAYTIME TEMPERATURES.  THE CURRENT MODEL RUNS ARE NOT QUITE AS 
COLD TODAY AS THEY WERE YESTERDAY...BUT DAYTIME TEMPERATURES WILL 
LIKELY FALL 5 TO 15 DEGREES BETWEEN MONDAY AND TUESDAY...BEFORE 
FALLING ANOTHER COUPLE OF DEGREES ON WEDNESDAY.  GUSTY WEST WINDS 
WILL ALSO DEVELOP IN THE MOUNTAINS AND DESERTS THESE DAYS...WITH 
BLOWING DUST OR SAND A POSSIBLE ISSUE.  AS THIS TROUGH SHIFT EAST ON 
THURSDAY AND FRIDAY...A TRANSITORY RIDGE WILL BRIEFLY REBUILD OVER 
THE REGION...WITH DRY AND WARMER CONDITIONS POSSIBLE.
