AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
243 AM PDT SAT MAR 28 2015

.SYNOPSIS...A WEAK PACIFIC DISTURBANCE WILL MOVE INTO THE REGION
TODAY AND SUNDAY...BRINGING SLIGHT COOLING AND BREEZY CONDITIONS
ALONG WITH A THREAT OF SHOWERS AND THUNDERSTORMS OVER THE SIERRA
CREST. TEMPERATURES WILL REMAIN SEVERAL DEGREES ABOVE NORMAL
THROUGH THE WEEKEND AND INTO NEXT WEEK.

&&

.DISCUSSION...
THE RIDGE OF HIGH PRESSURE OVER THE AREA THAT HELPED BRING RECORD
TEMPERATURES IN THE LOWER 90S TO THE SAN JOAQUIN VALLEY ON FRIDAY
IS SHIFTING EAST AND ALLOWING A WEAK TROUGH AND ASSOCIATED COLD
FRONT TO MOVE INTO CALIFORNIA. ALTHOUGH THE MARINE LAYER WAS ONLY
ABOUT 1500 FEET...THE APPROACHING TROUGH WAS ENOUGH TO HELP THE
MARINE AIR SPILL INTO THE SAN JOAQUIN VALLEY OVERNIGHT. THIS WILL
HELP COOL TEMPERATURES 5-10 DEGREES TODAY IN THE LOWER ELEVATIONS
WHILE THE HIGHER ELEVATIONS OF THE SIERRA SEE ONLY VERY SLIGHT
COOLING.

THE COLD FRONT DOES NOT HAVE MUCH MOISTURE WITH IT...BUT IT MAY
PROVIDE ENOUGH INSTABILITY OVER THE SIERRA NEVADA TO PRODUCE
A FEW SHOWERS OR EVEN A THUNDERSTORM. HAVE KEPT ONLY SLIGHT CHANCE
POPS FOR SATURDAY AND SUNDAY AFTERNOONS AND EVENINGS.

THE UPPER RIDGE WILL REBOUND ON MONDAY WITH TEMPERATURES WARMING
A FEW DEGREES. HOWEVER THE RIDGE WEAKENS AGAIN ON TUESDAY AS A
TROUGH OF LOW PRESSURE MOVES ACROSS THE PACIFIC NORTHWEST AND
BRINGS A MORE ZONAL FLOW ACROSS CENTRAL CALIFORNIA FOR TUESDAY AND
WEDNESDAY WITH ANOTHER WEAK SHORTWAVE MOVING ACROSS CALIFORNIA
THURSDAY. DO NOT EXPECT ANY PRECIPITATION WITH THESE WEAK SYSTEMS.
TEMPERATURES WILL REMAIN IN THE UPPER 70S TO NEAR 80 DEGREES IN
THE SAN JOAQUIN VALLEY FOR TUESDAY THROUGH THE END OF THE WEEK...
WHICH IS STILL SLIGHTLY ABOVE NORMAL.
