AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
305 AM PDT FRI MAY 24 2013

.SYNOPSIS...
LOW PRESSURE OVER THE PACIFIC NORTHWEST IS BRINGING A COOL ONSHORE
FLOW TO THE CENTRAL CALIFORNIA INTERIOR. TEMPERATURES WILL REMAIN
NEAR NORMAL THROUGH EARLY NEXT WEEK.


&&

.DISCUSSION...
OMEGA BLOCKING PATTERN CONTINUES OVER THE US ATTM AS CLOSED LOW
CENTER REMAINS NEARLY STATIONARY OVER THE PAC NW. MODELS ARE
KEEPING THE REGION DRY THROUGH SUNDAY WITH SEASONAL TEMPS
CONTINUING. SOME CHANGES HAVE TAKEN PLACE WITH THE GFS AND THE
TROUGH EXPECTED TO MOVE THROUGH ON MONDAY EVENING AND INTO TUESDAY.

WE HAVE BUMPED UP POPS MONDAY AND TUESDAY AS A STRONG TROUGH OF
LOW PRESSURE IS EXPECTED TO MOVE THROUGH THE AREA. THE ECM IS
TRYING TO CLOSE THE LOW CENTER AS IT DIVES SOUTH OVER US. THE ECM
IS ALSO SIGNIFICANTLY WETTER THAN THE GFS FOR MONDAY AND TUES. WE
ARE TAKING A BLEND OF THE MODELS AND LEANING MORE TOWARDS THE MORE
ROBUST ECM.

THE CNRFC AND HPC QPF VALUES ARE UP AND WE HAVE LOADED THEM AND
ADJUSTED POPS ACCORDINGLY. THE TROUGH MOVES THROUGH PRETTY QUICK
AND KEEP US IN A STRONG NW FLOW THROUGH NEXT WEEK WHICH WILL KEEP
THE TEMPS IN CHECK AS COOL ONSHORE FLOW WILL PREVAIL. SOME
ISOLATED SHOWERS ARE POSSIBLE IN THE HIGH COUNTRY AND AFTERNOON
CUMULUS DEVELOPMENT.

BREEZY CONDITIONS ARE EXPECTED IN THE VALLEY AND KERN COUNTY
DESERT REGIONS AS NW FLOW CONTINUES TODAY. WE MAY SEE SOME GUSTS
TO 40 MPH...NEAR AND BELOW THE KERN CO MOUNTAIN PASSES. WE MAY
ALSO SEE SOME GUSTS TO 25 MPH NEAR THE PACHECO PASS AND TOWARDS
