.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
LOS BANOS THIS AFTERNOON AS GRADIENTS INCREASE.

.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...
IN THE SHORT TERM...THE MAIN CONCERNS HAVE BEEN THE GUSTY
CONDITIONS IN THE KERN DESERT AND TEHACHAPI PASS AREAS AND THE
COOLER TEMPERATURES. WITH A NORTHWEST FLOW IN PLACE ABOVE US WINDS
ARE FLOWING OVER THE TEHACHAPI MOUNTAINS AND SINKING ON THE
EASTERN SLOPES MAKING FOR GUSTY CONDITIONS ESPECIALLY IN THE
MOJAVE AREA. A WIND ADVISORY IS IN EFFECT THERE UNTIL 9 PM THIS
EVENING BUT MY RELIEF WILL NEED TO MONITOR THE SITUATION FOR
POSSIBLY TEMPORALLY EXTENDING THE ADVISORY. AS FAR AS THE COOLER
TEMPERATURES GO THE SAN JOAQUIN VALLEY WILL AGAIN HAVE ANOTHER
COOL MORNING WITH LOWS IN THE MIDDLE TO UPPER 40S. WITH WINDS
VIRTUALLY NON EXISTENT TODAY COMPARED TO YESTERDAY MIXING WILL BE
MINIMIZED AND ALONG WITH MOSTLY CLEAR SKIES RADIATIONAL COOLING
WILL THEREFORE BE MAXIMIZED. SOME AREAS COULD POTENTIALLY FLIRT
WITH NEAR RECORD LOW TEMPERATURES.
TEMPERATURES WILL GRADUALLY AND SLIGHTLY BE ON AN UPWARD SWING
FOR THE REMAINDER OF THE WEEK AND OVER THE WEEKEND BUT WILL
CONTINUE TO REMAIN NEAR NORMAL. SKIES WILL ALSO REMAIN MOSTLY
CLEAR THROUGH THE WEEKEND. WITH AN OMEGA BLOCK FIRMLY IN PLACE
OVER THE CENTRAL U.S. A SYSTEM OVER THE PAC WEST WHICH HAS BEEN
SPINNING IN PLACE FOR THE LAST FEW DAYS WILL BEGIN TO MOVE
SOUTHWARD AND WILL INCREASE THE CLOUDS AND COOL TEMPERATURES
BEGINNING MONDAY. THE ONLY QUESTION IS WILL ANY PRECIPITATION
OCCUR. AT THIS TIME THE CURRENT THINKING IS THAT WITH LITTLE
ATMOSPHERIC MOISTURE PRESENT MEASURABLE PRECIPITATION WILL BE
UNLIKELY. HOWEVER...HAVING SAID THAT THERE WILL BE A GOOD CHANCE
FOR VERY LIGHT SPRINKLES ESPECIALLY FRESNO NORTHWARD MONDAY NIGHT
THROUGH TUESDAY. WITH SHORTWAVE IMPULSES MOVING THROUGH THE AREA
TEMPERATURES NEXT WEEK WILL REMAIN WELL WITHIN NORMAL RANGES AND
CLOUDS WILL BE MORE LIKELY.
&&

LOW PRESSURE AREA IS OVER THE PACIFIC NORTHWEST IS BRINGING A
COOL ONSHORE FLOW TO CENTRAL CALIFORNIA. TEMPERATURES WILL REMAIN
NEAR NORMAL THROUGH THE EARLY NEXT WEEK.
&&
.DISCUSSION...
DEEP UPPER LOW PRESSURE CENTER OVER THE PAC NW IS EXPECTED TO
REMAIN NEARLY STATIONARY THROUGH EARLY NEXT WEEK AS A SERIES OF
WEAK IMPULSES MOVE THROUGH THE MEAN NW FLOW OVER THE REGION. OMEGA
BLOCKING PATTERN OVER THE NORTHERN TIER OF THE US IS KEEPING THE
PATTERN STATIONARY THROUGH TUESDAY. STRONG ONSHORE FLOW OVER THE
REGION WILL KEEP TEMPS IN CHECK TO NEAR NORMAL THROUGH TUESDAY AND
WE HAVE IN A CHANCE OF SHOWERS ACROSS THE SIERRA ON TUESDAY AFTN
AND EVENING AS ANOTHER SIGNIFICANT TROUGH MOVES THROUGH THE
REGION. WE ARE PRETTY MUCH GOING WITH CLIMO POPS FOR THE SIERRA ON
TUESDAY.
GFS IS MUCH MORE AGGRESSIVE WITH THE TROUGH ON TUESDAY AND IS
BRINGING IN A CLOSED LOW CENTER ACROSS THE REGION WITH SIGNIFICANTLY
MORE PRECIP TO THE SIERRA. WE ARE NOT BUYING INTO THIS SOLN ATTM
AND ARE LEANING TOWARDS THE ECMWF DUE TO RUN TO RUN CONSISTENCY
AND IS MORE IN LINE WITH THE ENSEMBLE MEAN. THE ECMWF IS BRINGING
A TROUGH THROUGH THE REGION AND IS NOT AS AGGRESSIVE AS THE GFS.
H5 HEIGHTS REMAIN LOW THROUGH THE FORECAST PERIOD AND EXPECT TEMPS
TO REMAIN NEAR NORMAL OR JUST BELOW NORMAL THROUGH THE FORECAST
PERIOD. BREEZY CONDITIONS ARE EXPECTED TO CONTINUE THROUGH TONIGHT
AS ONSHORE FLOW CONTINUES AND WILL BE ESPECIALLY WINDY THROUGH AND
JUST BELOW THE KERN COUNTY MOUNTAIN PASSES NEAR MOJAVE. CHANNELING
THROUGH THE PACHECO PASS WILL ALSO BE A CONCERN..BUT ARE EXPECTED
TO REMAIN JUST BELOW ADV LEVELS OF GUSTS TO 35 MPH.

250 PM PDT WED MAY 22 2013
.SYNOPSIS...
AN UNSEASONABLY COOL LOW PRESSURE AREA IS OVER THE PACIFIC
NORTHWEST. THIS IS BRINGING A MUCH COOLER ONSHORE FLOW TO CENTRAL
CALIFORNIA...AND TEMPERATURES TODAY WILL BE SOME 10 TO 20 DEGREES
LOWER THAN YESTERDAY. LITTLE CHANGE IS EXPECTED THURSDAY...THEN A
VERY SLOW WARMING TREND INTO THE WEEKEND. HOWEVER IT NOW LOOKS LIKE
BELOW NORMAL TEMPERATURES WILL PREVAIL INTO EARLY NEXT WEEK.
&&
.DISCUSSION...
STRONG WINDS ACROSS THE CENTRAL CALIFORNIA INTERIOR CONTINUES AS
THE DOMINATE WEATHER FEATURE IN THE SHORT TERM. AN UPPER LOW
CENTERED OVER THE PACIFIC NORTHWEST HAS BEEN RESPONSIBLE FOR THE
WINDY CONDITIONS FOR THE LAST DAY FEW DAYS. AS THE LOW CONTINUES
TO SIT OVER THE NORTHWEST COAST...PIECES OF SHORT WAVE ENERGY
ROTATE AROUND THE LOW AND MOVE THROUGH NORTHERN/CENTRAL
CALIFORNIA. TODAY/S SHORT WAVE WAS ASSOCIATED WITH A JET MAX THAT
ALSO MOVED THROUGH THE REGION AND ALLOWED FOR A RUSH OF COOL
MARINE AIR TO SURGE INTO THE VALLEY. WITH THIS...TEMPERATURES
ACROSS THE SAN JOAQUIN VALLEY WERE SOME 10 TO 15 DEG-F COOLER THAN
THIS TIME ON TUESDAY. THE COOL AIR ALSO ALLOWED SURFACE PRESSURE
GRADIENT TO TIGHTEN DURING THE DAY. 24 HOUR CHANGE IN SURFACE
PRESSURE GRADIENTS FROM SFO TO LAS HAVE TIGHTEN BY 7MB FROM 10MB
YESTERDAY TO 17MB SO FAR THIS AFTERNOON. THEREFORE...A WIND
ADVISORY IS IN EFFECT FOR THE KERN COUNTY MTNS AND DESERTS THROUGH
5 AM THURSDAY FOR WINDS GUSTING TO 45 MPH. WHILE SAN JOAQUIN
VALLEY WINDS WERE ALSO VERY WINDY...SPEEDS HAVE BEEN LOWER THEN
THOSE OBSERVED OVER KERN COUNTY...YET...THE WINDS WERE LIFTING
DUST INTO THE VALLEY AIR. THEREFORE...THE SAN JOAQUIN VLY AIR
POLLUTION CONTROL DISTRICT HAS ISSUED A HEALTH CAUTIONARY STATEMENT
DUE TO BLOWING DUST.
AGAIN...THE UPPER LOW CONTINUES TO SIT NEAR THE NORTHWEST PACIFIC
COAST...AND WILL DO SO FOR THE NEXT TWO DAYS. WITH LITTLE CHANGE
IN THE WEATHER PATTERN...MAY SEE PERIODS OF STRONG WINDS ALONG
WITH LITTLE CHANGE IN TEMPERATURES. YET...WITH A CYCLONIC FLOW
PATTERN OVER THE WEST COAST...ANY WARMING WILL BE INHIBITED BY THE
COOLING OF ANOTHER PASSING SHORT WAVE TROF. THEREFORE...WILL KEEP
TEMPERATURES FOR MOST THE NEXT SEVEN DAYS AT OR BELOW NORMAL.
MODEL UNCERTAINTY INCREASES TOWARD DAY/S 6 AND 7. BOTH GFS/ECMWF
SHOW INCREASING ERROR IN BOTH AMPLITUDE AND TIMING AFTER THE
MONDAY PERIOD. WILL INTRODUCE A SLIGHT CHANCE OF PRECIP...MAINLY
OVER THE SIERRA NEVADA AND POSSIBLE NEAR MERCED COUNTY FOR TUESDAY
AND WEDNESDAY. WITH HIGH UNCERTAINTY...WILL KEEP PROB OF PRECIP TO
VALUES BELOW 30 PERCENT...EXCEPT FOR YOSEMITE...AND WAIT FOR
BETTER MODEL CONSENSUS BEFORE ADJUSTING THESE PERIODS.
&&

WIND GUSTS OF 35 KNOTS OR GREATER CAN BE EXPECTED ALONG THE
