.SYNOPSIS...
HIGH PRESSURE CONTINUES TO BUILD OVER THE AREA RESULTING IN CLEAR
SKIES AND A GRADUAL WARMING TREND TO ABOVE NORMAL TEMPERATURES BY
EARLY NEXT WEEK.
&&
.DISCUSSION...
SEASONAL TEMPERATURES WILL CONTINUE ONE MORE DAY AS STRONG NW
FLOW CONTINUES OVER THE REGION. THIS IS ALSO PROVIDING WINDY
CONDITIONS BELOW THE TEHACHAPI PASS AND INTO MOJAVE. WE ARE
CURRENTLY KEEPING A WIND ADV UP THROUGH 5 AM AND WE EXPECT THE
WINDS TO START TO DIE OFF AS THE UPPER RIDGE BUILDS INTO THE
REGION TODAY WITH LIGHTER WINDS AND WARMER TEMPS. WE WILL SEE A
BIT OF A GRADIENT AS THE RIDGE WILL IMPACT VALLEY WINDS NEAR MCE
THIS AFTERNOON.
MODELS ARE STILL IN AGREEMENT WITH KEEPING TEMPS SLIGHTLY ABOVE
NORMAL THROUGH TUESDAY BEFORE A DIGGING TROUGH OF LOW PRESSURE
WILL MOVE INTO THE REGION AND COOL THINGS DOWN AGAIN LATE IN THE
WEEK. WE WILL ALSO SEE A RETURN OF GUSTY WINDS ACROSS THE SJV AND
INTO THE KERN DESERT AND BELOW THE PASSES. THIS SYSTEM WILL BE
SLOW TO MOVE OUT AS THE MAIN CENTER OF LOW PRESSURE WILL REMAIN
OVER THE PAC NW AS AN OMEGA BLOCKING PATTERN SETS UP OVER THE US
THURSDAY AND FRIDAY. CLOSED LOW CENTER OVER THE PAC NW WILL KEEP
ONSHORE FLOW OVER THE REGION WITH SEASONAL TEMPERATURES AND DRY
CONDITIONS INTO THE HOLIDAY WEEKEND.

.SYNOPSIS...
HIGH PRESSURE CONTINUES TO BUILD OVER THE AREA RESULTING IN CLEAR
SKIES AND A GRADUAL WARMING TREND TO ABOVE NORMAL TEMPERATURES BY
EARLY NEXT WEEK.
&&
.DISCUSSION...
A RIDGE OF HIGH PRESSURE REMAINS OVER THE EASTERN PACIFIC WHILE A
TROUGH OF LOW PRESSURE IS IN THE GREAT BASIN...LEAVING CENTRAL
CALIFORNIA IN A NORTHWESTERLY FLOW. ANOTHER SHORTWAVE DROPPING
ACROSS THE PACIFIC NORTHWEST INTO NEVADA IS PREVENTING THE RIDGE
FROM BUILDING INTO CALIFORNIA TODAY. IT IS ALSO KEEPING SFO-LAS
PRESSURE GRADIENT NEAR 12 MB THIS AFTERNOON...RESULTING IN A
CONTINUATION OF GUSTY WINDS BELOW THE TEHACHAPI PASS AND INTO THE
MOJAVE AREA. ALTHOUGH WINDS DROPPED BELOW ADVISORY CRITERIA THIS
MORNING AND EARLY AFTERNOON...EXPECT THEM TO INCREASE AGAIN BY
LATE AFTERNOON/EARLY EVENING AND CONTINUE TO BE GUSTY THROUGH THE
NIGHT. THUS THE WIND ADVISORY REMAINS IN EFFECT.
THE RIDGE WILL NUDGE EASTWARD SUNDAY AND MONDAY...WARMING
TEMPERATURES AND DECREASING THE WINDS. TEMPERATURES WILL REMAIN
ABOVE NORMAL THROUGH TUESDAY. ANOTHER TROUGH OF LOW PRESSURE WILL
DROP INTO THE PACIFIC NORTHWEST TUESDAY THEN DROP SOUTH INTO
CALIFORNIA WEDNESDAY AND REMAIN OVER THE REGION THROUGH THE
REMAINDER OF THE WEEK. THIS SYSTEM DOES NOT APPEAR TO HAVE ANY
MOISTURE SOURCE BUT WILL LIKELY BRING BREEZY TO WINDY CONDITIONS
ACROSS THE CWFA. IT WILL ALSO BRING COOLER TEMPERATURES
WEDNESDAY...WITH TEMPERATURES SLIGHT BELOW NORMAL WEDNESDAY
THROUGH FRIDAY. ALTHOUGH THERE ARE DIFFERENCES IN THE
DETAILS...THE GFS AND ECMWF ARE IN GENERAL AGREEMENT THAT A TROUGH
WILL BE HANGING AROUND THE REGION THROUGH THE MEMORIAL DAY
WEEKEND.

SEASONAL TEMPERATURES. A GRADUAL WARMING TREND TO ABOVE NORMAL
TEMPERATURES IS EXPECTED BY EARLY NEXT WEEK BEFORE ANOTHER SYSTEM
MOVES THROUGH TO COOL US DOWN AGAIN IN THE MIDDLE OF NEXT WEEK.
&&
.DISCUSSION...
GRADIENTS HAVE STAYED UP ACROSS THE REGION WITH LOCALIZED GUSTY
CONDITIONS JUST BELOW THE TEHACHAPI PASS AND AROUND MOJAVE. WE
HAVE EXTENDED THE WIND ADV UNTIL SUNDAY AM. THERE WILL BE A LULL
THIS AM AND THEN WE ARE EXPECTING THE WINDS TO PICK UP ONCE AGAIN
THIS AFTERNOON AND EVENING. TEMPS WERE UP A FEW DEGREES YESTERDAY
AND WE ARE EXPECTING THE SAME TODAY AS CLEAR SKIES AND NW FLOW
ALOFT WILL CONTINUE.
THE TROUGH IS SLOW TO MOVE EAST AND ANOTHER WEAK S/W WILL DROP
INTO THE PAC NW LATE TONIGHT AND INTO SUN THAT WILL SLOW DOWN THE
WARM UP EVEN MORE AS H5 HEIGHTS AND H850 TEMPS REMAIN STEADY
THROUGH MONDAY. WE WILL SEE TEMPS ONCE AGAIN RISE ABOVE NORMAL
MON AND TUESDAY. ANOTHER TROUGH OF LOW PRESSURE IS FORECAST TO
SWEEP INTO THE REGION ON WED AND APPEARS TO BE DRY AND WE CONTINUE
TO LEAVE THE FA DRY FOR NOW. HOWEVER THIS SYSTEM LOOKS TO BE
ANOTHER WIND EVENT FOR THE AREA AND HAVE INCREASED WINDS ON

DESERT IN THE MOJAVE AREA UNTIL MIDNIGHT TONIGHT AS SURFACE
PRESSURE GRADIENTS REMAIN STEADY. WINDY CONDITIONS ARE EXPECTED TO
CONTINUE WITH LOCAL GUSTS AROUND 50 MPH NEAR AND JUST ABOVE
MOJAVE ALONG HWY 58.

VICINITY OF MOJAVE.
PLENTY OF CLOUDS HAVE LINGERED OVER THE SIERRA TODAY. NO SHOWER
ACTIVITY YET THIS AFTERNOON...BUT A SLIGHT CHANCE OF SHOWERS
REMAINS THROUGH THE EARLY EVENING. OTHERWISE EXPECT SKIES TO
GRADUALLY CLEAR OVER THE MOUNTAINS TONIGHT WITH MOSTLY CLEAR SKIES
ELSEWHERE.
A RIDGE OF HIGH PRESSURE WILL BUILD INTO THE REGION OVER THE
WEEKEND. THIS WILL BRING A WARMING TREND THROUGH MONDAY.
TEMPERATURES THAT ARE SLIGHTLY BELOW NORMAL TODAY WILL WARM BACK
INTO THE LOWER 90S IN THE SAN JOAQUIN VALLEY ON MONDAY.
HOWEVER...THE WARM-UP WILL BE SHORT-LIVED AS A LOW PRESSURE SYSTEM
BEGINS TO AFFECT THE REGION BY THE MIDDLE OF NEXT WEEK. THE LOW
WILL MOVE INTO THE PACIFIC NORTHWEST TUESDAY...WEAKENING THE RIDGE
OVER CALIFORNIA AND INCREASING WINDS. THE TROUGH OF LOW PRESSURE
WILL TAKE UP RESIDENCE ALONG THE WEST COAST FOR THE REMAINDER OF
NEXT WEEK. THIS WILL RESULT IN TEMPERATURES COOLING NEARLY 10
DEGREES FROM TUESDAY TO WEDNESDAY AND THEN REMAINING COOL FOR THE
REMAINDER OF THE WEEK. THERE IS NOT MUCH MOISTURE WITH THIS
SYSTEM...SO NO PRECIPITATION IS EXPECTED ACROSS CENTRAL
CALIFORNIA.
THE 12Z ECMWF BEGINS TO LIFT THE LOW NORTHEAST AND OUT OF

NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
934 AM PDT FRI MAY 17 2013
.UPDATE...ADJUSTED POPS AND SKY COVER FOR TODAY AND TONIGHT.
&&
.SYNOPSIS...
HIGH PRESSURE WILL BUILD IN OVER THE AREA THROUGH THE WEEKEND WITH
SEASONAL TEMPERATURES. ISOLATED SHOWERS ARE POSSIBLE OVER THE HIGH
COUNTRY OF THE SIERRA TODAY. GRADUAL WARMING TREND TO ABOVE NORMAL
TEMPERATURES EARLY NEXT WEEK BEFORE ANOTHER SYSTEM MOVES THROUGH TO
COOL US DOWN AGAIN IN THE MIDDLE OF NEXT WEEK.
&&
.DISCUSSION...
THE TROUGH AXIS IS SHIFTING EAST THIS MORNING. SOME CLOUDS REMAIN
OVER THE MOUNTAINS AND THE SOUTH END OF THE SAN JOAQUIN
VALLEY...OTHERWISE THE REST OF THE CWFA IS CLEAR. SOME CUMULUS MAY
DEVELOP IN THE VALLEY LATER THIS MORNING...BUT NOT AS MUCH AS THE
FORECAST INDICATED...SO ADJUSTED SKY COVER DOWN TO BETTER DEPICT
WHAT IS HAPPENING. THERE IS STILL ENOUGH LINGERING INSTABILITY IN
THE SIERRA TO KEEP A SLIGHT CHANCE OF SHOWERS TODAY...BUT REMOVED
POPS FROM THE FOOTHILLS AND KERN COUNTY MOUNTAINS. WILL STILL HAVE
SOME BREEZY CONDITIONS TODAY ON THE BACK SIDE OF THE TROUGH...BUT
WILL STAY BELOW ADVISORY LEVELS. THE ONLY EXCEPTION IS AT MOJAVE
THIS MORNING WHERE WINDS HAVE BEEN GUSTING TO NEAR 45 MPH. DO NOT
EXPECT THE WINDS TO GET ANY STRONGER IN THIS AREA TODAY.
TODAY WILL BE ANOTHER COOL DAY WITH TEMPERATURES A FEW DEGREES
BELOW NORMAL. WARMING BEGINS AGAIN SATURDAY WITH SAN JOAQUIN
VALLEY TEMPERATURES CLIMBING BACK INTO THE 90S MONDAY AS HIGH
PRESSURE BUILDS BACK INTO THE REGION.
&&
.AVIATION...
LOCAL MVFR CEILINGS CAN BE EXPECTED ALONG THE WEST SLOPES OF
THE SIERRA NEVADA AND THE TEHACHAPI MOUNTAINS UNTIL 03Z SATURDAY.
OTHERWISE...VFR CONDITIONS WILL PREVAIL ACROSS THE CENTRAL CA
INTERIOR.
&&
.PREV DISC... /ISSUED 255 AM PDT FRI MAY 17 2013/
DISCUSSION...
FRONT HAS MOVED THROUGH THE REGION AND COOLER AIR HAS MOVED IN.
TEMPS YESTERDAY WERE SOME 15 TO 20 DEGREES COOLER THAN THE DAY
BEFORE. WE WILL CONTINUE TO SEE BELOW NORMAL TEMPS AGAIN TODAY
WITH SOME CLOUD COVER ALONG THE EAST AND SOUTH END OF THE VALLEY
AND ACROSS THE SIERRA. WE MAY EVEN SEE AN ISOLATED SHOWER OVER THE
HIGH COUNTRY OF THE SIERRA THIS AFTERNOON AS THE UPPER LEVEL
SYSTEM MOVES THROUGH WITH COLD AIR ALOFT. LAPSE RATES ARE NOT
IMPRESSIVE ENOUGH TO SUPPORT THUNDER IN THE SIERRA TODAY AS WE ARE
ONLY LOOKING FOR A SHOWER OR TWO AND POSSIBLE FLURRY ALONG THE
CREST WITH LITTLE OR NO ACCUM POSSIBLE AS MOISTURE IS VERY
LIMITED. SNOW LEVELS ARE EXPECTED TO BE ABOVE 8000 FEET TODAY.
EPAC SFC HIGH PRESSURE RIDGE WILL BUILD IN FROM THE WEST OVER THE
WEEKEND WITH A GRADUAL WARMING TREND TO AROUND NORMAL TEMPERATURES
FOR THIS TIME OF THE YEAR ON SATURDAY. SUNDAY THROUGH TUESDAY
WILL BE WARM AGAIN WITH THE WARMEST DAY ON MONDAY. SOME AREAS IN
THE SJV AND KERN DESERT WILL BE BACK INTO THE LOWER 90S. IT WILL
BECOME DRY AGAIN AND CONTINUED FIRE CONCERNS WILL REMAIN ACROSS
THE REGION AS TEMPS WARM UP AGAIN ABOVE NORMAL SUNDAY THROUGH
TUESDAY WITH LOWER RH VALUES. WINDS WILL BE LIGHT AS THE HIGH
PRESSURE CENTER INFLUENCES OUR WEATHER PATTERN.
STRONG COLD FRONT DROPPING SOUTH FROM THE GULF OF ALASKA WILL MOVE
THROUGH THE AREA ON WED WITH INCREASED WINDS AND A RETURN OF NEAR
TO JUST BELOW NORMAL TEMPERATURES. THIS LOOKS TO BE A DRY SYSTEM
AND WE ARE NOT INCLUDING ANY POPS FOR THE SIERRA ON WED AND
THURSDAY AT THIS TIME. WINDS WILL BE THE CONCERN WITH THIS EVENT
AS PRESS GRADS WILL INCREASE AS SRN NV LOW CENTER RAPIDLY DEVELOPS
AND DECENT UPPER JET BECOMES MORE IN LINE WITH SFC FLOW. H5
HEIGHTS AND 1000-850 MB THICKNESS VALUES SUPPORT TEMPS JUST BELOW
NORMAL AND BIAS CORRECTED GUIDANCE IS ALSO INDICATING A COOL DOWN
LATE NEXT WEEK BEHIND THE FRONT.

.UPDATE...
EXPIRED THE WIND ADVISORY FOR THE WEST CENTRAL SAN JOAQUIN VALLEY.
&&
.SYNOPSIS...
CLOUDS...WIND...AND LIGHT SHOWERS WILL CONTINUE TO MOVE ACROSS THE
REGION THROUGH FRIDAY. TEMPERATURES WILL REBOUND BY THE WEEKEND.
&&
.DISCUSSION...
WINDS THROUGH THE PACHECO PASS HAVE DIMINISHED...SO HAVE ALLOWED
THE WIND ADVISORY FOR THE WEST CENTRAL SAN JOAQUIN VALLEY TO
EXPIRE.
RADAR AND SATELLITE LOOPS SHOW A MOSTLY DRY FRONTAL BAND MOVING
THROUGH THE KERN COUNTY MOUNTAINS AND DESERTS AT THIS TIME. THIS
BAND HAS GENERATED A FEW GUSTS IN EXCESS OF 45 MPH...SO WILL
KEEP THE WIND ADVISORIES FOR THE KERN COUNTY MOUNTAINS AND DESERTS
IN PLACE FOR NOW.
&&
.AVIATION...
LOCAL MVFR CONDITIONS PERSISTING OVER THE CENTRAL SAN JOAQUIN
VALLEY AND INTO THE SOUTHERN SIERRA NEVADA AND TEHACHAPI RANGE
WITH PATCHES OF MTN OBSCURING IFR CONDITIONS IN SHOWERS. THESE
CONDITIONS WILL BE POSSIBLE THROUGH 07Z FRIDAY. GUSTY WINDS
CONTINUING...ESPECIALLY IN THE VICINITY OF MOUNTAIN PASSES THROUGH
07Z FRIDAY.
&&
.PREV DISC... /ISSUED 325 PM PDT THU MAY 16 2013/
DISCUSSION...
AN UPPER LEVEL WEAK COLD FRONT HAS MOVED SOUTHWARD THROUGH CENTRAL
CALIFORNIA TODAY BRINGING SCATTERED LIGHT SHOWERS TO THE AREA. THE
FRONT IS CURRENTLY ORIENTATED FROM THE NORTHEAST TO THE SOUTHWEST
OVER KERN COUNTY. THE UPPER LEVEL FLOW AHEAD OF AND PARALLEL TO THE
FRONT IS BRINGING STRONG WINDS TO THE TEHACHAPI MOUNTAIN AND KERN
COUNTY DESERT AREAS. WIND GUSTS ARE IN CURRENTLY IN THE MID 40 MPH
RANGE AT THIS TIME. A WIND ADVISORY UNTIL MIDNIGHT PDT IS
CURRENTLY IN EFFECT FOR THOSE LOCALES.
THE POST FRONTAL ONSHORE FLOW ASSOCIATED WITH THE TROUGH IS NOW
BEGINNING TO DEVELOP OVER THE CENTRAL CALIFORNIA COAST. THIS
ONSHORE FLOW WILL ALLOW FOR A MARINE PUSH AND BRING COOLER AIR
AND BREEZY CONDITIONS INTO THE SAN JOAQUIN VALLEY THIS
EVENING...ESPECIALLY IN THE PACHECO PASS AREA. THEREFORE...A WIND
ADVISORY WAS ISSUED AND WILL BE IN EFFECT THIS EVENING UNTIL 8 PM
PDT FOR THE WESTERN SIDE OF THE NORTHWESTERN SAN JOAQUIN VALLEY.
THE WESTERLY FLOW ALOFT COUPLED WITH THE COOLER AIRMASS...WILL
CREATE SOME OROGRAPHIC LIFT AND VERTICAL INSTABILITY THIS EVENING
AND OVERNIGHT HOURS WHICH WILL INCREASE THE CHANCES FOR A LIGHT
RAIN SHOWERS ALONG THE WEST SIDE OF THE SOUTHERN SIERRA RANGE
AND THE CREST AREAS. A FEW SHOWERS OVER THE SAN JOAQUIN VALLEY
CANNOT BE RULED OUT SINCE THE COOLING TEMPERATURES WILL RAISE THE
RELATIVE HUMIDITIES ALLOWING ANY DEVELOPING SHOWERS TO REACH THE
GROUND. ANY SHOWERS IN THE VALLEY WILL NOT AMOUNT TO MUCH.
RIDGING WILL BEGIN TO MOVE INTO THE REGION BY LATE FRIDAY AND
EARLY SATURDAY HOURS BRINGING GRADUALLY WARMING TEMPERATURES AND
CLEARING CONDITIONS. TEMPERATURES WILL BE BACK TO ABOVE NORMAL BY
SUNDAY LASTING THROUGH TUESDAY AFTERNOON WHEN ANOTHER PACIFIC
NORTHWEST SYSTEM BEGINS TO TRANSIT SOUTHWARD AGAIN LOWERING HEIGHTS
AND AGAIN INCREASING THE CLOUD COVER AND RAIN SHOWER CHANCES FOR THE
NORTHERN PARTS OF THE CWA.
