AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
112 PM PDT WED MAY 27 2015

.SYNOPSIS...
WARMING TEMPERATURES AND MOSTLY CLEAR SKIES WILL PERSIST FOR THE
NEXT SEVERAL DAYS AS HIGH PRESSURE CONTINUES TO DOMINATE THE REGION.

&&

.DISCUSSION...
SATELLITE IMAGERY SHOWS AN UPPER LOW OVER THE PACIFIC NORTHWEST
MOVING INTO IDAHO AND ANOTHER WEAK LOW MOVING ACROSS NORTHERN
BAJA INTO ARIZONA. IN BETWEEN...CENTRAL CALIFORNIA HAS MAINLY
CLEAR SKIES WITH A RIDGE OF HIGH PRESSURE JUST OFF THE WEST COAST.

THE HIGH RESOLUTION MODELS CONTINUE TO INDICATE ENOUGH INSTABILITY
TO GENERATE SOME CUMULUS BUILDUPS AND POSSIBLY A SHOWER OR
THUNDERSTORM ALONG THE CREST OF THE SIERRA THIS AFTERNOON AND
AGAIN THURSDAY AFTERNOON.

ENSEMBLES REMAIN CONSISTENT IN SHIFTING THE LOWS EASTWARD THIS
AFTERNOON AND TONIGHT ALLOWING THE RIDGE TO BEGIN BUILDING INLAND.
THIS WILL BRING WARMING TEMPERATURES ACROSS THE REGION THROUGH
SATURDAY. HIGHS ARE EXPECTED TO BE AROUND 9-12 DEGREES ABOVE
CLIMO BY SATURDAY. MID TO UPPER 90S WILL WIDESPREAD ACROSS THE SAN
JOAQUIN VALLEY...SIERRA FOOTHILLS AND THE DESERT AREAS FRIDAY AND
SATURDAY WITH A FEW AREAS REACHING AROUND 100 DEGREES SATURDAY
AFTERNOON.

HIGH CONFIDENCE CONTINUES IN THE RIDGE SHIFTING EASTWARD OVER THE
ROCKIES SUNDAY AS AN UPPER TROUGH APPROACHES FROM THE EASTERN
PACIFIC. A FEW DEGREES COOLING IS EXPECTED SUNDAY THEN MORE
SIGNIFICANT COOLING MONDAY AS THE TROUGH SWINGS INLAND.
TEMPERATURES ARE FORECAST TO DROP BACK TO AROUND SEASONAL LEVELS
EARLY NEXT WEEK. SURFACE PRESSURE GRADIENTS WILL RAMP UP AGAIN
SUNDAY PRODUCING BREEZY TO GUSTY WINDS...ESPECIALLY THROUGH AND
BELOW MOUNTAIN PASSES. THESE WINDS WILL LIKELY CONTINUE THROUGH AT
LEAST TUESDAY AS ADDITIONAL ENERGY ROUNDS THE TROUGH.


&&

.AVIATION...
ISOLATED SHOWERS AND THUNDERSTORMS POSSIBLE ACROSS THE SIERRA
NEVADA UNTIL 03Z THU. OTHERWISE...VFR CONDITIONS WILL PREVAIL
DURING THE NEXT 24 HOURS.

.AIR QUALITY ISSUES...
NONE.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
338 AM PDT WED MAY 27 2015

.SYNOPSIS...
A WARMING TREND WILL CONTINUE OVER CENTRAL CALIFORNIA THROUGH THE
END OF THE WEEK...WITH TEMPERATURES BECOMING SEVERAL DEGREES ABOVE
NORMAL. OTHERWISE...THE REGION WILL REMAIN DRY...EXCEPT OVER THE
SOUTHERN SIERRA NEVADA WHERE AFTERNOON SHOWERS AND THUNDERSTORMS
WILL BE POSSIBLE THROUGH THURSDAY.

&&

.DISCUSSION...SATELLITE IMAGERY SHOWS AN UPPER LOW SPINNING OVER
THE PACNW AND ANOTHER WEAK LOW OFF THE NORTHERN BAJA CA COAST.
A FEW HIGH CLOUDS ARE PASSING OVER KERN COUNTY ASSOCIATED WITH
THE LOW TO THE SOUTH. THESE WILL MOVE OFF TO THE EAST THROUGH
THE EARLY MORNING LEAVING ABUNDANT SUNSHINE IN STORE FOR TODAY.
A MODERATE ONSHORE SURFACE FLOW CONTINUES...WHICH BROUGHT IN SOME
COOLER MARINE AIR TO THE SAN JOAQUIN VALLEY LAST NIGHT RESULTING
IN SLIGHTLY LOWER TEMPERATURES TUESDAY THAN MONDAY. UPPER RIDGING
REMAINS OFFSHORE BUT IS POISED TO TRANSITION INLAND THE NEXT FEW
DAYS.

MINIMAL TSTORM ACTIVITY WAS OBSERVED TODAY...WITH JUST AN ISOLATED
CELL AROUND MT WHITNEY. THE HIGH RES MODELS SHOW INSTABILITY WILL
BE SUFFICIENT TO CONTINUE WITH A SLIGHT CHANCE ALONG THE CREST OF
THE SIERRA FOR THE NEXT COUPLE DAYS.

ENSEMBLES REMAIN CONSISTENT IN SHIFTING THE LOWS EASTWARD TODAY
ALLOWING THE RIDGE TO BEGIN BUILDING OVER THE WEST COAST IN THEIR
WAKE. THE WARMING TREND RESUMES TODAY WITH THE LOWER ELEVATIONS
EXPECTED TO CLIMB TO THE UPPER 80S TO LOWER 90S...A LITTLE ABOVE
CLIMO. THE RIDGE WILL CONTINUE TO DOMINATE THE PATTERN WITH THE
AXIS SHIFTING OVER CALIFORNIA FRI-SAT. FURTHER SYNOPTIC WARMING
WILL BRING ANOTHER 2-4 DEGREE RISE IN TEMPS EACH DAY THROUGH SAT.
HIGHS ARE EXPECTED TO BE AROUND 9-12 DEGREES ABOVE CLIMO SATURDAY
WITH SOME PARTS OF THE SJV AND DESERT FORECAST TO TOP OUT AROUND
THE CENTURY MARK.

HIGH CONFIDENCE CONTINUES IN THE RIDGE SHIFTING OVER THE ROCKIES
SUNDAY AS AN UPPER TROUGH APPROACHES FROM THE EPAC. A FEW DEGREES
COOLING IS EXPECTED SUNDAY THEN MORE SIGNIFICANT COOLING MONDAY
AS THE TROUGH SWINGS INLAND. SO THE TRIPLE DIGITS ARE EXPECTED TO
BE SHORT LIVED AS TEMPERATURES ARE FORECAST TO DROP BACK TO AROUND
SEASONAL LEVELS EARLY NEXT WEEK. SURFACE PRESSURE GRADIENTS WILL
RAMP UP AGAIN SUNDAY PRODUCING BREEZY TO GUSTY WINDS...ESPECIALLY
THROUGH AND BELOW MOUNTAIN PASSES. THESE WINDS WILL LIKELY CONTINUE

.DISCUSSION...
SATELLITE LOOPS SHOW AN UPPER LOW DROPPING THROUGH THE PACIFIC
NORTHWEST WHILE ANOTHER LOW PRESSURE CENTER OFF THE SOUTHERN
CALIFORNIA COAST DRIFTS EASTWARD TOWARD NORTHERN BAJA.
MEANWHILE...A WEAK SHORTWAVE IMPULSE IS MOVING EAST AWAY FROM
THE GREAT BASIN AREA. AMIDST ALL THIS SITS CENTRAL CALIFORNIA
WITH SOME CONVECTIVE CLOUDS DEVELOPING OVER THE SIERRA
ZONES...INCLUDING A FEW SHOWERS NEAR THE CREST. OTHERWISE...JUST
SOME THIN HIGH CLOUDINESS DRIFTING OVER THE REMAINDER OF OUR AREA.
INCREASED ONSHORE SURFACE PRESSURE GRADIENTS HAVE HELPED TO USHER
IN SOME COOLER AIR THROUGHOUT THE SAN JOAQUIN VALLEY WHERE 24 HR
TEMPERATURE TRENDS ARE CURRENTLY RUNNING DOWN AROUND 2-4 DEGREES.
HIGHER ELEVATIONS ARE GENERALLY EXPERIENCING A COUPLE OF DEGREES
OF WARMING WHILE LITTLE CHANGE IS NOTED IN DESERT AREAS THIS
AFTERNOON.

MODELS ARE CONSISTENT IN THEIR DEPICTION OF THE EVOLVING SYNOPTIC
PATTERN...SHOWING A BUILDING RIDGE OVER THE REGION BEHIND THE
EXITING LOW PRESSURE SYSTEMS. THIS WILL BRING A WARMING TREND
THROUGH THE END OF THE WEEK...WITH TEMPERATURES CLIMBING FROM
NEAR CLIMO TODAY TO AROUND 10 DEGREES ABOVE BY SATURDAY...WHEN A
FEW OF THE WARMER SAN JOAQUIN VALLEY AND DESERT LOCATIONS COULD
REACH TRIPLE DIGITS. A FEW THUNDERSTORMS WILL BE POSSIBLE NEAR THE
SIERRA CREST DURING THE NEXT COUPLE OF AFTERNOONS AHEAD OF THE
BUILDING RIDGE.

THE FIRST PART OF NEXT WEEK WILL SEE COOLING TEMPERATURES AS
MODELS ARE IN REASONABLE AGREEMENT SHOWING A DEVELOPING TROUGH
MOVING INTO THE CALIFORNIA COAST. THIS WILL DROP TEMPERATURES BACK
TO AT OR EVEN SLIGHTLY BELOW SEASONAL AVERAGES BY TUESDAY. LITTLE
ASSOCIATED MOISTURE IS PROGGED WITH THIS TROUGH AND NO PRECIPITATION

307 AM PDT TUE MAY 26 2015

.SYNOPSIS...A WARMING TREND WILL OCCUR OVER CENTRAL CALIFORNIA
THROUGH THE END OF THE WEEK...WITH TEMPERATURES BECOMING ABOVE
NORMAL. OTHERWISE...THE REGION WILL REMAIN DRY...EXCEPT OVER THE
SOUTHERN SIERRA NEVADA WHERE AFTERNOON SHOWERS AND THUNDERSTORMS
WILL BE POSSIBLE THROUGH THURSDAY.

&&

.DISCUSSION...AMPLIFIED OFFSHORE UPPER RIDGE THAT HAS BEEN SLOWLY
PUSHING INLAND INTO CA IS PROVIDING OUR AREA WITH A NOTICABLE
WARMING TREND AS DAYTIME TEMPERATURES ON MEMORIAL DAY WERE CLOSE
TO SEASONAL NORMALS FOR LATE MAY ACROSS OUR AREA. MEANWHILE...A
WEAK SYSTEM DROPPING THROUGH THE GREAT BASIN OVERNIGHT HAS
PROVIDED FOR INCREASED ONSHORE P-GRADS RESULTING IN SOME LOCALLY
GUSTY WINDS ACROSS THE WEST SIDE OF THE SAN JOAQUIN VALLEY. WITH
GRADIENTS NOW DECREASING...WINDS WILL DECREASE TOWARD MORNING AND
WE THEREFORE DO NOT ANTICIPATE THE ISSUANCE OF ANY WIND HIGHLIGHTS
THIS MORNING...ALTHOUGH LOCAL GUSTS TO NEAR 35 MPH WILL BE
POSSIBLE ALONG THE WEST SIDE OF THE SAN JOAQUIN VALLEY FOR A FEW
MORE HOURS.

06Z WRF INDICATING A DRY NORTHWEST FLOW WILL PREVAIL TODAY OVER
CENTRAL CA KEEPING MOST OF OUR AREA DRY UNDER MAINLY CLEAR SKIES.
THE HRRR IS INDICATING ISOLATED SHOWERS THIS AFTERNOON OVER THE
HIGHER ELEVATIONS OF THE SOUTHERN SIERRA NEVADA AND THE WRF IS
INDICATING CAPES AND LI/S WILL BE SUFFICIENT FOR THUNDERSTORMS
NEAR THE CREST SO SO WILL CONTINUE TO MENTION A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS FOR THE HIGHER ELEVATIONS OF THE
SOUTHERN SIERRA NEVADA FOR THIS AFTERNOON AND EVENING.

IR IMAGERY IS INDICATING AN UPPER LOW CENTER NEAR 31N/132W
WHICH MAY SPREAD SOME HIGH CLOUDS INTO OUR AREA TONIGHT AND

NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
307 AM PDT TUE MAY 26 2015

.SYNOPSIS...A WARMING TREND WILL OCCUR OVER CENTRAL CALIFORNIA
THROUGH THE END OF THE WEEK...WITH TEMPERATURES BECOMING ABOVE
NORMAL. OTHERWISE...THE REGION WILL REMAIN DRY...EXCEPT OVER THE
SOUTHERN SIERRA NEVADA WHERE AFTERNOON SHOWERS AND THUNDERSTORMS
WILL BE POSSIBLE THROUGH THURSDAY.

&&

.DISCUSSION...AMPLIFIED OFFSHORE UPPER RIDGE THAT HAS BEEN SLOWLY
PUSHING INLAND INTO CA IS PROVIDING OUR AREA WITH A NOTICABLE
WARMING TREND AS DAYTIME TEMPERATURES ON MEMORIAL DAY WERE CLOSE
TO SEASONAL NORMALS FOR LATE MAY ACROSS OUR AREA. MEANWHILE...A
WEAK SYSTEM DROPPING THROUGH THE GREAT BASIN OVERNIGHT HAS
PROVIDED FOR INCREASED ONSHORE P-GRADS RESULTING IN SOME LOCALLY
GUSTY WINDS ACROSS THE WEST SIDE OF THE SAN JOAQUIN VALLEY. WITH
GRADIENTS NOW DECREASING...WINDS WILL DECREASE TOWARD MORNING AND
WE THEREFORE DO NOT ANTICIPATE THE ISSUANCE OF ANY WIND HIGHLIGHTS
THIS MORNING...ALTHOUGH LOCAL GUSTS TO NEAR 35 MPH WILL BE
POSSIBLE ALONG THE WEST SIDE OF THE SAN JOAQUIN VALLEY FOR A FEW
MORE HOURS.

06Z WRF INDICATING A DRY NORTHWEST FLOW WILL PREVAIL TODAY OVER
CENTRAL CA KEEPING MOST OF OUR AREA DRY UNDER MAINLY CLEAR SKIES.
THE HRRR IS INDICATING ISOLATED SHOWERS THIS AFTERNOON OVER THE
HIGHER ELEVATIONS OF THE SOUTHERN SIERRA NEVADA AND THE WRF IS
INDICATING CAPES AND LI/S WILL BE SUFFICIENT FOR THUNDERSTORMS
NEAR THE CREST SO SO WILL CONTINUE TO MENTION A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS FOR THE HIGHER ELEVATIONS OF THE
SOUTHERN SIERRA NEVADA FOR THIS AFTERNOON AND EVENING.

IR IMAGERY IS INDICATING AN UPPER LOW CENTER NEAR 31N/132W
WHICH MAY SPREAD SOME HIGH CLOUDS INTO OUR AREA TONIGHT AND
WEDNESDAY AS IT TRACKS EAST OVER NORTHERN BAJA. OTHERWISE THIS
FEATURE WILL HAVE LITTLE IMPACT FOR OUR AREA. THE OFFSHORE RIDGE
IS PROGGED TO PUSH FURTHER INLAND ON WEDNESDAY AND THURSDAY
RESULTING IN RISES IN HEIGHTS AND DIURNAL THICKNESSES OVER OUR
AREA AND SUBSEQUENTLY DAYTIME TEMPERATURES WILL RISE TO ABOVE
NORMAL LEVELS. WRF PROGGED CAPES AND INSTABILITY ARE EXPECTED TO
DECREASE EACH DAY RESULTING IN LESS POTENTIAL FOR DIURNAL

A WARMING TREND WILL OCCUR OVER CENTRAL CALIFORNIA THROUGH THE END
OF THE WEEK...WITH TEMPERATURES BECOMING A FEW DEGREES ABOVE NORMAL.
OTHERWISE...THE REGION WILL REMAIN DRY...EXCEPT OVER THE SIERRA
NEVADA WHERE AFTERNOON SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
THROUGH THURSDAY.

&&

.DISCUSSION...NORTHWEST FLOW ALOFT CONTINUES ACROSS OVER CENTRAL
CALIFORNIA AS A LONG WAVE TROUGH COVERS THE WESTERN CONUS. UPPER
RIDGING WILL REMAIN JUST OFF THE COAST THROUGH MIDWEEK AS AN UPPER
LOW DROPS SOUTH FROM BRITISH COLUMBIA OVER THE PACNW. EXPECT SOME
MORE AFTERNOON SHOWERS AND POSSIBLY A FEW THUNDERSTORMS OVER THE
SOUTHERN SIERRA TODAY THROUGH THURSDAY. BY THEN THE LOW OVER THE
PACNW WILL HAVE OPENED UP AND SHIFTED OFF TO THE EAST...ALLOWING
THE EPAC RIDGE TO BUILD INLAND.

TEMPERATURES WILL GENERALLY WARM A FEW DEGREES TODAY IN THE LOWER
ELEVATIONS...WHERE SKIES WILL REMAIN SUNNY. THE AFOREMENTIONED LOW
WILL TEMPORARILY STALL WARMING ON TUESDAY AS IT DRIFTS A BIT FARTHER
SOUTH. BUT THE WARMING TREND STARTS UP AGAIN WEDNESDAY AND CONTINUES
THROUGH THE END OF THE WEEK AS THE RIDGE AXIS MOVES OVER CALIFORNIA.
THERE IS GOOD MODEL AGREEMENT WITH THE RIDGE THEN SHIFTING OVER THE
ROCKIES NEXT WEEKEND AS A PACIFIC TROUGH APPROACHES THE WEST COAST.
THE WARMEST DAYS LOOK TO BE FRIDAY AND SATURDAY WITH WIDESPREAD 90S
ACROSS THE SAN JOAQUIN VALLEY AND EASTERN KERN COUNTY DESERT. NORMAL
HIGHS FOR LATE MAY ARE GENERALLY IN THE UPPER 80S...AND SOME AREAS
MAY REACH THE UPPER 90S. EXPECT SOME COOLING BY NEXT SUNDAY AS THE
TROUGH NEARS THE COAST.

ONSHORE SURFACE FLOW CONTINUES TO PRODUCE BREEZY TO GUSTY CONDITIONS
THROUGH AND BELOW MOUNTAIN PASSES. WHILE THESE GUSTS ARE EXPECTED TO
REMAIN BELOW ADVISORY LEVEL...THERE IS POTENTIAL FOR SOME LOCALIZED
BLOWING DUST ACROSS THE WEST SIDE OF THE SAN JOAQUIN VALLEY THIS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
325 PM PDT SUN MAY 24 2015

.SYNOPSIS...
A WARMING TREND WILL TAKE PLACE OVER CENTRAL CALIFORNIA THROUGH THE
END OF NEXT WEEK...WITH TEMPERATURES SLIGHTLY ABOVE NORMAL BY THE
MIDDLE OF THE WORK WEEK. OTHERWISE...THE REGION WILL REMAIN
DRY...EXCEPT OVER THE SIERRA NEVADA WHERE THUNDERSTORMS WILL BE
POSSIBLE EACH AFTERNOON AND EVENING.

&&

.DISCUSSION...
NORTHWEST FLOW ALOFT DOMINATING THE REGION AS THE UPPER LOW NOW
SITS OVER SOUTHERN ARIZONA. THIS NORTHWEST FLOW IS ALLOWING FOR
MORE STABLE AND DRIER AIR TO FILTER INTO CENTRAL CALIFORNIA.
LATEST VISIBLE SATELLITE IMAGERY SHOWING RELATIVELY CLEAR SKIES
OVER MUCH OF THE DISTRICT WITH WEAK INSTABILITY CLOUDS FORMING
OVER THE HILLS. WHILE THE WIND SPEEDS ALOFT REMAIN HIGH OVER MUCH
OF THE AREA...WIND SPEED TREND WILL CONTINUE TO DECREASE OVER THE
NEXT 24 TO 48 HOURS. IN THE MEANWHILE...OROGRAPHIC LIFT WILL
SUPPORT THE WEAK INSTABILITY TO MAINTAIN A POSSIBLE CHANCE OF
THUNDERSTORMS OVER THE SIERRA NEVADA RANGE. YET...WILL KEEP
CHANCES AT SLIGHT CHANCE LEVELS.

THE FLOW ALOFT WILL BECOME MORE ZONAL ON MEMORIAL DAY AS A LOW
RIDES OVER THE EPAC RIDGE AND SITS OVER WESTERN CANADA. BY MID
WEEK...THE UPPER LOW OVER WESTERN CANADA WILL SLOW DRIFT INTO THE
INTER-MOUNTAIN WEST AS AN OMEGA BLOCK FORMS OVER THE WEST COAST.
MODELS SHOWING GOOD AGREEMENT WITH THIS POSSIBLE SOLUTION FOR THE
END OF REMAINDER OF THE WEEK. ENSEMBLE MODELS AND GFS MOD TREND
ANALYSIS STILL SHOWING HIGHER CONFIDENCE LEVELS WITH DEVELOPING A
RIDGE //BLOCKING// PATTERN BLOCKING OVER THE WEST COAST THROUGH
FRIDAY WITH SUNDAY BEING A TRANSITION PERIOD. UNCERTAINTY IS LOW
AS MODELS AGREE WITH THE FORMATION OF A RIDGE PATTERN THAT WILL
MOVE INTO THE GREAT BASIN BY SUNDAY. THEREFORE...SATURDAY WILL
SEE THE END OF THE WARMING TREND IN TEMP/S AS A COOL DOWN STARTS
ON SUNDAY. AT THIS POINT...WILL NOT INTRODUCE ANY CHANCES OF
PRECIP FOR NEXT WEEKEND...BUT WILL STILL TREND TOWARD THAT
POTENTIAL.

&&

.AVIATION...
AREAS OF MOUNTAIN OBSCURING IFR CONDITIONS IN SHOWERS AND ISOLATED
THUNDERSTORMS DEVELOPING ACROSS THE SIERRA NEVADA THROUGH 06Z MONDAY
AND AGAIN AFTER 18Z. OTHERWISE...VFR CONDITIONS WILL PREVAIL DURING
THE NEXT 24 HOURS.

&&

.AIR QUALITY ISSUES...
NONE.
