AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
317 PM PDT THU APR 28 2016

.SYNOPSIS...
CLEARING SKIES AND WARMER TEMPERATURES NEXT SEVERAL DAYS AS WEAK
HIGH PRESSURE MOVES OVER THE REGION. HOWEVER, A WEAK SYSTEM WILL
BRUSH RETURN THE AREA SATURDAY BRINGING AN INCREASE IN CHANCES FOR
PRECIPITATION OVER THE HIGHER ELEVATIONS. ANOTHER WEATHER SYSTEM
POSSIBLE BY THE END OF NEXT WEEK.

&&

.DISCUSSION...
LOTS OF CLOUD COVER ACROSS THE SAN JOAQUIN VALLEY KEEPING
TEMPERATURES BELOW THE EXPECTED HIGHS. LOTS OF VARIANCE IN
TEMPERATURES WITH CLEARING SKIES IN THE NORTH AND WEST SECTORS OF
THE VALLEY WITH TEMPERATURES RISING INTO THE LOWER 70S. THE
ATMOSPHERE REMAINS UNSTABLE WITH PLENTY OF MOISTURE TO FUEL
SHOWERS AND THUNDERSTORMS. A FEW STORMS ARE DEVELOPING THIS
AFTERNOON OVER THE HIGH SIERRA. SOME LIGHT SHOWERS COULD DRIFT
INTO THE FOOTHILLS WITH A MODERATE NORTH WIND FLOW. OTHERWISE
EXPECT STORM ACTIVITY TO REMAIN IN THE SIERRA HIGH COUNTRY AND
QUICKLY DIMINISH AFTER SUNSET WITH THE LOSS OF DAYTIME HEATING
TRIGGER. MODELS SHOW MOISTURE POOLING TOWARDS THE NORTH FACING
SLOPES OF THE TEHACHAPIS AND SOUTH END OF THE VALLEY DUE TO THE
UPSLOPE WIND.

THE CENTER OF THE UPPER LOW EXTEND FROM SOUTHERN NEVADA SOUTH TO
THE COLORADO RIVER. THE LOW WILL DRIFT SLOWLY EAST TONIGHT
REACHING THE FOUR CORNERS AREA FRIDAY. MODELS PROG SUFFICIENT
MOISTURE AND INSTABILITY FOR ISOLATED SHOWERS OR A THUNDERSTORMS
FRIDAY AFTERNOON WITH DAYTIME HEATING AS THE MAIN TRIGGER.

ANOTHER SHORT WAVE QUICKLY DROPS DOWN FROM THE PACIFIC NW FRIDAY
NIGHT AND OVER SOCAL BY SATURDAY AFTERNOON. THIS WILL BRING
A GOOD CHANCE FOR MOUNTAIN SHOWERS OVER THE WEEKEND WITH A SLIGHT
CHANCE OVER THE DESERT. MODEL INSTABILITY INDICATE SOME ISOLATED
THUNDERSTORMS WILL BE POSSIBLE AS WELL. SHORT WAVE RIDGING BUILDS
IN MONDAY FOR DRY CONDITIONS THROUGH MIDWEEK. AN AMPLIFIED TROUGH
OVER THE EAST PACIFIC  MAY MOVE IN LATER IN THE WEEK FOR ANOTHER
CHANCE OF PRECIPITATION.

THE ONSHORE SURFACE PRESSURE GRADIENT WILL CONTINUE TO PRODUCE
SOME BREEZY CONDITIONS THIS EVENING WITH GUSTY WINDS THROUGH AND
BELOW THE KERN COUNTY MOUNTAIN PASSES. THE GRADIENT TURNS MORE
NORTH- SOUTH ON FRIDAY NIGHT WITH THE NEXT SYSTEM...BRINGING
INCREASED WINDS OVER THE SAN JOAQUIN VALLEY FRIDAY NIGHT THROUGH
SATURDAY.

TEMPERATURES WILL WARMING FRIDAY TO NEAR TO SLIGHTLY ABOVE NORMAL.
SLIGHT COOLING ARRIVES ON SATURDAY THEN WARMING THROUGH THE
MIDDLE OF NEXT WEEK WITH HIGHS CLIMBING TO SEVERAL DEGREES ABOVE
NORMAL.

NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
128 PM PDT WED APR 27 2016

.SYNOPSIS...
RAINSHOWERS AND THUNDERSTORMS WILL MOVE THROUGH CENTRAL CALIFORNIA
THIS AFTERNOON AND INTO THE EVENING. HEAVY
RAIN...LIGHTNING...GUDTYWINDS AND HAIL IS POSSIBLE WITH THE
THNDERSTORMS. WHEN THUNDER ROARS, GO INDOORS. SKIES WILL CLEAR BY
THURSDAY AS WEAK HIGH PRESSURE MOVES IN OVER THE REGION.

&&

.DISCUSSION...SATELLITE IMAGERY SHOWS THE CENTER OF THE INCOMING
LOW PRESSURE SYSTEM MOVING SOUTHEAST ACROSS WINE COUNTRY AND RADAR
INDICATES THE LEADING EDGE OF SHOWERS AND THUNDERSTORMS NOW
APPROACHING MERCED COUNTY FROM THE NORTHWEST. BASED ON TRAJECTORY
OF CURRENT ECHOES COMBINED WITH THE HIGH RESOLUTION RAPID REFRESH
MODEL`S HOURLY FORECASTS, THIS BAND OF PRECIPITATION WILL MOVE
SOUTHEAST ACROSS THE SAN JOAQUIN VALLEY PORTION OF THE FORECAST
AREA THIS AFTERNOON AND REACH KERN COUNTY BY LATE IN THE
AFTERNOON. MEANWHILE OVER THE SIERRA, AFTERNOON INSTABILITY IS ON
THE INCREASE DUE TO HEATING AND THE ADDED LIFT OF THE APPROACHING
SYSTEM. WINDS ARE BLOWING THROUGH THE TEHACHAPI PASS AND THE
ADJACENT MOJAVE AREA AND WILL CONTINUE THROUGH THE AFTERNOON AND
EVENING SO THE WIND ADVISORY WILL REMAIN IN PLACE.

EXPECT SCATTERED THUNDERSTORMS THROUGH THE EVENING AS THE
ENERGY OF THE INCOMING LOW CONTINUES. OVER KERN COUNTY THE BEST
CHANCES OF SHOWERS AND THUNDERSTORMS WILL BE IN THE EVENING AND
THEN LINGERING SHOWERS AND HIGH ELEVATION SNOW SHOWERS WILL
PERSIST THROUGH THE NIGHT.

FORECAST MODELS THEN MOVE THE LOW TO THE EAST ON THURSDAY HOWEVER
SOME WRAP AROUND FLOW WILL KEEP A THREAT OF SHOWERS IN THE SIERRA
AND KERN COUNTY MOUNTAINS. FOR FRIDAY, A RELATIVELY COOL AND DRY
NORTHERLY FLOW IS PROGGED BEFORE THE NEXT SYSTEM DROPS SOUTHWARD
INTO THE GREAT BASIN AS AN "INSIDE SLIDER" ON SATURDAY. THIS WILL
BRING ADDITIONAL SHOWERS TO THE SIERRA AND POSSIBLY THE EASTERN
PORTIONS OF THE KERN COUNTY DESERT IN WRAP AROUND MOISTURE ON
SUNDAY.

FOR NEXT WEEK, WEAK RIDGING IS PROGGED FOR EARLY IN THE WEEK FOR
DRY WEATHER WITH WITH ANOTHER TROUGH OF LOW PRESSURE AND SOME
PRECIPITATION CHANCES FOR LATE IN THE WEEK.

.SYNOPSIS...
SYSTEM WILL MOVE INTO CENTRAL CALIFORNIA TODAY INCREASING CHANCES
OF SHOWERS AND POSSIBLY A FEW THUNDERSTORMS. BREEZY TO LOCALLY
WINDY CONDITIONS WILL DEVELOP LATER THIS AFTERNOON. SCATTERED
MOUNTAIN SHOWERS AND ISOLATED THUNDERSTORMS ARE EXPECTED TO
CONTINUE INTO THURSDAY MORNING BEFORE DRY WEATHER RETURNS AND
REMAINS THROUGH SUNDAY AFTERNOON. TEMPERATURES WILL AVERAGE A
LITTLE BELOW NORMAL THROUGH THURSDAY THEN CLIMB TO WELL ABOVE
NORMAL OVER THE WEEKEND. SATURDAY AFTERNOON ANOTHER SYSTEM WILL
BEGIN TO MOVE INTO THE REGION AGAIN INCREASING CHANCES FOR
PRECIPITATION.

&&

.DISCUSSION...
BASE OF INCOMING TROUGH WITH COLD FRONT CURRENTLY LOCATED OVER
NORTHERN CALIFORNIA MOVING SOUTHWARD INCREASING MID AND HIGH LEVEL
CLOUDS TO THE AREA. CONVECTION IS ALREADY DEVELOPING JUST OFF OF
THE COAST OF NORTHERN CALIFORNIA DUE TO THE SYNOPTIC LIFTING
ASSOCIATED WITH THE LOW AND COUPLED WITH ISENTROPIC LIFTING AS THE
AIR ASCENDS THE COASTAL RANGE. THIS IS GOOD INDICATION THAT AS THE
LOW MOVES SOUTHWARD THROUGH THE DAY THERE WILL BE PLENTY OF LIFT
AVAILABLE WITH THIS SYSTEM. AS FAR AS INSTABILITY 00Z UPPER AIR
PROFILE FOR KOAK SHOWS COLDER TEMPERATURES ALOFT ALREADY PRESENT
WITH FREEZING LEVEL AT 20 KFT. GUIDANCE SUGGESTS MOST UNSTABLE
CAPE BETWEEN 350-500 J/KG WILL BE AVAILABLE ACROSS CENTRAL
CALIFORNIA TODAY DURING THE LATE MORNING THROUGH THIS EVENING.
MAXIMUM SYNOPTIC LIFTING WILL COINCIDE WITH MAXIMUM DAYTIME
HEATING AND MANY LOCATIONS ACROSS THE SJV WILL HAVE HIGH TEMPS IN
THE MID 80S. AMPLE SURFACE MOISTURE IS ALSO IN PLACE WITH DEW
POINTS ACROSS THE SAN JOAQUIN VALLEY AROUND THE 40 DEGREE MARK.
ALL THE CONVECTIVE INGREDIENTS ARE IN PLACE INCREASING THE CHANCES
FOR THUNDERSTORM ACTIVITY TODAY. WITH ANY OF THE THUNDERSTORMS
THAT MAY DEVELOP...LIGHTNING...SMALL HAIL...AND GUSTY WINDS WILL
BE POSSIBLE. THE STRENGTH OF THE STORMS WILL BE MINIMIZED AS SHEAR
WILL BE VERY LIMITED TODAY. MODEL STEERING FLOW INDICATES STORMS
CELLS THAT DEVELOP WILL MOVE SOUTHEASTWARD. SHOWER AND SCATTERED
THUNDERSTORM ACTIVITY WILL MOVE FROM THE NORTH TO THE SOUTH ACROSS
THE AREA WITH THE BASE OF THE TROUGH. SNOW LEVELS WILL REMAIN HIGH
WITH VALUES ABOVE 7500 FEET.

WINDS WILL BECOME GUSTY AS THE FRONT MOVES THROUGH AND BEHIND THE
FRONT. THE STRONGEST WINDS WILL BE OVER THE KERN COUNTY
MOUNTAINS/DESERT AREAS AND ESPECIALLY THE PASS AREAS. THEREFORE
WE HAVE ISSUED A WIND ADVISORY THROUGH 10 PM PDT TONIGHT. BLOWING
DUST AND SAND WILL BE POSSIBLE AND VISIBILITIES COULD DROP
SUDDENLY.

INCREASED CHANCES OF SHOWERS AND EVEN AN EMBEDDED THUNDERSTORM
WILL REMAIN FOR THE HIGHER ELEVATIONS OF THE COASTAL RANGE...KERN
COUNTY MOUNTAINS...AND THE SOUTHERN SIERRA THROUGH THURSDAY
MORNING. RIDGING WILL BEGIN TO INCH EASTWARD INTO THE REGION
BEGINNING LATE THURSDAY. THERE IS SOME UNCERTAINTY AS TO THE
STRENGTH AND TIMING OF ANOTHER SYSTEM THAT GUIDANCE INDICATES
WILL MOVE INTO THE REGION BEGINNING SATURDAY AFTERNOON ALONG THE
EASTERN SIDE OF PACIFIC RIDGING. UNSETTLED CONDITIONS WILL REMAIN
THROUGH MONDAY AND PERHAPS INTO TUESDAY MORNING. CLEARING AND
DRIER CONDITIONS WILL TEMPORARILY RETURN ON TUESDAY AS THE RIDGE
AXIS MOVES OVER THE WEST COAST. ANOTHER PACIFIC SYSTEM LOOKS TO
MOVE INTO THE REGION LATE THURSDAY AGAIN INCREASING PRECIPITATION
CHANCES TO THE AREA.

DRY AND MILD CONDITIONS WILL PREVAIL TODAY...THEN ANOTHER PACIFIC
STORM SYSTEM IS EXPECTED TO MOVE IN ON WEDNESDAY BRINGING SHOWERS
AND POSSIBLY THUNDERSTORMS TO CENTRAL CALIFORNIA. BREEZY TO LOCALLY
WINDY CONDITIONS WILL DEVELOP WEDNESDAY AFTERNOON. SCATTERED
MOUNTAIN SHOWERS AND STORMS ARE EXPECTED TO CONTINUE ON THURSDAY
BEFORE DRY WEATHER RETURNS INTO THE WEEKEND. TEMPERATURES WILL
AVERAGE A LITTLE BELOW NORMAL THROUGH THURSDAY THEN CLIMB TO WELL
ABOVE NORMAL OVER THE WEEKEND.

&&

.DISCUSSION...
A WEAK RIDGE OF HIGH PRESSURE IS OVER CENTRAL CALIFORNIA TODAY
WITH SOME HIGH CLOUDS MOVING ACROSS THE AREA. THE RIDGE WILL SHIFT
EASTWARD TONIGHT AS THE NEXT LOW PRESSURE SYSTEM MOVES INTO THE
REGION WEDNESDAY. A FEW SHOWERS ARE POSSIBLE OVER THE SIERRA
AND COASTAL RANGE BY EARLY WEDNESDAY MORNING BUT THE BEST CHANCES
WILL BE DURING THE AFTERNOON AND EVENING.

MODELS CONTINUE TO INDICATE SUFFICIENT INSTABILITY TO WARRANT A
SLIGHT CHANCE OF THUNDERSTORMS FROM AROUND NOON WEDNESDAY THROUGH
THE EVENING. THE BEST CHANCE LOOKS TO BE OVER THE WEST CENTRAL
SAN JOAQUIN VALLEY EARLY IN THE AFTERNOON...BUT THUNDERSTORMS MAY
PROPAGATE WELL SOUTHEAST INTO THE SOUTH VALLEY AND ALSO DEVELOP
OVER MOUNTAINS. SNOW LEVELS WILL GENERALLY BE ABOVE 7000 FEET FOR
THE BULK OF PRECIPITATION BUT CAN BE LOWER AT TIMES IN HEAVIER
SHOWERS. HIGHLY VARIABLE PRECIPITATION AMOUNTS ARE EXPECTED DUE TO
THE CONVECTIVE NATURE BUT WE COULD SEE 2 TO 5 INCHES OF SNOW IN
SOME LOCATIONS ABOVE 7500 FEET.

THE SYSTEM BECOMES A LARGE CLOSED UPPER LOW CENTERED AROUND LAS
VEGAS EARLY THURSDAY WITH WRAPAROUND MOISTURE PROVIDING MORE
CHANCES FOR SHOWERS OVER THE MOUNTAINS. CAN NOT RULE OUT AN
ISOLATED THUNDERSTORM OR TWO OVER THE SIERRA THURSDAY
AFTERNOON. THE SYSTEM OPENS UP AND EXITS TO THE FOUR CORNERS
REGION ON FRIDAY WITH PERHAPS A FEW LINGERING SHOWERS IN THE SO
SIERRA DURING THE AFTERNOON BEFORE IT PUSHES EAST INTO THE
ROCKIES.

A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE EASTERN PACIFIC
FRIDAY AND SATURDAY...PUSHING NORTH INTO THE PACIFIC NORTHWEST BY
SUNDAY. AT THE SAME TIME...ANOTHER SHORTWAVE TROUGH RIDES OVER THE
TOP OF THE RIDGE AND DROPS SOUTH THROUGH NEVADA SATURDAY AND
INTO ARIZONA BY SUNDAY. THIS FEATURE MAY BE FAR ENOUGH WEST TO
BRING A SLIGHT CHANCE OF SHOWERS TO THE SIERRA NEVADA SATURDAY
AFTERNOON AND EVENING BEFORE IT MOVES EAST ON SUNDAY. THIS
FEATURE WILL DELAY THE RIDGE FROM MOVING INLAND...HOLDING IT
ALONG THE COAST SATURDAY AND MOVING IT INLAND SUNDAY AND MONDAY.
TEMPERATURES WILL STILL WARM SEVERAL DEGREES ON FRIDAY AND
SATURDAY...WITH CONTINUED WARMING SUNDAY THROUGH TUESDAY.
TEMPERATURES IN THE SAN JOAQUIN VALLEY WILL BE IN THE LOWER 90S
MONDAY AND TUESDAY...ABOUT 10 DEGREES ABOVE NORMAL.
