The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Hanford, CA wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 24, 5:10 PM PDT, 2 hours 33 minutes earlier.
Area forecast discussion, Apr 24, 5:10 PM PDT, 2 hours 33 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA 510 PM PDT SUN APR 24 2016 ...UPDATED FOR SHOWERS IN THE SAN JOAQUIN VALLEY THIS EVENING... .SYNOPSIS... SOME SHOWERS ARE EXPECTED OVER THE MOUNTAINS TONIGHT THROUGH MONDAY. OTHERWISE...EXPECT GUSTY WINDS THROUGH THE FAVORED PASSES AND CANYONS...WITH THE STRONGEST GUSTS ON MONDAY. A STORM SYSTEM COULD BRING WET WEATHER TO MUCH OF THE CENTRAL CALIFORNIA INTERIOR BY WEDNESDAY. TEMPERATURES WILL REMAIN COOLER THAN AVERAGE THROUGH THE END OF THE WEEK. && .UPDATE... UPDATE FORECAST TO INCLUDE A SLIGHT CHANCE OF SHOWERS ACROSS THE VALLEY FLOOR. CONVECTIVE SHOWERS FROM THE COASTAL RANGE ABLE TO MOVE EAST AND INTO THE SAN JOAQUIN VALLEY. CURRENTLY...SHOWERS WITH MEASURABLE PRECIPITATION HAVE MOVED THROUGH GUSTINE AND COALINGA WITH MORE SHOWERS DEVELOPING ACROSS THE EAST SIDE OF THE VALLEY. DAYLIGHT WILL CONTINUE FOR A FEW MORE HOURS KEEPING THE INSTABILITY FOR ADDITIONAL SHOWERS. DUE TO THE NATURE OF TODAY/S SHOWERS BEING DRIVEN BY AFTERNOON HEATING...WILL EXPECT CONVECTIVE SHOWERS TO DIMINISH AFTER SUNSET. WIND SPEEDS WILL CONTINUE TO INCREASE THROUGH THIS EVENING AS WIND ADVISORY ARE NOW IN PLACE FOR THE FAVORED AREAS OF THE SAN JOAQUIN VALLEY AND KERN COUNTY MOUNTAINS AND DESERTS. && .PREV DISCUSSION... /ISSUED 326 PM PDT SUN APR 24 2016/ SOME SCATTERED AFTERNOON CUMULUS HAVE DEVELOPED ACROSS THE SAN JOAQUIN VALLEY AS THE MORNING MID AND HIGH CLOUDS HAVE PUSHED TO THE SOUTH AND EAST. FOR THE REST OF TODAY...A FEW SCATTERED SHOWERS HAVE ALREADY DEVELOPED OVER THE HIGH SIERRA NEAR YOSEMITE NATIONAL PARK. WITH SOME MARGINAL INSTABILITY...CAN'T RULE OUT THE CHANCE OF A FEW THUNDERSTORMS DEVELOPING IN THE SIERRA FROM YOSEMITE TO SEQUOIA NATIONAL PARKS. FOR THE SHORT-TERM...OUR MAIN CONCERN IS THE POTENTIAL FOR GUSTY WINDS IN PORTIONS OF THE SAN JOAQUIN VALLEY...AND HIGH WINDS IN THE KERN COUNTY MOUNTAINS AND DESERT. A WIND ADVISORY FOR THE WESTERN SAN JOAQUIN VALLEY BEGINNING NOON PDT MONDAY THROUGH 8 PM PDT MONDAY...AND FOR THE KERN COUNTY MOUNTAINS AND DESERT BEGINNING 5 PM PDT SUNDAY THROUGH NOON PDT MONDAY IS IN EFFECT. IN ADDITION A HIGH WIND WATCH IS IN EFFECT FOR THE KERN COUNTY MOUNTAINS AND DESERT BEGINNING NOON PDT MONDAY THOUGH 11 PM PDT MONDAY. THE STORM SYSTEM THAT WILL BE RESPONSIBLE FOR BRINGING GUSTY WINDS TO THE REGION IS CURRENTLY OFF THE COAST OF OREGON AND WILL MOVE INLAND OVERNIGHT. THE SYSTEM'S TRAJECTORY INTO THE GREAT BASIN WILL BRING: 1) INCREASED SURFACE PRESSURE GRADIENTS...2) A NW TO SE-ORIENTED 300 MB JET OVER THE COUNTY WARNING AREA...AND 3) A COUPLED ATMOSPHERIC COLUMN. THIS SYNOPTIC SETUP IS THE PRIMARY REASON FOR THE CURRENT WIND PRODUCTS. BLOWING DUST WILL ALSO BE AN ISSUE WITH THESE GUSTY WINDS. UNFORTUNATELY IT APPEARS THE WINDS ARE EXPECTED TO BE THE MAIN IMPACT WITH THIS SYSTEM...SOME RAIN AND SNOW SHOWERS EXPECTED IN THE SIERRA AND ADJACENT FOOTHILLS. AS THE INSIDE SLIDER SYSTEM PUSHES INTO THE NORTH AMERICAN CONTINENT ON TUESDAY...SHORT-WAVE RIDGING WILL BRING A QUIET WEATHER DAY TO CENTRAL CALIFORNIA. BY WEDNESDAY AND THURSDAY...A POTENTIALLY WETTER STORM SYSTEM WILL TAKE AIM ON THE REGION. AS MODELS ARE SUGGESTING SOME MARGINAL INSTABILITY OVER THE SIERRA AND FOOTHILLS...WE'VE INTRODUCED THE SLIGHT CHANCE OF THUNDER FOR THURSDAY AFTERNOON. GFS AND ECWMF HAVE THE SYSTEM SLOWLY MOVING OUT OF THE GREAT BASIN BY FRIDAY. BEYOND FRIDAY...A RIDGE WILL REBUILD ACROSS THE WEST COAST AND WILL HELP TO BOOST TEMPERATURES ABOVE NORMAL BY THE WEEKEND AND INTO EARLY NEXT WEEK. && AVIATION... AREAS OF MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURING IFR CONDITIONS WITH SHOWERS POSSIBLE OVER THE SOUTHERN SIERRA NEVADA AFTER 18Z TODAY. ISOLATED THUNDERSTORMS POSSIBLE OVER THE SOUTHERN SIERRA NEVADA BETWEEN 20Z TODAY AND 06Z MONDAY. AREAS OF MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURING IFR CONDITIONS WITH SHOWERS POSSIBLE OVER THE TEHACHAPI MOUNTAINS AFTER 06Z MONDAY. OTHERWISE...VFR CONDITIONS WILL PREVAIL ACROSS THE CENTRAL CALIFORNIA INTERIOR DURING THE NEXT 24 HOURS. && .AIR QUALITY ISSUES... NONE. && .CERTAINTY... THE LEVEL OF CERTAINTY FOR DAYS 1 AND 2 IS HIGH. THE LEVEL OF CERTAINTY FOR DAYS 3 THROUGH 7 IS MEDIUM. CERTAINTY LEVELS INCLUDE LOW...MEDIUM...AND HIGH. PLEASE VISIT WWW.WEATHER.GOV/HNX/CERTAINTY.PHP FOR ADDITIONAL INFORMATION AN/OR TO PROVIDE FEEDBACK. && .HNX WATCHES/WARNINGS/ADVISORIES... WIND ADVISORY UNTIL NOON PDT MONDAY CAZ095-098-099.
