The radar

The Sacramento radar (KDAX), 172 km from the middle of the area, began a volume at 21:20 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Oakland, CA (KOAK), launched 12:00Z, 9.3 hours before the alert went out and 204 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

CENTRAL MARIPOSA AND CENTRAL TUOLUMNE COUNTIES...

AT 224 PM PDT...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO
INDICATE A THUNDERSTORM PRODUCING VERY HEAVY RAIN OVER THE WARNED
AREA. AN AUTOMATED GAGE AT WHITE WOLF REPORTED 0.45 INCH OF RAIN IN 
ONE HOUR. THE THUNDERSTORM WAS MOVING INTO THE EASTERN EDGE OF THE 
RIM FIRE BURN SCAR.

RIDGE AND HETCH HETCHY.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

IN HILLY TERRAIN THERE ARE HUNDREDS OF LOW WATER CROSSINGS WHICH ARE
POTENTIALLY DANGEROUS IN HEAVY RAIN. DO NOT ATTEMPT TO TRAVEL ACROSS
FLOODED ROADS. FIND ALTERNATE ROUTES. IT TAKES ONLY A FEW INCHES OF
SWIFTLY FLOWING WATER TO CARRY VEHICLES AWAY.

What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at Jul 15, 3:18 AM PDT, 11 hours 1 minute earlier.

Area forecast discussion, Jul 15, 3:18 AM PDT, 11 hours 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
318 AM PDT TUE JUL 15 2014

.SYNOPSIS...
TEMPERATURES WILL CONTINUE TO RUN ABOVE SEASONAL NORMALS FOR THE
NEXT SEVERAL DAYS AS HIGH PRESSURE REMAINS OVER THE DESERT
SOUTHWEST. TROPICAL MOISTURE WILL CONTINUE TO STREAM NORTHWEST OVER
THE AREA ALLOWING FOR INCREASED CLOUD COVER AND AT LEAST A SLIGHT
CHANCE OF SHOWERS AND THUNDERSTORMS ALONG THE SIERRA CREST AS WELL
AS THE KERN COUNTY MOUNTAINS AND DESERT. CHANCES FOR SHOWERS AND
THUNDERSTORMS WILL THEN MIGRATE NORTH AND BE CONFINED TO THE HIGHER
ELEVATIONS OF THE SOUTHERN SIERRA WEDNESDAY THROUGH SATURDAY.

&&

.DISCUSSION...ABUNDANT MID LEVEL MOISTURE AND WEAK MID LEVEL
INSTABILITY ALLOWED LIGHT TO MODERATE RAIN SHOWERS TO FORM OVER
MAINLY KERN...TULARE...AND KINGS COUNTIES OVERNIGHT. THE 00Z RUN OF
THE NAM DID INDICATE THAT SEVERAL VORT MAXES WOULD MOVE QUICKLY
NORTHWEST FROM THE SOUTHERN SIERRA CREST INTO THE VALLEY DURING
THE TIME FRAME THAT SHOWERS FORMED. THE HRRR WAS A LITTLE SLOW TO
CAPTURE THE CURRENT SCENARIO...BUT IT DOES INDICATE THAT THE
SHOWERS WILL CONTINUE TO MOVE WEST OUT OF THE AREA...LEAVING
BEHIND DRY CONDITIONS AFTER 12Z. MODERATE CONFIDENCE.

OTHERWISE...WITH SIGNIFICANT MID AND UPPER LEVEL
CLOUDINESS...TEMPERATURES SO FAR ONLY FELL INTO THE UPPER 70S TO
MID 80S THROUGH MANY OF THE VALLEY AND DESERT LOCATIONS. IN
FACT...BAKERSFIELD SET AN ALL NEW RECORD HIGH MINIMUM TEMPERATURE
FOR YESTERDAY...ONLY FALLING TO 83 DEGREES...WHICH BROKE THE OLD
RECORD OF 81 DEGREES SET IN 1972. WE WILL CONTINUE TO MONITOR
THESE HIGH MINIMUM TEMPERATURES THE NEXT FEW NIGHTS...WITH RECORDS
POSSIBLE.

MAIN CONCERN FOR TODAY WILL BE THE POSSIBILITY OF THUNDERSTORMS
ONCE AGAIN OVER THE SIERRA CREST AS WELL AS THE KERN COUNTY
MOUNTAINS AND DESERT. HIGH CONFIDENCE THAT AT LEAST SOME PART OF
THE SOUTHERN SIERRA CREST WILL SEE CONVECTIVE ACTION...WITH MUCH
LESS CONFIDENCE OVER KERN COUNTY. MOST OF THE SHORT TERM MODELS
KEEP ALL CONVECTION NORTH OF KERN COUNTY...HOWEVER...WITH THE
UNCERTAINTY...LEFT IN THE SLIGHT CHANCE. WITH REGARDS TO THE
SIERRA CREST...MU CAPE VALUES INCREASE TO NEARLY 800
J/KG THIS AFTERNOON...SIGNIFICANTLY MORE UNSTABLE THIS AFTERNOON
COMPARED TO MONDAY AFTERNOON. THIS SHOULD RESULT IN QUITE A FEW
MORE THUNDERSTORMS COMPARED TO YESTERDAY. THE HRRR DEVELOPS
THUNDERSTORMS OVER THE CREST AS EARLY AS 19Z...WITH STORMS MOVING
WEST. IT IS POSSIBLE THAT THESE STORMS WILL MOVE INTO THE
FOOTHILLS...SO THIS WILL NEED TO BE WATCHED CLOSELY AND POSSIBLY
ADDED TO THE FORECAST THIS AFTERNOON.

OTHERWISE...MAIN PLUME OF MOISTURE IS FORECAST TO SLOWLY SHIFT
NORTH WEDNESDAY INTO THE WEEKEND...SHIFTING THUNDERSTORM CHANCES
NORTH AS WELL. ON WEDNESDAY...THUNDERSTORMS ARE FORECAST TO REMAIN
OVER THE CREST AND BY FRIDAY...MAINLY FROM FRESNO COUNTY NORTHWARD
ALONG THE CREST.

TEMPERATURES WILL BE ON THE DOWNWARD TREND WEDNESDAY INTO THE END
OF THE WORK WEEK...WITH THURSDAY AND FRIDAY THE COOLEST DAYS OF
THE WEEK. TEMPERATURES ON THESE DAYS WILL RANGE FROM THE LOW TO
MID 90S THROUGH MANY OF THE VALLEY LOCATIONS...NEAR NORMAL FOR THE
MIDDLE OF JULY.

&&

.AVIATION...
SCATTERED THUNDERSTORMS WITH LOCAL MVFR CEILINGS CAN BE EXPECTED
IN THE SOUTHERN SIERRA NEVADA BETWEEN 19Z TODAY AND 04Z WEDNESDAY.
ISOLATED THUNDERSTORMS ARE POSSIBLE IN THE KERN COUNTY MOUNTAINS
AND DESERT THIS AFTERNOON INTO EARLY THIS EVENING. OTHERWISE...
VFR CONDITIONS WILL PREVAIL THROUGHOUT THE CENTRAL CALIFORNIA
INTERIOR DURING THE NEXT 24 HOURS.

&&

.AIR QUALITY ISSUES...
ON TUESDAY JULY 15 2014... UNHEALTHY FOR SENSITIVE GROUPS IN
SEQUOIA NATIONAL PARK AND FOREST.
