The radar
The Reno radar (KRGX), 142 km from the middle of the area, began a volume at 00:32 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
Reno, NV (KREV), launched 00:00Z, 0.5 hours before the alert went out and 158 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
524 PM PDT FRI JUL 16 2010
.UPDATE...
STORMS QUICKLY PUSHING EAST ACROSS AREAS NORTH OF US-50...THUS
HAVE REMOVED NORTHERN LYON FROM THE FLASH FLOOD WATCH.
STORMS CONTINUE TO TRAIN OVER MONO COUNTY...WHERE THE HIGHEST
POTENTIAL FOR FLASH FLOODS WILL CONTINUE THROUGH THIS EVENING.
OVER THE SWEETWATER MOUNTAINS IN NORTHERN MONO COUNTY RADAR
RAINFALL ESTIMATES HAVE EXCEEDED 2.50 INCHES SINCE 3 PM.
ADDITIONAL RAINFALL OVER THE HIGH SIERRA IN MONO COUNTY HAVE
CAUSED MINOR ROCK SLIDES ON TIOGA PASS...CA 120. BRONG
&&
.PREVIOUS DISCUSSION... /ISSUED 408 PM PDT FRI JUL 16 2010/
UPDATE...DID CLEAR RENO-TAHOE ZONES FROM FLASH FLOOD WATCH AS
STORMS MOVING WELL EAST OF THE AREA...WITH SOUTHWEST-WEST WINDS
INCREASING OVER THE SIERRA CREST.
MAIN CONCERN FOR FLASH FLOODING CONTINUES TO BE MONO COUNTY AS
STORMS SHOWING LITTLE TO NO MOTION AND/OR STORM TRAINING. BRONG
PREVIOUS DISCUSSION... /ISSUED 230 PM PDT FRI JUL 16 2010/
SHORT TERM... THUNDERSTORMS ARE THE MAIN WEATHER CONCERN AT THIS
TIME WITH THE POTENTIAL FOR FLASH FLOODING THIS AFTERNOON/EVENING.
HIGH PRESSURE OVER THE FOUR CORNERS WILL BRING ANOTHER HOT DAY
TODAY WITH MOIST SOUTHERLY FLOW IN THE MID LEVELS. PWATS HAVE
INCREASED SIGNIFICANTLY SINCE YESTERDAY WITH THE 12Z RNO SOUNDING
SHOWING 0.93 INCH. THE COMBINATION OF HOT WEATHER AND INCREASING
MOISTURE WILL RESULT IN ISOLATED TO SCATTERED THUNDERSTORMS THIS
AFTERNOON AND EVENING. WEAK STEERING LEVEL WINDS WILL CONTRIBUTE
TO SLOW STORM MOTIONS...AND WITH THE AMOUNT OF MOISTURE IN
PLACE...FLASH FLOODING IS THE BIGGEST CONCERN. THE GREATEST RISK
FOR THUNDERSTORMS AND FLASH FLOODING WILL GENERALLY BE SOUTH OF
I-80 AND WEST OF HWY 95...ALTHOUGH ISOLATED THUNDERSTORMS WITH
HEAVY RAIN ARE ALSO POSSIBLE TO THE NORTH AND EAST OF THESE AREAS
AS WELL.
MAX TEMPERATURES WILL LIKELY BE MODERATED SOME DUE TO THE INCREASE
IN MOISTURE AND CLOUDS...ESPECIALLY THOSE AFOREMENTIONED AREAS SOUTH
OF I-80 AND WEST OF HWY 95. ELSEWHERE...HIGH TEMPS WILL REMAIN WELL
ABOVE SEASONAL AVERAGES WITH UPPER 90S TO 100S IN THE LOWER
VALLEYS/SINKS AND MID TO UPPER 80S IN THE TAHOE BASIN.
REMOVED THE SLIGHT CHANCE OF NOCTURNAL STORMS FROM THE FORECAST FOR
TONIGHT AS THE BEST FORCING PER THE DYNAMIC TROPOPAUSE APPEARS TO
MOVE THROUGH DURING THE EVENING HOURS. FURTHERMORE...OPERATIONAL
MODELS HAVE REALLY BACKED OFF ON THE AMOUNT OF ELEVATED INSTABILITY
OVERNIGHT WITH MUCAPE 0-50 J/KG...HLTT IN THE 20S TO NEAR 30...AND
500-300 MB LAPSE RATES OF 6.75C OR LESS.
FOR SATURDAY THROUGH MONDAY...A SHORTWAVE TROUGH APPROACHING THE PAC
NW WILL ACT TO FLATTEN THE RIDGE OVER THE AREA AND EVENTUALLY BRING
DRIER WESTERLY FLOW TO THE REGION. LINGERING MOISTURE COULD STILL
CAUSE AN ISOLATED STORM OR TWO TO DEVELOP OVER MINERAL AND MONO
COUNTIES AND ALSO ALONG THE LASSEN CONVERGENCE ZONE SATURDAY. DRY
SUNDAY AND MONDAY. HIGH TEMPERATURES WILL CHANGE VERY LITTLE ON
SATURDAY. A LITTLE COOLER SUNDAY...THEN AN ADDITIONAL SEVERAL
DEGREES OF COOLING MONDAY AS A TROUGH SETTLES OVER THE AREA. HIGHS
BY MONDAY COULD FALL TO NEAR SEASONAL AVERAGES. MODELS CONTINUE TO
SHOW AN INCREASED THERMAL GRADIENT SETTING UP SUNDAY/MONDAY AS THE
TROUGH MOVES IN. THIS WILL CAUSE DRY GUSTY AFTERNOON WINDS WITH LOW
HUMIDITY VALUES AND POOR OVERNIGHT RECOVERIES. SCV
LONG TERM...TUESDAY THROUGH FRIDAY... MADE VERY MINIMAL CHANGES
TO THE LONG TERM. MODELS STILL BRING UPPER TROUGH INTO THE PAC NW
WITH SOUTHWEST FLOW INCREASING ALOFT. AN EXTREMELY DRY AIR MASS IN
PLACE WILL ALLOW FOR VERY POOR RELATIVE HUMIDITY RECOVERIES
OVERNIGHT OVER MUCH OF THE REGION. WIDESPREAD AREAS OF SINGLE
DIGITS AND TEENS FOR RELATIVE HUMIDITY WILL PERSIST DURING THE
TUESDAY THROUGH FRIDAY TIME PERIOD. TEMPERATURES ARE EXPECTED TO
BE NEAR NORMAL AS A COOLING TREND WITH THE FALLING HEIGHTS
ASSOCIATED WITH THE TROUGH.
UPPER LEVEL JET WILL MOVE INTO THE NORTHERN PORTIONS OF THE CWA
WHICH WILL BRING UPPER LEVEL SUPPORT FOR WINDS NEAR THE SURFACE AND
THE RIDGETOPS. A STRONG THERMAL GRADIENT WILL SETUP BETWEEN THE
SIERRA AND WESTERN NV...WHICH WILL FURTHER ALLOW FOR AN INCREASE IN
THE WINDS...ESPECIALLY IN THE AFTERNOONS. WITH THE EXTREMELY DRY AIR
MASS AND BREEZY WINDS IN PLACE...IT IS POSSIBLE THAT CRITICAL FIRE
WEATHER CONDITIONS WILL CONTINUE FROM AT LEAST MONDAY INTO TUESDAY
OF NEXT WEEK...ESPECIALLY FOR THE LOWER ELEVATIONS.
TROUGH WILL REMAIN OVER THE PAC NW THROUGH THU...WITH A RIDGE
POSSIBLE BUILDING IN ON FRIDAY. MODEL DIFFERENCES DO NOT PROMOTE
HIGH CONFIDENCE IN THE EXIT OF THE TROUGH AT THIS TIME SO DID NOT GO
WITH A PARTICULAR SOLUTION YET. LINDAMAN
AVIATION...
INCREASED MOISTURE INTO THE REGION WILL CONTINUE TO BRING ISOLATED
THUNDERSTORMS THIS AFTERNOON AND EARLY EVENING. STORMS HAVE FORMED
NEAR SOUTH LAKE TAHOE AND THE PINE NUT MOUNTAINS...BRINGING HEAVY
RAIN AND LOWER CEILINGS. WEST WINDS IN THE AFTERNOON WILL END THE
THUNDERSTORMS IN THE TAHOE BASIN BY 23Z...THEN PUSHING EAST OF KRNO
BY 02Z.
THUNDERSTORMS MAY CAUSE STRONG GUSTY AND ERRATIC OUTFLOW WINDS UP
TO 40KT...ESPECIALLY IN THE LATE AFTERNOON OVER KRNO. LINDAMAN
FIRE WEATHER... A SHORTWAVE MOVING ACROSS THE PACIFIC NORTHWEST
WILL FLATTEN THE RIDGE CURRENTLY OVER THE FORECAST AREA ON
SATURDAY...CUTTING OFF THE MOISTURE SOURCE THAT LED TO TODAYS
OUTBREAK OF THUNDERSTORMS. THE BEST CHANCE FOR STORMS ON SATURDAY
WILL BE ACROSS MONO AND MINERAL COUNTIES WHERE THE MOISTURE WILL
LINGER THE LONGEST.
AS THE RIDGE SLIDES TO THE EAST ON SUNDAY...A PLUME OF VERY DRY
AIR ALOFT WILL MOVE ACROSS NORTHERN CALIFORNIA AND
NEVADA. THIS WILL SET THE STAGE FOR CRITICAL FIRE WEATHER
CONDITIONS ACROSS THE AREA ON SUNDAY AND MONDAY. A FIRE WEATHER
WATCH HAS BEEN ISSUED FOR SUNDAY AFTERNOON THROUGH MONDAY EVENING
FOR AREAS ALONG AND EAST OF HIGHWAY 395.
THE GREATEST CONCERN ON SUNDAY ARE GUSTY WINDS...WITH WESTERLY
WIND ANOMALIES FROM THE GEFS AT 700 MB 2-3 STANDARD DEVIATIONS
ABOVE NORMAL ON SUNDAY AFTERNOON. THESE WINDS WHEN MIXED TO THE
SURFACE COMBINED WITH LOW RH'S COULD CREATE CRITICAL FIRE
CONDITIONS AT MID-SLOPE AND VALLEY LOCATIONS ON SUNDAY AFTERNOON
AND EVENING.
AFTER A NIGHT OF POOR RH RECOVERIES...MONDAY LOOKS TO BE THE BEST CHANCE
FOR CRITICAL FIRE WEATHER CONDITIONS. THE DRY AIR INTRUSION ALOFT
WILL HAVE HAD PLENTY OF TIME TO MIX TO THE SURFACE BY MONDAY...AND
WHEN COMBINED WITH AFTERNOON ZEPHYR WINDS...EXPECT CRITICAL
CONDITIONS TO DEVELOP ON MONDAY AFTERNOON. SREF PROBABILITY OF RH
LESS THAN 15 PERCENT IS GREATER THAN 90 PERCENT ACROSS MUCH OF THE
FIRE WEATHER DISTRICT ON MONDAY. MYRICK
