The radar

The Reno radar (KRGX), 101 km from the middle of the area, began a volume at 02:50 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, 2.8 hours before the alert went out and 153 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.

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 Reno, NV wrote its last area forecast discussion before this flash flood warning went out at Jul 9, 1:21 PM PDT, 6 hours 26 minutes earlier.

Area forecast discussion, Jul 9, 1:21 PM PDT, 6 hours 26 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
121 PM PDT FRI JUL 9 2010

.SHORT TERM...

UPPER LEVEL SHORTWAVE CONTINUES TO HANG OFF THE CA COAST...INSTEAD
OF MOVING INLAND AS PREVIOUSLY PROGGED. THIS WILL LIMIT
THUNDERSTORM COVERAGE ACROSS THE CWA TODAY COMPARED TO WHAT WAS
THOUGHT THE PREVIOUSLY TWO DAYS. THE DIVERGENCE ZONE AHEAD OF THE
WAVE IS GENERATING THUNDERSTORMS ALREADY THROUGH EXTREME EASTERN
CHURCHILL AND PERSHING COUNTIES EASTWARD INTO NORTHEASTERN NEVADA.
ELSEWHERE ACROSS THE EASTERN SIERRA AND WESTERN NEVADA...
THUNDERSTORMS ARE STILL EXPECTED TO DEVELOP LATER THIS AFTERNOON
AND EVENING...WITH THE BEST DEVELOPMENT INITIALLY THROUGH
LASSEN...NORTHERN WASHOE...AND NORTHERN PERSHING COUNTIES. AS THE
ZEPHYR WINDS KICK IN LATE THIS AFTERNOON...STORMS HAVE THE
POTENTIAL TO BECOME STRONGER ALONG THE LEADING CONVERGENT EDGE.

LINGERING MOISTURE AND INSTABILITY WILL KEEP THUNDERSTORMS IN THE
FORECAST ONCE AGAIN ON SATURDAY AFTERNOON. THE BEST FOCUS WILL BE
THROUGH MONO AND MINERAL COUNTIES WHERE THE BEST MOISTURE AND JET
DYNAMICS WILL COMBINE WITH A NATURAL CONVERGENCE ZONE. HAVE KEPT
SCATTERED THUNDERSTORMS THROUGH THIS AREA AND ISOLATED THUNDER
ELSEWHERE IN THE FORECAST.

HIGH PRESSURE TRIES TO BUILD INTO THE FORECAST AREA FROM THE WEST
SUNDAY INTO MONDAY...THOUGH IS HELD AT BAY BY A WAVE PASSING
THROUGH IDAHO AND MONTANA. THIS WILL LIMIT THE WARMING POTENTIAL
SLIGHTLY...HOWEVER TEMPERATURES WILL REMAIN A FEW DEGREES ABOVE
NORMAL. THIS WILL BE A DRIER AND MORE STABLE AIR MASS...BUT IT
WILL TAKE A FEW DAYS TO MODERATE THE MOIST AND UNSTABLE AIR MASS
THAT IS CURRENTLY IN PLACE. HAVE LEFT A SLIGHT CHANCE OF
THUNDERSTORMS THROUGH THE MONO-MINERAL CONVERGENCE ZONE SUNDAY
AFTERNOON...BUT REMOVED ALL MENTIONABLE POPS BY MONDAY. DF

.LONG TERM...TUESDAY THROUGH FRIDAY...

THE ECMWF HAS CONTINUED TO TREND WITH THE GFS IN SETTING UP THE MAIN
AREA OF HIGH PRESSURE OVER THE AZ/MEXICO BORDER. THIS WILL ALLOW
WARM AND BREEZY CONDITIONS ACROSS THE GREAT BASIN NEXT WEEK IN
ASSOCIATION WITH TWO PASSING SHORTWAVES TO OUR NORTH TUESDAY AND
FRIDAY. TEMPERATURES WILL REMAIN SEVERAL DEGREES ABOVE NORMAL
THROUGH THE LONG TERM PERIOD WITH DRY AIR AND POOR OVERNIGHT RH
RECOVERIES.

BY WEDNESDAY AFTERNOON DIFFERENCES IN THE MODELS ARISE AS THE ECMWF
FLATTENS OUT TO A BARELY AMPLIFIED SHORTWAVE RIDGE BEHIND THE FIRST
SHORTWAVE WHILE THE GFS CONTINUES TO DIG HEIGHTS IN A WEAK
TROUGH-LIKE PATTERN. THE GFS SUPPORTS BREEZIER AFTERNOONS WHILE THE
ECMWF SHOWS WARMER TEMPERATURES AND LIGHTER WINDS. HAVE KEPT
AFTERNOON MAX TEMPS IN THE UPPER 90S FOR WESTERN NV AND MID TO UPPER
80S IN THE SIERRA THROUGH THE WEEK AS BOTH SOLUTIONS KEEP H700 TEMPS
BETWEEN 13C AND 17C.

THE SECOND SHORTWAVE LOOKS TO PASS OVER WA/ID/MT FRIDAY PROVIDING A
WEAK INFLUENCE OVER OUR AREA WITH SLIGHTLY COOLER TEMPS AND
INCREASING AFTERNOON WEST WINDS. WITH MODERATE CONFIDENCE IN THE GFS
AND ITS ENSEMBLES AND LACK OF CONSISTENCY IN THE ECMWF...DID NOT
MAKE MANY CHANGES TO THE END OF THE PERIOD. LABELLE

&&

.AVIATION...

TOWERING CU DEVELOPMENT ALONG THE SIERRA AND INTO WESTERN NV THROUGH
03Z WITH POTENTIAL FOR ISOLATED THUNDERSTORMS AT ALL TERMINALS.
OUTFLOW WINDS ARE MAIN THREAT WITH GUSTS UP TO 45KTS POSSIBLE. BRIEF
PERIODS OF MVFR VIS IN THUNDERSTORMS AND SHOWERS ALSO POSSIBLE.
LIGHT WEST WINDS AND VFR CONDITIONS INTO SATURDAY. LABELLE
