The radar

The Reno radar (KRGX), 170 km from the middle of the area, began a volume at 22:01 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 12:00Z, 10.0 hours before the alert went out and 91 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.

SAFELY. MOVE TO HIGHER GROUND.

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.

Area forecast discussion, Jul 15, 2:00 PM PDT, 59 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
200 PM PDT TUE JUL 15 2014

.SYNOPSIS...MONSOON MOISTURE WILL KEEP SHOWERS AND THUNDERSTORMS
GOING ACROSS CENTRAL NEVADA INTO TONIGHT. THUNDERSTORMS WILL BE
CONFINED TO MAINLY NYE COUNTY ON WEDNESDAY...BEFORE RETURNING
NORTHWARD TO MUCH OF NEVADA ON THURSDAY. MONSOON MOISTURE WILL
KEEP THUNDERSTORMS IN THE FORECAST ACROSS NORTHERN NEVADA FRIDAY
AND SATURDAY.

&&

.SHORT TERM...TONIGHT THROUGH THURSDAY.

DRIER MORE STABLE AIR HAS ARRIVED IN NORTHERN NEVADA THIS
AFTERNOON, WITH CUMULUS ABSENT NORTH OF I-80 AND ONLY SOME PASSING
CIRRUS. STILL HOT, BUT DECREASED THICKNESSES WILL ALLOW MAX TEMPS
TO REMAIN IN THE UPPER 90S FOR MOST VALLEYS. BETTER THAN THE
104-107 WE SAW YESTERDAY.

A DIFFERENT STORY SOUTH OF I-80 THROUGH THIS EVENING. MONSOON
MOISTURE REMAINS PLENTIFUL ACROSS NYE, WHITE PINE, AS WELL AS
SOUTHERN LANDER AND EUREKA COUNTIES. NUMEROUS SLOW-MOVING
THUNDERSTORMS HAVE ALREADY DEVELOPED, AND EXPECT COVERAGE TO
INCREASE THROUGH EARLY EVENING AS NAM/HRRR SUGGESTS. DID AN EARLIER
UPDATE TO INCREASE CONVECTION COVERAGE IN THE GRIDS, MENTION HEAVY
RAIN, AND ISSUE A FLASH FLOOD WATCH THROUGH 11 PM. PRECIPITABLE
WATER ALREADY NEAR ONE INCH, WITH MOISTURE ADVECTION CONTINUING
AS EVIDENCED BY CUMULUS CLOUD STREETS FROM SOUTHERN NEVADA.
COUPLED WITH WEAK FLOW OF 10 MPH OR LESS, AND WEAK CORFIDI
VECTORS, FLASH FLOODING THREAT WILL CONTINUE INTO THE EVENING. A
FEW, MOSTLY DRY, LIGHTNING STRIKES MAY WORK THEIR WAY AS FAR NORTH
AS THE RUBY MOUNTAINS THROUGH TONIGHT, BUT OTHERWISE NORTHERN
NEVADA WILL REMAIN MOSTLY CLEAR QUIET AND DRY THROUGH WEDNESDAY
MORNING.

WEDNESDAY...MOISTURE AND INSTABILITY ARE FURTHER RESTRICTED TO
MAINLY NYE COUNTY, WHERE SCATTERED THUNDERSTORMS WILL REDEVELOP
QUICKLY LATE WEDNESDAY MORNING. PW PERSISTS NEAR ONE INCH IN NYE
COUNTY, SO MORE LOCALLY HEAVY RAIN IS LIKELY FROM GABBS TO
TONOPAH, FROM MANHATTAN TO DUCKWATER. ELSEWHERE, DRY STABLE AIR
WILL TAKE CHARGE OVER THE REST OF THE ZONES, WITH DRY QUIET
WEATHER. HIGH PRESSURE WEAKENS SOME MORE, WITH HEIGHTS AND
THICKNESS LOWERING, ALLOWING MAX TEMPS TO HOLD IN THE LOWER 90S
IN SOME VALLEYS.

THURSDAY...MOISTURE AND INSTABILITY RETURN TO MUCH OF NEVADA, AT
LEAST TO SOME EXTENT, ESPECIALLY ACROSS THE WESTERN ZONES.
INCREASED THUNDERSTORM COVERAGE IN THE GRIDS, MAINLY ACROSS
CENTRAL AND NW NEVADA. LITTLE IF ANY CHANGES EXPECTED IN MAX TEMPS
FROM WEDNESDAY'S READINGS.

TURNER

.LONG TERM...THURSDAY NIGHT THROUGH NEXT TUESDAY. HIGH PRESSURE WILL
CONTINUE TO DOMINATE THE GREAT BASIN THROUGH THE LONG TERM PERIOD.
A SHORT WAVE APPROACHING THE PACIFIC NORTHWEST TOWARD THE END OF
THE LONG TERM PERIOD TEMPORARILY SUPPRESSES THE RIDGE TO THE FOUR-
CORNERS AREA BEFORE IT REBOUNDS BACK TO THE WEST EARLY NEXT WEEK.
THE THREAT OF SHOWERS AND THUNDERSTORMS ARE EXPECTED DAILY FOR
MUCH OF THE CWA FRIDAY INTO SUNDAY BEFORE A SOUTHWEST FLOW OF
DRIER RETURNS FOR LATE SUNDAY INTO EARLY NEXT WEEK. TEMPERATURES
WILL REMAIN ABOVE NORMAL THROUGH THE PERIOD WITH HIGHS MOSTLY IN
THE 90S AND LOWS IN THE 50S AND 60S.

&&

.AVIATION...THUNDERSTORMS WILL CONTINUE TO BREAK OUT MAINLY SOUTH OF
HIGHWAY 50 IN CENTRAL NEVADA THROUGH THIS EVENING...AFFECTING KTPH
AND KELY. KEKO WILL SEE GUSTY NORTHWEST WINDS INTO THIS EVENING. THE
THUNDERSTORM THREAT WILL REDEVELOP MAINLY SOUTH OF HIGHWAY 50
WEDNESDAY AFTERNOON AND EVENING.

&&

.FIRE WEATHER...SCATTERED TO NUMEROUS THUNDERSTORMS WILL CONTINUE
THROUGH THIS EVENING ACROSS FWZ 455 AND 457, WITH A FEW EXTENDING
NORTHWARD TO SE FWZ 454 AND SE FWZ 470. WIDESPREAD LIGHTNING IN
PROGRESS ACROSS FWZ 457 AS OF THIS WRITING, WITH LAL OF 5. SLOW
STORM MOVEMENT AND RICH MOISTURE WILL KEEP MOST STORMS WET THROUGH
THIS EVENING ACROSS CENTRAL NEVADA, WITH PERHAPS A FEW DRY
LIGHTNING STRIKES PERHAPS AS FAR NORTH AS THE RUBY MOUNTAINS.
LOCALLY HEAVY RAIN AND FLOODING POSSIBLE IN FWZ 455 AND 457
THROUGH 11 PM.

WEDNESDAY...DRIER MORE STABLE AIR TAKES OVER MUCH OF THE FIRE
DISTRICT, FOR DRY QUIET WEATHER. MOISTURE AND INSTABILITY WILL BE
RESTRICTED TO FWZ 457 WEDNESDAY, WHERE SCATTERED CONVECTION WILL
REDEVELOP BY LATE WEDNESDAY MORNING. ENHANCED LAL AND LOCALLY
HEAVY RAIN AGAIN EXPECTED IN AND NEAR FWZ 457 WEDNESDAY
AFTERNOON/EVENING. NORTHERN NEVADA WILL REMAIN DRY AND QUIET WITH
A NW BREEZE OF 10-15 MPH.

THURSDAY...MOISTURE AND INSTABILITY RETURN TO MUCH OF THE FIRE
DISTRICT, WITH THE HIGHEST COVERAGE OF THUNDERSTORMS EXPECTED
ACROSS THE WESTERN ZONES. LAL OF 3-4 ACROSS CENTRAL NEVADA, WITH
