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
Flgstf/Belemont, AZ (KFGZ), launched 12:00Z, 10.0 hours before the alert went out and 188 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, Jan 21, 9:27 AM MST, 5 hours 35 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
827 AM PST THU JAN 21 2010
.SYNOPSIS...THE FINAL STORM IN THIS SERIES WILL BRING ONE MORE ROUND
OF RAIN AND SNOW TO MUCH OF THE REGION LATE THIS MORNING THROUGH
LATE THIS EVENING. SHOWERS WILL LINGER FRIDAY AND SATURDAY...WITH
LOCALLY HEAVY SNOW SHOWERS POSSIBLE IN THE MOUNTAINS FRIDAY.
GENERALLY DRY WEATHER IS EXPECTED SUNDAY AND MONDAY...THEN ANOTHER
STORM SYSTEM WILL AFFECT THE AREA TUESDAY AND WEDNESDAY.
&&
.UPDATE...A WINTER WEATHER ADVISORY HAS BEEN ISSUED FOR THE
MORONGO BASIN AND EASTERN MOJAVE DESERT ZONES THROUGH MIDDAY. SNOW
LEVELS WERE AROUND 2500 TO 3000 FEET AND WE RECEIVED SEVERAL
REPORTS OF ACCUMULATING SNOW AS LOW AS 3300 FEET. THE SNOW WILL
NOT LAST LONG AS WARMER AIR MOVES IN FROM THE SOUTH AND CAUSES
SNOW LEVELS TO RISE BY MIDDAY AND THIS WILL CHANGE ALL OF THE SNOW
OVER TO RAIN. UPDATED GRIDS AND ZONES HAVE BEEN SENT FOR THIS.
&&
.PREV DISCUSSION... /ISSUED 346 AM PST THU JAN 21 2010/
.SHORT TERM...SATELLITE SHOWS HIGH CLOUDS ENHANCING ALONG AND
SOUTHEAST OF I-15 IN LEFT EXIT REGION OF 185 KT JET STREAK
APPROACHING THE PACIFIC COAST ALONG 30N. STRONG CIRCULATION NEAR 35N
128W WITH LARGE AND EXPANDING ENHANCED CLOUD SHIELD AHEAD OF IT IS
THE CABOOSE IN THIS TRAIN. AS THIS STORM RIDES THE JET STREAK INTO
THE COAST...AN AREA OF TREMENDOUS DIFFLUENCE ALOFT WILL TRAVERSE OUR
CWFA THIS AFTERNOON AND EVENING. THIS WILL SUPPORT WIDESPREAD RAIN
AND SNOW YET AGAIN. ASSOCIATED 980 MB SURFACE LOW WILL LIFT NORTH
THROUGH LAS VEGAS...SUPPORTING STRONG SOUTH WINDS OVER MOHAVE COUNTY
THIS AFTERNOON AND EVENING...SO THE WIND ADVISORY REMAINS IN PLACE.
THE BIGGEST FLY IN THE OINTMENT IS WHERE THE HEAVY RAIN WILL SET UP
THIS AFTERNOON AND EVENING. THE 00Z GFS AND NAM12 BOTH SHIFTED THE
AXIS A HUNDRED MILES OR MORE EAST OF WHERE THEY ADVERTISED IT
YESTERDAY. THE 06Z GFS LOOKS LIKE THE 00Z RUN...BUT THE 06Z NAM12
HAS OSCILLATED BACK TO THE WEST. THE LOCATION OF THIS HEAVY RAIN
AREA WILL MAKE A LOT OF DIFFERENCE IN THE RIVER CRESTS ON FRIDAY.
WITH CRITICAL UNCERTAINTY SO CLOSE TO THE EVENT...FELT THE PRUDENT
COURSE WAS TO LEAVE THE FLOOD WATCH AS IS AND WAIT FOR REALITY TO
SHOW ITSELF BEFORE UPGRADING OR CANCELING. ALSO MADE NO CHANGES TO
THE ONGOING WINTER WEATHER ADVISORY AND WINTER STORM WARNINGS. ONE
CONCERN HERE IS THE HUGE FIELD OF OPEN CELL CUMULUS SEEN OVER THE
PACIFIC IN THE MAIN TROUGH. THIS AIRMASS WILL BE OVER OUR CWFA ON
FRIDAY...AND WILL SUPPORT SIGNIFICANT INSTABILITY SHOWERS. WINTER
WEATHER ADVISORIES MAY BE NEEDED FOR THE MOUNTAIN AREAS AGAIN ON
FRIDAY...AND FLURRIES/LIGHT SNOW SHOWERS MAY BE SEEN AT THE LOWER
ELEVATIONS AS WELL. THE MODELS AGREE ON DELAYING THE EVENTUAL
PASSAGE OF THE TROUGH...SO KEPT SOME LOW CHANCE POPS GOING THROUGH
SATURDAY AFTERNOON IN THE HIGHER TERRAIN BEFORE FINALLY DRYING IT
OUT COMPLETELY SATURDAY NIGHT.
.LONG TERM...SUNDAY MORNING THROUGH THURSDAY...MODELS IN FAIRLY GOOD
AGREEMENT IN THE EXTENDED WITH THE MAJOR DETAILS WITH DIFFERENCES IN
THE DEPTH AND TRACK OF THE NEXT TROUGH TO MOVE THROUGH IN THE
TUESDAY TO WEDNESDAY TIMEFRAME. A RIDGE OVER THE AREA SUNDAY TO
START OUT THE EXTENDED. THE NEXT SYSTEM BEGINS TO MAKE ITSELF FELT
BY MONDAY WITH A MOISTURE PLUME IMPACTING THE SIERRA IN THE
SOUTHWEST FLOW AHEAD OF IT. RESTRICTED POPS TO THE SIERRA THEN AND
THEN SPREAD THEM OUT OVER THE REST OF THE CWA AS THE TROUGH
APPROACHED AND MOISTURE/LIFT OVERSPREAD THE AREA MONDAY NIGHT AND
INTO TUESDAY. THE ECMWF AND GEM HAD A DEEPER SYSTEM THAN THE GFS AS
IT DROPPED IN AND THROUGH THE CWA. IN EITHER CASE THE POPS WOULD
STILL BE AS WIDESPREAD AS FORECAST BUT THE GFS SCENARIO WOULD HAVE
THE NUMBERS LOWER AND WENT WITH A BLEND OF THE TWO IDEAS. WEDNESDAY
WILL SEE A WEST TO EAST CLEARING AD THE SYSTEM DEPARTS AND BY
THURSDAY THERE IS GOOD AGREEMENT ON HAVING A SHORTWAVE RIDGE OVER
THE AREA.
&&
.AVIATION...FOR MCCARRAN...A BIT OF A REPRIEVE FROM THE ACTIVE
WEATHER THIS MORNING BEFORE ANOTHER ROUND OF RAIN MOVES IN THIS
AFTERNOON AND INTO TONIGHT. THIS SHOULD BE THE HEAVIEST RAINS SEEN
THIS WEEK. EXPECT RAIN TO TAPER OFF AROUND MIDNIGHT TONIGHT. IT IS
NOT ENTIRELY OUT OF THE QUESTION TO SEE ISOLATED THUNDERSTORMS IN
THE AREA LATE THIS AFTERNOON AND INTO THE EARLY EVENING WITH THE
BEST CHANCES BEING OVER LOCAL MOUNTAINS AND IN THE DAGGETT CORRIDOR.
EARLY FRIDAY MORNING WILL SEE ANOTHER BREAK BEFORE ANOTHER SHOT AT
RAIN AND A CHANCE FOR THUNDERSTORMS IN THE AREA IN THE AFTERNOON.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...THE NEXT STORM WILL HAS BEGUN IMPACTING THE AREA THIS
MORNING AND WILL TRANSITION OVER THE AREA THROUGH FRIDAY MORNING.
EXPECT WIDESPREAD RAIN AND SNOW THROUGH THE ENTIRE REGION WITH LOW
CEILINGS AS THIS SYSTEM SHIFTS EAST. ALTHOUGH A BRIEF BREAK WILL BE
SEEN EARLY FRIDAY...EXPECT MOUNTAIN OBSCURATIONS THROUGH MUCH OF
FRIDAY MORNING. THUNDERSTORMS ARE A POSSIBILITY PRIMARILY SOUTH OF
AN INTERSTATE 15 LINE THIS AFTERNOON AND EARLY EVENING.
&&
.HYDROLOGY....HEAVY RAIN AND POSSIBLY MELTING SNOW PACK TODAY COULD
PUSH SOME RIVERS TO OR ABOVE FLOOD STAGE TOMORROW. THE FORECAST FOR
THE BIG SANDY RIVER NEAR WIKIEUP IS A VERY RAPID RISE ABOVE THE
FLOOD STAGE OF 16 FEET EARLY FRIDAY MORNING...A CREST NEAR 18.5 FEET
FRIDAY MORNING...THEN A RAPID FALL BACK BELOW FLOOD STAGE BY NOON.
THE MUDDY RIVER NEAR GLENDALE IS FORECAST TO RISE RAPIDLY FRIDAY
MORNING...CREST NEAR THE FLOOD STAGE OF 15 FEET FRIDAY
AFTERNOON...THEN RAPIDLY FALL. THE PRECIPITATION FORECAST IS THE BIG
QUESTION AS THE MODELS CANNOT AGREE ON WHERE THE HEAVIEST PRECIP
WILL FALL. WITH THAT IN MIND...KEPT THE FLOOD WATCH INTACT AND WILL
WATCH TO SEE HOW REALITY UNFOLDS.
