The Pueblo radar (KPUX), 18 km from the middle of the area, began a volume at 23:13 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 severe thunderstorm 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

Denver, CO (KDNR), launched 12:00Z, 11.2 hours before the alert went out and 193 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 PUEBLO CO
316 PM MDT THU JUL 7 2011

.SHORT TERM...
(TODAY AND TONIGHT)

...LOCALLY HEAVY RAIN THIS AFTERNOON AND EVENING...

MAIN CONCERN FOR THE SHORT TERM WILL BE THE POTENTIAL FOR SOME LOCALLY
HEAVY RAINFALL LATE THIS AFTERNOON THROUGH EARLY EVENING. DEWPOINTS THIS
AFTERNOON ARE HOLDING IN THE 50S...WITH A FEW 60S NR THE KS BORDER. EXPECT
A COUPLE ROUNDS OF STORMS DEVELOPING E OF THE MTNS AND MOVING EWD
OVR THE PLAINS. RAPID UPDATE RUC AND WRF MODELS ARE SHOWING GOOD STORM
COVERAGE TODAY...ALTHOUGH HIGHEST PROBABILITY OF PRECIP WILL BE OVR
THE I-25 CORRIDOR FROM KPUB NWD. HAVE MADE SOME MINOR ADJUSTMENTS TO
POPS...TO INDICATE LIKELY POPS SPREADING EWD FROM THE I-25 CORRIDOR LATE
THIS AFTERNOON...TO THE SERN PLAINS IN THE EARLY EVENING HOURS. WILL
MAINTAIN SOME CHANCE POPS FOR ERN KIOWA AND PROWERS COUNTIES
OVERNIGHT. MAIN CONCERN TODAY WILL BE FOR SOME LOCAL FLOODING DUE TO
HEAVY RAIN...ALTHOUGH STORMS WILL BE MOVING FAIRLY WELL SO URBAN
AREAS AND BURN SCARS WILL BE THE MAIN CONCERNS. SOME ISOLD
MARGINALLY SVR HAIL ALSO POSSIBLE.

STORM COVERAGE ON FRI DOES NOT LOOK AS WIDESPREAD AS IT DOES TODAY.
THE UPPER HIGH WILL BUILD ACROSS CENTRAL CO ON FRI...AND H7 TEMPS
WILL CLIMB INTO THE UPPER TEENS. EXPECT TEMPS OVR THE PLAINS TO
REACH THE MID 90S. A SHORT WAVE MOVING THROUGH N CO WILL BRING A
ROUND OF AFTERNOON STORMS TO MAINLY THE NRN ZONES. WITH BULK SHEARS
AROUND 30 KTS OR SO...A STRONG STORM OR TWO CANNOT BE RULED
OUT...PARTICULARLY OVR THE PALMER DVD LATE IN THE AFTERNOON. ROSE

.LONG TERM...
(FRIDAY NIGHT THROUGH THURSDAY)

EXPECT SCATTERED DIURNAL CONVECTION TO DIMINISH TOWARD SUNSET
FRIDAY EVENING...WITH BEST UPWARD MOTION SHIFTING NORTH AND EAST
OF THE AREA BY MIDNIGHT. WILL THUS END MOST POPS BY 06Z...THOUGH
WILL ALLOW A MENTION OF ISOLATED TSRA TO PERSIST THROUGH THE NIGHT
ALONG THE CONTINENTAL DIVIDE AS MODELS CONTINUE TO WRING OUT SOME
LIGHT QPF IN NEARLY SATURATED AIR MASS. STILL APPEARS SOME DRIER
AIR WORKS INTO THE AREA SATURDAY AS WESTERLY MID LEVEL FLOW
INCREASES SLIGHTLY. DOUBT WE'LL SHUT DOWN CONVECTION
COMPLETELY...THOUGH SUSPECT STORM COVERAGE IN NON-MOUNTAIN
LOCATIONS WILL BE ISOLATED AT BEST. WILL LIKELY SEE SOME HOTTER
TEMPS...NEAR 100F...APPEAR ON THE PLAINS SATURDAY
AFTERNOON...THOUGH MAV GUIDANCE LOOKS A LITTLE TOO HOT..ESPECIALLY
AROUND KPUB. WEAK BOUNDARY/UPSLOPE SURGE WILL BE SOMEWHERE OVER
THE PLAINS SATURDAY NIGHT/EARLY SUNDAY...BEFORE MIXING NORTHWARD
TO NEAR I-70 BY SUNDAY AFTERNOON. DEEPER MOISTURE WOULD THUS
APPEAR TO REMAIN JUST NORTH OF THE AREA...SO WILL RUN WITH ONLY
ISOLATED TO LOW END SCATTERED POPS AGAIN AREA-WIDE. EXPECT MAX
TEMPS TO REMAIN WITHIN A COUPLE DEGREES OF SATURDAY'S NUMBERS.

STILL APPEARS FAIRLY DEEP PUSH OF MOISTURE FROM THE SOUTH WILL
OCCUR FROM MON INTO WED...WITH PRECIP CHANCES INCREASING OVER MUCH
OF THE AREA...ESPECIALLY FROM I-25 WESTWARD. SOME CONCERN THAT
SUBSIDENCE AROUND THE UPPER LEVEL LOW WANDERING NORTH THROUGH
TEXAS MAY SUPPRESS TSRA OVER THE EASTERN PLAINS...SO WON'T HIT POPS
EAST OF I-25 TOO HARD YET. BY LATE WED INTO THU...MEDIUM RANGE
MODELS BEGIN TO LIFT THE WEST COAST TROUGH NORTHEASTWARD...WITH
STRENGTHENING SOUTHWEST FLOW OVER COLORADO POTENTIALLY TAPPING
THE DRY AIR OFF THE CALIFORNIA COAST AND SUPPRESSING CONVECTION BY
THE END OF THE WEEK. STILL TOUGH TO REMOVE PRECIP CHANCES THIS
TIME OF YEAR...SO WILL MAINTAIN ISOLATED MENTION MOST AREAS.
--PETERSEN

&&

.AVIATION...MAIN AVN CONCERNS WILL BE THE POTENTIAL FOR TS MOVING
ACROSS THE KPUB AND KCOS SITES THIS AFTERNOON. AS INDICTED IN
TAFS...BEST CHANCE OR TIME FRAME FOR STORMS WILL BE SLIGHTLY
EARLIER FOR KCOS...FROM ABOUT 20Z THROUGH 00-01Z...WHILE AT KPUB
BEST WINDOW FOR TS WILL BE FROM AROUND 22-02Z. HEAVY RAINFALL
COULD BRING SOME BRIEF MVFR-IFR CONDITIONS. SOME SMALL HAIL ALSO
POSSIBLE ALONG WITH SOME GUSTY WINDS FROM THE W TO NW. DEPENDING
ON EXTENT OF RAINFALL THIS EVE...COULD SEE SOME PATCHY MVFR CIGS
OR EVEN SOME BR DEVELOP EARLY FRI MORNING OVR THE LOWER ARKANSAS
VALLEY AND PIKES PEAK REGION. STORMS OVR THE SAN LUIS VALLEY AND
CONTDVD WILL BE ISOLD TO SCT THIS AFTERNOON AND EVENING. ROSE

CENTRAL...SOUTH CENTRAL AND SOUTHEAST COLORADO.

.DAY ONE...THIS AFTERNOON AND TONIGHT

PERSISTENT MOISTURE OVER THE REGION TODAY WILL RESULT IN ANOTHER
ROUND OF SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS.
THUNDERSTORMS WILL BE MOST NUMEROUS IN AND NEAR THE
MOUNTAINS...ACROSS THE PIKES PEAK REGION...AND ALONG THE
INTERSTATE 25 CORRIDOR. THE MAIN THREAT FROM THUNDERSTORMS WILL BE
LOCALLY HEAVY RAINFALL AND FREQUENT LIGHTNING. ONE OR TWO STORMS
COULD BRIEFLY BECOME STRONG TO SEVERE...WITH HAIL UP TO 1 INCH IN
DIAMETER POSSIBLE IN AND NEAR THE SOUTHEAST MOUNTAINS. AS STORMS
MOVE OFF INTO THE I-25 CORRIDOR AND SOUTHEAST PLAINS...HEAVY RAIN
AND LOCALIZED WIND GUSTS TO AROUND 60 MPH WILL BE POSSIBLE WITH
THE STRONGER STORMS.

RAINFALL RATES OF UP TO 1 INCH IN HALF AN HOUR WILL BE POSSIBLE
WITH THE STRONGER STORMS...AND COULD CAUSE SOME LOCALIZED FLASH
FLOODING ACROSS URBAN AREAS...ESPECIALLY ACROSS COLORADO SPRINGS
WHERE THE GROUND IS ALREADY WET FROM RAIN RECEIVED OVER THE PREVIOUS
FEW DAYS. LOCALIZED FLASH FLOODING WILL ALSO BE POSSIBLE IN AND NEAR
THE WILD FIRE BURN SCARS WHERE SOILS WILL BE PRONE TO RAPID RUN OFF
AND MUD AND ASH FLOWS.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED FROM FRIDAY

HOWEVER...A FEW STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE
ACROSS THE EASTERN MOUNTAINS...THE I-25 CORRIDOR AND PORTIONS OF
THE SOUTHEASTERN COLORADO PLAINS ON FRIDAY. THE MOST INTENSE
STORMS WILL BE CAPABLE OF PRODUCING HAIL UP TO THE SIZE OF
QUARTERS AS WELL AS WIND GUSTS AROUND 60 MPH. THE HIGHEST RISK FOR
SEVERE STORMS WILL BE EAST OF INTERSTATE 25 AND NORTH OF HIGHWAY 50
FRIDAY AFTERNOON. IN ADDITION... LOCALLY HEAVY RAINFALL COULD
CAUSE LOCALIZED FLASH FLOODING...ESPECIALLY ACROSS BURN SCAR AREAS
WHERE SOILS WILL BE PRONE TO RAPID RUN OFF AS WELL AS MUD AND ASH
FLOWS.
