The Pueblo radar (KPUX), 30 km from the middle of the area, began a volume at 23:09 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

Grand Junction, CO (KGJT), launched 12:00Z, 11.2 hours before the alert went out and 381 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, Aug 18, 3:58 PM MDT, 1 hour 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
358 PM MDT SUN AUG 18 2013

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 330 PM MDT SUN AUG 18 2013

WILL KEEP DISCUSSION RELATIVELY BRIEF DUE TO ONGOING ACTIVITY.
MAIN METEOROLOGICAL ISSUES CONTINUE TO BE POPS AND TEMPERATURES.

CWFA CURRENTLY NOTING MOSTLY CLOUDY CONDITIONS WESTERN 2/3RDS WITH
MOSTLY SUNNY CONDITIONS EASTERN 1/3 OF THE FORECAST DISTRICT. IN
ADDITION...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS...SOME
QUITE INTENSE ALSO HAVE BEEN EXPERIENCED OVER THE WESTERN 2/3RDS.

FOR EXAMPLE...1 INCH DIAMETER HAIL WAS NOTED 7 MILES TO THE SOUTH
OF CALHAN IN EL PASO COUNTY AT 230 PM MDT AND A FLASH FLOOD
WARNING IS IN EFFECT FOR PORTIONS OF THE WEST FORK BURN COMPLEX IN
MINERAL COUNTY UNTIL 7 PM MDT...ESPECIALLY SOUTHERN SECTIONS OF
THE WEST FORK BURN SCAR.

OUTSIDE OF THE SHOWER AND THUNDERSTORM ACTIVITY...GENERALLY LIGHT
WINDS IN COMBINATION WITH NEAR TO SLIGHTLY ABOVE SEASONAL
MID-AUGUST TEMPERATURES ARE BEING REPORTED.

LATEST COMPUTER SIMULATIONS...REAL-TIME DATA AND FORECAST MODEL
SOUNDINGS SUGGEST THAT SOMEWHAT ELEVATED ATMOSPHERIC MOISTURE
VALUES CONTINUE OCCUR OVER THE CWFA INTO MONDAY AFTERNOON...WITH
PRECIPITABLE WATER VALUES OVER THE INTERSTATE 25 CORRIDOR AROUND
0.85 INCHES AT TIMES OVER THE INTERSTATE 25 CORRIDOR.
ALSO...CENTER OF UPPER RIDGE REMAINS CENTERED OVER THE 4-CORNERS
REGION INTO MONDAY AFTERNOON.

FOR SENSIBLE WEATHER TONIGHT...WILL CONTINUE WITH ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS INTO THIS EVENING(A FEW QUITE
STRONG TO POSSIBLY SEVERE AT TIMES). PRECIPITATION CHANCES THEN
DECREASE AROUND MIDNIGHT.

THEN FOR MONDAY...EXPECT ANOTHER ROUND OF PRIMARILY ISOLATED TO
SCATTERED AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS...SOME
POTENTIALLY STRONG AND CAPABLE OF PRODUCING LOCALLY HEAVY
RAINFALL. AS ALWAYS...AREA BURN SCARS WILL CONTINUE TO BE
MONITORED IN CASE A STRONGER STORM DEVELOPS IN A BURN SCARS
VICINITY.

FINALLY...AS HAS BEEN THE CASE THE PREVIOUS FEW DAYS...ABOVE
SEASONAL TEMPERATURES SHOULD BE NOTED AGAIN ON MONDAY IN
COMBINATION WITH BASICALLY LOW-GRADE GRADIENT WINDS.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 330 PM MDT SUN AUG 18 2013

NOT MUCH CHANGE WITH ONGOING LONG TERM FORECAST. MONSOON PLUME IS
NOW OVER MTNS AND EXPECT IT TO REMAIN OVER THE MTNS INTO NEXT
WEEKEND. THIS WILL KEEP SCATTERED TO LIKELY POPS...SOME HEAVY...OVER
THE CONTDVD. SCTD POPS WILL OCCUR OVER THE REMAINDER OF THE MTNS
WHILE THE VALLEYS WILL HAVE SCTD TO ISOLD POPS. ALONG THE I-25
CORRIDOR...ISOLD POPS WILL BE POSSIBLE DURING THE MID TO LATE
AFTERNOON TIME PERIOD. THE REST OF THE PLAINS WILL REMAIN GENERALLY
DRY.

THE ONLY EXCEPTION TO THE ABOVE WILL BE LATE WED INTO THU. A WEAK
FRONT WILL MOVE DOWN LATE AFTERNOON WED. THIS ADDED LLVL SURGE WILL
ENHANCE THE POPS ALONG THE I-25 CORRIDOR REGION WED EVENING AND LAST
INTO THURSDAY. THERE WILL ALSO BE A SLIGHT CHANCE OF POPS ACROSS ALL
OF THE PLAINS LATE WED AND THU AFTERNOON.

ALL BURN SCARS WILL BE UNDER RISK FOR FLASH FLOODING GIVEN THAT THE
PLUME IS NOW OVER US AND STORM MOTIONS WILL BE SLOW.

TEMPS THROUGH THE PD ON THE PLAINS WILL RUN ABOUT 3 TO 6F ABOVE
NORMAL. \/HODANISH

.AVIATION...ISSUED AT 330 PM MDT SUN AUG 18 2013

VFR CONDITIONS ARE EXPECTED TO CONTINUE OVER THE KALS...KCOS AND
KPUB TAF SITES THROUGH TONIGHT AS UPPER RIDGING REMAINS OVER THE
FORECAST DISTRICT. ENOUGH ATMOSPHERIC MOISTURE IS IN PLACE TO
ALLOW ISOLATED THUNDERSTORMS OVER THE TAFS UNTIL AROUND 03Z
MONDAY.
