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 00:00Z, 2.5 hours before the alert went out and 123 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
258 PM MDT MON JUL 17 2006

.SHORT TERM...
(TONIGHT AND TUESDAY)

HEALTHY NORTHERLY SURGE HAS PUSHED THROUGH MAJORITY OF THE
SOUTHEAST COLORADO PLAINS...WHICH SPARKED SOME THUNDERSTORMS
EARLIER TODAY OVER PORTIONS OF TELLER COUNTY AND CURRENTLY NOTING
STORMS OVER PORTIONS OF THE WESTERN 1/3 OF CWFA.

FRONTAL PASSAGE HAS TEMPERED MAXIMUM TEMPERATURES SLIGHTLY
TODAY...HOWEVER STILL NOTING MID-AFTERNOON TEMPERATURES IN THE
97F TO 99F RANGE AT PUEBLO...LA JUNTA...LAMAR AND SPRINGFIELD.

WITH BRIEF INFLUX OF ATMOSPHERIC MOISTURE...THANKS TO FRONT...HAVE
BUMPED POPS UP TO THE LOW SCATTERED CATEGORY TONIGHT FROM THE I-25
CORRIDOR WESTWARD...WHILE KEEPING ISOLATED POPS OVER THE REMAINDER
OF THE PLAINS.

ON TUESDAY...EXPECT A RETURN/CONTINUATION OF ABOVE CLIMATOLOGICAL
AVERAGE MAXIMUM TEMPERATURES FOR THE MAJORITY OF THE CWFA IN
COMBINATION WITH LOW GRADE POPS...CONCENTRATED MAINLY OVER THE
HIGHER TERRAIN. THANKS SURROUNDING OFFICES FOR
COORDINATION/COLLABORATION.

.LONG TERM...
(TUESDAY NIGHT THROUGH MONDAY)

MAIN CHANGES TO THE NDFD WERE TO DECREASE THE TEMPS A FEW DEGREES
FOR THE WEEKEND AND INCREASE THE CHANCE OF PRECIP UP A BIT. GUIDANCE
CONTINUES TO PAINT A COOLING TREND THIS WEEKEND AND I CONTINUED TO
TREND THE MET VARIABLES TO THIS SOLUTION.

LATEST GFS CONTINUES TO SHOW RIDGE RETROGADING WEST AND AMPLIFYING
AS TROUGH DIGS OVER EASTERN 1/3RD OF NATION. THIS SHOULD ALLOW COOLER
CANADIAN AIR TO MOVE INTO THE REGION STARTING LATER ON FRIDAY AND
LASTING THROUGH THE WEEKEND. IF GUIDANCE IS A PERFECT PROG...THEN
THINGS WILL HAVE TO BE TRENDED DOWN EVEN COOLER & WETTER...BUT I DID
NOT WANT TO JUMP ON THIS SOLUTION JUST YET.

OTHER CHANGES I MADE WERE TO WED AND THU...THESE WERE PRIMARILY
FINE TUNING CHANGES TO THE ONSET OF PRECIP. OTHERWISE NO OTHER
CHANGES WERE MADE TO THE GRIDDED DATABASE. /HODANISH
