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 (KDEN), launched 00:00Z, 0.5 hours before the alert went out and 200 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 CHEYENNE WY
555 PM MDT SUN JUL 13 2014

.UPDATE...
ISSUED AT 543 PM MDT SUN JUL 13 2014

QUICK UPDATE TO THE GRIDS TO ADJUST PCPN TRENDS FOR THE REST OF
THE EVENING. LATEST WATER VAPOR SATELLITE LOOP SHOWS THE STRONG
MIDLVL SHORTWAVE RESPONSIBLE FOR THE EARLIER STRONG TO SEVERE
CONVECTION HAS MOVED EAST OF THE CWA. A MOIST AND UNSTABLE AIR
MASS REMAINS IN PLACE OVER THE HIGH PLAINS WITH WIDESPREAD DEW
POINTS IN THE MID 50S AND SPC MESOANALYSIS CAPES AROUND 1500 TO
2000 J/KG. KCYS RADAR STILL SHOWS SOME ISOLATED CONVECTION OUT
THERE...AND WITH TOWERING CUMULUS STILL ON VISIBLE SATELLITE DO
BELIEVE THERE IS STILL POTENTIAL FOR A FEW STORMS. COULD ALSO SEE
SOME NEW TSTMS DEVELOP ALONG PREVIOUS OUTFLOW. NOT EXPECTING
THINGS TO BE AS WIDESPREAD AS EARLIER...SO CUT BACK POPS INTO THE
ISOLATED CATEGORY FOR THE REST OF THE EVENING.

&&

.SHORT TERM...(THIS EVENING THROUGH TUESDAY NIGHT)
ISSUED AT 337 PM MDT SUN JUL 13 2014

CONVECTION GRADUALLY INCREASING ACROSS SOUTHEAST WYOMING THIS
AFTERNOON AND THIS WILL MOVE EAST OVER THE NEBRASKA PANHANDLE THIS
EVENING. HEAVY RAIN CONTINUES TO BE THE MAIN THREAT FROM STRONGER
STORMS WITH MOST LIKELY AREA FOR THIS BEING EAST OF THE MTNS INTO
THIS EVENING. ANY FLOODING THAT MIGHT OCCUR SHOULD REMAIN RATHER
LOCALIZED. SOME HAIL THREAT STILL THERE AS WELL THOUGH UPPER
SUPPORT NOT ALL THAT GREAT. ACTIVITY WILL DECREASE OVERNIGHT
THOUGH SOME MAY HANG ON OVER NORTHEAST PARTS OF THE CWA THROUGH
THE NIGHT.

SIMILAR SCENARIO EXPECTED FOR SATURDAY AS SFC UPSLOPE FLOW BEHIND
A WEAK SFC FRONT THAT WILL PASS ACROSS DURING THE DAY ALLOWS FOR
REDEVELOPMENT OF CONVECTION. INSTABILITY NOT PROGGED TO BE AS
GREAT THOUGH SO ACTIVITY LIKELY TO BE MORE SHOWERY IN NATURE.
TEMPS JUST A LITTLE COOLER OVER THE PLAINS. ACTIVITY WILL DIE OUT
SAT EVENING. A STRONGER FRONT WILL THEN PUSH SOUTH ACROSS THE CWA
SUNDAY WITH SCTD SHOWERS AND A FEW STORMS ONCE AGAIN.

.LONG TERM...(WEDNESDAY THROUGH SUNDAY)
ISSUED AT 337 PM MDT SUN JUL 13 2014

A WEAK SHORTWAVE IS EXPECTED TO EXIT THE AREA WEDNESDAY EVENING
WHICH WILL CAUSE SHOWERS AND THUNDERSTORMS TO GRADUALLY EXIT THE
AREA EAST OF THE LARAMIE RANGE BY AROUND MIDNIGHT. MEANWHILE...THE
UPPER LEVEL RIDGE WILL CONTINUE TO BUILD OVER THE ROCKIES BEGINNING
THURSDAY AND CONTINUING THROUGH THE WEEKEND. SMALL DISTURBANCES ARE
PROGGED TO MOVE THROUGH THE EASTERN PERIPHERY OF THIS RIDGE THURSDAY
AND FRIDAY WHICH MAY TRIGGER SOME CONVECTION EAST OF THE LARAMIE
RANGE. THE NEXT STRONG UPPER LEVEL TROF IS PROGGED TO MOVE INTO
BRITISH COLUMBIA AND SASKATCHEWAN THIS WEEKEND WHICH WILL TEND TO
AMPLIFY THE RIDGE OVER THE REGION WHICH WILL RESULT IN WARMING
TEMPERATURES AND SOMEWHAT DRIER CONDITIONS.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY MORNING)
ISSUED AT 1147 AM MDT SUN JUL 13 2014

SCATTERED SHOWERS AND THUNDERSTORMS ARE PROGGED TO DEVELOP ALONG
THE LARAMIE RANGE THIS AFTERNOON AND MOVE SOUTHEAST AT 15 TO 20

OF THE ACTIVITY WILL IMPACT THE CYS AND LAR TAF SITES THIS
AFTERNOON. OTHERWISE...CLEARING SKIES ARE ANTICIPATED THIS
EVENING WITH MAINLY VFR CONDITIONS EXPECTED.

&&

ISSUED AT 337 PM MDT SUN JUL 13 2014
CONCERNS TO REMAIN LOW INTO NEXT WEEK WITH WEATHER CONDITIONS
