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, 2.1 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.

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cheyenne, WY wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 26, 1:38 PM MDT, 6 hours 25 minutes earlier.
Area forecast discussion, Jun 26, 1:38 PM MDT, 6 hours 25 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 138 PM MDT SUN JUN 26 2011 .SHORT TERM...TONIGHT THROUGH TUESDAY. TONIGHT...CONVECTIVE PARAMETERS LOOK QUITE FAVORABLE FOR A DECENT SEVERE WEATHER EVENT THIS AFTERNOON AND EVENING NORTH OF A CASPER TO SIDNEY LINE...AND ESPECIALLY ACROSS THE WESTERN NEBRASKA PANHANDLE... PARTICULARLY THE SOUTHERN COUNTIES OF THE PANHANDLE. AT 1 PM...THE COLD FRONT WAS POISED JUST NORTH OF CONVERSE AND NIOBRARA COUNTIES WITH TEMPERATURES IN THE 50S AND 60S AT SHERIDAN AND GILLETTE. ACROSS OUR COUNTIES...TEMPERATURES WERE IN THE 70S AND 80S. LOW LEVEL MOISTURE HAD MIXED OUT WEST OF A DOUGLAS TO CHEYENNE LINE WITH 1 PM DEWPOINTS IN THE 20S AND 30S AND SOME LOWER 40S...WHILE IN THE MORE SOUPY LOW LEVEL AIRMASS...DEWPOINTS WERE MAINLY THE 50S AND 60S EAST OF A DOUGLAS TO CHEYENNE LINE. IMPRESSIVE MID 60S DEWPOINTS AT ALLIANCE AND SIDNEY AT 1 PM. WE HAD ONE WARNING VERIFIED THIS MORNING AROUND 9 AM WHEN A LINE OF SEVERE THUNDERSTORMS MOVED SOUTHEAST ACROSS DAWES COUNTY NEBRASKA AND CHADRON PRODUCING 1.25 INCH DIAMETER HAIL. THESE STORMS LIKELY LEFT OUTFLOW BOUNDARIES WHICH WILL HELP CONVECTIVE INITIATION THIS AFTERNOON ALONG WITH OTHER FACTORS. AS A SHORTWAVE TROUGH ALOFT PROPAGATES EASTWARD ACROSS MONTANA AND NORTHERN WYOMING THIS AFTERNOON...THE ASSOCIATED COLD FRONT WILL SLIDE SLOWLY SOUTHWARD ACROSS OUR COUNTIES THIS EVENING. WITH PROGGED INSTABILITY AND WIND SHEAR...AND ADEQUATE FRONTAL LIFTING NEAR PEAK HEATING...EXPECTING SCATTERED TO NUMEROUS THUNDERSTORMS TO DEVELOP THIS AFTERNOON INITIALLY ALONG A DOUGLAS TO CHADRON LINE...WITH STORMS DEVELOPING AND PROPAGATING SOUTHWARD ALONG THE SOUTHWARD MOVING COLD FRONT. DECENT LOW LEVEL MOISTURE... INSTABILITY...ALONG WITH PROGGED WIND SHEAR SUGGESTS THAT SOME OF THE STORMS THIS AFTERNOON AND EVENING IN THE STORM PREDICTION CENTER DAY ONE SLIGHT RISK AREA WILL BECOME SEVERE...PRODUCING LARGE HAIL AND DAMAGING WINDS. 850/700 MB THETA-E PROGS SHOW A WELL PRONOUNCED 850 MB THETA-E RIDGE AXIS FROM WESTERN NEBRASKA SOUTHEAST INTO NORTHERN KANSAS...WITH IMPRESSIVE THETA-E ADVECTION AND CONVERGENCE NOTED ACROSS THE KIMBALL AND SIDNEY AREAS...THUS BELIEVE THE GREATEST RISK FOR SEVERE THUNDERSTORMS WILL BE OVER THE CENTRAL AND SOUTHERN PANHANDLE COUNTIES THROUGH THIS EVENING WHERE LOW LEVEL CONVERGENCE WILL BE MAXIMIZED ALONG THE NORTHWEST TO SOUTHEAST ORIENTED INSTABILITY AXIS. STRONG TO SEVERE THUNDERSTORMS EXPECTED TO CONTINUE WELL INTO THE EVENING HOURS WITH COLD FRONTAL LIFTING AND IMPRESSIVE LOW LEVEL MOISTURE ADVECTION FEEDING THE THUNDERSTORMS ON SOUTHEAST WINDS. AN ISOLATED TORNADO NOT OUT OF THE QUESTION BASED ON HELICITY PARAMETERS AND PROGGED INSTABILITY...ESPECIALLY FROM CHADRON SOUTH TO SIDNEY. THUNDERSTORM CHANCES MUCH LESS WEST OF INTERSTATE 25 THIS EVENING WITH DRY LOW LEVELS. MONDAY...MORE QUIESCENT AND COOLER DAY ON TAP IN THE WAKE OF THE COLD FRONT AND WITH RIDGING ALOFT. 850/700 MB THETA-E RIDGE AXISES WILL LIE NORTH TO SOUTH ACROSS OUR WESTERN COUNTIES IN THE AFTERNOON. ISOLATED TO WIDELY SCATTERED THUNDERSTORMS ON TAP IN THE AFTERNOON MAINLY WEST OF INTERSTATE 25. FURTHER EAST...THE ATMOSPHERE WILL BE TOO STABLE TO SUPPORT THUNDERSTORM INITIATION. MONDAY NIGHT...LOW LEVEL RETURN SOUTHERLY WIND DEVELOP ALLOWING LOW LEVEL RETURN FLOW TO COMMENCE...AS HAPPENS QUITE QUICKLY IN SOUTHEAST WYOMING AND WESTERN NEBRASKA. THUS...THE ATMOSPHERE WILL LOAD UP AGAIN ON LOW LEVEL MOISTURE. TUESDAY...MORE TYPICAL SUMMERLIKE PATTERN PREVAILS WITH WEST SOUTHWEST FLOW ALOFT...500 MB HEIGHTS NEAR 588 DEKAMETERS...BRISK SOUTHERLY WINDS AT LOW LEVELS AND WARM MID LEVEL TEMPERATURES. IMPRESSIVE AND WELL PRONOUNCED 850/700 MB THETA-E RIDGE AXISES PREVAIL OVER FAR EASTERN WYOMING AND WESTERN NEBRASKA IN THE AFTERNOON WITH SURFACE BASED CAPE VALUES OF 2500-3000 JOULES/KILOGRAM ACROSS WESTERN NEBRASKA AND 1000-2000 J/KG ACROSS EASTERN WYOMING EAST OF INTERSTATE 25. ALTHOUGH CAPE VALUES WILL BE IMPRESSIVE...WARM MID LEVEL TEMPERATURES FROM 16-18C WILL LIKELY PROVIDE ENOUGH CONVECTIVE INHIBITION TO SEVERELY LIMIT CONVECTIVE INITIATION. IN ANY CASE...WILL CONTINUE WITH 10 TO 20 PERCENT THUNDERSTORM CHANCES IN THE AFTERNOON FROM DOUGLAS TO CHEYENNE FOR THE SLIGHT CHANCE OF THUNDERSTORMS ABLE TO OVERCOME THE CONVECTIVE INHIBITION AND WARM LAYER ALOFT. .LONG TERM...TUESDAY NIGHT THROUGH SUNDAY UPPER RIDGE MOVES OFF TO THE EAST TUESDAY EVENING WITH SOUTHWEST WINDS INCREASING ACROSS SOUTHERN WYOMING. THIS DUE TO A CLOSED LOW MOVING INTO NORTHERN NEVADA AND A FAIRLY TIGHT PRESSURE GRADIENT DEVELOPING OVER WESTERN WYOMING. 700MB WINDS INCREASE TO 35 TO 40KTS BY WEDNESDAY MORNING...INCREASING TO 40-45KTS WEDNESDAY AFTERNOON. DEFINITELY A WINDY DAY IN STORE FOR WEDNESDAY...PERSISTING INTO THURSDAY. GFS BRINGS QUITE A SLUG OF MOISTURE INTO THE AREA WEDNESDAY NIGHT/THURSDAY MORNING. ECMWF HOLDS MOISTURE BACK WEST AND IS FORECASTING QUITE A BIT LESS. THIS SEEMS A LOT MORE REALISTIC AND HAVE GONE WITH THE ECMWF SOLUTION. KEPT THE INHERITED SLIGHT CHANCE POPS FOR OUR WESTERN ZONES GOING AND WILL WAIT TO SEE HOW SOLUTIONS SHAKE OUT ON LATER RUNS BEFORE INCREASING POPS ANYMORE. WEDNESDAY LOOKS TO BE OUR WARMEST DAY...WITH 700MB TEMPERATURES +16C OVER SOUTHERN WYOMING...+18C OUT OVER THE PANHANDLE. BOTH THE GFS AND ECMWF SHOW A COOL DOWN FRIDAY WITH 700MB TEMPERATURES DROPPING TO AROUND +8 TO +10C. WARMER TEMPERATURES RETURN FOR THE WEEKEND THOUGH AS UPPER RIDGE BEGINS TO BUILD BACK INTO THE AREA. && .AVIATION...18Z TAFS VFR PRIMARILY WITH TEMPO IFR CONDITIONS IN TSTMS FOR OUR NEBRASKA PANHANDLE TAFS LATER THIS AFTERNOON. DO NOT FORESEE ANY IFR RETURNING TONIGHT IN THE PANHANDLE AS THE COLD FRONT WILL BE THROUGH AND SURFACE WINDS WILL BE DOWNSLOPING OFF THE LARAMIE RANGE. && .FIRE WEATHER... AFTER TODAY...HIGH PRESSURE AND WARMER TEMPERATURES ARE EXPECTED THROUGH MOST OF THE WEEK. DRY CONDITIONS AND GUSTY WEST WINDS WILL PREVAIL DURING THE AFTERNOON WITH MINIMUM HUMIDITIES FALLING INTO THE LOW TO MID TEENS ACROSS WYOMING. THE NEBRASKA PANHANDLE WILL FAIR A LITTLE BETTER WITH RECENT RAINFALL. EXPECT POOR RH RECOVERIES OVERNIGHT WEST OF THE LARAMIE RANGE WITH EXCELLENT RECOVERIES OVER THE PANHANDLE. FUELS ARE STILL GREEN...BUT WILL DRY OUT SIGNIFICANTLY THIS UPCOMING WEEK. && .HYDROLOGY... FLOOD WARNINGS REMAIN IN EFFECT FOR SARATOGA...SINCLAIR...HENRY AND MITCHELL ALONG THE NORTH PLATTE RIVER AS WELL AS THE LARAMIE RIVER NEAR LARAMIE. RIVER LEVELS WILL REMAIN STEADY OR EVEN START TO FALL THIS WEEK ACROSS THE LOWER NORTH PLATTE RIVER. AFTER A BRIEF COOL DOWN MONDAY...VERY WARM TEMPERATURES ARE FORECAST DURING THE WEEK WHICH WILL RESULT IN GREATER MOUNTAIN SNOW MELT. HOWEVER...WITH THE AREAL SNOW PACK IN THE MOUNTAINS IS NOT AS LARGE AS LAST MONTH...DO NOT ANTICIPATE ANY SIGNIFICANT RISES IN AREA RIVERS. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
