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
Amarillo Airport, TX (KAMA), launched 00:00Z, 3.7 hours before the alert went out and 31 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 AMARILLO TX 714 PM CDT FRI JUN 22 2007 .AVIATION... CONVECTION INITIATION EVIDENT ON RADAR MAINLY ACROSS EASTERN NEW MEXICO...WITH ISOLATED STORMS BUILDING ACROSS THE WESTERN PANHANDLES. FELT TEMPO GROUPS FOR PRECIP WILL BE BEST BET AS THE STORMS ARE ISOLATED AND VERY SLOW MOVING. THINKING KDHT WILL STILL HAVE THE FIRST AND BEST CHANCE FOR THUNDER...THEN COULD SEE PRECIP SPREAD EAST THROUGH THE EARLY EVENING. WITH MID TO HIGH CLOUDS IN PLACE OVERNIGHT...NOT EXPECTING LOW CLOUDS OR BR TOMORROW MORNING. THEN CONVECTION MAY INITIATE AGAIN TOMORROW AFTERNOON...BUT NOT CONFIDENT TO PUT PRECIP IN TAFS. WINDS WILL GENERALLY REMAIN OUT OF THE SOUTH TO SOUTHEAST. JJB && .PREV DISCUSSION... /ISSUED 226 PM CDT FRI JUN 22 2007/ DISCUSSION... MOIST AIRMASS WILL REMAIN ENSCONCED OVER THE PANHANDLES NEXT SEVERAL DAYS. UPPER TROF WILL MOVE IN THIS EVENING...WITH SCT TSRA DEVELOPING ON THE HIGHER TERRAIN TO THE NORTHWEST. STEERING FLOW IS SUFFICIENTLY WESTERLY THAT STORMS SHOULD BE ABLE TO MOVE INTO AT LEAST THE NORTHWESTERN ZONES...BUT WITH THERMODYNAMICS FAVORABLE FOR THUNDERSTORMS OVER MUCH OF THE CWA...STORMS MAY PERSIST FURTHER EAST. THEREFORE INCREASED POPS FOR THE WESTERN ZONES TONIGHT...AND CONTINUED SLIGHT CHANCE POPS EASTERN ZONES. UPPER TROF REMAINS IN VCTY NEXT SEVERAL DAYS...AND ENGAGES IN BATTLE WITH UPPER RIDGE FOR DOMINANCE. STEERING FLOW BECOMES SLIGHTLY MORE NORTHERLY SATURDAY EVENING...BUT ATMOSPHERE REMAINS PRIMED FOR THUNDERSTORMS AGAIN. TSRA SHOULD ONCE AGAIN DEVELOP ON THE HIGHER TERRAIN...BUT WILL LIKELY NOT MAKE AS MUCH PROGRESS INTO THE PANHANDLES. THEREFORE INTRODUCED SLIGHT CHANCE POPS NORTHWESTERN ZONES ONLY SAT NIGHT. THEREAFTER...TIMING/LOCATION OF SHEAR ZONE BETWEEN UPPER TROF AND UPPER RIDGE WILL DICTATE POPS FOR THE PANHANDLES. WILL NOT INCLUDE MENTIONABLE POPS FOR THE REMAINDER OF FORECAST PERIODS UNTIL THE POSITION OF THE RIDGE AND TROF CAN BE BETTER TEMPORALLY AND SPATIALLY DEFINED BY THE MODELS. AT THIS TIME...IT DOES APPEAR THAT BEST CHANCES OF PRECIPITATION FROM THIS SYSTEM WILL BE TUESDAY AND WEDNESDAY...AND HAVE RAISED POPS TO JUST BELOW SLIGHT CHANCE THESE PERIODS. TSRA COULD BE POSSIBLE DAILY...BUT DOES NOT SEEM PRUDENT TO BROADBRUSH WHEN SUCH STORMS WILL BE HIT OR MISS. MIN TEMPERATURES ON THE WHOLE FOLLOWED MEXMOS...AND WILL REMAIN GENLY IN THE 60S AS MOISTURE CONTENT OF THE ATMOSPHERE REMAINS HIGH. MAX TEMPS VARIED THROUGHOUT THE FORECAST PACKAGE. IN THE SHORT TERM...LINGERING MOISTURE...MORNING CLOUD COVER AND LESSER IMPACT FROM UPPER RIDGE DICTATED UNDERCUTTING MEXMOS IN THE EASTERN ZONES TODAY AND TOMORROW. TUES AND WEDS WINDS ACQUIRE AN UPSLOPE COMPONENT...AND CLOUD COVER IS EXPECTED TO INCREASE...AND HAVE COOLED TEMPS BELOW MEXMOS AS A RESULT.
