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

Springfield, MO (KSGF), launched 12:00Z, 9.4 hours before the alert went out and 118 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.

NATIONAL WEATHER SERVICE TULSA OK
251 PM CDT WED JUN 25 2014

.DISCUSSION...
SCATTERED STRONG PULSE THUNDERSTORMS WILL CONTINUE THROUGH THE
AFTERNOON HOURS BEFORE SLOWLY DISSIPATING THIS EVENING WITH LOSS
OF HEATING. THE STRONGER STORMS WILL LIKELY BE CAPABLE OF
PRODUCING SMALL HAIL/GUSTY WINDS WITH LOCALLY HEAVY RAINFALL
LIKELY.

CONTINUED CHANCE FOR SCATTERED SHOWERS/THUNDERSTORMS MAINLY
DURING PEAK HEATING. ISOLATED STORMS WILL REMAIN POSSIBLE THROUGH THE
WEEKEND AS UPPER LEVEL TROUGH LIFTS INTO THE NORTHERN PLAINS. MAIN
DYNAMICS IN ASSOCIATION WITH SYSTEM WILL STAY NORTH KEEPING OVERALL
PRECIPITATION COVERAGE FAIRLY LIMITED.

UPPER RIDGE WILL SLOWLY BEGIN TO BUILD INTO THE SOUTHERN PLAINS
SUN/MON WITH A SLOW WARMING TREND. WEAK FRONTAL BOUNDARY WILL
APPROACH THE REGION INTO TUESDAY BUT MAY STALL JUST NORTH OF AREA
ACROSS KANSAS/MISSOURI. FOR NOW WILL KEEP JUST SLIGHT CHANCE POPS
ACROSS NE OK/NW AR THROUGH THE REMAINDER OF THE EXTENDED PERIODS.
