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
Nashville Metro, TN (KBNA), launched 12:00Z, 8.0 hours before the alert went out and 93 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 NASHVILLE TN 221 PM CDT MON MAY 25 2015 .DISCUSSION...A PERSISTENT BAND OF SHOWERS CONTINUES TO MOVE SLOWLY EASTWARD ACROSS MIDDLE TENNESSEE, WITH A FEW STRONGER CELLS PASSING THROUGH SOUTHERN PARTS. HRRR HAS PERFORMED QUITE WELL TODAY, AND THE SHORT-RANGE MODEL HAS CONSISTENTLY SHOWN A DECREASE IN THE ACTIVITY FROM LATE AFTERNOON THROUGH EVENING, SO AM SPLITTING TONIGHT'S POP GRID INTO 6-HOUR INCREMENTS, WITH REDUCED POP'S FROM 00Z THROUGH 06Z. NAM SHOWS A WEAK TROUGH MOVING INTO MIDDLE TENNESSEE TOMORROW MORNING ALONG WITH THE NEXT WAVE OF MOISTURE, THEREBY PUSHING THE DRY WEDGE NORTHWARD AND BRINGING LIKELY TO CATEGORICAL POP'S BACK IN. SPC IS KEEPING THE ENTIRE MID STATE UNDER A SLIGHT RISK OF SEVERE STORMS TOMORROW AND TOMORROW NIGHT, AND A MARGINAL RISK FOR DAY 3. MODEL SOUNDINGS CONTINUE TO SHOW GOOD INSTABILITY FOR THE NEXT SEVERAL DAYS, MAINLY DURING PEAK HEATING HOURS, WITH VERY LITTLE AIR MASS CHANGE FOR THE FORESEEABLE FUTURE.
