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.

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 309 PM CDT WED MAY 29 2013

FOCUS ON EVOLUTION OF SEVERE STORMS TONIGHT AND FLOODING THREAT.

STRONG SHORT WAVE TROUGH NOW MOVING INTO THE PLAINS HELPING TO
DEEPEN THE SFC LOW ACROSS WESTERN KS. GUSTY SOUTH WINDS WILL PERSIST
AS A 60KT LLJ DEVELOPS AFTER 00Z. LARGE CLUSTER OF SEVERE STORMS
ALREADY DEVELOPING WILL CONGEAL INTO A LINE AND MOVE INTO THE CWA
AFTER 00Z. ADDITIONAL STORMS MAY DEVELOP WITHIN ZONE OF ASCENT/WAA
NEAR THE NEBRASKA BORDER LATE THIS AFTERNOON. WILL HAVE TO WATCH
BOTH SCENARIOS SINCE LL SHEAR WILL BE INCREASING AOA 20KTS MOST
AREAS THIS EVENING/TONIGHT AND 6KM SHEAR OF 40KTS WILL BE COMMON
ACROSS MUCH OF THE CWA. EXPECT SUPERCELL STRUCTURES EMBEDDED WITHIN
LINES TONIGHT. ALL HAZARDS INCLUDING LARGE HAIL...DAMAGING WINDS AND
TORNADOES WILL AGAIN BE POSSIBLE. ALSO CONCERNED ABOUT THE POTENTIAL
FOR ANOTHER PROLONGED PERIOD OF HEAVY RAINS IF A COMPLEX DEVELOPS
AND MOVES SOUTHEAST ACROSS THE AREA SO HAVE ISSUED A FLASH FLOOD
WATCH FOR NORTHERN THIRD ANTICIPATING MORE HEAVY RAINS WILL CAUSE
FLOODING IN AREAS ALREADY SATURATED.

ON THURS...MID LEVEL TROUGH AXIS WILL SWEEP THROUGH PERHAPS ALLOWING
A BRIEF BREAK IN THE SEVERE WEATHER THROUGH MID AFTERNOON. MORNING
CONVECTION IS EXPECTED TO LINGER BUT BY LATER AFTERNOON IT APPEARS
THAT ANOTHER SFC BOUNDARY COULD END UP IN THE CWA SOMEWHERE AND BE
THE FOCUS FOR ADDITIONAL SEVERE STORMS BY LATE DAY. UPPER JET WILL
INCREASE SO DEEP SHEAR WILL BE STRONGER THU IT APPEARS ANOTHER RISK
FOR TORNADOES...HAIL...DAMAGING WINDS EXISTS FOR OUR AREA THURS PM.
WISH THERE WAS BETTER NEWS BUT THAT IS THE WAY IT LOOKS AT THIS
POINT.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 309 PM CDT WED MAY 29 2013

SHORT RANGE MODELS CONSISTENT IN HANGING UP DRYLINE ACROSS CENTRAL
KANSAS THURSDAY NIGHT...AND AFTERNOON AND EVENING CONVECTION FORMING
INTO A POTENTIALLY SEVERE MCS THAT TRAVERSES EASTERN KS OVERNIGHT.
ALONG WITH SEVERE WEATHER...MORE HEAVY RAIN WILL BE POSSIBLE AND
ANOTHER FLASH FLOOD WATCH COULD BE NEEDED OVERNIGHT.  ON
FRIDAY...REMNANT OF SAID MCS COULD BE EXITING NORTHEAST KS DURING
THE MORNING...AND THEN COMBINATION OF OUTFLOW BOUNDARY WITH FRONT
SETS UP OVER OVER EC KS FOR THE AFTERNOON.  BEST CHANCE OF AFTERNOON
CONVECTION WOULD BE ALONG AND SOUTHEAST OF THE KANSAS
TURNPIKE...WITH SEVERE WEATHER STILL POSSIBLE IN THAT AREA ON
FRIDAY.

PRECIP ALONG/AHEAD OF FRONTAL BAND EXPECTED TO EXIT EC KS FRIDAY
EVENING AND THEN CONTINUE PUSHING AWAY FROM THE AREA ON SATURDAY
WITH A REINFORCING COLD FRONT SWEEPING THROUGH.  THEN DRY CONDITIONS
SHOULD PREVAIL THROUGH THE WEEKEND INTO MONDAY AS A SURFACE HIGH
PRESSURE RIDGE SLIDES EAST ACROSS THE AREA.

NEXT CHANCE OF CONVECTION WOULD APPEAR TO BE MONDAY NIGHT IN WARM
ADVECTION AHEAD OF A WEAK MID-LEVEL TROUGH IN NEARLY ZONAL FLOW
ALOFT.  THIS FLOW RESULTS IN AN INVERTED SURFACE TROUGH ACROSS KS...
AND THIS INTERACTING WITH WEAK UPPER-LEVEL WAVES...WILL PRODUCE
OFF AND ON CHANCES FOR SHOWERS AND THUNDERSTORMS FROM MONDAY NIGHT
THROUGH WEDNESDAY.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 709 PM CDT WED MAY 29 2013

PREVAILING CIGS WILL LOWER TO MVFR THIS EVENING AND PERSIST
