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.

EXTREMELY UNSTABLE AIRMASS IN PLACE OVER SCTRL/SE KS INTO NE OK.
MONITORING TO SEE IF ISOLATED CONVECTION CAN TAKE PLACE ALONG

.DISCUSSION...

PREPARING FOR NEXT ROUND OF RAINFALL TONIGHT. MOIST, VERY UNSTABLE
AIRMASS IN PLACE OVER MUCH OF FCST AREA.  INITIAL SHORTWAVE EXITING
THIS AFTERNOON...THINK WEAK SUBSIDENCE IN WAKE OF WAVE MAY INHIBIT
CONVECTIVE DEVELOPMENT THROUGH THE EVENING (EXCEPT FAR SE KS WHERE
NOT YET BEHIND SHORTWAVE AXIS).  WILL HAVE LOW EVENING POPS IN FAR
SE KS FOR THIS EVENING.  MODELS SHOW GOOD SIGNAL FOR CONVECTIVE
SYSTEM TO DEVELOP OVER ERN CO/NW KS THIS EVENING...AND SLIDE ESE
ACROSS CTRL KS LATE TNGT ON NOSE OF LLJ...REACHING SE KS TWRD DAWN.
WILL CONTINUE FLOOD WATCH TONIGHT GIVEN LOW FFG VALUES.  INCREASING
POPS TO LIKELY/CATEGORICAL AFTER MIDNIGHT.  MIGHT SEE A HIGH WIND
THREAT WITH CONVECTION LATE TNGT AS SYSTEM DEVELOPS COLD POOL.

CHANGE IN THE PATTERN TO WEAK SW FLOW BY END OF WEEK WITH RIDGING
BUILDING OVER THE CENTRAL STATES.  SHOULD LEAD TO DRIER WEATHER WITH
HIGH TEMPS RISING BACK ABOVE 90 DEGREE MARK.  EXPECT MCS TRACK TO BE
MORE OVER NEBRASKA FOR NEXT WEEKEND...BUT WE COULD SEE BOUNDARY MOVE
AS FAR SOUTH AS NRN KS...SO HAVE SLIGHT CHANCE POPS FOR OUR CTRL KS
COUNTIES DURING THE NIGHTTIME HOURS.
