NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.
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.

Area forecast discussion, Apr 16, 2:30 PM CDT, 5 hours 32 minutes before
SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 230 PM CDT TUE APR 16 2002 MAIN CHALLENGE IS POSSIBLE EVENING WEATHER...THEN TEMPERATURES. LATEST SURFACE ANALYIS SHOWS DRIER AIR INVADING THE AREA...WITH DEW POINTS ONLY HOLDING ON IN THE FAR EAST CWFA. NEGATIVELY TILTED UPPER SHORT WAVE SWINGING OUT OF SOUTHERN HIGH PLAINS WILL PROVIDE PLENTY OF LIFT THIS EVENING...BUT WITH ONLY LIMITED MOISTURE TO WORK WITH...THREAT OF THUNDERSTORMS...LET ALONE SEVERE WEATHER...NOW QUITE SLIM IN GID CWFA. BIGGEST THREAT WOULD BE WIND FROM A HIGH BASED STORM IN THE NORTHEAST CWFA. WILL KEEP A SMALL POP FOR THE EAST...NEAR THE 850 MB DEW POINT BOUNDARY...BUT REMOVE ELSEWHERE. IN THE MEAN TIME...WINDS BEGINNING TO DIMINISH AS BOUNDARIES CROSS THE AREA AND WILL LIKELY CANCEL THE WIND ADVISORY BY AFTN ZFP ISSUANCE. AS WINDS SHIFT TO THE NORTHWEST AND DIMINISH...TEMPS WILL DROP TONIGHT...UNLIKE THE PAST FEW NIGHTS. GUIDANCE GENERALLY ACCEPTED. QUICK RETURN FLOW SETS UP WEDNESDAY AND TEMPS SHOULD RECOVER NICELY...MAYBE EVEN A BIT ABOVE GUIDANCE. BUT STORMS NOT LIKELY TO GET GOING UNTIL NIGHTTIME IN AN AREA OF LOW LEVEL THETA E ADVECTION...WHICH WILL PLACE THE FOCUS NORTHEAST OF OUR AREA...SO WILL LEAVE DRY. NO BIG CHANGES TO THE EXTENDED PACKAGE. COOLER AIR WORKS INTO THE AREA THU NGT...BUT MOISTURE APPEARS TOO LIMITED TO PRODUCE ANY PCPN EXCEPT MAYBE IN THE SOUTH. MADE ONLY SLIGHT DOWNWARD ADJUSTMENTS TO TEMPS FOR THE END OF THE WEEK AS UPPER TROUGH MOVES IN. BEST CHANCE FOR RAIN LOOKS LIKE SUNDAY. .GID...NONE. DROZD
