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.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE HASTINGS NE
321 PM CDT SUN JUN 2 2002

...SPOTTER ACTIVATION IS NOT ANTICIPATED TONIGHT ACROSS SOUTH CENTRAL
NEBRASKA OR NORTH CENTRAL KANSAS...

DAYTIME HEATING HAS ALLOWED THE AREA TO BECOME QUITE UNSTABLE THIS
AFTERNOON. IN THE MEANTIME...SOUTHERLY FLOW HAS FORCED ADDITIONAL LOW
LEVEL MOISTURE INTO THE PLAINS...HELPING TO FURTHER DESTABILIZE THE
ATMOSPHERE. AS SURFACE LOW PRESSURE MOVES ACROSS SOUTHERN NEBRASKA...
WIDELY SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO FORM THIS
EVENING. A FEW STORMS MAY BE ACCOMPANIED BY GUSTY WINDS.

THUNDERSTORMS THAT DO DEVELOP THOUGH...ARE NOT EXPECTED TO BECOME
VERY ORGANIZED AS WARM MID LEVEL TEMPERATURES HELP TO INHIBIT
THUNDERSTORM GROWTH...THUS SPOTTER ACTIVATION IS NOT ANTICIPATED.

THE BEST CHANCE FOR THUNDERSTORM ACTIVITY APPEARS TO BE MAINLY FOR
AREAS NORTH OF I-80 THIS EVENING...WHILE ISOLATED ACTIVITY IS
EXPECTED IN NORTH CENTRAL KANSAS.
