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.

SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
313 PM CDT WED APR 17 2002

THUNDERSTORM CHANCES AND TEMPERATURES MAIN CHALLENGES.

LATEST SURFACE ANALYSIS SHOWS WARM FRONT NEAR THE NEBR/KANSAS
BORDER. A DRY LINE EXTENDS ACROSS WESTERN KS CWFA COUNTIES.  LOW
LEVEL MOISTURE WILL ADVECT ACROSS EASTERN CWFA THIS EVENING BEFORE
DRIER AIR PUNCHES THROUGH.  WATER VAPOR IMAGERY SHOWS A JET MAX
ADVANCING NE OUT OF NEW MEXICO WHICH LOOKS TO HAVE SOME MID LEVEL
MOISTURE ASSOCIATED WITH IT.  WITH GOOD HEATING TODAY AFTER A CHILLY
START...ENOUGH INSTABILITY TO PROVIDE ALL INGREDIENTS FOR
THUNDERSTORM DEVELOPMENT THIS EVENING ALONG THE FRONT. BIGGEST
PROBLEM WILL BE OVERALL COLUMN MOISTURE WHICH WILL SUPPORT ONLY
ISOLATED TO SCATTERED COVERAGE AT BEST.  WILL PUT IN SMALL POPS
ACROSS THE EAST BUT BEST CHANCES WILL BE LATER TONIGHT FARTHER
NORTHEAST...OUT OF CWFA...WHEN/WHERE LOW LEVEL JET/THETA E ADVECTION
REALLY FOCUSES MOISTURE.  ETA 310 K ISENTROPIC SURFACE IS QUITE IS
STEEP LATER TONIGHT TO THE NORTHEAST.

THOSE SOUTH WINDS WILL INCREASE TONIGHT DUE TO DEEPENING SURFACE LOW
OVER THE DAKOTAS.  EXPECT WINDY CONDITIONS OVERNIGHT WHICH WILL KEEP
TEMPERATURES AOA GUIDANCE...QUITE A BIT ABOVE GOING FORECAST.  AS
MENTIONED IN NATL DISCN...FRONTAL MOVEMENT THU HAS TRENDED SLOWER
AND THERE MAY BE ENOUGH RESIDUAL MOISTURE ALONG WITH DAYTIME HEATING
TO KICK OFF A TSTM THU EVENING IN THE SOUTHERN CWFA...SO HAVE KEPT
SMALL POPS THERE.

COOL HIGH PRESSURE THEN BUILDS IN FOR THE WEEKEND...BUT NOT BEFORE
MORE WIND THU NGT.  HAVE DELAYED RAIN CHANCES HOWEVER...UNTIL EARLY
NEXT WEEK WHEN OVER RUNNING OF THE HIGH BEGINS WITH NEXT RESURGENCE
OF A WARMER AIRMASS.

.GID...NONE.
