What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|
| Apr 18, 12:00 AM CDT | Hail 1 | Jewell, KS |
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.
The nearest sounding before it

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. DROZD
