What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|
| May 1, 9:15 PM EDT | Hail 0.88 | Manchester, KY |
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, May 1, 2:55 PM EDT, 5 hours 52 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 255 PM EDT WED MAY 01 2002 LOT OF THINGS TO THINK ABOUT. CHALLENGES CENTER AROUND POPS AND SVR/HVY RAIN THREAT. AT THIS TIME...IT APPEARS THAT THE BOUNDARY THAT HAD MADE IT DOWN INTO THE CWA FROM THE N LAST NIGHT HAS MOVED UP ALONG THE OH RIVER. THE WARM FRONT THAT WAS TO OUR S THIS MORNING HAS SURGED N AND IS NOW LOCATED FROM THE CONFLUENCE OF THE OH AND MS RIVERS TO JUST N OF LOZ AND OVER INTO SE NC. CONVECTION IS BEGINNING TO FIRE JUST N OF THE FRONT NEAR NOSE OF 850 JET. MORE CONVECTION SHOULD CONTINUE TO FIRE ALONG AND N OF THIS BOUNDARY TONIGHT WITH GOOD ISENTROPIC LIFT OVER THE BOUNDARY ON STRENGTHENING LLJ. IT APPEARS THAT THE NORTHERN PART OF THE CWA WOULD HAVE THE GREATEST THREAT OF HVY RAIN AND SEVERE WEATHER FOR MOST OF THE NIGHT DEPENDING ON HOW FAR NORTH THE WARM FRONT EVENTUALLY GETS. THEY WILL BE CLOSEST TO SFC LOW TRACK AND UPPER LEVEL DYNAMICS WILL BE BEST THERE. THERE ALSO APPEARS TO BE SOME THREAT TOMORROW OF SVR WX AND LOCALLY HVY RAIN UNTIL THE FRONT CROSSES THE REGION. THE SFC COLD FRONT WILL GRADUALLY CROSS THE REGION DURING THE DAY. WILL ALSO MENTION RAIN HEAVY BOTH LATER TONIGHT AND ON THURSDAY AS PWS PEAK NEAR 1.5. STORMS WILL BE RATHER PROGRESSIVE AND FLOOD THREAT SHOULD BE MORE LOCALIZED. FEEL THAT THE LOW WILL DEEPEN A LITTLE MORE AS SHORTWAVE DROPS DOWN FROM THE NORTHERN PLAINS. THE PRESENCE OF THIS SHORTWAVE WILL ENHANCE DIVERGENCE OVER THE REGION...ESPECIALLY TO OUR N...GIVING AN ENHANCED HVY RAIN THREAT ALONG AND N OF THE OH RIVER. WITH THE FAIRLY STRONG LOW...TIGHT PRESSURE GRADIENT WILL BE ACROSS THE REGION AND WILL MENTION BREEZY LATER TONIGHT AND TOMORROW. THE AVN SPEED SEEMED A BIT FAST AND HAVE NOT BOUGHT INTO IT. SOMETHING MORE IN LINE WITH THE 12Z ETA LOOKS TO BE CLOSER TO REALITY. HAVE KEPT IN CHANCE OF SHOWERS ON SAT AND ADDED SLIGHT CHANCE TO THE N. WILL ALSO INTRODUCE CHANCE S AND SLIGHT CHANCE LATE FRI NIGHT. AS FRONT STALLS TO OUR S...PM MCS DEVELOPMENT TO OUR SW APPEARS REASONABLE WITH IT TRAVERSING INTO TN AND SKIRTING OUR SOUTHERN COUNTIES. EXTENDED...RIDGE BUILDS OVER THE EASTERN UNITED STATES...WITH HIGH HEIGHTS AND 8H TEMPS IN THE +14 TO 16 C RANGE...HAVE GONE ABOVE MEX NUMBERS FOR TUE AND WED. FRONT DROPPING DOWN FROM THE N WILL BRING AN ENHANCED PRECIP CHANCE ON MON. WITH SEVERAL HARD TO TIME DISTURBANCES ROTATING AROUND THE UPPER LEVEL RIDGE...AFTERNOON OR EVENING SHOWERS AND THUNDERSTORMS ARE POSSIBLE EACH DAY PARTICULARLY FARTHER AWAY FROM THE CENTER OF THE RIDGE NEAR THE OH VALLEY. WORK ZONES WILL BE OUT AS SDFOZFJKL BEFORE TOO LONG. .JKL...SPS FOR ALL ZONES FOR THREAT OF SVR WX AND HVY RAIN. PELTON
