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 19, 1:40 PM CDT, 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
140 PM CDT FRI APR 19 2002

MAIN CONCERN FOR THIS FORECAST CONTINUES TO BE CONVECTION THROUGH
SUNDAY EVENING...AND THEN THE DEGREE OF COOLING FOR MONDAY.

LARGE AREA OF SHOWERS AND SOME STRONG THUNDERSTORMS OVER THE
EVANSVILLE TRI STATE AREA SEEMS TO BE TIED TO GOOD WARM ADVECTION
PATTERN.  MEANWHILE...MORE ISOLATED LARGE STRONG/SEVERE STORMS WERE
APPROACHING SOUTHEAST MISSOURI.  EXPECT THE CLUSTER TO THE NORTHEAST
TO MOVE OUT OF THE AREA BY ISSUANCE TIME...WITH POSSIBLY SOME
LINGERING RAINS IN THE FAR EAST.  HOWEVER...THE STORMS OVER
SOUTHEAST MISSOURI ARE LIKELY TO BE A FLY IN THE OINTMENT INTO THE
EVENING ACROSS SOUTHERN ILLINOIS OR WESTERN KENTUCKY.

OTHERWISE TONIGHT...MOST OF THE AREA SHOULD BE DRY INTO THE EARLY
MORNING HOURS...WHEN THE FRONT FINALLY MOVES INTO THE AREA WITH
SHOWERS AND THUNDERSTORMS ALONG AND BEHIND IT.  WILL GO WITH
OCCASIONAL WORDING AFTER MIDNIGHT IN THE NORTH...WHILE SOUTHERN
ZONES WILL BE DEPENDENT ON THE TRENDS THIS AFTERNOON.  THE MESOETA
AND AVN ARE IN AGREEMENT IN PUSHING THE FRONT THROUGH THE ENTIRE
AREA BY AROUND 18Z SATURDAY...SO WILL POST LIKELY POPS THROUGHOUT
THE AREA FOR SATURDAY.

FOR SATURDAY NIGHT THE FRONT WILL BECOME STATIONARY AND MAY BEGIN TO
MOVE BACK TO THE NORTH LATE.  WILL SEE LIKELY POPS AGAIN...PRIMARILY
LATE...ACROSS THE NORTHERN ZONES...WITH CHANCE POPS SOUTH.  WILL
KEEP SIMILAR POP ARRANGEMENT FOR SUNDAY...AS THE WARM FRONT WILL BE
ALONG THE NORTHERN EDGE OF THE AREA AND THE COLD FRONT APPROACHES
SOUTHEAST MISSOURI BY LATE AFTERNOON.  LATE SUNDAY AFTERNOON AND
EARLY EVENING WILL LIKELY BE OUR BEST CHANCE FOR WIDESPREAD
ORGANIZED SEVERE WEATHER AS THE COLD FRONT SWEEPS ACROSS THE AREA.

WILL MENTION HEAVY RAINFALL FOR TONIGHT AND SATURDAY WITH LIKELY OR
BETTER POPS.  COULD CONTINUE TO SEE HEAVY RAIN THROUGH SUNDAY
EVENING...BUT WILL NOT MENTION IT BEYOND THE FIRST TWO PERIODS.  A
FLOOD WATCH MAY BE NECESSARY...BUT AM NOT CONFIDENT ENOUGH IN THE
EVOLUTION OF THE PRECIPITATION TO ISSUE IT AT THIS TIME.

THE EXTENDED PERIODS WILL NOT BE DRASTICALLY DIFFERENT FROM CURRENT
FORECAST...BUT MAY SEE SOME WRAPAROUND CLOUDS AND COOLER
TEMPERATURES ACROSS THE EVV AREA ON MONDAY...AS AN UPPER TROUGH DIGS
FURTHER SOUTH TO OUR EAST THAN PREVIOUSLY EXPECTED.  RAPID WARM UP
IS IN STORE FOR TUESDAY WITH ANOTHER SHOT AT CONVECTION FOR
WEDNESDAY.  THE END OF THE WEEK LOOKS MILD AND DRY.

GENERALLY WENT NEAR THE WARMER MAV GUIDANCE THROUGHOUT THE
FORECAST...AND EVEN WENT A BIT ABOVE IT FOR SUNDAYS HIGHS.

.PAH...NONE.
