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, Mar 31, 2:57 AM CST, 2 hours 57 minutes before
SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 257 AM CST SUN MAR 31 2002 .TODAY... A cold front will advance across the forecast area this morning... with polar air following in the wake of front. Advecting continental air will slide over standing water...causing potential evaporation. I believe that both MOS solutions are too warm. Robust evaporational cooling will partially offset the returning afternoon sun. I will lower the afternoon maximums a few F degrees...more closer to the benchmark normals. .TONIGHT... a polar HIGH builds southeast into the Tennessee Valley. Ongoing cold air advection will keep the nocturnal boundary layer unstable. Radiational-evaporational cooling will allow overnight minimums to fall a few F degrees below the benchmark normals. .MONDAY... A strong April sun will warm afternoon maximums to near 80 degrees... about 5 F degrees above the benchmark normals. Evaporational cooling will be of minor concern...most of the standing waters will have already evaporated. .LCH...NONE .PRELIMINARY NUMBERS...
