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 NATIONAL WEATHER SERVICE JACKSON MS 235 PM CDT MON JUN 24 2002 FORECAST ISSUES TODAY ABOUT SAME AS PAST SEVERAL DAYS. FORECAST REVOLVES AROUND PROGRESS OF UPPER-LEVEL LOW PRESSURE SYSTEM ACROSS LA/CLOUD COVER/AMOUNT OF RAIN WITH SYSTEM. ANOTHER PROBLEM TODAY/TUE IS POTENTIAL FOR ISOLATED SEVERE STORMS.

BETTER INSOLATION/TEMPS WARMER THAN SUN ALLOWED AIRMASS TO DESTABILIZE MORE RAPIDLY. LIS ALREADY -6 TO -8 OVER AREA.

IN ALL...EXPECT BETTER THUNDERSTORM DEVELOPMENT THIS AFTERNOON/EVENING...WITH AN ISOLATED SEVERE STORM POSSIBLE WILL NOT MENTION SEVERE IN ZONES. GIVEN DEEP MOISTURE...AN EFFICIENT STORM COULD PRODUCE BRIEF HEAVY RAINFALL. MODEL SCENARIOS STILL CONVERGE ON SOLUTION OF UPPER LOW SHIFTING INTO NW LA TONIGHT. UPPER LOW THEN MOVES WEST INTO ARLATX BY 12Z TUE. EARLIER MODEL RUNS TOOK UPPER LOW NORTH INTO SW AR. SEVERAL WEAK SHORTWAVES WILL RIPPLE THROUGH RELATIVELY WEAK MID-/UPPER-LEVEL FLOW. IN PROGS...DEWPOINTS/PRECIP WATER VALUES/LOWER-LEVEL RELATIVE HUMIDITIES ALL REMAIN HIGH. YET...AVN/ETA BOTH ENTRAIN SIGNIFICANTLY DRIER AIR OVER CWFA FROM EAST AT MID-/UPPER-LEVELS BY 12Z TUE. FROM 12Z TUE ON...MODELS BEGIN TO DIFFER. ETA DEVELOPS SURFACE HIGH PRESSURE AREA OVER NRN GULF MX. ETA ALSO OPENS CLOSED LOW PRESSURE CENTER BY 06Z WED OVER ARLATX. COMBINATION OF THESE DEVELOPMENTS APPEAR TO DIMINISH SUPPORT FOR PRECIP OVER CWFA TUE/WED IN ETA. PRESENCE OF DRIER AIR COULD MEAN LESS CLOUDINESS (MAINLY ERN ZONES). OVERALL..PREFER AVN SOLUTION WHERE LOW PRESSURE SYSTEM REMAINS CLOSED OVER ARLATX THROUGH 18Z WED/MAIN TROUGH AXIS PERSISTS JUST WEST OF CWFA. GIVEN DIURNAL HEATING OF BASICALLY TROPICAL AIRMASS/ANY MESO-SCALE BOUNDARIES THAT MIGHT DEVELOP/WEAK SHORTWAVES RIPPLING OVER CWFA... EXPECT SCATTERED CONVECTION OVER THROUGH WED. WITH MORE INSOLATION/ MORE INSTABILITY/STEEPER TEMP LAPSE RATES...COULD MAKE ARGUMENT FOR ISOLATED SEVERE STORMS TUE...ESPECIALLY ERN ZONES. FROM WED THROUGH NEXT MON...AVN/MRF/NOGAPS SOLUTIONS KEEP WEAKENED UPPER LOW PRESSURE REMNANTS AROUND ARLATX...WITH ABUNDANT MOISTURE OVER LOWER MS RIVER VALLEY. UPPER-LEVEL/SURFACE HIGH PRESSURE DEVELOPS OVER WRN STATES...THOUGH IMPACTS WILL NOT BE FELT OVER CWFA. BY 12Z SAT...SOME SLIGHTLY DRIER AIR PUSHES INTO REGION FROM EAST IN CIRCULATION AROUND DEVELOPING HIGH PRESSURE AREA OVER GA/FL. HOWEVER...NO MAJOR WEATHER SYSTEM APPROACHES CWFA TO SCOUR AIRMASS OF MOISTURE. GIVEN PERSISTENT SOGGY AIRMASS..EXPECT PARTLY CLOUDY SKIES WITH SOME DIURNAL CONVECTION EACH DAY. LOCALLY HEAVY RAINFALL COULD DEVELOP THROUGH EXTENDED. WILL TREND TOWARDS AVN GUID VALUES. DAYTIME TEMPS GENERALLY IN 80S. OVERNIGHT LOW GENERALLY IN 60S TO LOWER 70S.

SEVERE STORMS ARE NOT EXPECTED...HOWEVER...A FEW STORMS MAY PRODUCE WIND GUSTS TO 45 MPH AND SMALL HAIL MAINLY WEST OF THE MISSISSIPPI RIVER. AN UPPER LEVEL LOW PRESSURE SYSTEM WILL CONTINUE TO REMAIN NEARLY STATIONARY TONIGHT OVER CENTRAL PORTIONS OF LOUISIANA. MOIST SOUTHERLY FLOW AND DAYTIME HEATING WILL COMBINE WITH THE UPPER LEVEL SYSTEM TO CONTINUE PRODUCING SHOWERS AND THUNDERSTORMS OVER MUCH OF THE AREA THIS AFTERNOON AND EVENING. ACTIVITY SHOULD BEGIN DECREASING AFTER SUNSET...BUT A FEW STORMS COULD LINGER OVERNIGHT AS THE UPPER LOW CONTINUES TO PROVIDE UPPER LEVEL INSTABILITY TO SUSTAIN SOME SHOWER AND THUNDERSTORM DEVELOPMENT.
