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
300 PM CDT SUN MAY 26 2002

ZONE BREAKUP WILL BE LARGELY DEPENDENT UPON ONGOING CONVECTION AT
TIME OF ZONE ISSUANCE. MAIN FORECAST PROBLEM WILL BE THE FIRST
PERIOD POPS. THE SECOND PROBLEM CONTINUES TO BE THE CHANCES OF
PRECIP IN THE EXTENDED...WHICH WILL DEPEND HEAVILY ON WHAT HAPPENS
ALONG THE SOUTHEAST COAST.

OLD FRONTAL BOUNDARY STILL SITUATED JUST TO THE NORTH OF THE CWFA.
THIS FRONT HAS NOT MOVED VERY MUCH SOUTHWARD DURING THE DAY
TODAY...AND DONT EXPECT TOO MUCH MORE SOUTHWARD MOVEMENT. BOTH THE
AVN AND ETA MOVE THIS BOUNDARY SOUTH OF THE INTERSTATE 20
CORRIDOR...BUT NOT TOO CONFIDENT THAT SCENARIO WILL PAN OUT. OLD
BOUNDARY MAY FLIRT WITH THE NORTHERN TIER OF ZONES AS IT WAVES BACK
AND FORTH OVER NORTHERN PORTIONS OF MISSISSIPPI THROUGH TUESDAY.
OTHERWISE...CONVECTION SHOULD REMAIN MORE DIURNAL IN NATURE...AND
SHOULD MAINLY BE FUELED BY HEATING...HARD TO TIME AND TRACK
SHORTWAVES MOVING EAST IN THE UPPER FLOW...AND OLD OUTFLOW
BOUNDARIES. CURRENT FORECAST SEEMS TO HAVE THIS TREND HANDLED VERY
WELL...AND WILL ONLY MAKE MINOR CHANGES IN THE SHORT TERM PERIOD OF
THE FORECAST.

NOT TOO CONFIDENT IN THE EXTENDED PORTION OF THE FORECAST. THE
MODELS ARE CONTINUING TO INDICATE A SUBTROPICAL LOW AFFECTING THE
EAST COASTS OF FLORIDA...GEORGIA AND SOUTH CAROLINA. JUST AS
PROBLEMATIC IS THE DIGGING UPPER LEVEL TROUGH AND ASSOCIATED LOW
SAGGING SOUTHWARD OVER EASTERN TEXAS AND FINALLY INTO THE EXTREME
WESTERN GULF OF MEXICO. ANOTHER FRONTAL BOUNDARY IS ALSO EXPECTED TO
APPROACH THE MISSISSIPPI RIVER BY LATE THURSDAY/FRIDAY AND GET
CAUGHT BETWEEN THE TWO SYSTEMS. THE CHANCES OF PRECIP WILL VARY
GREATLY UPON WHAT ACTUALLY HAPPENS WITH THESE SYSTEMS. WITH THIS
SAID...WILL KEEP ONGOING CHANCES OF PRECIP THROUGH SATURDAY AND SEE
HOW LATER RUNS OF THE MODELS HANDLE THE SITUATION.

FOR TONIGHT...12Z UPPER AIR ANALYSIS INDICATED A SHORTWAVE OVER
CENTRAL LOUISIANA AND ARKANSAS. THIS FEATURE WAS NOT VERY WELL INITIALIZED BY
THE ETA...BUT WAS HANDLED SLIGHTLY BETTER BY THE AVN. THIS FEATURE
WILL SERVE TO ENHANCE THE ONGOING CONVECTION THIS AFTERNOON AND INTO
THE EVENING HOURS. OUTFLOW BOUNDARIES WILL ALSO LEND A HAND TO THE
DEVELOPMENT AND SUSTAINMENT OF STORMS. CONVECTION IN THE SOUTHEAST
AND EAST CENTRAL ZONES SHOULD BE LIMITED AGAIN TODAY. OBSERVATIONS
ARE INDICATING SOMEWHAT DRIER AIR OVER THAT REGION AND STORMS ARE
HAVING A HARD TIME MAKING IT SOUTH OF THE NATCHEZ TRACE. POPS
TONIGHT WILL BE GREATEST ALONG AND NORTH OF THE NATCHEZ TRACE
PARKWAY.
