The radar

The Columbus AFB radar (KGWX), 89 km from the middle of the area, began a volume at 17:18 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

The nearest sounding before it

Little Rock, AR (KLZK), launched 12:00Z, 5.3 hours before the alert went out and 150 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Apr 1, 10:05 AM CST, 1 hour 12 minutes before

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE JACKSON MS
1005 AM CST FRI APR 1 2005

.DISCUSSION...
JUST DID A QUICK UPDATE TO THE FORECAST WITH NEW ZONES OUT AND
REVISED ZONES BEING SENT. AN AREA OF LOW PRESSURE HAS FINALLY
DEVELOPED ACROSS THE LOWER MISSISSIPPI VALLEY THIS MORNING IN
RESPONSE TO THE UPPER LOW MOVING IN FROM THE WEST. WINDS HAVE TURNED
AROUND WEST/NORTHWEST WEST OF INTERSTATE 55 WHERE LOW LEVEL COLD
ADVECTION IS UNDERWAY...DRIVING LOW CLOUD...LIGHT RAIN AND DRIZZLE
FORMATION. FURTHER EAST...HOLES IN CLOUD COVER IN THE WARM SECTOR
HAVE ALLOWED TEMPERATURES TO SPIKE UP TO AROUND 70 IN MANY LOCATIONS
AND SOME SURFACE-BASED INSTABILITY IS PRESENT. AT LEAST ISOLATED
THUNDERSTORMS SHOULD FORM LATE THIS MORNING INTO THE MIDDAY HOURS AS
THE SURFACE LOW AND COLD FRONT SHIFT EAST AND UPPER FORCING PROVIDES
SOME LIFT ALOFT. DEEP MOISTURE IS SOMEWHAT LACKING SO SEVERE STORMS
ARE NOT EXPECTED AND ADDITIONAL HEAVY RAINFALL IS NOT ANTICIPATED AT
THIS TIME. OTHER RUMBLES OF THUNDERSTORMS...ELEVATED IN
NATURE...WILL BE POSSIBLE OVER THE NORTHERN EDGE OF THE CWA...EVEN
BACK WEST INTO THE DELTA. NOTHING SIGNIFICANT IS EXPECTED HERE
EITHER.

MAIN UPDATES FOR THE FIRST TWO PERIODS WERE TO TEMPERATURES AND POP
TRENDS.
