Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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

Jackson, MS (KJAN), launched 12:00Z, 9.2 hours before the alert went out and 136 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.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Sep 3, 2:02 PM CDT, 2 hours 12 minutes before

Area Forecast Discussion
National Weather Service Jackson MS
202 PM CDT Wed Sep 3 2025

...New DISCUSSION, AVIATION...

.DISCUSSION...
Issued at 121 PM CDT Wed Sep 3 2025

An anomalously deep upper-level trough remains the dominant
feature over the CONUS and should remain so into this weekend.
Various shortwaves rounding the trough will keep rain chances in
the broader Deep South region through the weekend, with best
chances for rain in our forecast area being today and then Friday
Night into Sunday.

Tonight - the rain today is associated with a weak surface trough
and axis of pooled deep moisture. As afternoon and evening rain
comes to an end and clouds thin out, fog will be a concern. Have
included an "Elevated" threat for areas of dense fog across
northeast LA, and western/central MS overnight. Patchy fog is
possible elsewhere in MS and southeast AR.

As the trough axis translates eastward, high pressure from Canada
will build south into the Great Lakes region for early next week,
and upper-level ridging will begin to overspread the central
CONUS. The combo should result in drier weather next week and some
cooler weather again by early week. /NF/

.AVIATION...
(18Z TAFS)
Issued at 121 PM CDT Wed Sep 3 2025

Local radar scans are currently showing scattered SHRA and -TSRA
across portions of east and south MS. As of 1750Z, all TAF sites are
reporting VFR conditions. Several TAF sites could see conditions
briefly drop down to MVFR status between 18Z - 00Z. Otherwise, VFR
conditions will prevail across central MS through the entire TAF
period. /CR/
