The radar

The Jackson/Brandon,MS radar (KDGX), 135 km from the middle of the area, began a volume at 02:03 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 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.

.DISCUSSION...
Issued at 215 PM CDT Sun Jul 12 2026

Today through Saturday night: A frontal boundary sinking into the
region from the north is yielding more scattered to widespread
showers and storms across the CWA. Due to the very humid and
unstable environment across the region, in addition to some steep
mid-level lapse rates (6-6.3 C/km), isolated severe storms will be
possible, with damaging wind gusts being the primary concern with
the most intense storms. Heavy downpours and frequent lightning
can both be expected with any of today's convection, and have
added a limited threat HWO graphic to account for some flash flood
potential as moisture convergence will peak along the I-20
corridor this evening. I

While this frontal boundary will eventually washout, due to the
overall troughing/low pressure pattern over the region, combined
with the continued humid and unstable airmass each day, solid
chances for showers and storms will remain in the forecast into at
least Wednesday.  While severe storms currently aren't forecast
after today, given the again overall setup across the region, a few
storms could become intense enough Monday through Wednesday to
produce some gusty winds.  Once again, both heavy downpours and
frequent lightning can be expected with any convection.

Finally, Thursday into the start of next weekend, ridging aloft will
again reassert itself over the region.  While this will lessen the
overall rain chances across the forecast area, the trade-off
currently looks to be a return to hot humid conditions as highs
areawide eventually climb back into the middle 90s Saturday. This
also currently looks to bring back some concern for increased heat
stress yet again during this extended portion of the forecast.
