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.

.UPDATE/DISCUSSION...
Issued at 525 PM CDT Fri Aug 21 2026
Ongoing this afternoon, keeping a close eye on convection ongoing
generally along and north of the I-10 corridor. Plenty of support
in place for strong to severe thunderstorms, including ample dry
air entrainment per recent GOES-16 Precipitable water, resulting
in extremely high DCAPE across central MS/AL and plenty of
available instability. Environmental favorability for severe
weather is in place, but focus will be on any outflow boundary
and/or seabreeze interactions to individual, pulse-like severe
storms causing damaging downburst winds. REFS guidance/trends
slides all convection south late this afternoon/evening, but not
entirely sure this will happen as they interact with the post-
seabreeze environment along the coast, with low confidence on
this activity sagging south through the evening. If it does, the
severe threat will transition into coastal marine areas around
sunset with ongoing gusty winds the main risks.
Drier air filters into the area tomorrow through Sunday,
resulting in lower forecast PoPs and greater PBL mixing to cause a
reduction in the heat risk. Not anticipating the need for an
advisory tomorrow as heat indices range in the 103-106 range,
still hot though. Could still see an isolated storm along the
seabreeze, but keeping PoPs in the 10-20% range both Saturday and
Sunday afternoons.
Monday into next week, focus shifts to the northwest as we could
likely see distinct PVA/impulses riding around the periphery of
the ridge across the four corners region. This could introduce a
series of long-distant MCS's from the central MS valley region
into the northern Gulf coast. Something we'll need to carefully
monitor for Monday and Tuesday.
Mid to late week, we return right back to the typical summertime
pattern but again with ongoing impulses from the north. Afternoon
heat indices remain below criteria/heat risk impacts remain
limited throughout the week with highs in the low 90's, but PoPs
remain elevated with daily localized strong to isolated severe
storm risks. KLG

(18Z TAFS)
Issued at 1249 PM CDT Fri Aug 21 2026
VFR conditions will mostly prevail this afternoon, and after a
line of convection passes through the region late this afternoon
until late evening. We are expecting numerous showers and
thunderstorms to develop north of Highway-84 by late afternoon and
move southward to the coast through this evening. Added a PROB30
group to the KMOB/KBFM/KPNS/KJKA sites for the early- to mid-
evening hours for IFR visibilities (could briefly become VLIFR),
MVFR ceilings and gusty northerly winds to 35 knots. /22
