The radar

The Columbus AFB radar (KGWX), 40 km from the middle of the area, began a volume at 19:37 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

Birmingham, AL (KBMX), launched 12:00Z, 7.6 hours before the alert went out and 174 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.

Skew-T log-p

Temperature in red, dew point in green, the mixed-layer parcel dashed.

What forecasters said that day

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

NWS Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 11, 11:36 AM CDT, 2 hours 58 minutes earlier.

Area forecast discussion, Jul 11, 11:36 AM CDT, 2 hours 58 minutes before

Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
1136 AM CDT MON JUL 11 2016

.Discussion...Made some really small adjustments to the forecast for
today. Models were not in good agreement on rain chances and
coverage. Tried to use a blend. Leaning heavily on the hi-res,
tweaked the coverage. There was some isolated activity associated
with a weak disturbance moving across the northern portions of the
cwa...increased pops a category in the northwest zones. The HRR has
convection blowing up in the west/southwest in the afternoon and
propagating into the east through the early evening. Clouds probably
limited convection this morning, but clouds were breaking up and
temperatures were climbing quickly. Morning sounding shows some
elevated instability, so limited severe still seems good. With clouds
and fog holding in the east, lowered the highs a degree or two, but
kept values around 90. Updated zones were already out.

&&

.AVIATION...MVFR conditions over KMEI will slowly rise to VFR by
16Z. Otherwise, VFR ceilings will prevail through the afternoon and
evening. Scattered to numerous TSRA will develop by afternoon and
pose a risk of brief lowering of ceiling and visibility to IFR/MVFR
at the impacted TAF sites. These conditions should last until 12/02Z
with MVFR ceilings and visibilities in stratus and fog developing
after 12/06Z./26/
