The radar

The Maxwell AFB radar (KMXX), 85 km from the middle of the area, began a volume at 20:49 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, 8.8 hours before the alert went out and 154 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 severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Mobile, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 2:28 PM CDT, 1 hour 17 minutes earlier.

Area forecast discussion, May 22, 2:28 PM CDT, 1 hour 17 minutes before

Area Forecast Discussion
National Weather Service Mobile AL
228 PM CDT Fri May 22 2020

.NEAR TERM /Now Through Saturday/...Ridging, both surface and
aloft continues to nose into the area from the east tonight and
Saturday. Deeper moisture is gradually returning to the region in
the predominately south to southeast flow, especially over out
western counties (ie- interior southeast Mississippi). With this
increasing moisture, with daytime heating we have some scattered
showers and thunderstorms across the region this afternoon which
will continue into the early evening hours before dissipating. Our
daily wet microburst checklist came up with a Moderate Risk, so
a few of the storms could produce some strong gusty winds, but the
overall severe threat is low (although a few storms may may
produce a few brief severe wind gusts). By mid evening, most of
the convection will have ended and look for generally rain free
conditions tonight (with perhaps a few coastal showers late).
Expect another round of scattered showers and thunderstorms again
tomorrow as the same pattern continues. Lows tonight will range
from the mid and upper 60s over interior locations to the lower
70s at the coast. Highs on Saturday will continue to be summer
like, with most interior locations climbing into the lower 90s
with mid and upper 80s closer to the coast and some low to mid 80s
along the immediate beaches. /12

&&

.AVIATION...
22/18Z issuance...VFR conditions for the remainder of the day and
into the evening hours. Isolated to scattered showers and
thunderstorms this afternoon and early evening will bring
localized MVFR conditions in and near convection, but generally
brief in nature at any one spot. Overnight more widespread MVFR
conditions could occur with patchy, light fog and some lower
ceilings, but most areas remaining VFR. Light southerly winds
today, becoming light and variable overnight, before becoming more
predominately light south again on Saturday morning. Some
isolated convection again possible early on Saturday morning,
especially down near the coast. /12
