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, 6.4 hours before the alert went out and 216 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 Apr 16, 12:59 PM CDT, 24 minutes earlier.

Area forecast discussion, Apr 16, 12:59 PM CDT, 24 minutes before

Area Forecast Discussion
National Weather Service Mobile AL
1259 PM CDT Sat Apr 16 2022

.MESOSCALE UPDATE...Over the past several hours convection across
the area has generally been on a downward intensity trend, but we
are just now getting into the most unstable time of the afternoon.

An outflow boundary from previous convection is currently draped
across portions of central MS and into southern AL, and has been
providing the focus for the ongoing shower and thunderstorm
activity.

An upper disturbance moving east across the area this afternoon,
combined with dry air aloft, should allow for the development of
some stronger storms to our west along the boundary through the
course of the remainder of the afternoon. These storms should move
east-southeast into our area this afternoon and into the early
evening hours.

Through the early afternoon hours, some gusty winds of 40 to 45
mph and small hail could be associated with some of the storms
over our area to the northwest of 1-65, but later this afternoon
some could become severe, with strong damaging winds and large
hail being the primary threats. A brief tornado is also possible,
but at this time the tornado threat is relatively low.

Several local regional NWS offices recently discussed the
potential of a Severe Thunderstorm Watch for portions of the
region with SPC, but the overall conditional threat supported by
relatively marginal mid level lapse rates and overall relatively
weak shear, it was decided to delay issuance of a Watch at this
time. That said, there could well be some severe storms, and the
Watch potential may be revisited later this afternoon. /12
