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

Tallahassee Rgnl, FL (KTLH), launched 12:00Z, 11.8 hours before the alert went out and 98 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.

Area forecast discussion, Jun 22, 7:30 PM EDT, 15 minutes before

Area Forecast Discussion
National Weather Service Tallahassee FL
730 PM EDT Mon Jun 22 2020

.AVIATION...
[Through 00Z Wednesday]

A line of storms is forecast to impact VLD in the next hour,
otherwise, VFR will prevail behind the line of storms through much
of the night. Early in the morning there may be periods of MVFR
ceilings at all terminals, but should scatter shortly after
sunrise. Tomorrow, another round of storms will be possible moving
through the region from west to east.

&&

.PREV DISCUSSION [724 PM EDT]...

.NEAR TERM [Through Tonight]...

Updated grids and zones to increase PoPs this evening based on
current radar coverage and trends. Most convection should either
move east of our CWA or diminish by 10 pm.

.SHORT TERM [Tuesday night through Wednesday night]...

Another active day is expected on Wednesday with similar synoptic
conditions in place compared to Tuesday. A few stronger storms with
gusty winds remain possible on Wednesday. Highs will generally range
form the mid 80s to low 90s with overnight lows in the low to mid
70s.

.LONG TERM [Thursday Through Monday]...

Upper level troughing and deep layer moisture remain in place on
Thursday which should yield another day of scattered convection
across the area. Some drier air is expected to work into the area
for Friday and Saturday, resulting in lower rain chances. Moisture
may increase somewhat again for Sunday into early next week with
near average rain chances around 30-50%.

.MARINE...

Southwest winds of 10 to 15 knots will prevail through Wednesday
with mainly 10 knots or less after Wednesday for the remainder of
the period. Seas will mostly be in the 1 to 2 foot range, except
locally higher in and near thunderstorms.

.FIRE WEATHER...

Red flag conditions are not expected for the next several days.

.HYDROLOGY...

A seasonably wet pattern is expected through Thursday with an
increased chance of daily afternoon showers and thunderstorms.
Localized pockets of heavy rain are possible, but flooding is not
expected to be a widespread concern.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur (while following all local, state, and CDC guidelines) by
calling the office or tweeting us @NWSTallahassee.
