The nearest sounding before it

Tallahassee Rgnl, FL (KTLH), launched 12:00Z, 3.9 hours before the alert went out and 111 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.

Mesoscale Discussion 0913

Areas affected...portions of the FL Panhandle into southeast AL and
southwest GA

Concerning...Severe potential...Watch unlikely 

Valid 251551Z - 251715Z

Probability of Watch Issuance...20 percent

SUMMARY...Locally strong gusts will be possible into the afternoon
hours with stronger storms. The overall threat is expected to remain
limited, precluding the need for a watch at this time.

DISCUSSION...A cluster of thunderstorms across the central FL
Panhandle has shown at least brief organization recently. This
activity has intensified within a plume of stronger destabilization
where temperatures have warmed into the upper 70s and low 80s amid
low 70s surface dewpoints. While some locally strong gusts may occur
into the afternoon across parts of the FL Panhandle into southeast
AL and southwest GA, overall severe potential is expected to remain
limited/brief. Effective shear magnitudes will remain weak over the
region while low and midlevel lapse rates are poor. This will limit
the longevity of any stronger/organized convection. Nevertheless, a
very moist and moderately unstable airmass could still support a few
strong gusts. At this time, a severe thunderstorm watch is not
expected.
