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 Tallahassee, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 22, 3:37 PM EDT, 1 hour 12 minutes earlier.

Area forecast discussion, Jun 22, 3:37 PM EDT, 1 hour 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
337 PM EDT Sun Jun 22 2014

.Near Term [Through Tonight]...

Expect a decent coverage of summer time pulse convection this
afternoon across the area. A few strong to severe storms cannot be
ruled out through this evening given expected SBCAPE values around
3000 j/kg with the best chance across the big bend where the most
destabilization is expected. Convection will begin to diminish after
sunset.

.Short Term [Monday Through Tuesday Night]...

Monday's weather pattern will be quite similar to this afternoon,
with broad, weak troughing across the Southeast. At the surface,
the seabreeze fronts and a weak front across central Georgia and
Alabama will drive convection locally. Expect the highest PoP
coverage where convection from the seabreeze and synoptic front
merge across north-central Florida and south-central Georgia well
into the afternoon. On Tuesday, there may be a bit more synoptic
forcing across the entire Tri-State region as models indicate an
MCV exiting the northeast Gulf. This will likely enhance the
seabreeze fronts and yield a more widespread scattering of storms
away from the seabreezes. Afternoon highs will be in the lower to
middle 90s for most locations.

.Long Term [Wednesday Through Sunday]...

Much of the same for the extended range forecast as the local area
will likely remain sandwiched between an upper ridge and upper
trough, with only weak synoptic forcing. Most afternoons will be
dominated by seabreeze convection. Rain chances will remain near
average with high temperatures in the middle to upper 90s.

&&

.Aviation...
[Through 18Z Monday]

Scattered to numerous showers and thunderstorms are expected from
this afternoon through this evening with convection rapidly
diminishing after sunset. Winds will be light outside of
convection. VFR conditions are expected to prevail outside of
convection.

&&

.Marine...

Relatively light winds and low seas will prevail for the next
several days under the influence of surface high pressure.

&&

.Fire Weather...

No red flag concerns are forecast through the upcoming work week.

&&

.Hydrology...

Rainfall totals for the next 5-7 days will range from 1 to 2 inches
across the area. With all rivers below bank full stage, this
rainfall is not expected to cause significant rises on area rivers.
