The radar

The Jacksonville radar (KJAX), 116 km from the middle of the area, began a volume at 20:00 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

Jacksonville, FL (KJAX), launched 12:00Z, 8.0 hours before the alert went out and 117 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 30, 3:14 PM EDT, 44 minutes before

Area Forecast Discussion
National Weather Service Jacksonville FL
314 PM EDT THU JUN 30 2016

.Near term...Tonight and Friday...Thunderstorms moving ne across
ne FL/se GA will intensify by late afternoon as they encounter
the seabreeze front pinned near the east coast. Expect a few
strong to marginally severe storms with locally heavy rainfall...
strong gusty winds...and frequent lightning strikes in the
stronger cells and mergers. Showers may linger past midnight as
upper shortwave trough moves ne across the area. Friday will also
be an active convective day as another upper impulse moves ne from
the Gulf across a very moist airmass in place over ne Fl/se Ga.

.SHORT TERM...
Friday night...Showers and storms will continue into Friday
evening primarily along and east of I-95 where sea breeze
convergence occurred during the late afternoon. This activity
should diminish around midnight with lack of diurnal heating.
Precip chances increase along the gulf coast late Friday night
into early Saturday morning as a weak shortwave approaches the
Big Bend overnight and deep SW flow pushes activity onshore
towards the I-75 corridor. Continued low temps in the mid 70s
expected.

Saturday through Sunday night...Sfc trough to our north and ridge
to our east will continue deep moist southwesterly flow across the
area this weekend. This pattern will allow showers and storms to
begin earlier in the day...moving inland from the Gulf of Mexico
and spreading area wide throughout the afternoon. Highest precip
chances each afternoon will be along the I-95 corridor as the west and
east coast sea breezes converge late in the day. Activity in this
area should linger into into each evening. Afternoon temps in the
low 90s expected for Saturday coming up a couple degrees on Sunday
as ridge begins to build with trough weakening to our north.

.LONG TERM...
Monday through Thursday...Western extent of stacked ridge builds
in early next week with max temps climbing back up into the upper
90s by middle of next week with heat indices around 105 degrees.
With continued southwesterly flow and PWATS between 1.75 to 2
inches expect scattered afternoon showers and storms each day
triggered by progressing sea breezes. Low temps in the mid to
upper 70s continue throughout the long term period.

&&

.AVIATION...
Tempo thunder at TAF sites this afternoon and early
evening until around 00z...with vcsh til around 04z as convection
weakens after sunset. Prevailing VFR conditions will become
MVFR/IFR in showers as cigs/vsbys lower in heavy downpours.

&&

.MARINE...
Frontal boundary will remain to the north with high pressure to
the se the next few days. A sw flow will persist with daily
seabreezes near the coast. Winds will be mostly 10 to 15 knots
with seas up to 4 feet offshore. Daily rounds of showers and
storms can be expected over the waters through the weekend...
mainly in the late afternoon and evening hours.

Rip Currents: Low through Friday.
