The episode as NWS TBW wrote it up.
Easterly flow and deep moisture allowed for scattered thunderstorms to develop across the Florida Peninsula during the afternoon, pushing west through the early evening. One of these storms produced damaging wind gusts as they neared the Gulf Coast. Another storm produced hail to the size of pennies.

Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
300 PM EDT Mon Aug 27 2018
.DISCUSSION (Tonight-next Monday)...
Mid/upper level ridge will remain over the southern U.S. and Florida
through the period with surface high pressure remaining off the mid-
Atlantic and southeast U.S. coast. This will continue the deep layer
east to southeast flow with ample moisture moving westward across
the region. This combined with daytime heating will support
scattered to numerous diurnal sea breeze driven showers and
thunderstorms each day. The flow will remain strong enough to keep
the west coast sea breeze close to the coast so the highest rain
chances will continue to be generally west of the Interstate 75
corridor during the late afternoon and early evening hours.
Convection will gradually dissipate as it moves west out into the
Gulf waters during the each evening with mostly clear to partly
cloudy skies overnight. Main concerns with the storms will continue
to be locally heavy rainfall, frequent lightning, and strong gusty
winds. Daytime high temperatures will be in the upper 80s to lower
90s through the period with overnight lows mostly in the 70s.
&&
.AVIATION...
Scattered showers and thunderstorms will cause MVFR/local IFR
conditions along with gusty winds up to 30 knots into this evening.
Some more MVFR ceilings will be possible once daytime heating gets
underway Tuesday morning, otherwise mainly VFR conditions are
expected. The east to southeast winds will persist at 6 to 10 knots,
but will try to shift to onshore at TPA, PIE and SRQ this afternoon.
&&
.MARINE...
Surface high pressure from the Atlantic extending west across the
southeastern U.S. will maintain an east to southeast flow across the
eastern Gulf waters through the week with a weak onshore sea breeze
component developing right along the coast each day during the late
afternoon. Wind speeds will remain 15 knots or less with seas 4 feet
or less, except in the vicinity of showers and thunderstorms. No
headlines are expected.
&&
.FIRE WEATHER...
No fire weather hazards are expected for the next several days as
relative humidity values will remain well above critical levels.
