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.

Area Forecast Discussion
National Weather Service Miami FL
217 PM EDT Sat Apr 11 2020

.Short Term...
Today...
A differential heating boundary has develop across central Miami-Dade
County where some clearing of stratiform clouds has allowed
increased heating across Southern portions of the peninsula. On vis
satellite you can also, a well-develop cu field beginning to form.
Winds have become a little backed and easterly at the surface, with
upper level HRRR model winds veering westerly with height. With the
increased heating MLCAPE values have soared to be above 3000 J/kg
over southeastern Florida with 50 to 60 knots of effective bulk
shear. 0-3 SRH values over the southeastern metro are 150-200 m2/s2
and significant tornado parameter (STP) indices around 1 over metro
Miami-Dade. The storm relative mean wind is oblique to the current
boundary axis across Miami-Dade county support semi-discrete
supercell storm mode. There is increasing potential for severe
supercells across southeastern Florida this afternoon, with main
hazards being damaging winds, large hail and even the possibility of
a tornadoes. If multiple round of storms develop over the same area
heavy rainfall may lead to localized flooding of low-lying poor
drainage.

Due to the weak ascent there is still some uncertainty that this
event will materialize.

Sunday and Monday...
High pressure will dominate for the beginning of the week. Even
so, a few showers may be possible in the Lake region. With the
high to the east, a south to southeast flow will bring a warming
trend to the area, helping to boost temps into the upper 80s to
low 90s.

.Long Term (Tuesday through Friday)...
A cold front will stall around north central Florida on Tuesday,
permitting southern Florida to remain in the warm, moist airmass
around the Atlantic surface high pressure. As the week progresses,
a reinforcing front pushes across the southeastern United States
which will allow the boundary to advance southward into southern
and central Florida. The main stories through the rest of the week
will be warm temperatures and increasing rain chances. There is
still some uncertainty with the timing and location of the front
before it stalls. If the location is further south than currently
forecast, rain chances will increase while the increased cloud
cover may help cool temperatures a bit. Either way, the chances of
rain will include the potential for heavy rain as well, especially
with more robust convection like thunderstorms.

&&

.Marine...
Showers and thunderstorms may bring locally hazardous weather to
the Atlantic waters, including Biscayne Bay through this evening.
This includes gusty wind and waterspouts as possible hazards.
Then, conditions improve for the next couple of days as high
pressure builds in. Even so,wind may continue to be a concern for
small craft, as a south to southeast wind of 15 to 20kts is
forecast through at least the first half of the week. Small Craft
Should Exercise Caution, mainly in the Atlantic waters of South
Florida.

&&

.Aviation...
Unsettled weather is forecast across South Florida through the
evening hours. Strong gusty showers and possibly some isolated
strong to severe thunderstorms are possible, mainly south of
Alligator Alley. The hazards include hail, downbursts, and funnel
clouds are possible. Also, an isolated tornado can not be ruled
out. Active weather is possible well into the overnight hours.
Tomorrow should see quieter weather, but the wind is forecast to
be breezy out of the southeast.

&&

.Beach Forecast...
A southeast wind is forecast to strengthen for the next few days.
this would keep an enhanced risk of rip currents for the Atlantic
beaches for at least the first half of the week.
