The radar

The Miami radar (KAMX), 27 km from the middle of the area, began a volume at 22:26 UTC, the scan nearest the moment this went out.

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

Miami, FL (KMFL), launched 12:00Z, 10.4 hours before the alert went out and 53 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.

What forecasters said that day

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 Miami, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at May 23, 4:31 PM EDT, 1 hour 53 minutes earlier.

Area forecast discussion, May 23, 4:31 PM EDT, 1 hour 53 minutes before

Area Forecast Discussion
National Weather Service Miami FL
431 PM EDT MON MAY 23 2016

.DISCUSSION...

This Afternoon-Tonight: Surface boundary has settled across South
Florida this afternoon, currently from around Naples to Southern
Palm Beach county. The earlier more stratiform convection that was
moving across the region has pushed well east into the Atlantic,
bringing enough clearing in time for peak afternoon sunshine. A
few storms have already developed along the intersection of the
diffuse west coast seabreeze and cold front, with additional
showers popping up along some of the other boundaries across the
region. The east coast seabreeze has also managed to develop and
begin pushing inland.

Best coverage of storms, and threat for stronger storms this
afternoon and early evening will be where the seabreezes collide,
especially in the vicinity of the frontal boundary. This looks to
be towards the western side of the east coast metro across Palm
Beach and Broward counties. Frequent lightning and hail will be
the threats with the strongest storms.

Convection diminishes late this evening with a few Atlantic
showers possible as prevailing flow starts to veer more east-
northeast.

Tuesday: Another unsettled day looks to be store across the region
as the remnant surface boundary remains across South Florida along
with its pooled low level moisture. Low level instability will be
aided by another upper level wave moving across the region, likely
during peak heating in the afternoon.

Surface high pressure building to our north in the wake of the
trough will shift low level flow. So while we still look to get a
Gulf coast seabreeze, the east coast seabreeze looks more
dominant, shifting the best storm chances over the southern
interior and Gulf coast.

With cool temps aloft and weak steering flow, frequent lightning,
small hail, and locally heavy rainfall will be the main concerns
with storms into the afternoon and evening.

Wednesday-Upcoming Weekend: Run to run and model to model
differences continue with the forecast details for the end of the
week into the upcoming weekend, but the overall pattern remains the
same. The main upper level trough will continue to move away from
the east coast, while its southern extent will develop into a cutoff
low near the Bahamas in the Thursday-Friday time frame.

Meanwhile, surface high pressure will build across the Western
Atlantic and bring back breezy easterly flow. Most of South Florida
will be on the subsident side of the aforementioned cut-off low,
which normally translates into a drier pattern establishing across
the area. But the stronger easterly flow should advect enough low
level moisture to support scattered showers and a few thunderstorms.
Rain coverage looks to increase into the weekend as the upper level
trough/low meanders closer to Florida along with its associated
surface trough.

&&

.MARINE...Generally light and variable flow expected through the
overnight hours with frontal boundary overhead, becoming easterly
into Tuesday as high pressure builds over the Western Atlantic.
Gusty conditions will set up from Wednesday onwards with speeds
increasing to around 15kts over the Atlantic, occasionally 15-
20kts at times over all the waters. The strengthening easterly
flow will build seas over the Atlantic to 3-5ft at times beyond
Wednesday.
