The radar

The Miami radar (KAMX), 97 km from the middle of the area, began a volume at 23:16 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

Key West, FL (KNQX), launched 12:00Z, 11.3 hours before the alert went out and 155 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.

.KEY MESSAGES...
Updated at 343 PM EST Sun Mar 1 2026

    - High Rip Current Risk along Atlantic beaches this week.

    - Hazardous conditions for small craft across Atlantic waters.

&&

.SHORT TERM...
(Rest of today through Monday)
Issued at 343 PM EST Sun Mar 1 2026

Convection this afternoon was limited to areas south of a decaying
frontal boundary, and east of a differential heating boundary
resulting from the lingering fog/stratus across southwest FL this
morning. An upper-level shortwave moving across Florida provided
enough deep-layer shear and cool enough mid-level temperatures
that a couple of the storms were able to produce pea to nickel
sized hail from Homestead to Miami Beach. As the front sags
further south, continues to weaken, and a more stable environment
settles in, expect the shower and thunderstorm activity to
continue diminishing through the early evening. A break in showers
should last through most of the night, though a scattering of
showers is expected along the east coast in the morning/early
afternoon associated with flow moving west across a low-level
thermal trough. The showers should diminish by early afternoon as
diurnal heating reduces the upslope component of the easterly
flow. Later in the day on Monday, the Gulf breeze will clash with
the background easterly flow to allow for a few showers and an
isolated storm to develop across southwest FL. In the absence of a
shortwave, expect 500mb temps to warm a little bit and deep-layer
shear to decrease. Thus, the threat for strong to severe storms
will be less than this afternoon.

&&

.LONG TERM...
(Monday night through Saturday)
Issued at 1218 AM EST Sun Mar 1 2026

Breezy northeast flow continues through at least mid-week as the
surface pressure gradient remains tight. There will be a chance (30-
40%) for showers each day through the period as ample moisture
remains with highest chances across local Atlantic waters and along
the immediate east coast due to the breezier east-northeast flow.
Surface flow veers more easterly towards the end of the week as
surface high pressure across the western Atlantic builds westward.

High temperatures should remain in the low 80s for east coast metro
areas, however due to the long duration easterly flow, a warming
trend is expected for interior and Southwest Florida and highs could
approach the upper 80s to low 90s by the end of the work-week.

&&

.AVIATION...
(18Z TAFS)
Issued at 100 PM EST Sun Mar 1 2026

Thunderstorms and associated restrictions will be most likely from
OPF through TMB over the next few hours. There after, VFR should
prevail at all terminals through a majority of the night.
Scattered light showers and MVFR ceilings will be possible down
the east coast early tomorrow morning through early afternoon.
Winds may gust around 20 knots from time to time tomorrow
afternoon as well.

&&

.MARINE...
Issued at 1218 AM EST Sun Mar 1 2026

Expect a scattering of showers and isolated thunderstorms each
day and night. High pressure will spread across the Southeast this
week and a strong easterly flow regime will become established.
This will likely spread Small Craft Advisory conditions across
the Atlantic waters.

&&

.BEACHES...
Issued at 1218 AM EST Sun Mar 1 2026

High risk of rip currents and elevated surf expected along
Atlantic beaches this week as strong onshore flow develops.
