What happened

The episode as NWS KEY wrote it up.

The combination of a departing mid latitude upper trough, a lingering upper trough to the southwest of the Florida Keys, little or no convective inhibition and precipitation water above 2.1 inches resulted in concentrated heavy convective rainfall within the city of Key West.

.DISCUSSION...
Issued at 1045 AM EDT Fri Jun 5 2026
Scattered showers with occasional isolated thunderstorms have
continued on this morning throughout the offshore and nearshore
waters of the Keys. GOES-19 Visible Satelitte reveals mostly
cloudy skies. Temperatures across the island chain are in the
lower 80s with dew points in the mid 70s making for a "cooler"
June day. Along the Reef, easterly breezes near 15 knots have
been prevailing outside of slightly higher gusts due to
convection. As the day continues on, shower activity is expected
to start waning in coverage and strength and by tonight rain
chances will be near normal for this time of year. Gentle to
moderate breezes will continue through the weekend.

&&

.MARINE...
Issued at 1045 AM EDT Fri Jun 5 2026
No watches, warnings, or advisories are currently in effect for
the Florida Keys. From synopsis, an expansive eastern United
States surface high will move off the Carolina Coast today and
then push out into the Atlantic over the next few days. As a
result mostly moderate easterly breezes, will gradually give way
to gentle to moderate easterlies this weekend. The recent bout of
increased shower and thunderstorm activity is nearing its end, and
convective potential will fall closer to normal through this
period. Early next week the high will have pushed out into the
Atlantic and weak troughing is expected to set up over Cuba and
the Bahamas. This will tip breezes a bit further southeasterly
with, initially, some additional slackening.

.AVIATION...
(15Z TAFS)
Issued at 1045 AM EDT Fri Jun 5 2026
VFR conditions will prevail at both EYW and MTH through the TAF
period. Showers are still possible at either terminal therefore
VCSH is included at both and TEMPOs for direct impacts will be
included if/when needed. Near surface winds will continue to be
northeast to east at near 10 knots.
