.DISCUSSION...
Issued at 1015 AM EDT Mon Apr 22 2024
Current surface analysis places a frontal boundary extending from
around Lake Okeechobee southwestward into the southeastern Gulf of
Mexico. KBYX Doppler Radar is detecting a few showers and
isolated thunderstorms in the zone of best confluence ahead of the
front, mainly in the vicinity of Marco Island in southwestern
Florida. Closer to home, skies are mostly sunny across the island
chain, with temperatures mainly near 80F and light southwest to
west winds.

The aforementioned front will continue to progress southeastward
through this afternoon. However, the 12z sounding at KEY sampled
quite dry air remaining in place across the Florida Keys above
900 mb. Thus, only an isolated shower is expected for most
locations, with the exception of the extreme Upper Keys, which may
see an isolated thunderstorm over the South Florida Mainland then
dive southward and clip a few of those communities. Overall, the
forecast is on track, with no changes proposed for this late
Monday morning update.

.MARINE...
Issued at 1015 AM EDT Mon Apr 22 2024
A weak front will move through the Florida Keys coastal waters
this afternoon, with light to gentle southwest to west breezes
becoming moderate to fresh from the northwest. Fresh to strong
breezes will veer from the northwest this evening to the northeast
by Tuesday morning. Small Craft Advisories may be required for
portions of the marine zones for these periods. Moderate
northeast to east breezes will prevail from late Tuesday night
through Thursday. Strengthening high pressure over the western
North Atlantic will bring fresh to strong easterly breezes to the
Keys marine zones beginning Friday,lasting into the weekend.
Additional Small Craft Advisories may be required for this
extended forecast period.

.AVIATION...
(12Z TAFS)
Issued at 1015 AM EDT Mon Apr 22 2024
Dry weather will prevail across EYW and MTH through the TAF period.
VFR CIGs will dominate, but a weak cold front moving across the Keys
will allow an increase to BKN conditions and possible short-lived
MVFR periods. Near surface winds will veer from southwesterly to
northwesterly in the late morning to northeasterly by overnight
hours.
