.DISCUSSION...
Issued at 931 AM EDT Thu Apr 3 2025
Muggy weather continues today over the Florida Keys. Temperatures
along the island chain are on track to reach the mid 80s with dew
points lingering in the mid 70s. A pronounced 1035 mb high over
the North Atlantic continues to generate fresh to strong
southeasterly breezes across the CWA. Wind gusts overnight peaked
at 29 knots along the reef and over Key West International
Airport. The pattern over our waters is stable, and aside from the
occasional stray cumulus cloud, skies are mostly sunny. The 12Z
KKEY sounding sampled an environment with a PWAT just above the
50th percentile for the day, so stray showers cannot be ruled out.

Overnight weather will remain rather persistent. The pressure
gradient will remain tight as the surface high will take a few
days to shift east, so windy conditions will remain overnight.
Lows will remain in the upper 70s thanks, in part, to fresh to
strong southeasterly breezes. Low level moisture will remain
throughout the night so cloud cover remains in the forecast, and
stray showers will remain across the CWA. Thus, no changes were
made to the forecast for the afternoon update. Just don`t stare
directly into the wind near the waves if you wear glasses; you`ll
be clearing a lot of salt spray.

.MARINE...
Issued at 931 AM EDT Thu Apr 3 2025
A Small Craft Advisory remains in effect for all the Florida Keys
coastal waters through this evening. From synopsis, sprawling
high pressure remains entrenched across the North Atlantic for the
next several days with some minor fluctuations in strength. As a
result, expect a very healthy pressure gradient leading to fresh
to strong east to southeasterly breezes across the Florida Keys
marine zones. Fresh to strong breezes are expected through Sunday
morning, when a low pressure system develops over the eastern
United States. Shower chances will remain near nil until next
week, and a frontal passage may occur sometime around Monday to
Tuesday.

VFR conditions will prevail at both EYW and MTH today. While a stray
shower or two cannot be ruled out, they will be too light and
sporadic to mention in either TAF at this time. Near surface winds
will be out of the east to southeast at 15 to 20 knots with frequent
gusts near 25 knots.
