Small Craft Advisories will likely be needed. && .DISCUSSION... Issued at 936 AM EST Tue Nov 25 2025 Surface analysis places a weak frontal boundary stretching from northern Florida eastward to the central North Atlantic. This feature is very weak, with a strong area of high pressure centered off the Virginia coastline in its wake. Return, anticyclonic flow around this feature is pumping in gentle east to southeast breezes across the Florida Keys at this late Tuesday morning hour. KBYX radar is detecting a few isolated showers, supported by a low- level veering profile sampled in this morning`s 12z sounding conducted at KEY. Outside of these isolated showers, skies are partly cloudy across the Keys, with temperatures already nearing their maxima for the day in the lower 80s.Y et another rather routine forecast for today. Enjoy the quiet, tranquil weather, as changes are likely coming beginning late Thanksgiving, when a period of windy and unsettled conditions at times will commence. && .MARINE... Issued at 936 AM EST Tue Nov 25 2025 There are no watches, warnings, or advisories in effect across the Florida Keys local waters. From synopsis, ridging extending across the Florida Peninsula will continue to gradually pull away over the next couple of days. As this happens, the pressure field across the area will weaken, and our gentle to moderate easterly breezes will become light to gentle by Wednesday morning. These conditions won`t last long, as a cold front associated with a deepening trough will push through the Florida Keys coastal waters late on Thursday. Breezes will freshen drastically late Thursday as the front approaches, and the end of the week will see a period of fresh to strong breezes, along with an increase in shower activity. Small Craft Advisories may be required as early as Thursday night, then lasting through at least Sunday. && .AVIATION... (15Z TAFS) Issued at 936 AM EST Tue Nov 25 2025 Although a light passing shower cannot be ruled out in the vicinity of either terminal throughout the TAF period, VFR conditions will prevail. Near-surface winds will remain generally out of the east to southeast near 10 knots. && .PRELIMINARY POINT TEMPS/POPS...
