GMZ005 Synopsis For Keys Coastal Waters From Ocean Reef To Dry Tortugas 1022 Am Edt Tue May 13 2025
Synopsis - Moderate south to southwest breezes will veer more northwesterly while the heart of the parent low meanders along the northern gulf. Shower coverage with embedded isolated Thunderstorms will continue diminishing in frequency as the afternoon progresses. As the low lifts toward the northeast during the middle of the week, higher pressure will be able to fill in behind it, encouraging drier weather and slackening breezes.

DISCUSSION
Issued at 245 PM EDT Tue May 13 2025 A very uneventful evening is setting up across the Florida Keys following Monday's burst of inclement weather. Temperatures are on track to reach the mid 80s with some of the inland stations reporting mid to upper 70s. On GOES-E satellite, any lingering layers of stratus clouds have dissipated or lifted off to the east with stray cumulus clouds pulsing in their wake. The KBYX radar observations highlight some moderate showers in the distant southeast Straits of Florida. The story for today will be heat and humidity. Dew points are safely in the low 70s across the island chain, and temperatures are likely to reach or exceed the average daily high. Muggy conditions marking summer are on the way, and will arrive sooner than one may think.
In terms of meteorological phenomena, the next seven days contain a number of interesting patterns. The cutoff low responsible for Monday's rainfall and thunderstorms will slowly weaken into an open shortwave trough by Thursday. Meanwhile a building longwave ridge over the Gulf will support a low level jet over KS/OK and support potential severe weather in the Northern Plains to the Midwest. A heat dome will start to build across the Gulf Coast by Friday. What does all of this mean for the Florida Keys?
Well, the pattern suggests very low chances of rainfall, light to gentle breezes across the island chain, and warmer than normal temperatures. Statistical guidance suggests dew points near 70F by Thursday, and near 75F Saturday and Sunday. Ensemble models show southeasterlies developing by Friday, meaning little to no relief from the humidity. The most significant weather patterns will likely be defined by a mixture of Cuban convection, mesoscale land effects from the Florida Peninsula, and possible cloud lines before the winds veer southeasterly. Check back for any updates, and enjoy the easier boating conditions!
MARINE
Issued at 245 PM EDT Tue May 13 2025 No watches, warnings, or advisories are currently in effect for the Florida Keys waters.
From synopsis, gentle breezes and a decrease in shower coverage will define the upcoming week. A stray thunderstorm in the distant southeastern Florida Straits is possible tonight, thus showers were left in the forecast for that period. A low pressure system over the Ohio valley will weaken and lift north mid week, veering breezes from northerly to easterly by Thursday. Breezes will begin to build to moderate over the weekend without an accompanied increase in shower coverage.
AVIATION
(15Z TAFS) Issued at 245 PM EDT Tue May 13 2025 VFR conditions will prevail at the terminals as drier air leads to decreased cloud cover through the TAF period. This also means rain chances are minimal. Winds will remain light through the period, generally from the north to northeast although directions could be somewhat variable at times.
CLIMATE
On this day in Keys Weather History, the daily record rainfall of 3.25 inches was recorded in Key West set back in 2018. Rainfall records for Key West date back to 1873.
Also, the daily record rainfall of 0.59 inches was recorded in Marathon set back in 2018. Rainfall records for Marathon date back to 1951.
