| Area Forecast Discussion National Weather Service Key West FL 129pm EDT Tuesday May 12 2026 .PREVIOUS Issued at 421am EDT Tuesday May 12 2026 Weather is a bit more active than the past couple of nights. KBYX radar returns are detecting isolated showers pulsing up and down across the waters of the Florida Keys. One managed to form directly on top of Key West in the early morning hours. Most of these showers have a life cycle of about 30 minutes. This pulse of moisture will, at least, make sure another warm low record is not broken at Key West. Temperatures along the island chain are measuring in the lower 80s. Dew points continue to hover in the lower to mid 70s. Breezes along the reef are light to gentle southeasterlies. Overall, one can expect another warm and muggy day with highs approaching 90 F. Synoptically, Florida Keys weather continues to be defined by a deep anticyclone located north of Hispaniola. Despite the moisture near the surface, drier layers of air continue to linger in the lower to mid levels of the atmosphere. Meanwhile, high pressure systems over the eastern United States are weakening and moving into the Atlantic. For the Keys, this means the pressure gradient is collapsing. Resulting winds are slackening along the island chain, and periods of light and variable winds are possible before mid- week. Weather during the second half of the week will become a bit more complicated. The lack of a strong synoptic pressure gradient suggests local features will become more important, a paradigm where model ensembles typically struggle. In addition, a weak boundary is forecast to stall over Central Florida. This suggests stronger breezes along the southern end of the Peninsula and a shift to westerly winds. Unfortunately, this does not mean we are entering the wet season. Model ensembles continue to move deeper layers of dry air across the Keys late this week. We still have a bit of time before the wet season kicks in. In the meantime, make sure to stay hydrated. Marine Issued at 1115am EDT Tuesday May 12 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys waters. From synopsis, breezes are light to gentle across the Florida Keys waters. The lack of a strong pressure gradient suggests variable conditions are possible tonight, but a shift towards westerlies is expected on Wednesday. Local freshening of breezes near South Florida is possible during the middle of the week. Shower chances will remain on the lower side while drier air masses linger over the Keys.
