FXUS62 KKEY 150813 AFDKEY Area Forecast Discussion National Weather Service Key West FL 413 AM EDT Wed Apr 15 2026 ...New DISCUSSION, MARINE, AVIATION... .KEY MESSAGES... - Winds over the next 24 to 48 hours will tend to lull during the late morning and afternoon hours, then peak in the early evening and overnight. - Little to no measurable rain will maintain continued moderate drought conditions in the Florida Keys for the next week. - Temperatures will remain near to slightly above normal, with highs in the lower 80s, and lows in the lower to mid 70s. && .DISCUSSION... Issued at 413 AM EDT Wed Apr 15 2026 A broad high pressure remains centered over by Bermuda and stretches back to the west-southwest across the Florida Peninsula and Gulf waters. This had been maintaining moderate to occasionally fresh easterly breezes across the Florida Keys these past few days. Meanwhile, stacked overhead in the mid and upper levels is a ridge that has been suppressing any upward vertical movement. This on top of the very limited moisture that has been rounding the ridge has equated to very low if not near nil rain chances. Today we will see much of the same in terms of sensible weather. Deep layer subsidence on top of already limited moisture will result in little more than sprinkles at best through the day. Overnight we may get enough nocturnal instability to produce very shallow and isolated showers, but even these will do little to accumulate. Meanwhile, the surface high across the Atlantic and Gulf will be at times bifurcated by a thermal trough across the Peninsula due to daytime heating. This will lead to winds lulling through the morning and afternoon, then peaking in the late evening and overnight hours. Towards the end of the week and into the weekend, a broad and weak easterly wave will approach and stall in the vicinity of the Bahamas. Though this feature will not reach the Keys proper, some moisture from this wave will leach and slide westward at times. This may allow for some showers to pass through at times Friday through Sunday. On top of this, the low level steering flow will remain north to northeast and any showers or thunderstorms that develop across the mainland during the afternoons could also slide across the Upper Keys at times. Early next week a backdoor front looks to slide through the Florida Keys with a slight uptick in rain chances but also a period of freshening breezes. && .MARINE... Issued at 413 AM EDT Wed Apr 15 2026 A broad high pressure sitting across the western North Atlantic and into the Gulf Basin will maintain easterly winds this week and into the weekend. Breezes will tend to lull during the morning and afternoon, then peak in the late evening and overnight. This will result in mainly gentle to moderate breezes with some periods of moderate to occasionally fresh across the Straits of Florida. High pressure will slide further east towards the weekend, allowing for breezes to slacken. This is expected to be brief as the next high quickly builds in from the Southern Plains on Monday. && .AVIATION... (06Z TAFS) Issued at 413 AM EDT Wed Apr 15 2026 VFR conditions expected through the forecast period. Winds will remain generally from the ENE at near 10 knots with occasional gusts to near 20 knots. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
