013 FXUS62 KKEY 120254 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1054 PM EDT Sun Aug 11 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 939 PM EDT Sun Aug 11 2024 Although the KBYX radar looked a little more exciting earlier this evening, conditions have calmed down and we have been left with just some spotty, isolated showers and thunderstorms being detected over the distant eastern Florida Straits. Radar is also detecting some residual outflow boundaries from earlier thunderstorms over the peninsula transversing the area just to our north. Keeping this in mind, the 00Z KEY sounding reflects an environment that would support some showers overnight with CAPE just shy of 3000 J/kg and near-zero inhibition. All of this is to say that we are opting to keep the 30 percent PoPs overnight as this looks like a case where a couple of us are woken up by some thunder in the middle of the night. Light easterly breezes will continue as well, and there are no changes that need to be made to the forecast package. && .MARINE... Issued at 939 PM EDT Sun Aug 11 2024 There are currently no watches, warnings, or advisories in effect for the Florida Keys waters. From synopsis, the Atlantic ridge axis continues to extend north of the Keys coastal waters. Gentle to moderate easterly breezes will slacken on Wednesday with breezes veering to northwesterlies on Thursday night as a weak front moves south from the Continental United States towards central Florida. Breezes will become more chaotic by Friday as the ridge axis fractures over Florida. A tropical disturbance to the east of the Bahamas will move north towards Bermuda Friday and Friday night. && .AVIATION... (00Z TAFS) Issued at 939 PM EDT Sun Aug 11 2024 VFR conditions with light easterly near surface winds near 10 mph will prevail through the 24 hour period. Weather conditions should remain dry and quiet overall, but TAFs reflect a window of opportunity for VCSH between 07Z and 13Z. Some isolated showers far off to the east of the terminals could make it to the vicinity during the nighttime and early morning hours, but anything more than that will have to be addressed with short term amendments at a later time. && .PRELIMINARY POINT TEMPS/POPS...
