753 FXUS62 KKEY 110300 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1100 PM EDT Thu Jul 10 2025 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1059 PM EDT Thu Jul 10 2025 An interesting afternoon and evening for the Florida Keys. We had not one, not two, but three additional cloud line events. Each cloud line developed along and just north of the Lower Keys. The first one occurred just after 2 pm, another just before 7 pm, and the last one occurring around 930 pm. The cloud line event at 2 pm was the most "exciting" one as it produced several embedded thunderstorms. The other two did not have enough lift to create any thunderstorms. In the wake of the last cloud line, winds surged out of the east. Currently seeing generally 10 to 15 knots at all of our reporting marine platforms. Radar activity has quickly quieted down, however, moisture continues to move in associated with a weak easterly wave. We should see a rash of showers and isolated thunderstorms develop within the next few hours and linger into the morning hours on Friday. It remains to be seen the extent of the shower coverage overnight. The latest hi-res CAM is eager with a resurgence in convection occurring. This is at odds with earlier runs which showed hardly anything developing overnight. Moisture is plentiful and there`s decent instability, but we lack organized lift. Therefore, have opted to keep PoPs where they are at this time. && .MARINE... Issued at 1059 PM EDT Thu Jul 10 2025 A weak tropical wave will continue to push westward through the Florida Keys coastal waters overnight. A moisture plume associated with the wave, in conjunction with modestly freshening east to southeasterly breezes, will support elevated shower and thunder coverage through Friday. Drier air will move in over the weekend, resulting in reduced rain and thunder chances. Winds will subside to light to gentle for the weekend into early next week. && .AVIATION... (00Z TAFS) Issued at 1059 PM EDT Thu Jul 10 2025 VFR conditions will be the predominant through the overnight. Showers are expected to develop late overnight but confidence on timing and coverage is too low to include mentions in the forecast at this time. Otherwise, east to southeast winds have surged and will continue into Friday. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
