Issued at 1037 PM EDT Sun Aug 24 2025 A much different scenario played out tonight for the Florida Keys. Southerly winds during the day kept cloud streamers north of the island chain. Some of these streamers came to life but again most of the activity stayed off the islands for the most part and out over water. Meanwhile, lurking in the shadows was an outflow boundary that was steadily marching southeast across the Gulf basin towards our waters. Unlike yesterday, this boundary will not as robust as yesterday`s and did not produce much as it came into our waters. It did attempt to re-fire over the last couple of hours but has since fizzled away. Across the island chain and surrounding marine platforms, we have light and variable winds with speeds generally around 5 knots (or 5 mph). Aloft we still have quite a bit of debris clouds from convection that fired to our north and is being filtered down across our area. This will likely prevent temperatures from bottoming out as opposed to light winds and clear skies. This light and variable wind regime will be short lived as southeast to south breezes will return late overnight and into early Monday morning. Contemplated dropping PoPs but given the number of boundaries present across our waters and nearby the Florida Keys, have decided to keep 20 percent for now. && .MARINE... Issued at 1037 PM EDT Sun Aug 24 2025 A weak subtropical ridge will remain over the Keys through early to mid week. This will result in generally light breezes, occasionally becoming light to gentle as well as variable at times. Towards the latter half of the week, the ridge over the Atlantic will strengthen slightly as a tropical wave moves through the northwest Caribbean Sea. This will result in a freshening winds with occasionally gentle to moderate breezes. Also, increasing moisture is expected to lead to more widespread showers and thunderstorms, especially late week. && .AVIATION... (00Z TAFS) Issued at 1037 PM EDT Sun Aug 24 2025 VFR conditions will prevail through the overnight and into Monday morning with light and variable winds eventually becoming southerly again. && .KEY WATCHES/WARNINGS/ADVISORIES...
