Issued at 1224 AM EST Sun Dec 7 2025 A frontal boundary extends across the central Florida peninsula just north of the Sarasota area and has been sinking very slowly south. It should become stationary just south of the Sarasota area in the next couple of hours with boundary layer winds north of the boundary out of the northeast, and to the south of the boundary out of the south. This will be the demarcation between areas of fog developing south of the front by sunrise which will be locally dense, and low clouds/patchy fog north of the boundary. A dense fog advisory may be needed for areas south of the frontal boundary later tonight. The fog/low clouds will lift by mid morning today, however mostly cloudy skies will persist through the afternoon...although skies may become partly cloudy across southwest Florida for several hours before the clouds spread over that region. The frontal boundary across the central peninsula will dissipate today with winds shifting to the south and southeast across the region as a much stronger cold front currently over the southeast U.S. begins to push down across north Florida with an increasing chance of showers and possibly a few thunderstorms mainly across the nature coast. The cold front will push south across the Florida peninsula Sunday night and early Monday. Numerous to widespread showers and isolated thunderstorms will spread across the forecast area ahead of the front. High pressure will build over the Florida peninsula in the wake of the front Monday and Monday night with clearing skies and cooler drier air advecting across the region. The area of high pressure will hold over west central and southwest Florida through mid week with temperatures running near climatic normals with highs in the mid to upper 60s north to the mid 70s south...and lows in the 40s north, lower to mid 50s central, and upper 50s to around 60 south. A gradual warming trend will develop late in the week ahead of the next cold front which is expected to move across the area Friday and Friday night. && .MARINE... Issued at 1224 AM EST Sun Dec 7 2025 A cold front will push across the waters late today and tonight with showers and isolated thunderstorms spreading over the region from north to south. Winds will shift to the north/northwest in the wake of the front Monday and Monday night and will increase to cautionary levels. Winds/seas will subside Tuesday and Tuesday night. High pressure will hold over the waters through mid week with no headlines expected. && .PRELIMINARY POINT TEMPS/POPS...
