No meaningful changes. The forecast is in good shape.

SHORT TERM (Through Thursday Evening)... With high pressure over the area, and very low atmospheric moisture, the weather should remain quiet through at least Thursday evening. Given the recent rain yesterday, fog is possible in the interior areas tonight.

Tomorrow should see a warming trend, with the highs in the 80s almost everywhere across the area.... LONG TERM (Thursday Night through Wednesday)... Through Saturday Night... A few weak shortwaves traversing the southern fringes of an upper-level low over the Great Lakes Region will help push a cold frontal boundary across northern FL Thursday night before stalling somewhere between central/northern FL. With South FL remaining in the warm sector with warm/moist SW flow, increasing rain and storm chances are expected this weekend along with patchy morning fog, primarily across western/inland locations, each morning. However, keeping silent Probability of Precipitation areawide for Saturday as high pressure still maintains enough influence over the area.

Temperatures will climb from the upper 80s with some lower 90s inland on Friday to widespread lower to mid 90s on Saturday. Some areas right near the coast may stay in the upper 80s due to sea breezes. There is a potential that temperatures could climb high enough to threaten some records this weekend, especially with forecast temps running almost 8 to 10 degrees above average for this time of year.

Sunday through Mid Next Week... By Sunday, a deep upper-level trough will dive through the SE CONUS which will aid in a developing surface low over the tail end of the aforementioned stalled frontal boundary. Eventually this low and newly reinvigorated cold front will push towards the FL peninsula, with the low crossing through the central/northern half of the state into the Atlantic and the front pushing SE towards South FL. However, model consensus keeps the stubborn frontal boundary to the north of the CWA and Lake Okeechobee. With warm SW flow continuing and the front refusing to budge, rain and storm chances will stick around, albeit a very messy forecast to round out the long term.

Overall, there is a potential for a few days of rainfall across the area that will need to be monitored. With the increasing rain chances, warm temperatures capable of supporting sea breeze development, and the potential for some supporting dynamics aloft, the threat of thunderstorms also is increasing as the forecast period ends. With that said, did cap PoT thunder at 30 percent as this is toward the latter half of the long term period.

The cloudy skies and rain will help suppress high temperatures Sunday through mid-next week with highs mostly in the 80s.... AVIATION(18Z TAFS)... Generally dry/VFR. Patchy ground fog possible for inland areas tonight but this should remain away from the terminals. Light winds overnight becoming easterly tomorrow around 15 kt. The exception is at KAPF where a Gulf Breeze should turn winds inland around 18 tomorrow.
