969 FXUS62 KTAE 171907 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 307 PM EDT Tue Jun 17 2025 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE, FIRE WEATHER... .NEAR TERM... (Through Wednesday) Issued at 305 PM EDT Tue Jun 17 2025 The region will continue to be situated between an upper level ridge across the western Atlantic and Florida Peninsula, and an upper level trough across the central US. This will lead to broad southerly flow across the region and a continuation of scattered showers and thunderstorms. Like today, the greatest rain chances should be across southeast Alabama and the Florida Panhandle where deep-layer moisture content will be higher compared to further east. However, unlike today, a weak surface trough rounding the upper level ridge could lift north into the area tomorrow. This could allow slightly better shower and thunderstorm coverage across the Florida Big Bend compared to this afternoon, but confidence in this is somewhat low and even then, chances will not increase much over this afternoon`s observed chances. Similar to today, coverage will follow a diurnal pattern and the mean southerly flow will help activity quickly spread into Alabama and Georgia by the early afternoon hours. && .SHORT TERM... (Wednesday night through Thursday night) Issued at 305 PM EDT Tue Jun 17 2025 On Thursday the CWA will be positioned on the edge of two ridges - the subtropical high to our east and an approaching ridge to our west. In addition, a weak trough will be positioned to our north over the Midwest and moving eastward. PWATs will have recovered somewhat on Thursday after a brief respite Tuesday/Wednesday, climbing up to a modest 1.8-1.9" thanks to continued southwesterly flow. Still, large scale subsidence will be prominent as both ridges influence the region. A subtle shortwave looks to shoot northeastward from the gulf into our CWA on Thursday which may provide a slight convective boost, but uncertainty exists in how exactly this feature will evolve and what effect it will have. All this considered, rain chances are expected to be slightly higher than Tuesday/Wednesday, but still lower than earlier this week/last weekend. The pattern will be more akin to normal summertime patterns, with a mostly clear morning making way for afternoon showers and thunderstorms most favored at or along the seabreeze front. && .LONG TERM... (Friday through Monday) Issued at 305 PM EDT Tue Jun 17 2025 By Friday, the aforementioned trough will be exiting the CONUS to the east, nudging the subtropical high far enough away to the east to stop influencing our region. A very weak and ill-defined front will also be draped over the SE as the trough exits. Eventually, the front should stall and wash out, but it is possible it could act as an axis of increased convergence and lift for shower and thunderstorm activity on Friday if it is strong enough and can push far enough south into our region. Following the trough`s exit, a dominant H5 ridge quickly establishes over the Mid-Atlantic this weekend. Large scale subsidence again becomes the driving synoptic feature, and without southerly winds to advect higher PWAT air, rain chances should remain much more muted and seasonable through early next week. The bigger story with this pattern is the growing threat of excessive heat. By the weekend, high temperatures will climb into the mid-upper 90s, with apparent temperatures well exceeding 100 and potentially even approaching heat advisory criteria for some locations. && .AVIATION... (18Z TAFS) Issued at 215 PM EDT Tue Jun 17 2025 VFR conditions will prevail through the most part at area terminals. Scattered TSRA is possible at DHN/ABY/ECP this afternoon with lower chances across eastern terminals of TLH/VLD. Any thunderstorms would likely bring brief IFR/MVFR visibilities. VFR conditions and quieter conditions return tonight as TSRA activity winds down. Brief moments of MVFR conditions after sunrise are possible at all terminals from 12-16z Wednesday as low-level cumulus from early morning heating develops. && .MARINE... Issued at 305 PM EDT Tue Jun 17 2025 Light to gentle southerly to southwesterly breezes remain over the northeastern Gulf through the middle of the week thanks to a sprawling surface high in the western Atlantic. The high gets pushed south on Friday, allowing for more westerly breezes to take over. Winds become easterly to southeasterly by Saturday as strong high pressure sets in to the north over the Mid-Atlantic. Daily chances of showers and thunderstorms continue, especially during the overnight and morning hours each day. && .FIRE WEATHER... Issued at 305 PM EDT Tue Jun 17 2025 A wetter pattern as of late, light winds, and elevated afternoon humidities will keep fire weather concerns low through the next few days. Only concerns would be higher dispersions across some of our Georgia counties where lower rain chances and drier air could allow elevated dispersions. && .HYDROLOGY... Issued at 231 AM EDT Tue Jun 17 2025 Despite somewhat lower rain chances the next few days, locally heavy downpours remain a concern thanks to precipitable water values exceeding the 50th percentile for mid-late June. Some quick ponding on the roads and minor flooding of low-lying areas is possible due to the slow movement of the showers and storms. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
