550 FXUS62 KTAE 011026 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 626 AM EDT Tue Jul 1 2025 ...New AVIATION... .NEAR TERM... (Today and tonight) Issued at 147 AM EDT Tue Jul 1 2025 Troughing over the southeastern US along with ample moisture overhead will continue the recent trend of fairly widespread to numerous showers and storms blossoming across the region today. Convection is already ongoing over the waters and near the coast this morning, and additional development is expected across inland areas later this morning and afternoon. The primary hazard will be locally heavy rainfall with forecast PWs in excess of 2 inches, but a few stronger storms with gusty winds can`t be ruled out. Since the region has been in a fairly wet pattern as of late, additional rainfall today over already saturated areas may be a bit quicker to cause flooding. Storms should generally fizzle out over inland areas later in the evening before developing offshore and near the coast again overnight tonight. With high rain chances today, highs should generally remain in the mid 80s to near 90. Deep moisture in the area should keep lows temperatures in the low to mid 70s. && .SHORT TERM... (Wednesday through Thursday night) Issued at 147 AM EDT Tue Jul 1 2025 An upper level trough embedded in northwesterly flow aloft will slowly dig into the southeast US Wednesday into Thursday. As this feature moves into the southeast, a weak frontal boundary associated with this feature will likely slow/stall across north Florida sometime Thursday. The wet pattern we`ve been in recently is likely to continue, especially across Florida, but depending on the speed of the trough and where it stalls, it is possible that drier mid-level air behind the frontal boundary settles in to our southeast Alabama and southwest Georgia counties, reducing rain chances for Thursday afternoon. Regardless, the consistent pattern of heavy rain offshore in the morning hours, transitioning inland through the day, will continue Wednesday into Thursday. && .LONG TERM... (Friday through Monday) Issued at 147 AM EDT Tue Jul 1 2025 Longer term forecast becomes a little more uncertain into Friday and the upcoming weekend as uncertainty in the wake of the stalling front grows. What most guidance is somewhat confident in is the potential development of a weak area of low pressure along this stalling front. However, the location of where this broad surface low develops is still very uncertain. Given this feature will likely be developing along the front, and it being associated with drier air, where the area of low pressure forms will likely determine how high, or not, our rain chances go into the weekend and early next week. While zoning in on deterministic (non-ensemble) models will lead to wildly different forecasts in these types of scenarios and lead times, they can provide insights into potential outcomes. For the overnight runs, development like is indicated on the 00z GFS, where the region remains on the western edges of any development, would potentially yield a drier forecast for us this weekend and into early next week. However, looking at the 00z Canadian solution, where a weak low develops, lingers, and then moves west, would likely yield a wetter scenario for us into the weekend and early next week. Regardless, a slightly drier forecast appears possible into the Independence Day holiday weekend as drier air behind the front settles in with a potential increase in rain chances by late in the weekend and next week depending on the evolution of this surface low. && .AVIATION... (12Z TAFS) Issued at 624 AM EDT Tue Jul 1 2025 A blanket of IFR to LIFR ceilings over much of the area should lift to VFR later this morning. Widespread to numerous showers and storms are expected again today and may intermittently impact terminals throughout the day and into the evening. Otherwise, VFR conditions are expected. && .MARINE... Issued at 147 AM EDT Tue Jul 1 2025 Light to moderate westerly to southwesterly breezes continue across the northeastern Gulf thanks to high pressure anchored in the Atlantic. A weakening cold front approaches Wednesday into Thursday and will increase westerly breezes for the middle of the week. A weak area of low pressure may develop along the remnant front over the northeastern Gulf Friday or Saturday. Otherwise, late night and morning thunderstorms are expected the next several mornings; they`ll come with gusty winds, lightning, and the potential for waterspouts. && .FIRE WEATHER... Issued at 147 AM EDT Tue Jul 1 2025 A fairly wet pattern is forecast to remain in place and should continue to keep fire weather concerns low. A weak front is forecast to push into the area from the northwest Wednesday night into Thursday, which will likely help portions of SE AL and SW Georgia dry out a bit later in the week. && .HYDROLOGY... Issued at 147 AM EDT Tue Jul 1 2025 An H5 low over the Bahamas coupled with an approaching H5 trough from the northwest will keep a wet pattern in place across most of the area through mid-week. Precipitable water values (PWATs) of 1.9" to 2.1" are near the 90th percentile for early July and are forecast to linger into the holiday weekend. Couple that with showers and storms that aren`t expected to move a whole lot and you have the potential for isolated instances of flash flooding. Most guidance suggests several inches, 2" to 4", falling along and south of I-10 in Florida. Some ensemble members paint a couple of coastal communities with 8"+ over the next several days, with the best chances of that occurring across coastal Gulf and Franklin along with Taylor and Dixie counties. Fortunately, 1-hr Flash Flood Guidance (FFG) is over 3" for those locations. On the flip side, 3- hr FFG is generally 4" to 4.5", so any sort of training of storms could lead to instances of Flash Flooding. Confidence wasn`t quite high enough to issue a Flood Watch for those aforementioned counties at this time, but it was considered and one may be needed in the next day or so depending how much rain those locations receive. With most of the rain forecast to fall along or south of I-10, riverine flooding is not currently anticipated. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested.
