992 FXUS62 KTAE 250506 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 106 AM EDT Tue Jun 25 2024 ...New AVIATION... .UPDATE... Issued at 906 PM EDT Mon Jun 24 2024 The only change to the previous forecast was to add south Walton county to the heat advisory for Tuesday with heat index values expected to exceed 108 there. && .NEAR TERM... (Through Tuesday) Issued at 358 PM EDT Mon Jun 24 2024 The frontal boundary that is currently pushing south through the region today is expected to become quasi-stationary across North Florida on Tuesday. This will provide a focus for showers and thunderstorms to develop during the afternoon and evening hours across the Florida Panhandle and Big Bend. Areas north of the Florida border will likely remain dry as dry air behind the frontal boundary advects into SE Alabama and SW Georgia tonight. This dry air will allow for deep layer mixing and very hot daytime high temperatures, with 100 degrees forecast for much of this region. Upper 90s to near 100 are expected for much of the Florida Panhandle and Big Bend as some cloud cover may keep temperatures slightly cooler in these areas. Regardless, the moisture in place across the Florida Panhandle and Big Bend will lead to dewpoints in the low to mid 70s. Dewpoints this high combined with upper 90s to near 100 degree high temperatures will lead to heat index values in the 108- 112 range across these aforementioned zones. Given these values, a heat advisory has been issued for a large portion of the Florida Panhandle and Big Bend for Tuesday. Those working or playing outside for any length of time should take frequent breaks in the shade or air conditioning and stay hydrated. Thunderstorm activity has the highest chances of developing across the Florida Big Bend on Tuesday. Forecast soundings are showing concerning values of DCAPE and SBCAPE across the Florida Panhandle and Big Bend on Tuesday with values in the 1400-1700 J/Kg range of DCAPE and 3000-4000 J/Kg of SBCAPE currently forecast. These values will bring the potential for damaging wind gusts and even some isolated hail with plenty of dry air aloft supporting hail growth. While deep layer shear is around 15 knots, and not significant, these values of DCAPE and SBCAPE coupled with an inverted V sounding will promote the potential for strong damaging winds with any storms that can develop in this environment. && .SHORT TERM... (Tuesday night through Wednesday night) Issued at 358 PM EDT Mon Jun 24 2024 Several shortwaves rounding the base of a trough across the Great Lakes Region will bring with them a frontal feature that looks to aid in forcing for ascent. This will lead to scattered showers and storms, primarily across our Florida counties where instability and moisture are more abundant. Strong gusty winds are the primary hazard of concern with this storms as high lapse rates and inverted- V sounding profiles are expected. Expect overnight lows generally in the mid 70s with daytime highs generally in the mid to upper 90s. && .LONG TERM... (Thursday through Sunday) Issued at 358 PM EDT Mon Jun 24 2024 The aforementioned frontal feature is expected to remain stalled across the southeast, leading to unsettled weather through Friday. Thus, showers and storms are expected to remain scattered, with the highest PoPs being along the sea breeze, primarily within our Florida counties. Once we get into this weekend upper level ridging looks to begin building over the region. This will introduce large- scale subsidence and inhibit convection for the eastern half of our area. Conversely, areas along the Florida Panhandle and SE Alabama have better chances of seeing scattered showers and/or storms where PWATs and instability looks to be higher. There`s also the chance that the SE FL Big Bend sees some activity due to the Atlantic sea breeze being enhanced due to the placement of the upper-level ridge. Expect daytime highs generally in the mid to upper 90s with overnight lows generally in the mid 70s. && .AVIATION... (06Z TAFS) Issued at 103 AM EDT Tue Jun 25 2024 VFR conditions are expected over the next 24 hours. Some models hint at maybe a brief bout of low stratus near TLH around 10-12z, but confidence in this is rather low. TSRA will develop near the FL terminals this afternoon with strong gusty winds possible. Otherwise, light west to southwest winds are expected for TLH, ECP, and VLD with winds becoming more west to northwest for DHN and ABY. && .MARINE... Issued at 358 PM EDT Mon Jun 24 2024 Mainly southwesterly winds should hold through tonight before teetering between westerly and southwesterly afterwards. Seas will generally be between 1 to 3 feet, with the 3 foot waves being favored west of Apalachicola. However, long-period swells will continue through the period as a disturbance sits off northeast Mexico. Nightly chances of showers and storms will be possible over the waters with the highest chances east of Apalachicola. && .FIRE WEATHER... Issued at 358 PM EDT Mon Jun 24 2024 High dispersions are expected across SE Alabama and SW Georgia Tuesday as mixing heights reach near 8000 feet across these regions. Transport winds will predominantly remain below 10 mph out of the west/southwest on Tuesday. Showers and thunderstorms look likely across the Florida Big Bend and portions of the Florida Panhandle on Tuesday as the trailing frontal boundary becomes quasi-stationary across north Florida. Overall, outside of thunderstorm activity and high dispersions across the aforementioned regions, there are no fire weather concerns at this time. && .HYDROLOGY... Issued at 358 PM EDT Mon Jun 24 2024 Diurnal pop-up thunderstorms could lead to localized flooding concerns where slow moving storms could produce several inches of rainfall. Otherwise, there are currently no river flooding concerns. && .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...
