623 FXUS62 KTAE 101039 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 639 AM EDT Fri May 10 2024 ...New AVIATION... .NEAR TERM... (Today and tonight) Issued at 353 AM EDT Fri May 10 2024 Watching two areas of convection at the moment, one across central Alabama and one further west into central/southern Mississippi and will gradually enter western Alabama. Outflow from earlier storms runs north of Apalachicola northwest into central Alabama. Dewpoints east of this boundary in the low to mid 60s and dewpoints west are in the mid 70s. MLCAPE in the area runs from 1000-2000 J/kg with higher readings further west. Some inhibition east of the outflow and much less further west. The outflow boundary is expected to slowly move back north and east overnight as a mid level disturbance approaches and southerly winds become more dominant ahead of this feature. Assessing the latest CAMs, convection over central Alabama will drift southeast and into our northern counties before 1AM. Some questions on how far south this convection can go into our area before significantly weakening as the atmosphere east of the outflow boundary is more stable. Additional convection may fire into the panhandle in that same timeframe while convection in southern Mississippi/western Alabama races towards the area towards 5AM. These two areas congeal through the night while convection in Texas races along the Gulf coast towards the area in the morning hours. The enhanced risk from SPC remains overnight with destructive winds 70-80+ mph along with tornadoes and large hail. Residents are urged to have several ways to receive warnings, and make sure these devices and means are charged and the volume is up loud as much of this will be occurring at night. These systems have the potential to produce widespread damage along its track. Appears the MCS will push through the area in the morning hours, trends continue to show residual showers and storms develop into the afternoon hours. Flooding may become an issue depending on how the MCS evolves and moves across the area and convection that develops behind the it. Keep pops going further west into the afternoon hours and may have to expand if convection does develop further west into the panhandle. Pops will be winding down Friday night as a cold front moves through. Highs will be in the 80s today and lows tonight will fall in the low 60s. Dewpoints fall into the mid 50s behind the front so it will feel like a crisp morning into Saturday morning. && .SHORT TERM... (Saturday through Sunday night) Issued at 353 AM EDT Fri May 10 2024 Being post-frontal will lead to relatively cooler temps and a decrease in moisture as northerly flow prevails throughout the short term. Although surface winds will be southerly near the coast during the afternoon hours due to the sea breeze, high pressure will lead to large-scale subsidence. Limiting development to fair weather Cu or developing towers that fizzle away. Overall, a nice weekend is on tap. Expect daytime highs generally in the 80s with overnight lows generally in the upper 50s to low 60s. && .LONG TERM... (Monday through Thursday) Issued at 353 AM EDT Fri May 10 2024 Next week a parade of shortwaves looks to move across the north Gulf states with several rounds of weather possible. Given upper-level support and good instability and decent low-level shear there`s a fair chance for multiple rounds of severe weather. Given the mesoscale nature of these disturbances it`s far too early to get into specifics, however, once we get into Tuesday and beyond we`re looking at an active period. Expect daytime highs initially in the upper 70s to mid 80s on Monday to climb back up into the upper 80s to low 90s by Thursday. Similarly, expect overnight lows initially in the low to mid 60s initially climb into the upper 60s to lower 70s by Thursday. && .AVIATION... (12Z TAFS) Issued at 635 AM EDT Fri May 10 2024 QLCS line has passed DHN/ECP/ABY and is bearing down on TLH and VLD through 12Z. Expect damaging winds to possibly accompany the line and have it in the TAFs. Once the line goes through, expect several hours of SHRA and VCTS but should decrease later today. Some CAMs show additional development along the coast which would affect ECP/TLH through the morning so may have to amend to keep TSRA longer at these locations. Winds will eventually veer to the northwest with time as the rain moves out. Degraded flight conditions as would be expected will gradually improve later today. && .MARINE... Issued at 353 AM EDT Fri May 10 2024 A cold front will slowly approach from the northwest today, preceded by strong to severe thunderstorms over the waters. Cautionary conditions could be possible throughout today into tomorrow morning. The front will limp across the waters on tonight. It will be followed by moderate to occasionally fresh northerly breezes on Saturday morning. Surface high pressure over the southern Plains on Saturday will move across the Southeast States on Sunday, causing winds to clock around. High pressure will move east into the Atlantic on Monday, brining a return to southerly flow. && .FIRE WEATHER... Issued at 353 AM EDT Fri May 10 2024 Through early this afternoon, thunderstorms are expected to increase in coverage and intensity as a complex of storms moves through the region. Severe storms including destructive winds, hail, and isolated tornadoes will all be possible. By late afternoon or early evening, the rain will move east of the Florida Big Bend with drying conditions into the weekend. The weather pattern will remain unsettled into next week with several rounds of wetting rains and possible severe weather. && .HYDROLOGY... Issued at 353 AM EDT Fri May 10 2024 A marginal risk of excessive rainfall is place today for most of the area as a frontal system looks to push through the region. The primary risk here being torrential downpours or training within any thunderstorm(s) leading to a localized flash flooding risk. Otherwise, area rivers are expected to remain below flood stage. In the extended period the WPC is forecasting 3-5 inches by midweek next week. This could introduce some riverine concerns, however, it`s too far out to say with any degree of confidence. && .SPOTTER INFORMATION STATEMENT... Spotter activation is requested. Spotters should safely report significant weather conditions and/or damage by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
