805 FXUS62 KJAX 121931 AFDJAX Area Forecast Discussion National Weather Service Jacksonville FL 331 PM EDT Wed Jun 12 2024 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE... .NEAR TERM... Issued at 326 PM EDT Wed Jun 12 2024 For the latest NE FL and SE GA Daily Key Messages please visit: https://www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf Elevated east to northeast winds 10-15 and gusting to 25 mph at the coast will continue this afternoon as a stalled frontal boundary remains across NE FL near I-10 while a weak low spirals east northeast from central FL along I-4. Ample tropical moisture in place around 2.00 inches in PWATs along and south of the frontal boundary will allow for numerous showers to form as moist onshore flow moves over strong diurnal low level instability with numerous T`storms developing inland south of I-10 and pushing south and west towards I-75 from Gainesville to Ocala. Some storms may bring brief wind gusts 40-50 mph due to strong low level instability, however not expecting severe impacts from wind as mid level temperatures are warmer than average near -6 Celsius and mid level lapse rates are unimpressive. Drier air north of the front will limit chances for showers and T`storms to scattered coverage north of the FL/GA state line with silent pops north of Waycross where PWATs are under 1.50 inches. Overall rainfall forecast for NE FL south of I-10 has trended down with general amounts of a quarter to a half inch and localized higher amounts of 1-2 inches possible in heavier thunderstorms due to slow storm movement and high moisture levels south of a line from Gainesville to Palatka to Palm coast where WPC still maintains a marginal risk of excessive rainfall. Lighter rainfall amounts under a quarter inch expected into SE GA. High temperatures will be cooler at the coast in the upper 80s with low 90s west of I-95 and mid 90s west of I-75 over NE FL. Tonight, T`storms will wane after sunset and dissipate as they shift to the Gulf coast from I-75. Skies will remain partly to mostly cloudy overnight from left over mid and high level debris clouds from earlier T`storms. Showers and thunderstorms will shift north over the local waters with scattered showers and a few isolated T`storms moving onshore towards sunrise as the weak low shifts towards the Gulf stream waters. && .SHORT TERM... (Thursday through Friday night) Issued at 326 PM EDT Wed Jun 12 2024 A front will remain stalled over north central Florida on Thursday as a broad low pressure continues to move off the Atlantic coast. Higher moisture content will stay in place over the Florida peninsula allowing for numerous showers with embedded thunderstorms both Thursday and Friday. Onshore flow will keep coastal high temperatures in the mid to upper 80s, with inland highs climbing into the lower to mid 90s. The highest rainfall totals and threat for localized flooding will be over Marion county and southern Flagler and Putnam counties. && .LONG TERM... (Saturday through next Wednesday) Issued at 326 PM EDT Wed Jun 12 2024 Temperatures will briefing heat back up into the mid to upper 90s (near 100 in inland SE GA) on Saturday as the front passes to our south, lowering precipitation chances for Georgia, however scattered thunderstorm potential will remain over NE FL. The rest of this period will have near normal temperatures will daily afternoon thunderstorm chances across NE FL and most of SE GA. && .AVIATION... (18Z TAFS) Issued at 127 PM EDT Wed Jun 12 2024 A few showers and thunderstorms are developing near the Jacksonville Metro area and also over the coastal waters east of Jacksonville Beach. The offshore storms are slowly working their way back toward the coast and thus have introduced tempo groups for the Jacksonville Metro Fields. Otherwise not much has changed with the thinking for today as our tropical low passes south of our area and high pressure builds in to our north.The pressure gradient between the two will keep winds from the ENE and they gusty into the evening hours, dropping off a bit after sunset. && .MARINE... Issued at 326 PM EDT Wed Jun 12 2024 Weak tropical low will shift offshore this evening and slowly organize offshore of the southeast coast through the rest of this week. See the latest NHC outlook for details on the low. High pressure will remain to the north through this evening and keep breezy east to northeast winds over the local waters with showers and thunderstorms spreading northward tonight from the northeast florida waters into the Georgia waters. A stalled front over the waters will allow for showers and thunderstorms over the waters through Friday. Stronger high pressure will build south from Eastern great lakes on Saturday and push the frontal boundary south of the local waters with decreasing chances for showers and thunderstorms. Light easterly winds Saturday will become breezy on Sunday into early next week as the high builds down the eastern seaboard and then shifts northeast of the region next week. Rip Currents: Moderate rip current risk today with breezy winds from the east northeast. A moderate risk is expected again on Thursday from the east to northeast onshore flow. && .PRELIMINARY POINT TEMPS/POPS...
