Area Forecast Discussion National Weather Service Jacksonville FL 1036 PM EDT Mon Jun 11 2018 .Update... Late evening surface analysis depicts the westward extension of Atlantic subtropical ridging extending across south Florida. Meanwhile, a surface trough remains in place from central Georgia eastward across upstate South Carolina, with a backdoor cold front beginning to push southward into coastal portions of the Carolinas. Aloft...a broad trough remains in place over our region, with positive vorticity centers located just off the South Carolina coast and also over southeast Texas. Convection firing along the surface trough over Georgia this afternoon pushed outflow boundaries southward, and this has resulted in slow moving thunderstorms crossing the Altamaha River into northern Jeff Davis, Appling and western Wayne Counties. Convection elsewhere started much earlier today, with activity pushing into the Atlantic waters and dissipating late this afternoon. Mostly mid and high cloudiness remains in place where convection has ended, with temperatures and dewpoints mostly in the 70s. Short-term, high resolution guidance has done a poor job handling the convection along the Altamaha River basin this evening, and slow movement of the activity over our northern counties will keep the threat for localized flooding in place through at least midnight. Otherwise, a similar weather pattern will prevail later tonight and Tuesday, as nocturnal convection develops along the Florida Big Bend coast and potentially pushes inland into the western Suwannee Valley towards sunrise. Convection will then loosely organize along outflows from this activity and the Gulf coast sea breeze during the late morning and early afternoon hours over the Suwannee Valley and our southern Georgia inland counties. Convection will progress east-northeastward at 10-15 knots during the afternoon hours, with activity likely pulsing during the mid to late afternoon hours along the Interstate 95 corridor as convection encounters a pinned Atlantic coast sea breeze. Model soundings indicate relatively cool temperatures aloft...around -8 to -9 degrees Celsius, which could again promote the potential for wet microbursts and prolific cloud to ground lightning strikes over the coastal counties when activity pulses tomorrow. Highs will generally reach the upper 80s to around 90 before convection develops. && .Aviation... MVFR visibilities are expected to develop at VQQ and GNV after 06Z. A brief period of MVFR visibilities will be possible at the rest of the northeast Florida terminals towards sunrise. VFR conditions will then prevail area-wide by 13Z. Showers and thunderstorms will be possible at the regional terminals after 16Z. We used VCTS at each terminal during the afternoon hours on Tuesday, as timing and intensity remain in question. Light southwesterly surface winds will prevail after sunrise. The Atlantic sea breeze will develop towards noon, with surface winds shifting to southeasterly at SGJ towards 16Z and south- southeasterly at SSI and CRG towards 18Z-19Z before thunderstorms potentially develop. && .Marine... The evening south-southwesterly wind surge has increased speeds to near Caution levels, mostly over the offshore waters. We expect winds will gradually diminish after midnight. Otherwise, a rather stagnant weather pattern will prevail through midweek, as the Atlantic ridge axis remains in place to the south of our local waters and a weak trough persists just north of our Georgia waters. Offshore winds will prevail during the morning hours, with the Atlantic sea breeze developing over the near shore waters by early afternoon. Showers and thunderstorms will again approach the near shore waters from the west during the mid to late afternoon hours on Tuesday and likely again on Wednesday. A backdoor cold front currently pushing slowly southward across the coastal Carolina region will approach the southeast Georgia waters on Friday and will push into the northeast Florida waters by early Saturday, with onshore winds developing in the wake of this front during the upcoming weekend. Rip Currents: Low risk will continue at the southeast Georgia beaches this week, with a low-end moderate risk possibly developing at the northeast Florida beaches on Tuesday afternoon as a small southeasterly ocean swell migrates into the near shore waters. && .PRELIMINARY POINT TEMPS/POPS...
