Area Forecast Discussion National Weather Service Jacksonville FL 358 PM EDT Sat Jun 10 2023 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE... .NEAR TERM... Issued at 352 PM EDT Sat Jun 10 2023 Scattered to numerous convection has begun over much of northeast FL and over southeast GA close to the FL/GA border along and south of a stationary front. This will continue to be the main area of focus for showers and storms through this evening. Mid and upper level winds will begin to shift more southwesterly through this evening, which will result in a storm motion more east to northeasterly throughout the day. The nearly stalled front will begin to lift northward tonight as a warm front, which will shift our winds to a more southwesterly direction and impact the weather over the next few days. More on that below. Temps have already peaked along the I-95 corridor into the mid to upper 80s, with inland areas topping out near to slightly above 90. && .SHORT TERM... (Sunday through Monday night) Issued at 352 PM EDT Sat Jun 10 2023 Sunday: The aforementioned front lifting northward through Sunday will shift the mean flow more southwesterly including at the mid levels. This will also surprisingly advect some drier than usual air above the surface northeastward over most areas for Sunday and Sunday Night, but especially south of I-10. The main impacts from this will be a bit of a suppression in diurnal convection, especially considering that a shortwave impulse will be passing overhead in the afternoon and evening hours. However, despite the layer of drier air in place, PWATS will still be about 1.4-1.5 inches and therefore the shortwave is still expected to trigger afternoon convection. The best chances look to be over interior areas east of the Suwannee River Valley towards I-95 approaching the mostly pinned easterly sea breeze. Also, areas over southeast GA where slightly better dynamics and more moisture will be in place aloft will have a slightly higher chance for a t'storm. Temps will be slightly warmer Sunday with a mainly offshore flow, except along the immediate coast. Monday: The warm front shifts north and eastward Monday, with a cold front from the same parent low over the northeast then approaching southeast GA counties during the day on Monday. With more favorable dynamics shifting offshore with the previous shortwave and a relatively drier slot in place over northeast FL, diurnal showers and storms will be mainly confined to along and north of I-10. Monday will be an even warmer day for most as southwest offshore flow continues, into the 90s for almost all. Monday Night, most convection with wean with just some lingering showers overnight along the front, and seasonably mild low temps. && .LONG TERM... (Tuesday through next Saturday) Issued at 352 PM EDT Sat Jun 10 2023 By Tuesday, the aforementioned front will slow progress and stall almost directly over the CWA. The area will essentially remain in the zonal flow at the base of an upper trough by Tuesday and persisting through most of the week, with several embedded shortwaves moving around the base of the trough and increasing the chances for showers and storms at times. In short, a seasonably active pattern will be in place for the coming week, with temps also trending near to slightly above average during the long term period. && .AVIATION... (18Z TAFS) Issued at 216 PM EDT Sat Jun 10 2023 Showers and thunderstorms will continue to develop near the Duval County terminals and GNV through the early evening hours. TEMPO groups have been placed in the TAFS at these terminals through 00Z for briefly gusty winds and MVFR visibilities during heavier downpours. Brief periods of IFR visibilities will be possible if stronger thunderstorms move over these terminals. Confidence was not high enough to include anything other than vicinity coverage at the SGJ terminal, but please check for amendments as the afternoon progresses since convection will progress eastward towards the I-95 corridor late this afternoon. VFR conditions should prevail through at least 02Z at SSI, but a few showers and possibly even a thunderstorm could approach from the west after sunset tonight. Fog and low stratus ceilings are expected to develop at VQQ after 07Z Sunday and at GNV towards 09Z. Fog and low stratus ceilings may spread eastward towards JAX, CRG and SGJ by around sunrise on Sunday. Confidence was only high enough to indicate MVFR visibilities at JAX at this time. East-northeasterly surface winds will increase to 10-15 knots at the coastal terminals by 19Z. Outside of developing thunderstorm activity, surface winds will shift to west-southwesterly and will increase to around 10 knots at GNV towards 20Z as the Gulf coast sea breeze crosses the terminal. Surface winds will shift to south- southeasterly during the evening hours before diminishing overnight. Southwesterly surface winds will then develop after sunrise on Sunday and will increase to 5-10 knots by 16Z. && .MARINE... Issued at 352 PM EDT Sat Jun 10 2023 A stalled front over southern GA will lift northward overnight tonight and Sunday, which will shift winds to a more southeast to southerly direction over waters and persist chances of showers and thunderstorms. A cold front will approach northern waters Monday Night and stall through Tuesday. Periods of active weather will persist over waters through late week as severak disturbances move eastward along the stalled boundary. Rip Currents: Rip current threat will be low to moderate for area beaches through Sunday, and likely into early this upcoming week. && .PRELIMINARY POINT TEMPS/POPS...
