AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 158 Pm Edt Tue Apr 16 2024
Synopsis -
high pressure centered near bermuda will continue to extend its axis westward across the local waters through Thursday, keeping a prevailing southerly wind flow in place. Evening wind surges may briefly bring speeds up towards caution levels, especially offshore, by midweek. A weak cold front entering the southeastern states on Thursday may stall over the georgia waters by Friday, resulting in a brief period of light and variable wind directions across our local waters. Southwesterly winds may strengthen somewhat late in the weekend ahead of another approaching cold front, which could bring chances for showers and Thunderstorms by Sunday afternoon and evening.

NEAR TERM
Issued at 130 PM EDT Tue Apr 16 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

Dry weather and mostly clear to partly cloudy skies will continue through today and tonight as high pressure ridging extends over the region. High temperatures this afternoon will reach up into the mid to upper 80s over inland areas and in the upper 70s and lower 80s along the coastline. Potential for morning fog forming over the eastern portion of the forecast area, in the vicinity of the I-95 and US17 corridors. Overnight low temperatures will drop down into the upper 50s and lower 60s for most inland areas and in the lower to mid 60s along the shoreline.

SHORT TERM
(Wednesday through Thursday night)
Issued at 130 PM EDT Tue Apr 16 2024

High pressure ridging should continue to hold across the area through this period. However, the associated high center offshore will break down a bit and nudge southward Wednesday and through Thursday as a cold front tries to scrape the northern part of the region with some shortwave energy aloft. Expecting to be dry enough at the low levels with some lingering subsidence to avoid any showers or t'storms anywhere across the area, however.
Expecting just increased cloud cover for much of Wednesday and into Thursday as showers pass north of interior southeast GA.

Very mild temperatures will continue through the short term as well. Readings well into the 80s and approaching 90 will be in store on WEdnesday, with even more readings in the 90s likely Thursday. The coast will certainly be cooler, but still getting into the 80s all the way to the immediate coast by Thursday.
Overnight lows will also be mild, in the low to mid 60s.

LONG TERM
(Friday through Monday)
Issued at 130 PM EDT Tue Apr 16 2024

Another decaying front and accompanying upper level short wave will try to move across northern parts of the area again on Friday and Friday Night. Though once again, there will be difficulty getting any POPs into our area with high pressure/subsidence lingering. Potential does seem slightly higher for this event however, as high pressure will continue to be nudged towards the south and east of the region and the diffuse boundary stalls just to our north. The stalled boundary should gradually set the stage for increasing precip chances into the weekend with high pressure finally starting to be kicked out to a certain extent and low level moisture returning. Long range guidance is having some difficulty with the location and timing of the front this weekend and into next week, though it does look as though the front will start to make it's way across the area by the start of the work week next week.

The period starts will continued above average temperatures Friday and likely through the entirety of the weekend, coming down closer to normal by Monday.

AVIATION
(18Z TAFS)
Issued at 130 PM EDT Tue Apr 16 2024

VFR conditions will persist through a majority of the forecast period with winds southeasterly afternoon winds becoming more mild in the evening and overnight hours. Potential for early morning fog formation occurring along TAF sites between about 09z-13z with lingering conditions clearing by midmorning.

MARINE
Issued at 130 PM EDT Tue Apr 16 2024

High pressure centered near Bermuda will continue to extend its axis westward across the local waters through Thursday, keeping a prevailing southerly wind flow in place. Evening wind surges may briefly bring speeds up towards Caution levels, especially offshore, by midweek. A weak cold front entering the southeastern states on Thursday may stall over the Georgia waters by Friday, resulting in a brief period of light and variable wind directions across our local waters. Southwesterly winds may strengthen somewhat late in the weekend ahead of another approaching cold front, which could bring chances for showers and thunderstorms by Sunday afternoon and evening.

Rip Currents: Moderate risk of rip currents Today and Wednesday as onshore sea breeze expected during the afternoon hours with surf/breakers around 2 feet.
