AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 159 Am 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.
Gulf stream -

69 nautical miles east northeast of flagler beach. 73 nautical miles east of saint augustine beach. 85 nautical miles east southeast of jacksonville beach. 103 nautical miles east southeast of st simons island.

High pressure ridge axis from the Atlantic will extend westward across or just to the North of SE GA/NE FL region through tonight with a warm South to Southeast steering flow that will continue above normal temps. Mostly clear to partly cloudy skies as periods of mainly thin high cirrus will continue to stream across the region over the top of the large high pressure ridge to the west of the region. Highs into the mid/upper 80s over inland areas with lower 80s along the Atlantic Coast as the East Coast sea breeze will push well inland with SE surface winds increasing to 10-15G20 mph behind the sea breeze during the afternoon hours. Periods of high cloudiness will continue tonight with SE winds decreasing to 5 mph or less, combined with low temps around 60F and increased low level moisture from the onshore flow should lead to some patchy/areas of fog formation mostly likely along the I-95/US17/US301 corridors towards sunrise Wednesday morning, could be some locally dense fog in some spots, but amount of any significant fog formation will depend on the coverage/thickness of high cloud cover during the overnight hours.
SHORT TERM
(Wednesday through Thursday night)
Issued at 227 AM EDT Tue Apr 16 2024
Wednesday, some patchy to areas of fog east of highway 301 will lift by mid morning as temperatures warm quickly through the 70s after starting around 60. The low level ridge will nudge eastward closer to Bermuda while mid level ridging aloft extending across Florida from the southern Gulf of Mexico will deflect an eastbound shortwave trough trailing from the upper Midwest into the mid MS valley to our north late in the day into Wednesday night. The surface high pressure ridge axis will extend from the center of the high near Bermuda WSW into NE FL and cause the local low level flow to turn more southerly. This will allow Atlantic seabreeze to move inland past US 17 towards highway 301 corridor while the Gulf coast seabreeze moves inland just past I-75 by late afternoon with breezes yielding 10-15 mph winds from the southeast and the southwest directions, respectfully. Highs will be in the mid to upper 80s inland and near 80 at the coast.
Wednesday night, southwest flow above the surface will favor some patchy fog developing mainly just west of our area from the Gulf coast under increasing mid and high level cloud cover. Lows will be in the lower 60s inland and mid 60s at the coast.
Thursday, low level ridging will shift back over northern FL in the morning and then move into the NE Gulf of Mexico through the day as a mid level shortwave impulse moves east off the southeast coast and supports a quick moving weak cold front that will pass just north of the area to the Carolina coast. This will allow the day to begin with initially mostly cloudy skies as mid level clouds linger, but no rain expected as lower atmosphere stays too dry from influence of the low level ridge. The low level flow pattern will become west southwesterly with a pinned Atlantic seabreeze confined to the beachfront communities. Highs therefore will be warmer Thursday with upper 80s to around 90 degree readings east of highway 301 to I-95 corridor while the immediate coast is a bit less warm in the low to mid 80s from the Atlantic seabreeze.
LONG TERM
(Friday through Monday)
Issued at 227 AM EDT Tue Apr 16 2024
Friday, light westerly low level flow relaxes some compared to Thursday with low level ridging just to the south over central and southern FL with light westerly winds inland and the Atlantic seabreeze gaining a little more ground inland to I-95. Keeping silent pops over our area as showers stay north of the Altamaha due to subsidence under the ridge capping development of showers or thunderstorms. Hot readings expected as highs reach the low 90s along and west of I-95 with upper 80s along the Altamaha basin and mid 80s at the beaches. Lows will be in the low to mid 60s.
Saturday, low level ridge will move eastward away from the FL peninsula and allow for a few showers and an isolated T'storm to form over SE GA in the afternoon where greater moisture increases ahead of the upstream cold front entering the deep south. Highs stay hot in the low 90s inland and mid 80s coast. Lows will be in the mid 60s.
Sunday, the cold front will sink towards our area with isolated to scattered coverage of showers and thunderstorms for most of the area. Slightly more clouds Sunday compared to Saturday will help lower highs to the upper 80s to around 90 and mid 80s at the beaches. Lows will again be in the mid 60s.
Monday, the cold front will sink through NE FL in the afternoon and the combination of moisture ahead of the boundary, instability from cooler mid level temperatures, and lift from convergence along the cold front will generate scattered showers and T'storms. Highs will be cooler as winds turn about from the southwesterly to northerly with cooler highs in the mid to upper 70s over SE GA and the low to mid 80s over NE FL.

VFR weather conditions today with occassional ribbons of thin high cirrus clouds moving in from the northwest through the period with light winds becoming southeasterly 8-12 knots this afternoon in the 16-19Z time frame. Winds will weaken to 4-8 knots and turn southerly after 00Z-02Z with patchy to areas of fog late tonight yielding VFR to MVFR level visibilities 4-6 miles after 08Z-10Z.

High pressure ridge axis across or just north of the local waters will continue a South to Southeast flow through Thursday with speeds at 10-15 knots and seas 2-4 ft. Weak frontal boundary will push through the SE US Thursday Night and stall just north of the waters Friday and Saturday with a weak Southwest flow expected, along with local Southeast to South sea breezes near the Atlantic Coast. No headlines expected through the period.
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.
