AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 208 Pm Edt Fri May 10 2024
Synopsis - A cold front to the north of the area will progress southeastward across our local waters tonight. Ahead of the front breezy southwest flow will prevail across maritime waters through Sundown with small craft exercise caution levels ahead of the cold frontal passage. Thunderstorms possible during the afternoon hours over the adjacent fl waters ahead of this front, but mainly south of saint augustine. Winds shift to the northwest at scec levels after midnight tonight behind the cold frontal passage and spread across the local waters. Winds will shift to northerly Saturday morning, with weak high pressure the expected to build eastward over waters on Saturday night, and persisting through Sunday. This weather pattern will result in onshore wind development on Sunday afternoon, with onshore winds then strengthening on Monday night ahead of an approaching warm front. Showers and Thunderstorms will overspread our local waters by late Monday night as this warm front lifts northeastward across our area.

AVIATION
(18Z TAFS)
Issued at 225 PM EDT Fri May 10 2024

VFR conditions will prevail through at least 21Z. Another round of convection is expected to develop along the Interstate 10 corridor after 21Z, with this activity expected to push southeastward towards the GNV and SGJ terminals during the 23Z-02Z time frame.
We included TEMPO groups at GNV and SGJ, with confidence too low to indicate anything other than vicinity thunderstorm coverage at this time. This convective activity is expected to remain south of SSI. Convection will push south of the northeast FL terminals by 04Z, followed by a brief period of MVFR ceilings around 2,000-3,000 feet and possibly a few showers in the 05Z-09Z time frame. VFR conditions will then prevail at the regional terminals by 10Z Saturday. Gusty westerly winds sustained at 15-25 knots will shift to southwesterly and will subside around 10 knots towards 00Z. Winds overnight will shift to northwesterly and then northerly towards sunrise on Saturday.

SHORT TERM
(Saturday through Sunday night)
Issued at 313 AM EDT Fri May 10 2024

The cold front will have essentially cleared the region by the start of Saturday, with weak high pressure building in throughout the day. The pressure gradient behind the front will not be particularly strong, and therefore winds will not really increase diurnally, and in fact may subside a bit throughout the day. The more northerly component with the wind should allow a bit of a sea breeze to develop, though will likely not penetrate much further inland than the I-95/St. Johns River corridor. Otherwise, a mostly sunny and seasonably warm day, near to slightly above 80 north and upper 80s to near 90 south, dropping into the upper 50s to low/mid 60s Saturday Night.

Broad high pressure moves more overhead on Saturday Night and through Sunday, which will persist fair weather and light winds to end the weekend with just some high clouds starting to fill in overhead. A sea breeze will develop once again with the light winds during the afternoon, with temps topping out in the 80s before the boundary moves across eastern areas. More cloud cover will result in a bit milder lows Sunday Night, generally 60s to near 70 by the coast and St. Johns River.

LONG TERM
(Monday through Thursday)
Issued at 313 AM EDT Fri May 10 2024

High pressure moves offshore Monday, with a much more unsettled pattern looking to take shape for most of this period. A frontal system approaches the area with a warm front passage on Monday, followed by the trailing cold front Tuesday and into Wednesday.
The boundary looks to stall almost directly over the CWA around the Wednesday/Thursday time frame, with several shortwaves moving across the area and maintaining chances for showers and t'storms before more of a "kicker" front approaches towards the end of the week. Temperatures start this period near to slightly below average with the unsettled weather, then towards near to slightly above average by Wednesday/Thursday.

MARINE
Issued at 313 AM EDT Fri May 10 2024

Offshore Southwest to West flow will remain at SCEC (Small Craft Exercise Caution) levels (15-20 knots) ahead of the cold frontal passage Today into this evening with the main marine hazard with strong to severe storms with damaging wind threat impacting the waters in several waves through this evening. Winds shift to the North at SCEC levels after midnight tonight behind the cold frontal passage and spread across the local waters. These winds become onshore/NE on Saturday and weaken to 10-15 knots as the weak high pressure ridge builds over the waters for the weekend with weak pressure gradient and No headlines expected with local sea breezes during the afternoon hours. The old frontal boundary lifts back to the North as a warm frontal boundary on Monday and stalls across the local waters on Tuesday as several waves of low pressure track along this feature. Increasing SE winds on Monday to possible Small Craft Advisory levels will shift to South and Southwest on Tuesday as the waves moving along the frontal boundary with a more unsettled pattern of showers and storms at times, with heavy rainfall and gusty wind threat at times early next week.

Rip Currents: Low to Moderate risk of rip currents expected Today through the weekend with surf/breakers around 2 feet, before onshore/SE flow increases on Monday with a potential for solid Moderate to High Risk of rip currents.
