Synopsis -
a weak cold front will slowly drift southward into the forecast waters today through tonight. The front will linger over the area Sunday into Monday and then dissipate. Northeast to east winds will develop late tonight and continue through remainder of the weekend. In addition, there will be an increased chance of Thunderstorms over area waters through Sunday. As the front dissipates early next week, a ridge of high pressure builds to the south which will return south winds over the local waters.
Gulf stream -

NEAR TERM
(Today through Tonight)
Issued at 335 AM EDT Sat Jul 27 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
Weak surface high pressure at about 1017 mb is over north central FL and a weak backdoor front and trough are located over the southeast states. Both features will drift southward today toward the region while the airmass remains plenty moist, with the JAX sounding measuring PWAT at 2.18 inches last night. There may be some pockets of drier air across the north part of the area, but overall still looks like mainly numerous showers and storms today, developing along differential heating boundaries, sea breezes, and outflow boundaries. There may be widespread showers and storms across the Suwannee Valley down to near highway 301 this afternoon and early evening based on HRRR and HRRR model guidance. Main threats continue to be localized flooding from heavy rainfall, frequent lightning, and gusts to about 40-50 mph.
The steering flow continues to be very slow to the southeast but will be erratic at times. WPC has again highlighted a marginal risk of excessive rainfall due to the high moisture and instability today. Highs will push to lower 90s, but heat indices likely falling short of heat advisory with indices topping out to about 107 or so.
Tonight, we have indicated scattered to numerous showers and storms in the 6-8 pm time frame, but lowering to chance or less after midnight. Did adjust the NBM POPs late tonight thinking there will be lingering isolated, generally weak convection past 1-2 AM given the frontal boundary and pre=frontal trough moving into parts of southeast GA along with weak forcing in the mid levels. Lows tonight will be in the lower to mid 70s. Some patchy fog will be possible as well given light boundary layer winds.
SHORT TERM
(Sunday through Monday night)
Issued at 335 AM EDT Sat Jul 27 2024
Weak backdoor cold front across the FL/GA border will continue to decay into late Monday. Drier air building southward down the eastern seaboard north of the frontal boundary now looks to remain mostly offshore and could lower convective coverage across coastal SE GA on Sunday. Otherwise, scattered to numerous showers and storms develop along the sea breezes each afternoon into evening. With weak ENE flow, the Atlantic sea breeze becomes dominant with the sea breeze merger expected along the I-75 corridor. Slow, erratic storm motion combined with deep/tropical moisture in the atmosphere with PWATs over 2 inches will continue the heavy rainfall/localized flood threat area-wide across NE FL/SE GA.
Strongest storms will be along the sea breeze and outflow boundary collisions. Convection should fade each night by midnight. Highs will be in the upper 80s along the coast and low 90s inland.
Overnight lows will be in the 70s.
LONG TERM
(Tuesday through Friday)
Issued at 335 AM EDT Sat Jul 27 2024
Atlantic high pressure ridging attempts to build back in across FL mid-week next week resulting in weak steering flow. Moisture lingers across the area supporting scattered to numerous showers and storms developing along the sea breezes each day. With weak flow, the sea breeze merger will likely be along the US 301 corridor with locally heavy rainfall remaining the main threat.
Highs will start to climb toward the mid-90s later in the week.
Heat indices could reach advisory criteria (108 F) by Wednesday and potentially continue into the end of the week.
AVIATION
(12Z TAFS)
Issued at 748 AM EDT Sat Jul 27 2024
VFR conditions this morning with some upper level clouds with some cumulus developing this late morning as sea breezes start to push inland. Another active afternoon and evening for showers and storms mainly in the 19z-23z time frame, but lingering showers and storms likely around VQQ and GNV from 23z-03z. Have included TEMPO groups for most of the northeast FL sites, except for SGJ with PROB30 group due to lower confidence, and only a VCTS for SSI. MVFR and IFR with gusty winds expected in the TSRA. Showers and storms will start to abate this mid to late evening for VQQ and GNV. VFR conditions will generally persist during the overnight hours with some potential patchy fog developing near GNV and VQQ between 09z and 11z.
MARINE
Issued at 335 AM EDT Sat Jul 27 2024
Not much change in the marine forecast through the weekend, with just a slight bump in the east-northeast winds on Sunday as the backdoor front moves into the region. Seas generally look to be 2-3 ft through early Sunday with a dominant east- southeast wind- sea at 8-9 seconds. A bump up in the seas expected Sunday night but will gradually come back down to 2-3 ft by Monday night/Tuesday morning. Main weather concern will be the threat for a few more thunderstorms expected over area waters through Sunday. The nearly stationary front will probably dissipate by Monday, with weak sfc ridging building south of the Tuesday into Wednesday. Winds will remain light during the latter time at 10-15 kt at most.
Rip Currents: A moderate risk of rip currents was shown for today and Sunday and may be more prevalent within a few hours of low tide, with surf up to 2-3ft or 2 foot. Some weak east swells still noted about 12-13 seconds about half a foot. Little change for Sunday, but wind flow ill be more directly onshore.
