For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf
Today: Initial impulse of convection along the stalled frontal boundary across inland SE GA early this morning will continue to drift eastward towards the coastal SE GA and this Atlantic waters through sunrise. Then expect a brief lull in convection before the high pressure center builds into the Carolinas and sends another surge of East to Northeast winds down the SE US coastline and into the region and this act as a catalyst along with diurnal heating that will allow for the East Coast sea breeze and frontal boundary to kick off scattered showers and storms over the NE FL Atlantic Coastal waters that will move onshore to the I-95 corridor and Atlantic Coastal Counties by the late morning hours, then track inland across the rest of NE FL through the afternoon hours where they will likely become more numerous by the time they reach the I-75 corridor due to the increased diurnal heating there. This set up will lead to a large range in Max temps from the mid/upper 70s for coastal SE GA and into the lower 80s for inland SE GA to the north of the cold frontal boundary, while more diurnal heating expected prior to the onset of convection across NE FL will lead to highs in the lower 80s for the Atlantic beaches to middle 80s for the I-95 and US 17 corridors, and into the upper 80s and around 90F for the rest of inland NE FL. The more intense heating across inland NE FL will lead to the potential for a few stronger storms with gusty winds and small hail. The slower movement for some of the storm activity will lead to locally heavy rainfall, but overall most of the rainfall will be welcome to many locations that haven't received any measurable rain in over 2 weeks. A surge of East to Northeast winds is expected as the high pressure pushes the frontal boundary southward reaching breezy levels at 15-20G25-30 mph along the Atlantic Coastal Counties and into the 10-15G20-25 mph range over inland areas.
Tonight: As the frontal boundary pushes south of the region and high pressure builds into the Carolinas, any lingering convection over inland areas during the evening hours should end by midnight, while the onshore flow may continue a slight chance of showers and a few thunderstorms over the Atlantic Coastal waters. Overall the region should see a decrease in cloudiness after midnight with winds diminishing over inland areas as lows fall into the 60s, while Coastal areas will only see lows around 70F.
SHORT TERM
(Tuesday through Wednesday night)
Issued at 239 AM EDT Mon Apr 28 2025
Surface high pressure off the mid-Atlantic coast gradually shifts southeastward to off the Carolinas coast by Wednesday. On Tuesday, some lingering moisture will support a few showers developing along the sea breezes as they shift inland Tuesday afternoon. Due to the easterly flow, best chances for rain will be west of I-75 where the sea breezes will likely merge late in the afternoon.
Drier air and subsidence will suppress convection for mid-week.
Temperatures return to around seasonable with highs in the upper 70s/low 80s along the coast to the mid/upper 80s inland. Overnight lows will generally be in the upper 50s to mid 60s.
LONG TERM
(Thursday through Sunday)
Issued at 239 AM EDT Mon Apr 28 2025
High pressure off the southeastern seaboard retreats into the Atlantic as a cold front enters the SE US Thursday night into Friday. A series of shortwaves aloft will parade across the region helping to enhance convection along and ahead of the frontal boundary. A few showers and storms will develop mainly in SE GA Friday into Friday night. The front shifts southward toward the FL/GA state border by Saturday morning and continues its trek southward into central FL Saturday night. Diurnal instability, sea breeze interactions, and left over convergence north of the front will result in isolated to scattered showers/storms on Saturday.
Temperatures return to above seasonable for the end of the week.

(12Z TAFS)
Issued at 735 AM EDT Mon Apr 28 2025
Convection around SSI will tend to decrease over the next 2-3 hours as the frontal boundary hanging over the southeast GA area shifts southwest to south but MVFR to IFR expected there. Occasional IFR vsby/cig in fog/stratus conditions early this morning at VQQ should end there soon. Additional convection mainly offshore waters will tend to stay there into the mid morning but a few showers are likely to form near the northeast FL coastal TAF sites by late morning and early aftn. Unsure if we will need any TEMPO group for coastal northeast FL TAFs but at this time looks like VCSH or even a VCTS is appropriate for now. For GNV TAF, we put in a TEMPO MVFR TSRA group from 18z-22z.
East winds increase to 10-15 knots for the coastal TAF sites and 10- 12 knots for inland TAF sites. Towards the end of the TAF period from 00-06Z, expecting winds over inland TAF sites to diminish as rainfall chances end, while the onshore flow will continue rainfall chances (VCSH) at SSI/SGJ through the end of the period.
MARINE
Issued at 239 AM EDT Mon Apr 28 2025
Frontal boundary has sagged southward into the NE FL coastal waters and awaits another surge of E-NE winds to 15-20 knots this afternoon and evening as high pressure builds north of the local waters and pushes the frontal boundary south of the region and will keep the SCEC headlines in place with the morning forecast package through tonight. High pressure ridge axis builds southward into the local waters this week with Easterly flow on Tuesday at 10-15 knots, then becoming Southeasterly on Wednesday and Thursday as the high pressure ridge builds further offshore. Longer range models still show next frontal boundary approaching the region on Friday with a shift in winds to South and Southwest, but still at below headline levels, then the weak frontal passage takes place early on Saturday before the next high pressure builds north of the region on Sunday with a return to East to Northeast winds and potential for the next SCEC headlines late in the weekend.
Rip Currents: Surge of E-NE winds at 15-20G25-30 mph later today as high pressure builds north of the region will increase surf/breakers into the 3-5 ft range by late this afternoon and evening and will continue the High Risk of Rips which will likely linger into Tuesday as onshore flow remains at 10-15G20 mph with surf/breakers in the 2-4 ft range.
