A frontal boundary will move just to the south this morning, and
become located in a southwest to northeast oriented inverted
trough this afternoon. This boundary will sink a little further
south Tonight, as high pressure builds to the north. Precipitation
chances will be greatest over NE FL, closer to the frontal zone.
The gradient between the high and trough will be elevated Today,
resulting in a surge of winds down the coast Today and Tonight. The
strongest winds will be north of St Augustine. At this time, not
anticipating gusts to reach wind advisory criteria, but could come
close.
Temperatures will be below normal Today, and near normal Tonight.

.SHORT TERM...
(Tuesday through Wednesday night)
Issued at 101 AM EDT Mon Sep 8 2025
The frontal zone will stretch from southwest of the area, across
central FL, then extending to the east of the area through Wednesday
night, while high pressure remains centered to the north.
Precipitation chances will continue to be greatest over NE FL.

.LONG TERM...
(Thursday through Sunday)
Issued at 101 AM EDT Mon Sep 8 2025
The frontal zone will push further south Thursday into Friday, as
high pressure to the north builds more toward the northeast.
Thursday and Friday will largely be dry inland, with greatest
precipitation chances focused toward the NE FL coastal counties.
The high to the northeast will weaken over the weekend, with an
another inverted trough developing over the western Atlantic. Inland
areas will remain largely dry over the weekend, with greatest
precipitation chances near the NE FL coast due to moist onshore
flow. Elevated coastal winds expected Friday and Saturday.
Temperatures will continue below normal this period.

.AVIATION...
(12Z TAFS)
Issued at 740 AM EDT Mon Sep 8 2025
A cold front is moving into the area today from the north, and is
past SSI at 1130z, and will be moving through JAX metro about
12z-14z. Increasing chances of showers and low cigs are expected
at times, mainly in the MVFR range. We can`t rule out an IFR cig
from near JAX north to SSI but felt not high enough to include at
this time. Current IFR cigs over inland southeast GA from Waycross
north may try to drift south but dissipate slowly later this
morning. Occasional showers and potential t-storms will be later
this morning and continue into the afternoon.
The front will bring a surge of gusty northeasterly winds today with
sustained winds peaking around 15-20 knots with gusts up to 30 knots
at coastal airfields this afternoon. Some of the low cigs may
break this afternoon for a while but likely move back in later
tonight with a chance of showers overnight.

.MARINE...
Issued at 101 AM EDT Mon Sep 8 2025
The area will be between high pressure to the north, and an inverted
trough over the western Atlantic early this week. The gradient
between these two features will result in a surge of winds extending
down the coastal waters. The gradient will relax mid week as the
high and trough weaken. The high will strengthen to the north
northeast late in the week, with troughing to the southeast. Once
again the gradient between these features will will result in
elevated winds.
Rip currents: High Risk of Rip Currents through Tuesday.

.HYDROLOGY...
Issued at 101 AM EDT Mon Sep 8 2025
The surge of winds down the coast Today into Tuesday could result in
coastal flooding at the coast, and along the St Johns river and its
tributaries, especially around times of high tide, as the tidal
water becomes trapped. Therefore, a coastal Flood Advisory
has been posted.
After a break Wednesday and Thursday, another surge of winds will
move down the coastal waters Friday into Saturday, once again
producing potential for coastal flooding.
