.NEAR TERM...
(Today and Tonight)
Issued at 1218 AM EDT Sat Aug 9 2025

A localized flood threat will continue today and tonight as a
combination of a tropical air mass with PWATs over 2 inches, old
frontal boundary and continued East to Southeast steering flow off
the Atlantic will produce numerous to widespread showers with
embedded thunderstorm activity with waves of heavy rainfall,
mainly along the Atlantic Coastal Counties/I-95 corridor during
the overnight and morning hours, then shifting inland during the
afternoon/evening hours. The random location of some of these
heavier rainfall bands and intense downpours in storm activity
makes it hard to place a Flood Watch for any specific location,
but the urban areas will generally have the higher risk of any
localized flash flooding potential through tonight. Higher
rainfall chances and abundant cloud cover will keep max temps
below normal with highs generally in the mid/upper 80s, except for
some portions of inland NE FL south of the I-10 corridor where
Max Temps will top out closer to 90F this afternoon before
rainfall reaches some of these farther inland locations. Overnight
lows will remain closer to normal values in the lower/middle 70s
inland and upper 70s along the Atlantic Coastal areas. Likely too
much cloud cover for any significant inland fog, but some patchy
fog and stratus is expected across inland SE GA and the Suwannee
Valley towards sunrise today and again early Sunday morning.
Overall rainfall totals will generally be around one half to one
inch over inland areas, with 1-2 inch totals along the Atlantic
Coastal areas, and with low level convergence aimed more at the SE
GA coastal areas this period, likely will see some localized 2-4
inch amounts from JAX northward to Brunswick, GA through Sunday
morning as the steering flow becomes more East to Southeast
through tonight.

.SHORT TERM...
(Sunday through Monday night)
Issued at 1218 AM EDT Sat Aug 9 2025

Wet pattern continues into Monday as the frontal boundary
gradually diffuses over north FL. Coastal troughing tightens as
high pressure wedges down the eastern seaboard slightly increasing
east-southeasterly flow. Elevated PWATs (2"-2.4") will support
periods of heavy rainfall for showers and storms that develop
along the boundary interactions between the stalled frontal
boundary and the inland moving Atlantic sea breeze. A few strong
to marginally severe thunderstorms will be possible mainly along
the sea breeze merger near I-75 corridor. Saturated soils from the
recent multi-day rainfall events will make it easier for areas to
flood and trees to uproot. Mostly cloudy skies and daily
convection will keep highs below seasonable in the mid 80s for SE
GA to low 90s for NE FL. Overnight lows will be in the 70s.

.LONG TERM...
(Tuesday through Friday)
Issued at 1218 AM EDT Sat Aug 9 2025

Frontal boundary over the area dissipates on Tuesday as Atlantic
high pressure ridging builds back into the region for the week.
Deep layer moisture gradually decreases as ridging increases
bringing a return to a more typical diurnal sea breeze pattern.
Convective coverage becomes scattered to numerous developing along
the inland moving sea breezes each afternoon into evening.
Developing southerly flow will shift the sea breeze merger and
stronger storm potential to the US 301 corridor. With the decrease
in storm coverage and ridging increasing aloft, temperatures will
rise to above seasonable with highs in the low/mid 90s area-wide
by midweek. Peak heat indices will rise into the 100s and
potentially reach Heat Advisory criteria.

.AVIATION...
(06Z TAFS)
Issued at 1218 AM EDT Sat Aug 9 2025

High rainfall chances this period in the onshore flow will require
multiple TEMPO groups for MVFR CIGS/VSBYS at the coastal TAF sites
of SSI/SGJ/CRG/JAX, while the high rainfall chances at VQQ/GNV
will mainly be during the afternoon hours, so will time this TSRA
activity with 6 hour PROB30 groups during the main window from
18-24Z at VQQ and 19-01Z at GNV. Some low chances for low level
stratus at SSI around sunrise with lower MVFR CIGS but not
expecting the lower LIFR conds that were experienced on Friday
morning. Easterly winds at the coastal TAF sites will reach 10-12
knots today, but inland TAF sites will remain below 10 knots
expect for any gusty winds to 25-30 knots in TSRA activity at
times.

.MARINE...
Issued at 1218 AM EDT Sat Aug 9 2025

A nearly stationary frontal boundary will remain across the local
waters through the weekend. An area of low pressure may develop
along this boundary off the Carolinas this weekend. This low would
move then northeast into the open Atlantic late in the weekend, as
troughing extends southwest over area waters. High pressure will
build to the northeast next week, with southeast flow continuing
at below headline levels.

Rip Currents: Solid Moderate Rip Current Risk this weekend with
surf/breakers at least 2-3 ft through Sunday, some possible uptick
into the 3-4 ft range on Sunday with potential for a borderline
high risk as some larger swells reach the local beaches in E-SE
flow.
