High pressure to the northwest Today, will build to the north
Tonight. With subsidence under ridging, and dry air in place a
mainly clear night is forecast.  The change in location of the high
will result in the flow coming more from the northeast overnight.
Due to this onshore flow, areas along the coast will be notably
warmer overnight, than locations further inland. Lows in the middle
50s along the coast, with lows in the mid 40s further inland are
expected.

.SHORT TERM...
(Thursday through Friday night)
Issued at 158 PM EDT Wed Apr 16 2025

Warm and dry conditions are expected Thursday and Friday as high
pressure moves to the northeast, promoting winds to shift onshore.
Easterly winds on Thursday will shift more southeasterly Friday,
which will allow `cooler` temperatures near the coast both days,
with highs in the mid to upper 70s. Inland highs will have a
chance to rise above normal with clear skies and calmer winds,
reaching the low to mid 80s Thursday, and mid to upper 80s on
Friday. Low dewpoints both days will keep heat indices from
getting too unpleasant. Onshore breeze overnight will allow for
more mild temperatures along the coast, with inland lows dipping
into the 50s.

&&

.LONG TERM...
(Saturday through next Wednesday)
Issued at 158 PM EDT Wed Apr 16 2025

Similar temperatures to Friday are forecast this weekend with
partly cloudy skies, although coastal locations will be heating
up into the low to mid 80s as winds remain from the southeast.

Rain potential returns on Monday and Tuesday as a front approaches
from the northwest and stalls over central Georgia. With daytime
temperatures reaching the mid to upper 80s and PWATs rising near
1-1.5", there is a chance for isolated thunderstorms Tuesday
afternoon over portions of inland southeast Georgia.

.AVIATION...
(18Z TAFS)
Issued at 116 PM EDT Wed Apr 16 2025

VFR conditions are expected this period.

&&

.MARINE...
Issued at 158 PM EDT Wed Apr 16 2025

A cold front will continue to move south of the area, as high
pressure builds to the northwest. This high will build more toward
the north Tonight, then northeast on Thursday. The high will remain
centered to the northeast Friday into Saturday, then to the east on
Sunday. A frontal system will affect the area early next week,
bringing a chance for showers and thunderstorms.

Rip Currents: Moderate through Thursday.

.FIRE WEATHER...
Issued at 158 PM EDT Wed Apr 16 2025

Critically low relative humidity values will continue for inland
locations on Thursday, near 20-25%, but winds will be a little bit
calmer as they shift easterly. Dispersion will be fair on Thursday,
with overall good values on Friday with some patchy high dispersion
over inland southeast Georgia and north central Florida as winds
increase and turn to southeasterly. The southeasterly winds will
help bring some moisture into the area, although minRH will stay
near 30-35% for inland locations Friday through the weekend.
