Area Forecast Discussion
National Weather Service Jacksonville FL
918 PM EDT Tue Oct 17 2017

.UPDATE...

It is feeling much more fall-like across the region this evening.
There will be a large range in min temps overnight. Clear skies
and nearly calm winds will set the stage for well below normal
temps across inland southeast Georgia and the Suwannee valley
area of northeast Florida. In fact, areas from Alma northward will
see temperatures drop down into the mid to upper 40s overnight.
Windy onshore winds overnight at the northeast Florida beaches
will keep temps there closer to 70 degrees. Otherwise near normal
overnight temps are expected elsewhere. Most areas will remain dry
overnight but a weak inverted trough southeast of Flagler Beach
will move towards the coast and bring a chance for scattered
showers and isolated thunderstorms to coastal areas primarily
south of St Augustine. Locally heavy rainfall will be possible
with this activity late tonight across southern portions of
Flagler County.

&&

.AVIATION...

Challenging forecast on ceiling heights at the northeast Florida
terminals overnight. JAX, CRG, VQQ, and GNV are right on the
northern edge of the clearing line where ceilings have already
started to improve to VFR levels. There is still a chance however
that MVFR ceilings could move back in overnight. There is a much
better chance at SGJ for MVFR ceilings to continue overnight and
through the day on Tuesday.

Windy conditions will continue at the two coastal TAF sites (SSI &
SGJ) overnight and through the day on Tuesday. Inland TAF sites
will see northeast winds increase and become gusty again on
Tuesday. VFR conditions will continue at SSI where mostly clear
skies will prevail.

&&

.MARINE...

Small craft advisories remain in place for all adjacent southeast
Georgia and northeast Florida waters. Strong northeast winds will
continue overnight and through the day on Wednesday. Winds will
be sustained around 25 knots with occasional gusts to gale force
expected. Combined seas will remain in the 8 to 12 ft range with
occasionally higher seas up to 14 feet possible.

Rip Currents: High risk will continue through much of the week due
to strong northeast winds and rough surf.

&&

.Coastal Impacts...

Breaker heights up to 5 to 7 feet are expected at the northeast
Florida beaches through Wednesday and a High Surf Advisory is in
effect. A coastal flood advisory is also in effect for minor
flooding along the coast and along the St Johns River and its
tributaries during times of high tide. Some minor beach erosion
will also be possible along the northeast Florida coastline.
