.UPDATE...Cold front stretching from Nw Ga to Se Al will
weaken tonight as an upper ridge begins to build in from the south.
A cluster of showers and storms out just ahead of it will not make
any further progress to the southeast as a result. A few isolated
showers are still possible across the far Nw zones generally north
and west of line from Douglas to Alma.
The smoke plume from the West Mims Wildfire will move north tonight
affecting areas around Racepond...Folkston...St George... and
possibly as far north as Waycross. Visibilites across these areas
will be reduced to 1 to 3 miles but may be locally less then 1 mile
near and just north of the wildfire.
00z Jax sounding indicated the PW increased to 1.55. This increase
in moisture may lead to patchy low clouds and fog especially towards
the gulf coast and possibly the Atlantic waters. The SREF continues
to show high probabilites of dense fog towards the gulf and have put
in areas of late night fog for the western areas of the Suwannee
.AVIATION...Patchy low clouds and fog possible later tonight
with best chances at GNV between 09Z-13Z. Confidence is low on
extent of it although have carried previous fcst of MVFR cigs.
Prevailing VFR cigs expected most everywhere else although
monitoring IFR cigs currently at SSI which may require an upcoming
.MARINE...Data buoy obs indicate winds are SSE 15 to 20 knots
across much of the waters so have expanded the exercise caution for
all of the waters. The trend will be for winds to veer and gradually
decrease later tonight.
Rip Currents: Low risk expected through Friday.
