Area Forecast Discussion
National Weather Service Jacksonville FL
1050 PM EST Sun Jan 22 2017

.UPDATE...
Have added isolated thunderstorms over inland north FL for
later tonight based on recent radar trends and lightning data.

Prior discussion...
The broken line of strong to severe thunderstorms that affected
the region today has moved well out into the coastal waters. A
summary of storm reports will be forthcoming this evening.

We are still expecting a low chance of showers the rest of the
tonight as sfc troughing pivots around the main sfc low at an
impressive 983 mb over nrn GA and ern TN. This low will slowly
push eastward through Monday. Any remaining thunderstorms are
expected to push further out across the outer coastal waters over
the next hour. Pres gradient associated with the strong low will
continue to produce gusty winds of 25 to 35 mph tonight and
continue into Monday. Wrap around moisture will continue to
produce areas of low clouds through tonight as well.

&&

.AVIATION...Prevailing VFR expected tonight though there is a
small chance of MVFR cigs. A better chance of MVFR cigs for TAFS
for Monday...mainly after 14z/15z as wrap around moisture from
aforementioned sfc low moves through the region. Sfc winds
southwest to west at 15g30kt this evening should slowly decrease
later tonight. Winds become more prevailing from the west on
Monday 15-20g25kt.

.MARINE...No significant changes for the forecast except to
refresh wording on the weather portion.
