Area Forecast Discussion
National Weather Service Jacksonville FL
202 AM EDT Tue Jun 15 2021

.AVIATION...
[Through 06Z Wednesday]

VFR conditions will persist through into tomorrow with chances for
early AM showers and thunderstorms developing in areas near and
south of GNV. Showers and storms are expected to develop today
with a chance for the formation of isolated severe storms. Winds
will be out of the SW today with wind speeds reaching upwards of
about 10-14 knots with gusts of up to 20 knots. Storms are
expected to dissipate in the evening hours.

&&

.PREV DISCUSSION [931 PM EDT]...

.Short Term.../through Wednesday/...

Dissipating frontal boundary stretched east to west across area near
the GA/FL line this afternoon. Areas along and south of this
boundary will experience the greatest chance for showers and storms
Today, due to better moisture. Storms will be possible across SE GA
this afternoon north of the boundary, but the best chance for
activity will be near the coast in SE GA due to convergence along
the east coast sea breeze. The storms are expected to be slow
movers, so in addition to the potential for a few strong storms,
heavy rainfall is also expected with localized flooding possible.
The activity will decrease in coverage toward midnight.

Another trough will move into the southeastern US Tonight into
Tuesday morning, and enter SE GA in the afternoon. With a prevailing
flow from the southwest the east coast sea breeze will be pinned
pretty close to the coast. Best chance for convection across NE FL
as west coast sea breeze moves inland, acting as a source of
convergence in the diurnally unstable airmass. Organized convection
could stretch up the east coast of SE GA as well. The convective
activity will dissipate Tuesday evening.

For Wednesday, trough will sink a little further to the south.
Closer to the FL/GA line. Drier air will move into SE GA behind the
boundary, helping to limit best chance for convection over NE FL and
coastal SE GA.

Lows will be near to a little above normal this period. Highs will
trend above normal across SE GA Tuesday and Wednesday, but near to a
little lower closer to central FL, due to cooling from cloud and
shower coverage.

.Long Term.../Wednesday night through Monday/...

Boundary will linger over the area into Thursday as it dissipates.
High pressure will build to the east Friday into Saturday, with
troughing to the north. An area of low pressure will track to the
west then northwest of the area Sunday into Monday. Precipitation
chances will be more limited into Saturday, with chances increasing
late in the weekend into next week.

Lows will trend near normal this period. Highs will be above normal
over SE GA Thursday and Friday, and near to a little below over NE
FL. Over the weekend into early next week, highs will be near to a
little below normal.

.Marine...

A dissipating frontal boundary will linger over the area into
Tonight. Another trough will move into region from the north
Tuesday, then stall over area Wednesday into Thursday. A weak ridge
will build to the east Friday into Saturday. Low pressure will track
to the west then northwest of the region Sunday into Monday.

Rip Currents: SE GA: Low through Tuesday
              NE FL: Low through Tuesday
