GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 239 Pm Edt Sun Aug 20 2017
Synopsis..A weak tropical wave will move over southern florida and into the eastern gulf of mexico later this evening into Monday. High pressure near bermuda ridges west over the area through the period. A series of waves on the south side of the ridge will move through the area producing scattered showers and storms through mid week. Rain chances increase on Wednesday and Thursday with numerous showers and storms expected. With high pressure to our north, a predominant easterly wind flow can be expected, but remaining 15 knots or less. So, outside of increased winds and seas as well as dangerous lightning in the vicinity of storms, no other marine impacts are expected.

241 pm edt Sun aug 20 2017

Near term through Monday
Another hot august day was observed across the region with
temperatures in the low to mid 90s. Only widely scattered showers
and storms have developed thus far this afternoon due to the
subsidence aloft and the slow progression of the east coast sea
breeze. Expect scattered to numerous showers and storms to develop
across the interior in the moisture tongue that exists from west
of st. Simons to the suwannee valley. A few strong storms with
gusty winds and small hail are possible. Scattered showers storms
will remain along the suwannee valley towards i-75 in the evening,
dissipating a few hours after sunset. As a trough approaches the
region tonight, shower chances will increase along the coast
overnight. Overnight lows will be in the 70s.

Upper level low over the south central gulf of mexico will shift
to the western gulf on Monday. An +pv anomaly associated with an
inverted trough wave was located from south central florida
northeastward into the western atlantic. This feature shows up
well on satellite, with significant cloud across southern and
central florida, and to the east of the region this afternoon. The
trough will slide north to northwestward tonight and Monday,
moving to the northeast florida coastline by Monday morning. A
strong upper level ridge across the western atlantic will build
across georgia and the southeast on Monday. A vort MAX associated
with the inverted trough over south central florida this afternoon
will move over northeast florida on Monday, and this will bring
deep moisture to the area, with precipitable water values above 2
inches. In addition, increasing cloud cover and rainfall chances
are expected along the coast late tonight into Monday morning.

Scattered showers and storms will then move inland through the day
as the wave axis shifts across the interior. Mostly cloudy skies
are expected across the southeastern half of the region Monday
morning, with clouds spreading inland as the trough moves to the
northwest. The best viewing locations for the eclipse on Monday
are northwest of alma and possibly along the coast in northeast
florida to the east of i-95 as the wave axis pushes across the
interior and a weak east coast sea breeze moves inland. Otherwise,
mostly cloudy skies will prevail through the day with scattered
showers and storms. Temperatures are forecast to be lower on
Monday due to cloud cover and scattered showers storms, with highs
in the upper 80s to lower 90s.

Short term Monday night through Tuesday night
Monday night... There will some drier air with precipitable water
values 1.30 to 1.60 inches working its way into north central
florida early Monday evening, in the wake of exiting trof axis
that moves into the gulf of mexico. However, moisture rich
atmosphere will exist between just south of i-10 corridor to just
north of georgia highway 82. Between this defined area and mainly
along and west of highway 301 some residual and ongoing convection
is most anticipated during the evening hours, then lifting
northward mainly north of the fl ga border during the late evening
through a couple hours past midnight, before everything abating
during the pre-dawn hours.

Tuesday and Tuesday night... Tuesday will feature a drier day
particularly south of i-10. Upper level ridge centered across the
southeast, and onshore flow continues as surface high pressure
moves further north across the mid atlantic. 30-40% pops are
across the region where there will be lingering shortwave energy
may remain with remnant weak surface trof just north of the
altamaha river basin. The thunderstorm chances should diminish
pretty rapidly Tuesday night with the loss of heating and upper
ridging extending from the offshore atlantic through the region
into the NE gulf of mexico.

Long term Tuesday night through Saturday
A cold front will approach the altamaha river basin Wednesday
morning and reside near the fl ga midday with pre-frontal trof
near i-10 during the afternoon. Strong heating and convergence
into a prefrontal trough supports thunderstorms mainly in the
afternoon. Consensus models and superblend have pops 30 to 50
percent. The thunderstorm chance will continue Wednesday night and
Thursday with the front in the area. It looks to be drier with
the front just off the coast Friday and Saturday, but confidence
is low with the front lingering not far to the east. Best chances
of rain will mainly be over NE florida particularly over the
eastern sections. A more consolidated tropical low may eventually
form along the remnant boundary across the east-central fl coast
Friday morning and shift east then NE over the open atlantic late
Friday through Saturday. Temperatures should remain above normal
ahead of the front through Wednesday. Expect maximum heat index
readings 100 to 105 Wednesday afternoon. The GFS and ECMWF mos
support near normal temperatures Thursday through Saturday.

Aviation
An isolated shower moved over kcrg around 18z, and an isolated
storm moved north of kjax along the east coast sea breeze.

Showers storms will develop and push inland this afternoon. Best
chance for shower storms later this afternoon will be at kvqq and
kgnv. East to southeast winds 5-10 knots will prevail this
afternoon. Mid high clouds will increase overnight as a trough
moves towards the region, and showers are possible along the coast
late overnight into Monday morning. Have vcsh from late tonight
through the end of the TAF period with increasing cloud cover.

Marine
Surface ridge axis will continue to shift north of the area
resulting in an easterly flow. The surface ridge will remain
northeast of the region through Tuesday. A frontal boundary will
then shift into the southeast by the middle of the week and the
ridge will shift back to the south.

Rip currents: low risk today, and low to moderate risk of rip
currents on Monday.
