GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 249 Pm Est Thu Dec 13 2018
Synopsis..Atlantic high pressure across the eastern gulf of mexico slides off to the east as a strong low pressure center tracks along the gulf coast then through the southeastern states...trailing a cold front over the gulf of mexico. This front with a preceding squall line or two reaches the eastern gulf waters Friday then exits across florida to the atlantic Saturday. High pressure builds into the western gulf Sunday and tracks east...reaching the eastern seaboard midweek. Strong winds with gusts perhaps close to gale force with large waves and seas begin to impact the waters later tonight. Mariners should check the latest forecast when planning any trips through the weekend.

246 pm est Thu dec 13 2018

Slight risk of severe thunderstorms Friday...

Hazardous conditions are expected to impact marine waters and
beaches...

Discussion
Robust mid level low over tx this afternoon takes an easterly
track... As ridging east of fl moves away... Along the western gulf
coast Fri then over the southeastern states during sat. At the
surface - ridging over fl and the east gulf slides to the east as
the surface reflection of the tx mid level low drags a cold front
across the gulf. The front reaches the west-central and southwest
fl coastal waters Fri then slips across the state to the atlantic
sat.

Moisture and wind fields begin to increase over the gulf later
tonight ahead of the approaching system... Shift into the coastal
waters early fri... Then cross west-central fl Fri morning into the
afternoon and southwest fl afternoon and evening. These times are
first guess and will be adjusted over the next couple of forecast
cycle. A squall line or two is expected to form ahead of the
front with strong to severe thunderstorms that can produce
damaging wind gusts... Tornadoes or waterspouts... And locally heavy
rainfall with flooding. The most active weather will be moving
east across the state toward the atlantic late Fri night. Large
waves and swells will be generated in the western gulf that
translate onto area breaches for the weekend with a high risk of
rip currents expected.

For Sun - thu: the mid level low exits the southeastern coast early
in the period as ridging builds into the nation S mid-section from
mexico then slides east through wed. Surface high pressure settles
into the western gulf Sun then tracks to the eastern seaboard by
midweek. On Thu a mid level short wave trough low moves into the
southern plains with a surface low cold front forming on the western
gulf coast. The upper and surface ridging dominate for much of the
period with dry seasonable temperatures. Moisture increases enough
by Thu to support some showers and a few thunderstorms.

Aviation
13 18z TAF cycle.VFR conditions as bkn-ovc mid deck continues and
lowers with increasing low clouds. E and ese winds... Gusty at times
this afternoon... Back slightly and slacken over night then begin to
increase and become SE to sse aft 14-15z. Approaching cold front
with a sq ln will bring vcsh to northern terminals aft 14z... With
vcts at tpa aft 14 20z. Conditions are expected to deteriorate byd
this TAF cycle.

Marine
Increasing winds ahead of an approaching storm system will require
small craft advisories on some of the waters tonight... And spread to
the rest of the waters as the system moves into the coastal waters
fri with thunderstorms and possible waterspouts. The front crosses
the state Sat then moves out over the atlantic. This system is
generating large waves and swells in the western gulf that will
translate into the local waters for perhaps much of the weekend.

High pressure begins to build into the western gulf Sun then slides
to the eastern seaboard by midweek with winds veering and
diminishing.

Fire weather
Atmosphere continues very moist with no low humidity concerns. Storm
system coming in from the west will bring showers... Thunderstorms...

and locally heavy rainfall mainly Fri with some showers and a few
storms into sat.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
