GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 323 Pm Edt Fri Jun 23 2017
Synopsis.. No major marine hazards are expected through early next week. High pressure will continue to dominate our area - producing a southeasterly flow with winds taking on a south and west component during the afternoon/evening hours as the seabreeze forms and pushes inland. While greatest rain chances will remain inland, typical summertime boating precautions should still be exercised as any Thunderstorm can produce gusty winds and locally higher waves. By early into the middle of next work week, a cold front will push south and stall across our area and shift winds to more of a northeasterly direction.

Short term (tonight through Saturday)
For the short term... As the remnants of cindy pulls off to
the northeast, high pressure will continue to dominate the
area with the subtropical ridge axis stretched across
central florida and upper- level synoptic energy staying
well to our north. This pattern will maintain a prevailing
southeasterly flow through the period. Afternoon seabreeze
circulation will shift winds to the south, then southwest
this afternoon as well as tomorrow afternoon. Models
continue to indicate atmosphere moistening from south to
north through the day which will raise pw back to at or
above 2 inches. This moisture, coupled with daytime surface
heating and convergence along the eastward progressing
seabreeze boundary, will allow initiation of showers and
thunderstorms... But will be focused south of i-4 corridor.

Based on yesterday's diurnal temperature trend and current
observations, have opted to keep high temperatures
relatively untouched from previous forecast with temps in
the upper 80s near the coast and low 90s inland.

With the overall synoptic pattern remaining
very similar on Saturday, the main difference will be the
aforementioned moisture which will allow more widespread
rain chances for areas inland not yet stabilized by the
seabreeze. Both tonight and Saturday will see showers and
storms dissipating by 9pm.

Long term (Saturday night through Friday)
For the long term period, a very typical summer time
pattern will continue over the region. Upper level ridging
extends from bermuda west-southwest over the florida
peninsula. This pattern will hold until the beginning of
next week when the ridge sinks south as troughing digs into
the southeast u.S. By Thursday, the trough moves into the
western atlantic and ridging lifts back to the north over
florida and the southeast u.S. On the surface, subtropical
high pressure near bermuda ridges west-southwest over the
florida peninsula and into the northeast gulf of mexico.

This will keep a general east- southeast wind flow over the
region through the weekend and into early next week. The
high weakens and moves slightly eastward on Monday as a weak
frontal boundary shifts south over the peninsula. The front
will stall over southern florida by Wednesday as high
pressure settles back into the southeast u.S. Temperatures
will remain near seasonal averages with upper 80's during
the day and overnight lows in the mid 70's.

Aviation
Vfr conditions should prevail today with possible MVFR and
localized ifr conditions due to shra tsra across the
southern terminals fmy, rsw, pgd and no significant changes
have been made to tafs for the 18z issuance. Currently,
widespread shallow top CU field is evident on visible
satellite across the peninsula with some taller clouds
starting to appear over southern terminals near along the
sea breeze. Wind shift has already occurred at coastal
terminals with winds out of the southwest to west.

Marine
No major marine hazards are expected through early next
week. High pressure will continue to dominate our area - producing a
southeasterly flow with winds taking on a south and west component
during the afternoon evening hours as the seabreeze forms and pushes
inland. While greatest rain chances will remain inland, typical
summertime boating precautions should still be exercised as any
thunderstorm can produce gusty winds and locally higher waves. By
early into the middle of next work week, a cold front will push south
and stall across our area and shift winds to more of a northeasterly
direction.

Fire weather
Winds out of the southeast at 5-8 knots will shift to the southwest
with afternoon seabreeze passage with the only exception being highlands
and polk counties. Winds will become light and variable overnight with
poor dispersion. Rh is expected to remain above critical values
throughout the period. Isolated to scattered afternoon
evening thunderstorms are possible with convection focused south of
i-4 on Friday and more widespread but lower chances
Saturday.
