GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 858 Pm Est Thu Jan 18 2018
Synopsis..Winds and seas will remain calm through the remainder of the week as high pressure dominates our weather pattern and northeast/east winds prevail. Another cold front approaches the area by the early part of next week and as high pressure builds to the north and increases the pressure gradient, headlines may be possible. The potential for sea fog will also exist ahead of this front as winds veer more southerly and dewpoints increase back into the 60s.

Another night of freezing temperatures in parts of west
central florida...

update...

it was a rather chilly afternoon across west central florida
as none of us were able to climb out of the 50s. With the
loss of daytime heating, temperatures will gradually fall
through the night but nowhere near as abrupt as last night.

Low temps remain a bit challenge overnight. While efficient
radiational cooling will take place, a few issues may
prohibit halt cooling... Forecast soundings continue to show
winds veering overnight with warmer, easterly winds at
approx 2000 feet potentially mixing to the surface and
limiting the cooling. Second, satellite observations through
the afternoon show high cirrus clouds streaming into the
area, generally south of the i-4 corridor. Some models have
struggled to pick up on this throughout the day and if these
clouds thicken, this will also limit radiational cooling
south of the nature coast. With that said, temperatures
have not been adjusted this evening, especially since
uncertainty exists to warrant a significant change...

a couple of other changes were made to the ongoing forecast,
however. First, sky cover was increased (to account for the
high cirrus). Additionally, current observational trends and
overnight guidance suggest slightly higher dewpoints - so
these were nudged higher. For this reason, frost was
introduced into the forecast for inland locations and
especially the nature coast.

Aviation...

prevailingVFR conditions through the TAF period with
varying winds out of the northeast to northwest. High
cirrus will stream across the region from the southwest with
the thickest clouds residing over our southern terminals.

Marine...

winds and seas will remain calm through the remainder of the
week as high pressure dominates our weather pattern and
northeast east winds prevail. Another cold front approaches
the area by the early part of next week and as high pressure
builds to the north and increases the pressure gradient,
headlines may be possible. The potential for sea fog will
also exist ahead of this front as winds veer more southerly
and dewpoints increase back into the 60s.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
