What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 358 Am Edt Wed May 23 2018
Synopsis..Atlantic high pressure ridging westward along latitude 30 north maintains southeast flow across the waters for the next few days...with winds 15 knots or less with seas 4 feet or less through the end of the week except higher in the vicinity of Thunderstorms. An area of low pressure may move into the gulf during the upcoming weekend and result in higher winds and seas. All mariners should continue to Monitor the progress of this system in the coming days.

357 am edt Wed may 23 2018

Short term (today-Thursday)
Slight modification today as a digging trough over the
eastern u.S has allowed winds above 50h over the peninsula
to shift to the west. W v imagery indicates this has caused
the core of the deep tropical plume of moisture to
temporarily shift east of the state with some slightly drier
air aloft advecting over the region. Increased subsidence
overnight and the drier air aloft has allowed skies to clear
across much of the forecast area. Deep moisture persists
below 50h with pcpw value on 23 00z tbw sounding still a
very respectable 1.87 inches. So for today, skies will begin
mostly sunny which will allow significantly stronger
insolation than the area has seen over the past week with
high temperatures generally in the upper 80s and possibly
around 90. Atmosphere remains quite unstable, and the
stronger insolation will increase convective instability
which will help create stronger updraft potential. Negative
factor will be weak boundary layer flow which will decrease
low level convergence. Scattered to numerous showers and
thunderstorms will develop this afternoon... With highest
pops over southwest florida in region of best deep layer
moisture and boundary interactions. Unlike previous days,
the stronger storms will be capable of wind gusts of 40 to
50 mph and can't rule out small hail as 50t hover around
-9c... Although the hail threat is quite low.

Thursday will be a transition day as the core of the deep
layer moisture begins to shift back over the area... And
another plume of deep tropical moisture poised over the west
caribbean begins to advect north toward the florida
straits. A bit more cloud cover expected on Thursday which
may hold MAX temps to the mid 80s... With upper 80s across
the nature coast. However lower than normal confidence on
max temps for Thursday given cloud cover could be delayed
which would lead to temps back in the upper 80s to around
90. Regardless... Increasing deep layer moisture and
conditionally unstable atmosphere will lead to numerous
showers and isolated thunderstorms across all of west
central and southwest florida with locally heavy rain again
possible.

The alafia river remains above flood stage, although it is
expected to fall below flood stage this morning. The manatee
river, little manatee river, and horse creek have all
receded below flood stage. However, very wet conditions are
expected through the weekend. Extremely wet antecedent
conditions are now in place... And any additional heavy
rainfall through the weekend may cause these rivers to rise
back above flood stage. The myakka river, which is much
slower to respond, has also been steadily rising and
additional rain could cause the myakka to rise above flood
stage. All individuals living along rivers creeks across
west central and southwest florida should closely monitor
conditions and be prepared to protect life and property due
to the threat of river flooding over the next several
days... With the greatest threat expected over the weekend
and into early next week.

Long term (Friday - Tuesday)
The main concern through the long term forecast period
continues to be the potential for heavy rainfall across the
region. A developing area of low pressure in the western
caribbean will move into the southern gulf of mexico this
weekend. The national hurricane center is currently giving
this system a 50% chance of development in the next 5 days.

Regardless of development, the real concern with this system
will be the heavy rainfall and flooding potential given the
increasingly saturated ground across the area. Exact
rainfall amounts would ultimately be determined by the track
this system were to take. Much uncertainty exists at the
moment however between model guidance with respect to the
placement, track and strength of this feature. Nevertheless
the one thing that seems certain is that with deep tropical
moisture in place across the area... Widespread showers and
storms will be likely nearly everyday. Unfortunately, for
those with memorial day weekend plans, it looks like the
weather is going to have a significant impact on them.

With all of the rain across the region for the last week
now, soils are getting very saturated at this point and
rivers are starting to run high (some already in flood
stage). Additional heavy rainfall is not a welcome scenario
for many spots, and hence we will continue to closely
monitor the evolution of this disturbance for this upcoming
weekend. Flood watches may be needed for portions of the
area in the coming days. Temperatures are forecast to run
below normal on Friday and into the weekend due to the
likelihood of abundant clouds and frequent showers.

For early next week, global models continue to show
cyclonic flow over the region with continued deep moisture
in place across florida, so the threat for additional
rainfall looks to remain even after this low pressure system
moves north of the region.

Aviation
PredominatelyVFR conditions will prevail today. LCL MVFR
cigs may develop during the late morning early afternoon
020-030. Scattered to numerous showers and isolated
thunderstorms will develop this afternoon with LCL MVFR cigs
and ifr vsbys.

Marine
Winds and seas are expected to remain below advisory levels
through the end of the week. Winds and seas may increase
above advisory levels over the weekend depending on any
development of an area of low pressure expected to move over
the gulf of mexico. Showers and thunderstorms will be
possible over the waters through the remainder of the week
and over the weekend. The stronger storms will be capable of
producing strong gusty winds, locally rough seas, and heavy
rain.

Fire weather
No fire weather hazards are expected for the next several
days as relative humidity values are expected to remain well
above critical levels.
