Marine Weather and Tides
Port St. Joe, FL

Version 3.4
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.

Aviation [through 18z Thursday]
Vfr conditions will prevail for the most part this period.

Scattered thunderstorms will develop in the vicinity of tlh and
vld this afternoon, but coverage is not expected to be high enough
to including a prevailing threat. A brief threat for thunderstorms
will occur on the inland moving sea breeze front this afternoon
near ecp.

Prev discussion [952 am edt]
Near term [through today]
An upper level ridge remains parked over the area with a surface
trough extending from the north carolina coast southwestward to
the florida big bend. The upper ridge will generally suppress
convective coverage below seasonal levels today. The exception
will be over the big bend and adjacent south central georgia where
the trough will combine with the sea breeze and outflow boundaries
to produce near climo pops of 40-55%. Look for mid 90s for most
areas this afternoon.

Short term [tonight through Friday]
The upper level ridge that has been keeping dry weather in place
over the region will begin to break down tonight as an upper
level trough and cold front swings through the central united
states. The forcing will remain well north of the region, but with
a weakening ridge of high pressure, this should help increase the
coverage of showers and thunderstorms on Thursday and Friday
afternoon in the southwest flow.

Long term [Friday night through Wednesday]
For the weekend, warmer and drier conditions are anticipated as
the ridge of high pressure builds back over the region. Looks
like the lowest chance for rain in the period will be Saturday as
drier air moves in from the west. By next week rain chances return
to normal as better moisture returns to the area from the
southeast.

Marine
Light winds will keep seas low through Thursday. Winds increase to
around 15 knots ahead of a weak cold front on Friday. 1 to 3 feet
seas on Wednesday Thursday will increase to 2 to 4 feet as
southwesterly winds increase increase Friday. Winds and seas
decrease by the end of the weekend.

Fire weather
No hazardous fire weather conditions are expected over the next few
days.

Hydrology
Near to below normal rain chances the next several days will keep
hydrology concerns at a minimum through at least the weekend.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @nwstallahassee.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
