Marine Weather and Tides
Tyndall AFB, 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.

area forecast discussion
national weather service tallahassee fl
921 am edt Mon jun 18 2018

Update
No significant changes were made to today's forecast; minor
adjustments were made to chances of showers and thunderstorms and
temperatures based on latest observations and model trends.

Scattered showers and thunderstorms are still possible, mainly
this afternoon and early evening during peak instability times as
the sea breeze moves inland. Highs will reach the lower-mid 90s
inland and upper 80s along the gulf coast.

Prev discussion [327 am edt]
Near term [through today]
Upper level ridging was centered over the eastern us this morning.

The mean winds in the low mid levels of the atmosphere will be
light this afternoon so expect shower and thunderstorm development
to be focused along the seabreezes and influenced heavily by any
thunderstorm outflow that forms. Did note slightly drier air to
our west in mississippi and also off the eastern florida coast.

The drier air west of tallahassee albany, and weak northwest flow
in the low mid levels will keep precipitation chances lower in
these locations. Enhanced moisture, along with weak low-level
convergence along the easterly-flow seabreezes, will keep the
precipitation chances higher east of tallahassee albany.

A warm day is in store with the lower precipitation chances for the
central and western portions of the forecast area. Temps will climb
into the low to mid 90s in these areas. Slightly cooler conditions
(due to better precipitation chances) are anticipated in eastern
portions of the forecast area.

Short term [tonight through Wednesday]
Throughout the short term, a mid upper ridge will be meandering
across the southeast us. This ridge will act to suppress
convection somewhat Tuesday but not entirely. The eastern third
of the CWA has the higher chances for rainfall Tuesday. A surface
trough approaches the area Wednesday and the mid upper ridge
weakens somewhat with the approach of an upper trof into the
central southern plains. We could see an increase in rain chances
Wednesday with a little more moisture and instability especially
associated with the seabreeze. Highs each day will be in the lower
to middle 90s.

Long term [Wednesday night through Monday]
Upper ridge gets shunted southeast and weakens as the upper trof
digs southward and sweeps across the area through the weekend.

Ridging begins to build back over the southeast in the wake of the
upper trof early next week. Rain chances will be around
climatological normals for this time of year with good coverage
each afternoon due to the upper trof in the area and weakening
subsidence. Highs will remain in the lower to middle 90s.

Aviation [through 06z Tuesday]
Vfr conditions will prevail through the period. Scattered thunderstorms
will develop from 18z Monday through 00z Tuesday with the highest
probability from tlh aby and eastwards. MVFR ifr conditions are
likely in any thunderstorms.

Marine
Favorable marine conditions are anticipated this period featuring
low winds and seas. Isolated to widely scattered showers and
thunderstorms are anticipated just about each day. Locally higher
winds and seas possible in and around heavier convection and near
the coast with the daily seabreeze.

Fire weather
No fire concerns are anticipated for the next 7 days. However,
slightly warmer and drier conditions are anticipated over the next 2
days before rain chances climb by the middle of the upcoming week.

Hydrology
All area rivers are below flood stage with just a couple around
action stage. On average, 1-2 inches of rainfall is anticipated
over the next week. Widespread flooding is not anticipated but
some localized areas of flooding in urban and poor drainage areas
is possible.

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.
