Near term [through tonight]
As discussed this morning, showers and thunderstorms are developing
along and east of a trough axis deep layer moisture gradient from
near panama city northeast through tifton. Right along this dividing
line storms have the greatest potential to produce gusty winds as
some drier air gets entrained in the middle troposphere. Expect the
coverage of storms to increase through the afternoon, coming to an
end around or shortly after sunset. Patchy fog will develop
overnight and be most likely in locations receiving rain this
afternoon. Overnight lows will dip to around 70 degrees across the
region.

Short term [Friday through Saturday night]
A large area of deep layer high pressure will remain stagnant from
the great lakes through texas for much of the period, with a weak
upper level low meandering over the region between the
aforementioned high and hurricane maria in the atlantic. While
the low will linger across the area and boundary layer moisture
remains high, increasing mid level dry air will suppress most
convection across the region tomorrow. Any activity that does
manage to develop will be short lived, as updrafts are expected to
remain weak and activity will be unable to sustain itself. With
moisture remaining stagnant in the boundary layer and drier air
aloft, patchy fog is not out of the question Friday night.

Saturday, the weak mid- level low will tap into moisture preceding
hurricane maria, increasing mid- level moisture and rain chances
once again across the region. Pops will generally range from 30 to
40% across the northwest half of the cwa, with 40 to 60% across
the southeast half. Shower and storm activity will migrate
offshore Saturday night, with patchy fog possible across the
region - especially in areas that receive rainfall. Temperatures
will run near climatology through the period, with highs in the
upper 80s to near 90 and lows in the low 70s.

Long term [Sunday through Thursday]
A drying trend will ensue at the beginning of the long term period,
as the weak upper low mentioned in the short term period drifts
westward and eventually dampens out. This will allow for high
pressure and drier conditions to build into the region Sunday
through much of the work week. There are some early signals of the
ridge breaking down beyond the long term period (day 9 to 10), as
global models hint at a vigorous upper low and associated cold
front approaching the region, which *could* bring more fall like
conditions to the region. Until then, warm and muggy conditions
are expected, with highs generally in the mid to upper 80s and
lows in the lower 70s.

Aviation [through 18z Friday]
Vfr conditions will prevail outside of thunderstorms this afternoon.

Scattered storms have begun to develop across the region and are
most likely at ecp, tlh, and vld. Late this evening, storms should
come to an end and between 06-10z MVFR ifr visibilities will set in
across the region. Restrictions will clear by 13z tomorrow for all
terminals.

Marine
Easterly winds and seas will increase to potentially cautionary
levels this weekend as hurricane maria moves up the gulf stream and
increases the pressure gradient between it and the large area of
high pressure across much of the southeastern united states. Winds
of 15 to 20 knots will be common out of the east Friday evening
through Sunday evening, with seas generally in the 2 to 3 foot
range. Winds and seas will calm next week.

Fire weather
No concerns.

Hydrology
Aside from locally heavy thunderstorms that could yield a quick 1 to
2 inches of rain, rainfall amounts generally less than 1 inch is
expected each day through Sunday morning. Are river levels continue
to trend downward this afternoon, with this trend expected to
continue.

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.
