Update
Minor changes to bring temperatures current with the diurnal
trend as well as sky cover. A few sprinkles in the easterly
flow across portions of southwest ga and the eastern fl big
bend where there is a slight chance of showers today.

Marine
All of the waters are under a small craft advisory for winds over
20 knots or seas over 6 feet, or a combination of both. Occasional
seas around 8 feet beyond 20 nautical miles. Winds and seas will
be right at advisory levels through tonight so will keep the
advisory going until 8 am et on Saturday. Mostly dry weather
will prevail.

Prev discussion [644 am edt]
Near term [through today]
In the upper levels a ridge is centered over the southeast today. At
the surface high pressure is centered over the mid-atlantic with
easterly flow over the region. Pops will be low today, less than 10
percent in most locations as dry air remains in place. Skies will be
mostly sunny and temps will be lower today with highs in the mid to
upper 80s.

Short term [tonight through Sunday night]
Deep layer ridding remains in place over much of the eastern us with
surface high pressure building in as well. Even with a trough
moving in from the west on Sunday, the ridge and surface high
pressure remain in control of the weather. Locally, this means
easterly flow at the surface which will only bring in enough
moisture for a few mid level clouds. Otherwise, very dry air and a
strong subsidence inversion should limit any shower and
thunderstorm development. Highs Sat Sun will be in the upper 80s
with lows in the mid 60s up north to upper 60s lower 70s to the
south.

Long term [Monday through Friday]
Although the upper ridge does flatten starting on Monday, it
still have a firm hold over the southern states and the gulf.

Surface high pressure remains elongated from the atlantic
stretching southwestward. A front will be moving down from the nw
and because of the ridging, will stall to the north of our SE al
and SW ga counties. The inversion remains strong at least until
Wednesday, where there are some slight chance pops up north with
the front. The only other impact of the front would be a slight
increase in cloud cover each afternoon tue-thu. Once the front
dissipates, the ridge starts to build north again, with dry
weather continuing for Friday.

Highs will be in the low to mid 90s through the week with lows in
the upper 60s lower 70s.

Aviation
[through 12z Saturday]
vfr conditions expected this TAF cycle. High clouds are present this
morning with low clouds to the east. Easterly winds will be gusty
today with gusts up to 20 kt possible.

Fire weather
A dry air mass will be in place today but relative humidity will
stay above the critical threshold. Red flag conditions are not
expected. Winds will be gusty. High dispersions above 75 are likely
today.

Hydrology
Little to no rain is expected in the next 7 days and therefore,
there are no flooding concerns.

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.
