Aviation
[through 06z Saturday]
vfr conditions through the period with unlimited vsby and cigs.

Winds will be from the northwest around 10 knots or less.

Prev discussion [802 pm edt]
Near term [through today]
Continued dry weather with low temperatures remaining several
degrees below normal.

Some haze is possible this afternoon, especially east of the
flint and apalachicola rivers, due to prescribed burns. However,
there is sufficient mixing and wind such that it should not
reduce visibility significantly in any one location, compared
to yesterday.

A deep, dry northwest flow continues tonight. Clear skies will
prevail and winds will gradually diminish. Do not expect winds to
go completely calm, as a pressure gradient is maintained, but
subsiding to below 10 mph. Low temperatures will continue below
average, and have went a few degrees below the guidance, which
remains biased warm. Expect lows in the upper 30s to low 40s,
except mid to upper 40s closer to the gulf coast.

Short term [tonight through Saturday]
A very pleasant stretch of weather with moderating temperatures.

A mid-level ridge will gradually center over the mississippi
valley with an increasingly anticyclonic flow aloft building
high pressure at the surface. Subsidence will maintain a dry
column, with only some diurnal, fair weather clouds. No rain
during this period. Temperatures moderate during this period,
but still slightly below normal, owing more to chilly nights.

There is some uncertainty with high temperatures closer to
the gulf coast on Saturday, where a seabreeze may develop.

Long term [Saturday night through Thursday]
Dry thru this weekend with increasing precip chances thereafter.

The flow will gradually veer to the southwest Saturday night as a
broad long wave trough extends from the great plains into hudson's
bay. This pattern favors increasing clouds by late Sunday and
Monday. A stronger shortwave impulse will amplify the trough as it
rounds the base from the great plains toward florida early next
week. Wpc takes low pressure across north georgia by Tue morning
with a cold front on our door step at that time. This still favors
greater moisture and lift remaining just northwest of the area,
where the extended cips analogs keep heavier precip. Dry weather
through Sunday night with chances for precip increasing on Monday,
and persisting thru Tuesday night, especially north of i-10. There
is also a slight chance of thunder. A return to dry weather for
Wednesday and Thursday. Temperatures slightly above average
thru Tuesday, then slightly below average thereafter.

Marine
Conditions will be near advisory levels this evening and early
tonight in a brisk northwest flow. Small craft should exercise
caution. Winds and seas will slowly subside tonight into early
Friday. From late Friday into through Monday tranquil boating
conditions are expected, with winds less than 15 knots and seas
around or below 2 feet.

Fire weather
Red flag warnings will continue through this evening across much
of north florida. While rhs will remain critically dry and ercs
above 28 into the weekend, 20 foot winds will remain below 15
mph, precluding red flag conditions. Fog is not expected over the
next couple of days.

Hydrology
No rain is expected at least until Monday night. Even then, less
than half an inch of rain is forecast. Flooding is not expected.

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.
