Aviation
[through 12z Friday]
+shra is east of the TAF sites and anything the next few hours
will just be light showers. Ifr to MVFR CIGS are in place but will
see improvements by mid to late morning with the clouds scattering
out. While gusts 18-20knots are possible this morning, winds will
be lower than yesterday.

Prev discussion [221 am est]
Near term [through today]
As of 2 am est the line of thunderstorms is almost out of the
region. Rain is starting to taper off in our westernmost counties
but many fl big bend and SW sc georgia counties will have rain until
the early morning hours.

In the upper levels a trough will be over the central and eastern
u.S. Today. At the surface a cold front will move through the region
early this morning. Cool dry air will move in behind the cold front.

Rain will move out by mid to late morning. Clouds will clear out
this afternoon. Highs will be in the 50s.

Short term [tonight through Saturday]
In the upper levels a trough will be over the central and eastern
u.S. At the surface high pressure will be over the region. Pops will
be near zero. Skies will be mostly sunny clear. Highs will be in the
50s. Lows will be near freezing in most locations tonight. Lows will
be in the upper 20s and lower 30s on tomorrow night.

Long term [Saturday night through Thursday]
In the upper levels a trough will be over the central and eastern
u.S. A shortwave will move through on Sunday. At the surface high
pressure will be over the region until the next system approaches
Monday night into Tuesday. The best chance for rain will be on
Tuesday. Highs will be in the 50s or 60s. Lows will be in the 30s.

Marine
After the gale warning expires at 4 am est, a small craft advisory
will be in effect until late morning. Winds will become
northwesterly early this morning as a cold front moves through.

Fire weather
Widespread rain that moved through overnight ahead of a cold front
will diminish today. While conditions will begin to dry out, rh
values will remain above critical thresholds and thus red flag
conditions are not forecast.

Hydrology
Rain will continue to exit the area this morning and then we'll see
a few dry days ahead. Widespread rainfall amounts of 1-2 inches have
fallen with isolated areas around 2.5 inches. This has resulted in
rises on area rivers with multiple rivers expected to rise into
action stage over the next few days.

Specifically, the shoal river at mossy head rose into action stage
and should crest just below minor flood. In addition, the chipola river
at altha is expected to reach minor flood over the next few days.

Meanwhile, the apalachicola river at blountstown will remain in minor
flood.

In regards to coastal flooding, with the strong winds near panama
city last night, tide gages indicated around 2-3 feet mhhw and given
the impact statements for those locations, likely saw minor coastal
flooding. While some locations around apalachee bay have elevated
water levels, the winds haven't quite been as strong and were in low
tide, however with high tide approaching in the next few hours, will
continue with the coastal flood advisory through mid morning.

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.
