735 pm edt Mon oct 23 2017

Aviation [through 00z Wednesday]
A cold front has moved through the region andVFR conditions are
expected through the forecast period. Breezy northwest winds up to
17 knots are expected Tuesday afternoon.

Prev discussion [312 pm edt]
Near term [through tonight]
Latest mesoanalysis as of 18z shows the cold front stretching
from apalachee bay northward across the fl big bend into south
central ga. Along and just east of the front, a band of showers
and isolated thunderstorms will continue moving eastward late this
afternoon, pushing east of our area tonight. Isolated strong wind
gusts cannot be ruled out across our southeastern areas as this
occurs, but ample cloud cover has suppressed instability and
prevented thunderstorms from strengthening so far today. A few
showers isolated storms will linger across the eastern fl big bend
during the early evening, but will likely end around sunset as
the cold front continues moving east southeast of our area. Much
cooler and drier air will move into our area overnight in the wake
of the front, with lows dropping into the 50s across our area by
Tuesday morning.

Short term [Tuesday through Wednesday night]
Slightly cooler airmass will follow the initial front on Tuesday.

However, afternoon highs will still likely reach the mid to upper
70s. Primary trough axis will dig into the deep south by late
Tuesday, sending the main push of colder air across the forecast
area. Expect lows on Wednesday and Thursday mornings to reach well
into the 40s. Highs on Wednesday are unlikely to reach 70 degrees.

Long term [Thursday through Monday]
Temperatures will briefly moderate on Thursday and Friday as a
shortwave ridge crosses the area. Thereafter, another deep trough
is expected to dig into the eastern states, bringing another
round of below normal temperatures for Sunday into early next
week. Scattered showers will be possible ahead of this front on
late Saturday into early Sunday.

Marine
Northwesterly winds are expected overnight in the wake of a cold
front with conditions dropping to exercise caution levels. Winds
will increase back to near small craft advisory levels Tuesday
night in the wake of a secondary front. Thereafter, conditions
will gradually improve through the end of the week.

Fire weather
A dry and cool airmass will move over the region on Tuesday in
the wake of a cold front. Daytime relative humidity values will
drop into the low to mid 30 percent range for much of this week,
though this will still be above red flag criteria.

Hydrology
The heaviest rain fell over the far western portion of the
forecast area overnight, with as much as 8 inches reported in
western walton county. This caused the shoal river at mossy head
to rise quickly above action stage. However, the river is expected
to crest below flood stage this evening. Elsewhere, modest rises
are expected on area rivers, but none are expected to reach flood
stage.

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.
