Aviation
[through 12z Wednesday]VFR conditions are expected to prevail
through the period with clear skies behind a cold front.

Northwest winds are expected to gust to around 15 knots from the
late morning hours through sunset.

Prev discussion [259 am edt]
Near term [through today]
A drier and cooler airmass will prevail across the region today
behind a cold front. Skies will be clear with afternoon high
temperatures ranging from the lower 70s across the northwest to the
upper 70s across the southeast big bend.

Short term [tonight through Thursday]
The upper level trough will continue to amplify tonight into
Wednesday before sliding off to the east setting up nearly zonal
flow on Thursday. At the surface, a large area of high pressure
centered over the southern plains will move east centering over the
local region on Thursday. It will remain dry with cooler than normal
temperatures continuing through the period. Highs will range from
the upper 60s to the lower 70s. Lows will be in the lower to mid 40s
inland (around 50 along the coast) tonight and around 40 (mid to
upper 40s along the coast) Wednesday night.

Long term [Thursday night through Tuesday]
Temperatures will briefly return to seasonal levels Friday Friday
night as low level flow becomes southerly ahead of the next deep
trough and accompanying cold front. This front will bring a chance
for scattered showers Saturday Saturday night along with below
normal temperatures to finish out the weekend and continue into
the first part of next week.

Marine
Northerly winds are expected to increase back to near small craft
advisory levels tonight in the wake of a secondary cold front.

Thereafter, conditions will gradually improve through the end of
the week.

Fire weather
Although a dry airmass will prevail for the next several days, red
flag conditions are not expected with rh values remaining above
critical levels.

Hydrology
Due to recent heavy rains, the shoal river at mossy head rose
quickly but crested just below flood stage. 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.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
