Aviation
[through 06z Friday]VFR conditions are expected to prevail
through the period with clear skies. Northerly winds are expected
to be 10 knots or less.

Prev discussion [638 pm est]
Near term [through tonight]
***key points***
* very cold temperatures are expected tonight, so people are
encouraged to take proper precautions. Remember to protect the 4
p's: people, pipes, pets, and plants.

* any residual moisture lingering across areas that received wintry
precipitation may experience refreezing overnight. Elevated
surfaces will be most at risk.

* be sure to dress properly each morning: wear layers and limit the
amount of exposed skin.

Discussion: strong cold air advection on northwest winds will
continue this afternoon and overnight under clear skies.

Temperatures will drop into the upper teens across SE al and
portions of SW ga that received snowfall that lingers into tonight.

Around 20 degrees is expected elsewhere away from the coast. What
may help from reaching those numbers is the winds will be around 5-
15 mph most of the night. This may help temperatures from not
totally reaching the forecast lows, but wind chills will be in the
lower teens to upper single digits. Nevertheless, upgraded to a hard
freeze warning overnight over inland areas and continuing the wind
chill advisory everywhere.

Short term [Thursday through Friday night]
While the story of the short term period will be the rise in
temperatures, another night of temperatures in the 20s are expected
Thursday night into Friday morning. Clear skies and calm winds with
high pressure building into the region will allow for maximum
radiational cooling across, yielding overnight lows in the low to
mid 20s. Be sure to continue to protect the 4 p's: people, plants,
pets, and pipes!
an appreciable warming trend will commence on Friday, along with
increasing moisture from the south as the aforementioned low level
ridge axis slides off to the east. An increase in southerly flow
around the periphery of the high coupled with a weak mid-level
impulse embedded within the southern region of the jet will yield an
increase in cloud cover over the weekend. Rain chances, however,
will remain scant until the beginning of the work week, when the
next upper level low ejects out of the rockies and across the
eastern half of the conus.

Long term [Saturday through Wednesday]
Dry conditions will give way to rain chances to start the work week,
as the aforementioned system sweeps into the region from the west.

Shower activity will will likely be confined along and ahead of the
trailing cold front, yielding another round of drier and cooler air
in it's wake. Expect afternoon highs to warm from the 60s on
Saturday to the upper 60s and 70s Sunday through the end of the
period. Overnight lows will generally remain in the 40s through much
of the period.

Marine
A small craft advisory remains in effect through Thursday morning
for all coastal waters. Strong northerly winds from 20 to 25 knots
with higher gusts will result in elevated seas. Winds and seas will
decrease on Thursday, and become light from Thursday night through
Saturday.

Fire weather
Although minimum relative humidity values will be near or below
critical levels across the region the next few days, other criteria
for red flag conditions are not expected to be reached.

Hydrology
Dry conditions are expected to persist through the weekend. The next
chance for rain will come on Monday, as showers are expected to
develop along an approaching cold front. Given the expected
progressive nature of this system, rainfall totals are not expected
to yield any flooding issues across the region.

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.
