Near term [through today]
It's been an interesting winter so far, and today is no exception.

***changes from previous forecast***
added more of a wintry mix of freezing rain and sleet along the
front edge of the precip before changing over to all snow as
temperatures fall. As a result, added small ice accumulation of a
couple hundredths across the northwest half of the area in addition
to snow amounts up to 1 inch. This will only make travel more
treacherous.

***key points***
greatest impacts are expected across southeastern alabama and
portions of southwest georgia. However, a small amount of freezing
rain extending down into the florida panhandle will result in some
icy conditions there as well. Bridges and overpasses will be
particularly at risk of seeing snow and ice accumulation.

*timing: greatest impacts lasting through around 11 am est.

Concerning wintry precipitation: the addition of more of a wintry
mix was based on upstream reports and hrrr soundings supporting
light freezing rain and sleet at the onset before changing over to
all snow. Hrrr derived p-type superimposed on the current radar
shows this as well. A band of moderate snow is expected across
southeast alabama and extending into southwest georgia before precip
comes to an end this morning. Will monitor reports closely for any
last minute upgrades to a winter storm warning, but overall the
message remains the same. Travel will be very hazardous in the
areas of freezing rain, sleet, and snow this morning with
temperatures falling well below freezing this morning and struggling
to rise above freezing this afternoon.

Short term [tonight through Friday]
***key points***
* very cold temperatures are expected Wednesday and Thursday
nights, 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 receive wintry
precipitation on Wednesday may experience refreezing from
Wednesday night into Thursday morning. Elevated surfaces will be
most at risk.

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

As the cold front moves farther southeast of our area tonight, dry
conditions will occur and cold air advection will persist under
north-northwesterly flow. As a result, temperatures will drop
into the lower 20s overnight across our area, with our
northwestern areas likely reaching the upper teens on Thursday
morning. Coldest locations will be in SE alabama, where some
residual light snow cover may help to reduce temperatures even
more. As winds remain around 10 mph, apparent temperatures will
drop to the 10-15 degree range across most of our area, with even
some single digit wind chills in our NW locations early Thursday
morning. As a result, wind chill advisories are in effect across
our area, with a hard freeze watch for all but immediate coastal
areas.

Temperatures will rebound nicely on Thursday under clear skies and
decreasing winds, but due to the very cold start, highs will only
reach the mid-upper 40s across our area. As high pressure settles
in to our area, temperatures will drop quickly again on Thursday
night under clear skies and light winds with lows reaching the
lower-mid 20s inland and upper 20s along the coast. As deep layer
ridging builds on Friday, highs will reach the 50s across our
area.

Long term [Friday night through Wednesday]
Deep layer ridging will continue to build from Friday night
through Sunday, leading to dry conditions and a warming trend
this weekend. Highs will reach the lower 60s on Saturday, and
range from the upper 60s to near 70 on Sunday. From Sunday night
into Monday, an upper level trough will move eastward across our
area along with a cold front at the surface. The combination of
strong forcing and increasing moisture will lead to a good chance
of rain Monday as the front moves eastward across our area. Dry
and slightly cooler conditions will return from Monday night
through midweek behind the front as high pressure builds back over
our area.

Aviation [through 06z Thursday]
Wintry tafs for most sites through the mid-morning hours with a
mix of precip at most places except vld, and transitioning to snow
at aby and dhn.VFR conditions are expected to return from west
to east through the day with clearing skies and gusty northwest
winds.

Marine
A small craft advisory remains in effect through Thursday morning
for all but eastern nearshore zones. Strong northerly winds from
20 to 25 knots with higher gusts will result in choppy seas.

Winds and seas will decrease on Thursday, and become light from
Friday through Saturday.

Fire weather
Conditions will be close to red flag this afternoon across portions
of the florida panhandle due to high ercs and northwest winds around
15 mph, but rh values are borderline near 28 percent, so will hold
off on issuing a red flag warning. After today, red flag conditions
are unlikely for the remainder of the week.

Hydrology
Light snow and mixed precipitation will fall this morning across
western and northern parts of our area, and then dry conditions
will persist through the weekend. As a result, no flooding is
anticipated and moderate to severe drought conditions will
persist.

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.

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.
