Short term today through Wednesday
Primary concern is onset and magnitude of light snow beginning this
afternoon. Near term hires models in good agreement with primary
model guidance that band of light snow should move into far NW ga
around noon to 1p today and slowly moving south toward the rest of
north and west ga during the afternoon. Since this system is more of
a post-frontal overrunning rather than an eastward-moving low
pressure system to our south, it's going to be difficult to see much
precipitation, especially considering the strong push of cold dry
air behind the front. That said, with sfc temps eventually going
well below freezing, it won't take much precip to cause impacts on
roads. Based on latest QPF and temperature guidance, our snow
amounts went up just a touch, but still mostly remain below 1.0
inch. Another change we saw in recent guidance was the development
of a secondary band of light snow over southern al into westcentral
ga during the evening hours. This band could produce up to 1 inch
just by itself as it pushes from the lagrange and surrounding areas
into the south atl metro.

By Wed morning, temps should have bottomed out while wind speeds
peak. At this time, wci values are in the single digits to around
zero over much of north and west ga and well below zero in the
mountains. Wind chill warning criteria may be met in a few spots in
the higher elevations but have kept this area as a separate segment
in the advisory for now.

Black ice may be an isolated problem Wednesday where snow amounts
are an inch or higher, but with such light amounts of liquid-
equivalent precip, strong winds, abundant sunshine and dry air, do
not believe there will be much to refreeze.

Long term Wednesday night through Monday
A deep trough will be moving off the east coast at the start of the
period with a transition to a northwest to west flow aloft. A very
dry air mass will spread over the forecast area and persist until
late in the weekend. Gfs ECMWF in general agreement of an increase
in moisture on Sunday as high pressure moves off the east coast and
low level winds become southerly. A strong short wave moving through
the upper ms valley late Sunday into Monday will push a cold front
through north and central ga on Monday. Pops will increase across
the area Sunday into Monday. A strip of low CAPE approaches the west
central counties on Monday and isolated thunder is not out of the
question... But for now have kept the mention of thunder out.

12z update...

initialVFR conditions then approaching strong cold front late
afternoon into evening with increasing chance of -sn (especially
for northern TAF sites). CIGS should decrease to MVFR after about
00z for near katl along with increasing -shsn chance - have made
predominant given increased chance confidence in amounts mainly
0.5-1 inch near katl. Less confident for other sites to east and
south so left prob30 groups accordingly. Should start
improving scattering after 06z. Expecting increased NW winds of
near 8-12 kts gusting 18 kts with higher mags for tomorrow.

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.
