Short term tonight through Tuesday night
Attention continues to be on the winter weather potential at the
end of the short term period. Latest model runs are advertising
slightly better moisture, and that, combined with cold thermal
profiles and partial thicknesses, will allow for a mainly an all
snow event. So models are indicating some better lift in the
dendritic growth zone, especially late Tuesday night and into
Wednesday morning over portions of western georgia and the south
metro middle georgia area, which could locally enhance
accumulations. In general, the models have an overall consensus
that this could happen, but with a lack of consistency run-to-run,
have opted to hedge amounts upward, but trend towards the more
conservative side. This is especially the case with the snow grids
for areas south of lagrange to macon to warrenton. The models are
also in agreement in depressing snowfall amounts in the
gainesville area due to downsloping. At this time, have advertised
less than half an inch accumulations in this area instead of the
near zero accumulations, but will need to monitor how subsequent
model runs sort this out.

Timing... Onset timing has sped up even from the overnight solutions,
with pops increasing in far northwest georgia from slight chance mid
morning to likely by 1 pm. Although the atlanta area could see some
flurries in the afternoon, the better chances will be in the early
evening hours through the wee morning hours.

Amounts... At this time, have gone with around 1 to 1.5 inches for
the higher elevations of north georgia, 0.75-1 inch for areas
generally north of a line from rome to ellijay, to blairsville, and
under 0.5 inches for areas south. At this time, have a tenth of an
inch advertised for as far south as americus (do not have any
accumulations for our far southeast corner counties). A winter
weather advisory has been issued for far north georgia and the north
and west metro atlanta area, with counties parsed out to best
reflect onset timing. At this time, although accumulations are
similar on the west side of the state (down to lagrange columbus)
confidence is much lower in these amounts for middle central
georgia. As a result, these areas have not yet been included in any
advisory, and instead a special weather statement has been issued
for them.

Other hazards... Taking a back seat to the snow potential is the wind
chill threat. Expect bitterly cold temperatures to impact the area
in the wake of the snow as extremely cold air settles over the area.

Temperatures Wednesday morning will be sub-zero or the single digits
in the far north, and in the teens across the metro atlanta area and
southwestward toward lagrange. Have opted to end the winter weather
advisory at 12z Wednesday to best capture both the snow and the wind
chill threat without having to issue multiple products. That being
said, it may be necessary to go ahead and issue a separate wind
chill advisory with tomorrow's afternoon package.


Long term Wednesday through Monday
Have kept a slight chance of lingering light snow over the
southeastern counties Wednesday morning. Previous long term
discussion follows...

long term Wednesday through Sunday ...

at the start of the period a long wave trough will be moving across
the southeast states. Very dry air will be spreading over the area
in the wake of a cold front. Models are consistent in pushing the
front to the edge of our forecast area by 12z Wednesday... However if
things turn out a bit slower there could be a period of
precipitation for our extreme east central counties Wednesday
morning and it would most likely be frozen or mixed. Moisture
looks like it is drying up as the front moves south so for now
have kept Wednesday morning dry. Expect very cold temperatures
Wednesday and Wednesday night and some gusty winds during the day.

After that... There is a gradual air mass modification as the flow
turns more west to southwest going into Saturday. By Sunday
another strong front will be crossing the ms river. Have
introduced pops mainly north and west for that day as moisture
gets pulled into the southeast states.


06z 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 for near
katl along with prob30 for -sn in the 00-06z window. Expecting
increased NW winds of near 8-12 kts gusting 18 kts. Timing a bit
later for other sites east and south, but should start
improving scattering after 06z. Any sn accumulations still mainly
light but cannot rule out up to 1 inch total.

Atl confidence... 06z update...

medium on timing of -sn chances.

High on all else.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
