.UPDATE...
A quiet but chilly night is in store for the area. Temperatures
have already fallen near or below freezing for many locales with
the warmest spots currently in the mid to upper 30s. Patchy black
ice will again be possible overnight in areas where melting snow
cover continues to provide wet roads.

SHORT TERM /Tonight through Monday Night/...

Continued quiet weather this forecast period as a dry airmass
predominates. Will need to keep an eye on a weak frontal system
and short wave approaching late Monday night with increasing
moisture for far n GA. At this time will continue to leave out
precip chances as significant deep moisture remains to the n.

Another night with temperatures below 32 for much of n GA.
Have included a Special Weather Statement for Patchy Black Ice
tonight around the area of snow melt today.

Forecast low temperatures are running 4-9 degrees below normal
tonight and near normal Monday Night. Forecast high temperatures
are running slightly below normal on Monday.

Overall confidence is high.

LONG TERM /Tuesday through Sunday/...

Looking like a tranquil extended period for the most part. Current
forecast handles late period system well and no changes are
planned.

Medium range models remain in very good agreement through the
extended forecast period, especially with respect to the large scale
pattern. Some subtle differences with strength and timing of the
various smaller scale features. Larger scale pattern remains fairly
static through the period with ridging dominating the western half of
the country and troughing over the east. This keeps the forecast area
in a cool pattern, however generally just keeps temperatures closer
to seasonal normals than we have seen through the fall across the
region. A couple of decent short waves sweep through the large
eastern trough through the upcoming workweek. The first around
Tuesday and the second Friday. Both give us a good shot of CAA on the
back side, but both also appear to be seriously lacking enough
moisture to generate any POPs right now. Upper pattern flattens
enough by next weekend to allow for some moisture return from the
gulf ahead of the next wave approaching over the weekend.
