.LONG TERM /Sunday Night through Friday/...

Primary concern in the extended forecast period continues to be the
wintry precipitation Tuesday. Still significant differences in the
medium-range models concerning mainly the amounts of precipitation
and the timing/duration of the mixing/change-over from liquid to
frozen precipitation. GFS and Canadian models continue to be faster
and noticeably lower in QPF than the ECMWF. This appears to be due
to the stronger, slower and more southerly track of the short wave in
the European solution. I have stuck with a model blend for now
(namely the NBM for most parameters and WPC QPF) with precipitation
type driven by a non-diurnal temperature trend during the day
Tuesday. This yields a potential for advisory-level or higher
snowfall amounts across the higher elevations of the far north.
Otherwise, only trace amounts are generated across north Georgia,
including into the northern and western metro Atlanta area. No
accumulations expected across central Georgia. Confidence that we
will see some kind of rain/snow mix across much of north Georgia is
fairly high, confidence on accumulations remains low at this time.
Cold and dry air moves across the forecast area from west to east by
late in the day with only lingering light rain in eastern portions of
the forecast area into the early evening. Wouldn`t be surprised to
see a few areas with a light rain/snow mix into central Georgia late
in the afternoon/early in the evening, but no accumulations across
that area.

I loved his write ups, but he actually moved to to the Fox6 blog. He hasn’t been on the abc blog for a few years now. All I ever see on the ABC blog now is spann, Bill Murray and Brian Peters.

That blog was better when you had Coleman and JB Elliot on it. Loved that blog

I doubt places outside of the mountains will get over 1" of snow. Some places may get near 2" but overall, it's not going to be a big snow maker. The bigger concern will be the rapidly falling temps. and the roads freezing up. Icy conditions are likely across the area's that did get precip.
