Wintry January 8-9, 2018 Ice threat

KCAE's latest about this threat.

There remains some timing differences among the operational models
regarding this system but there seems to be a consensus on the
best chances of precipitation occurring in the Monday/Mon night
time frame so will continue to highlight the highest pops during
that time frame. Warm advection will begin on Sunday and
continue into Sunday night with the best moisture advection and
transport arriving through the day Monday with a strong
southerly 850mb jet around 40 to 50 knots. Thermal profiles are
such that precipitation begin briefly late Sunday night into
Monday morning as light snow or a snow/rain mix with wetbulb
temperatures below zero but will quickly transition to all rain.
Instability forecasts for Monday into Monday night suggest
little to no thunderstorm threat.
 
Latest from FFC about next week's potential ice storm threat in the Northern Georgia - Metro Atlanta area...

.LONG TERM /Friday through Wednesday/...
The main change to the extended forecast was Sunday night into early
Monday. The potential for wintry precip has increased.

High pressure will remain in control of the sensible weather through
the remainder of the week. The high center begins to shift offshore
later Saturday as a low pressure and front begin to move into the
mid Mississippi River Valley. By Sunday night, a wedge has formed
across NE portions of the forecast area. The wedge may end up
creating a wintry precip situation Sunday night into early Monday.
The cold temps at the surface within the wedge combined with the
warmer temps aloft will create the potential for freezing rain.

However, this is still 5 days out and the wintry precip potential
will be highly dependent upon the strength/position of the wedge.
The forecast will likely change.
