PREV DISCUSSION... /Issued 637 AM EST Mon Dec 11 2017/

SHORT TERM /Today through Tuesday/...

Cool and dry conditions will continue through the short term. Weak
high pressure over the state will give way to a dry cold front
expected to move through the area Tuesday. For now we are still only
expecting increased cloud cover with this frontal passage but the
models continue to show deeper moisture increasing across north GA
with every run. The models still keep the better moisture well north
of the region but will continue to keep a close eye on how this next
system develops over the next 24 hours. The good news with this
frontal passage is it moves through the state during the day time
hours Tuesday so if we do get any precip from it...it will be mainly
in the form of rain.

As for temps they will stay on the cool side with highs in the 40s
and 50s and lows mainly in the 30s.

LONG TERM /Tuesday Night through Sunday/...

No significant changes through the extended forecast period from
previous forecast trends. Medium-range models continue to be in
fairly good agreement through the period. Two mainly dry short waves
and associated cold fronts sweep through the region during the
workweek. Cold start to the period Tuesday night/Wednesday behind
the first system. Models indicate temperatures should rebound
quickly heading into the end of the workweek ahead of the next system
Friday. Marginal moisture available with this late week system, and
mainly confined to the southern and eastern portions of the forecast
area.

Much more vigorous system moves in at the end of the period. Much
warmer and more moist air mass sweeps into the region with this
system bringing much better chances for precipitation and minimizing
any chances for wintry precipitation types.
