Area Forecast Discussion
National Weather Service Peachtree City GA
230 PM EST Thu Jan 18 2018


.SHORT TERM /Tonight through Friday Night/...

Short term period will be dominated by dry weather as a surface high
in the ArkLaTex region continues to slide east towards the area. As
we get into the overnight hours of Friday, cloud cover will start to
increase as an upper level system moves northeast towards the area,
but not expecting any precipitation with this system.

A slight rise in temperatures is in store for Friday with highs in
the 40s and 50s in north GA with mid 50s further south, just a
degree to two below average. Low temps tonight are running about 10-
15 degrees below average with temps in the teens in the north with
20s elsewhere. The lows for Saturday morning are slightly warmer in
the 20s and lower 30s, although still just slightly below average.

With continued cold temps overnight and residual moisture/ice on the
roads, a special weather statement was issued earlier today for the
potential for continued hazardous travel through Friday morning.

.LONG TERM /Saturday through Thursday/...

Not too many changes to the extended forecast grids. Medium range
models continue to trend a bit slower with the early week system.
Generally delayed onset of POPs until daytime Monday and lingered
some likely POPs into Monday night and slight chance/low chance POPs
across the south and east into daytime Tuesday. Although instability
remains marginal, there appears to be just enough available to
include a slight chance of thunder Monday/Monday night.

Models also continue to bring the upper wave across the region
Saturday dry with none generating any measurable QPF amounts.

Temperatures start out a bit above seasonal normals, but spend the
majority of the period right around normal.
