Area Forecast Discussion
National Weather Service Peachtree City GA
158 PM EST Sun Feb 19 2017

.SHORT TERM /Tonight through Monday Night/...
Ridge of high pressure will dominate the weather pattern over the
state through the short term. Winds will shift to the east around
the surface high on Monday, drawing Atlantic moisture into the
region. As a result, after a sunny day Monday, clouds will increase
over the area Tuesday. There is enough low level moisture will
provide an opportunity for patchy fog to develop each morning
through Tuesday. Next system approaches the area just beyond the
short term period.

Warming trend expected through the short term, with lows generally
in the 40s and low 50s, and highs reaching the mid to upper 70s
Monday afternoon. Forecast temperatures are generally 2-3 degrees
from record values. Please see the Climate section below for
reference.

.LONG TERM /Tuesday through Sunday/...
Mainly only tweaks to the long term based on the latest guidance.

PREVIOUS DISCUSSION...
Models in good agreement holding a surface to upper level ridge over
the CWA through Tuesday afternoon. Another developing frontal
system moves out of the southern and central plains and into the
Southeastern U.S. Tuesday morning. This front brings increased
chances of showers to the CWA Tuesday afternoon through Wednesday.
The forecast models differ a bit on the strength and intensity of
this next system but they both show it weakening as it pushes
into GA. There is very little instability with it so staying with
showers and no mention of thunder. This weakening system keeps
increased moisture over the area through the end of the work week
so will keep slight chance to chance pops across the area through
then. Another short wave and associated cold front will move out
of the midwest and into the eastern US Friday. This system is
expected to have a little more instability with it so keeping in
the mention of isolated thunderstorms for Friday/Friday Night.
This second front appears to move east of the CWA Sat and clear
things out for Sat afternoon and Sun.
