Area Forecast Discussion
National Weather Service Peachtree City GA
316 PM EDT Mon Jun 26 2017

.SHORT TERM /Tonight through Tuesday Night/...
Much drier and cooler air mass remains has settled over the area as
high pressure dominates. Expect building cirrus overnight tonight
into Tuesday as a series of upper level impulses traverse an
approaching upper level trough. Even with the trough, little
convective development is expected due to the abnormally dry high
pressure at the surface. Have continued with slight chance pops over
the north Georgia mountains where orographic influence could supply
enough lift for some showers to develop. Additionally, have
continued slight chance pops over the far SE CWA where a convergence
zone will combine with diurnal heating to produce isolated
convection. Regardless, expect any activity to be sub-severe.

Have opted for a blend of guidance for temperatures through the
short term period.

.LONG TERM /Wednesday through Monday/...
No major changes to the long term. The quick return of tropical
air still looks on target for the latter half of this week.
Previous long term discussion follows...

LONG TERM /Tuesday Night through Sunday/...
A dry air mass is in place at the start of the period with a
surface ridge centered over the Appalachians. The ridge gradually
moves east...and by Thursday the return flow is bringing moisture
back into the state. Models continue to hint at a weak short wave
in the northern Gulf by the weekend...and also a front approaching
from the OH Valley toward the end of the period. In general we
remain in a tropical air mass from Thursday and beyond and chance
pops for most areas each day look reasonable.
