Area Forecast Discussion
National Weather Service Peachtree City GA
743 PM EDT Sat Jul 8 2017

.SHORT TERM /Tonight through Sunday Night/...
Current radar loop shows
showers and isolated Thunderstorms developing across the CWA this
afternoon. The main line of storms associated with the frontal
boundary is located NE to SW just north of the ATL area. For today
and Sunday afternoon the models are showing decent cape values in
the 2000 to 3000 J/kg with some shear noted as well. The better
instability moves south tomorrow along with the frontal boundary and
the associated storms. Expect some storms to become strong to severe
mainly north today and central Sun as the frontal boundary sinks
into south Ga through Monday. The main threats with any storms
through the short term will be gusty winds, frequent lightning,
small hail and heavy rain. Temperatures will remain near normal
through the period.

01

LONG TERM /Monday through Saturday/...
No major changes to the extended forecast needed.

Old frontal boundary will continue across portions of central
Georgia through the early part of next week. Even though the
boundary should be very weak and a trough by this time, a
convergence zone will remain. In addition, a shear axis aloft will
remain situated just near the boundary.

The slightly drier airmass across northern GA, north of the
boundary, should begin to erode late Monday or early Tuesday.
Typical summertime high humidities and hot temperatures will be the
rule. Thunderstorms will have plenty of fuel to work with and are
expected each afternoon and evening through the week.

Heat Indices will begin to creep up near 100 degrees by the middle
to late part of next week. Values may approach Heat Advisory
criteria across the SE portion of the outlook area beginning
Thursday.

.AVIATION...
00Z Update...
Overall weakening trend in the showers and thunderstorms over the
last hour or so. Have a TEMPO going for all sites except CSG thru
01-02z. Thereafter could see a few lingering showers before
clearing takes place. VFR conditions /aside from brief
thunderstorms/ are expected for a good majority of the evening and overnight
hours. Some patchy fog and isolated MVFR/IFR cigs are not
completely out of the question around sunrise given the humid
airmass...however confidence is too low to mention in the TAFs. A
frontal boundary should keep northern sites dry tomorrow...with a
PROB30 for TSRA covering CSG and MCN where the more unstable air
will reside. Winds still on the west side...though could briefly
flirt with slight NE around sunrise...but speeds should remain
well below 10kts.

//ATL Confidence...00Z Update...
Low on MVFR/IFR cig and fog potential.
High on all other elements.
