Area Forecast Discussion
National Weather Service Peachtree City GA
339 PM EDT Thu Jul 6 2017

.SHORT TERM /Tonight through Friday Night/...
An elongated trough will slowly drop south through the period. This
will mean persistent shower/thunderstorm activity, especially during
the afternoon/early evening hours along this boundary.

Today/Tonight: We will see north GA get the brunt of the
precipitation activity.  Thunderstorms may become strong to severe
with the main threats being gusty winds, frequent lightning and
heavy rainfall. Small hail can not be ruled out.  With ample
instability (3500 J/kg of MUCAPE, 1000 J/kg of DCAPE and marginal
LI) thanks to sufficient insolation and PWAT values around 1.75",
expect the ongoing activity to continue until sunset. Much of this
activity should dissipate after sunset. However, with enough forcing
aloft as the trough approaches, this may support on going scattered
shower/thunderstorms overnight, especially across northern GA with
better dynamics.

Friday:  As the aforementioned trough starts to cross from north to
south through the day, we expect to see better coverage across
metro Atlanta over to Athens by late morning with this activity
pushing south through late afternoon.  Much like the storm mode we
are witnessing today, we do not anticipate much organization to
these storms. However, it does seem like we might have a bit more
shear to work with as compared to the previous days. Some of these
storms could become strong to severe as instability will be present
with better upper level support. The extent of instability will also
depend on the amount of cloud cover, but all indications point to
enough insolation again tomorrow. The main threats will be gusty
winds, frequent lightning, small hail and heavy rain.

Friday Night: Shower/thunderstorm activity may take a bit to taper
off, even beyond sunset.  However, by midnight expect most of the
activity to have diminished or shifted south of the region.

High temperatures will be around normal, maybe a degree or two
above...mid 80s to around 90 across north GA to the mid 90s in
central GA.  Higher terrain will be a bit more pleasant sitting
around the low/mid 80s.

.LONG TERM /Saturday through Thursday/...
Primary concern in the long term period is again location and
likelihood of mainly diurnal convection. 12Z model cycle continues
to confirm large scale upper ridging in the western CONUS and
longwave troughing in the eastern CONUS. Wave with band of
somewhat stronger westerlies will dip into north Georgia tonight
thru Sunday then weaken and lift back north early next week. This
model cycle a tad more optimistic about some drier air moving into
far north GA Saturday night thru Monday. Should be able to drop
PoPs and sky cover as well as lower min temps a few degrees there.
Daytime highs will probably remain similar to what we've seen.
Rest of north and central Georgia should remain in moist airmass
with seasonal temperatures and typical coverage of diurnal
convection. For Tuesday through Thursday, entire area will return
to moist airmass with very weak flow aloft and diurnal convection
with heavy rain possible. Some signs that western CONUS upper
ridge will move into the central CONUS on Tuesday as well.

In the Atlantic basin, tropical depression 4 expected to remain
weak or weaken as it moves slowly WNW to areas north of the Lesser
Antilles by early next week. 12Z models, if anything, confirm
this trend.

.PREV DISCUSSION... /Issued 317 AM EDT Thu Jul 6 2017/

LONG TERM /Friday Night through Wednesday/...
A slow moving cold front approaches n GA Friday night and is
forecast to move to the N to central GA area on Saturday. Precip
potential should diminish Friday night but develop again on
Saturday...peaking in the afternoon for most areas.

Highest pops look to favor central GA on Sunday and Monday with
the front or surface trough stationary over the area.

With the pattern changing little...fairly typical summer pops
for showers and thunderstorms Tuesday and Wednesday with a moist
airmass over the forecast area.

Forecast temperatures are running within 1 to 3 degrees of normal.

.AVIATION...
18Z Update...
A mix of VFR and sub-VFR cigs will occur through the remainder of
the afternoon and early evening as thunderstorms are in the
vicinity. We have seen an increase in coverage of storms and this
trend should continue through late afternoon. Expect reduced
vsbys and gusty winds of 20-30kts associated with these
thunderstorms. Anticipate that most of this convection should
dwindle after sunset. The convective debris will clear with some
high clouds streaming through the overnight. West winds will
diminish. As the boundary starts to sag south, expect a bit more
coverage of shower/thunderstorms tomorrow across all TAF sites.

//ATL Confidence...18Z Update...
Medium to low on precip timing/coverage.
High on all else.
