Area Forecast Discussion
National Weather Service Peachtree City GA
1058 AM EDT Thu Aug 1 2019

.UPDATE...

With steadily increasing deep moisture over the forecast area, the
coverage of showers and thunderstorms is once again expected to
increase relative to the previous few days. Likely PoPs across far
north Georgia and high-end chance PoPs across central Georgia are
anticipated by mid-afternoon. High precipitable water coupled with
slow storm motion will contribute to the potential for some
isolated flash flooding concerns where heavy rain persists for a
prolonged amount of time. A few storms this afternoon and evening
could also be strong to severe and produce gusty winds and
frequent lightning in addition to the heavy rain. The forecast
remains on track through the morning, with only minor adjustments
made based on the latest guidance.

UPDATE...
Updated for aviation. Also removed mention of fog in most areas as
vis imagery shows little coverage to fog. Rest of fcst looks good.

SNELSON

PREV DISCUSSION... /Issued 432 AM EDT Thu Aug 1 2019/

SHORT TERM /Today through Friday/...

Pattern not expected to change much next 48 hours, still stuck in
the middle of two large upper ridges with plenty of moisture.
Another slight increase in coverage of convection this afternoon/
evening compared to last few days. PoPs in likely category over
north GA but decent coverage expected over middle GA as well. Same
story for Friday afternoon/evening but with likely PoPs over the
entire area.

As seen last two days, a few storms this afternoon/evening will
approach or briefly reach severe criteria with damaging winds and
frequent lightning. PW values also a bit higher today, approaching
80th percentile for this time of year, around 1.8-2.0 inches. This
high PW and weak mean winds will increase risk of flash flooding
today and Friday, though gridded FFG quite high, esp over middle GA
due to overall dry soil conditions from lack of rainfall last few
weeks.

SNELSON

LONG TERM /Friday Night through Wednesday/...

A broad upper level southeast trough will continue to dominate
the weather for GA. Also...a weak and diffuse boundary will linger
over the state. This combined with increasing tropical moisture
will support mainly chance pops through the long term. The pattern
will be mostly diurnal but showers and thunderstorms could last
well into the evening hours. A weak tropical disturbance over Cuba
and the Bahamas should slowly approach FL by Friday and then turn
gradually northeast over the weekend. The upper trough eventually
drifts a bit east toward the Atlantic Coast by mid week...putting
our area in a more west to northwest flow aloft. However...still
a chance for showers and thunderstorms.
