Area Forecast Discussion...UPDATED
National Weather Service Peachtree City GA
153 AM EDT Sat Jul 1 2017

.UPDATE...
Near term forecast in good shape. PoPs if anything are too high
but will be updating those in next hour. 00Z guidance not showing
any surprises. Much less tropical-like today. Convection should
be getting started much later than previous two days.

.PREV DISCUSSION... /Issued 1103 PM EDT Fri Jun 30 2017/

UPDATE...
Earlier shower and thunderstorm activity has diminished with only
a few very light showers remaining at this time. Expect most of
tonight to remain fairly quiet with only a slight chance of
additional shower development. Otherwise, areas of patchy fog are
possible through the morning. Additional scattered showers and
thunderstorms are expected on Saturday, especially by afternoon.

PREV DISCUSSION... /Issued 255 PM EDT Fri Jun 30 2017/

SHORT TERM /Tonight through Saturday Night/...
Afternoon precipitation coverage has become less widespread and more
convective in nature. An abundantly moist atmosphere combined with
efficient warm-rain processes produced rainfall amounts of 1 to 1.5
inches this morning, with locally higher amounts, particularly over
western Georgia. The juicy air mass will remain over the state
through this afternoon before the responsible upper wave moves out
of the area, allowing precip to diminish into the overnight period.

Residual moisture over the area tonight, along with weak surface
flow will likely produce reduced visibilities overnight. At this
time, do not expect dense fog to be an issue, but localized or
patchy fog may be possible.

Expect Saturday's convection to be more diurnal in nature, with
little focus or steering, and slightly less overall coverage. Some
strong storms cannot be ruled out due to less cloud cover and
greater instability.

31

LONG TERM /Sunday through Friday/...
Along the northern periphery of an upr ridge over the GOM, north and
central Georgia will be within a W-NW flow aloft. This is a fairly
reasonable set-up for remnant upstream MCS activity to influence our
weather but timing and intensity of these "waves" are very
challenging several days out. The 12z NAM is most robust with energy
approaching the area late Sunday into Monday. We'll see how things
shake out in the next 24-36 hours but in any case, existing moist
and unstable airmass will support diurnally-driven isolated to
scattered mainly late day/evening convection through the week. Very
little fluctuation in temperatures expected unless we see a day with
widespread/persistent rainfall, which does not look probable at this
time.
