Area forecast discussion, Jun 8, 3:15 PM EDT, 3 hours 44 minutes before
Area Forecast Discussion
National Weather Service Peachtree City GA
315 PM EDT Fri Jun 8 2018

.SHORT TERM /Tonight through Saturday Night/...

Current satellite image shows a cumulus field across the area with
isolated showers and thunderstorms on radar. These will continue to
develop before waning later on this evening. There is plenty of
instability across the area currently, so some thunderstorms may
become strong with gusty winds, heavy rain, and lightning being the
main hazards. Moisture will continue to increase and advect into the
area as the upper level low near the Big Bend region of FL continues
to shift to the northeast into southeast Georgia. The morning
sounding had a PW value of 1.42 inches, with forecast PWATS rising
to 1.5 to 1.9 inches through Saturday. As a result, Saturday will
bring another afternoon of mainly diurnal scattered thunderstorms
although coverage is expected to be higher than this afternoon. Have
chance pops across most of the area on Saturday with likely pops
edging into the mountains. Similar to today, we won't be lacking
in instability so some storms may become strong with gusty winds,
heavy rain, and lightning being the main hazards.

Overall high and low temps will remain above average through the
short term with Saturday being just a couple degrees lower than
today.

Reaves

.LONG TERM /Sunday through Friday/...

The extended forecast period continues to be characterized by
chances for showers and thunderstorms each day, especially during
the afternoon and evening. The weak upper low over south Georgia at
the start of the long-term period will be absorbed into the upper
trough over the southeast. With moist southerly flow and a
persistent upper trough across the east, the impetus for diurnal
shower and thunderstorm development will persist into next week.
Some thunderstorms may become strong with gusty winds and locally
heavy rainfall each day.

High temperatures will generally be near to slightly above normal
while lows will run several degrees above normal.
