Area forecast discussion, Jun 9, 2:36 PM EDT, 2 hours 47 minutes before
Area Forecast Discussion
National Weather Service Peachtree City GA
236 PM EDT Tue Jun 9 2020

.SHORT TERM /Tonight through Wednesday Night/...
Scattered to numerous showers and thunderstorms this afternoon are
expected to diminish this evening with the loss of daytime heating.
With all the available moisture around, some lingering chances will
continue through the night over N GA.

A cold front approaches the area on Wednesday and will move to
central GA overnight. That will allow for another round of showers
and storms to develop Wednesday and Wednesday night.
A few storms could be severe with damaging winds as the main
hazard and some large hail will also be possible.

Forecast low temperatures are running about 5 to 13 degrees above
normal across the area tonight and near normal to about 8 degrees
above normal Wednesday night. Forecast high temperatures are running
within about 3 degrees of normal for Wednesday.

Overall confidence is Medium to high.

BDL

.LONG TERM /Thursday through Tuesday/...
No major changes made to the extended forecast. A cold front will
bring showers and thunderstorms to central Georgia Wednesday night
and continue across eastern and southern portions of the state
Thursday. With some lingering CAPE values in in the 1000 to 2000
J/KG range, there is the chance of a few strong thunderstorms to
form thursday afternoon as the front stalls. A stationary front will
linger along the coast, maintaining a diurnally driven chance for
showers and thunderstorms into the weekend. After the front moves
out, afternoon storms should be switched off by the dry air in place
over north and central Georgia this weekend and into early next week.

Dewpoints drop significantly behind the front from the 70s into the
50s and low 60s across the CWA on Thursday. Temperatures will be
moderated to near normal by the time the weekend rolls around.
Another front toward the end of the weekend will reinforce the dry
air. Given high pressure in place and northwest flow, precip with
this front is pretty unlikely.
