National Weather Service Peachtree City GA

.SHORT TERM /Tonight through Wednesday Night/...

Another very warm afternoon across north and central Georgia with
2PM temperatures ranging from the upper 80s far northwest GA to
upper 90s in our far southeast areas (Eastman/Dublin/Vidalia). Low
to mid-lvl ridge over the area is helping to suppress convection
which should continue through the remainder of the afternoon/evening
hours.

Heading into tomorrow (Wednesday), remnant energy from "Barry"
over Arkansas finally moves east across the Tennessee Valley and
over the southern Appalachians. This will increase the chance for
showers and a few thunderstorms mainly across north Georgia, with
locally heavy rain the primary threat - especially given the
sub-tropical airmass in place. Shortwave energy within NW flow
expected to affect the area Wednesday night into Thursday so will
maintain low-chance POPs across north GA during this time.

DJN.83

.LONG TERM /Thursday through Tuesday/...

Only tweeks made to the long term forecast. Thursday and Friday heat
indices have drop 1-2 degrees with the latest guidance, however, we
will continue to be near Heat Advisory criteria and careful
attention will need to be monitored carefully going into the middle
of the week. Low-resolution model runs for precipitation continue to
have discrepancies, but with substantial low-level moisture...GFS
showing PWATS around 2 inches Thursday through Saturday...trapped
under the broader synoptic ridge, we`ve bumped rain chances up
slightly in areas with concentrated moisture and accumulations
across multiple model runs exist.
