Area Forecast Discussion
National Weather Service Peachtree City GA

.PREV DISCUSSION... /Issued 327 PM EDT Mon Sep 30 2019/ 

SHORT TERM /Tonight through Tuesday Night/...

High pressure aloft that was previously centered over the area has
shifted west some, allowing for moisture riding along the periphery
of the high to move into the area. This will allow for chances for
showers and thunderstorms across the area this afternoon and
evening, although mainly across the mountains and other portions 
of northeastern Georgia. At the surface, high pressure pressure
will continue to build into northeastern portions of the area as a
backdoor front slowly moves in. With much of the rest of the area
remaining dry today is expected to another hot day with high
temperatures about 15 to 20 degrees above average with highs in 
the mid to upper 90s across the area. As of this writing, 
preliminarily, Atlanta has already beaten the previous high 
temperature record (91 degrees from 1941), Athens has currently 
beaten the record (96 degrees from 1933, 1911), as well as Macon 
(95 degrees from 1954/1904). Precip should taper off late this
evening and overnight lows are expected to be in the upper 60s to
low 70s.

For Tuesday, moisture continues to be trapped under the ridge as 
it begins to flatten. As such, have continued slight chance to 
low end chance pops across the mountains for Tuesday afternoon and
evening with the rest of the area expected to remain dry. With 
the flattening of the ridge, high temperatures on Tuesday will be
in the upper 80s in the mountains with lower 90s across the rest 
of the area. Still, at least the high temperature record at
Atlanta will be in jeopardy for Tuesday, where the record high is
89 degrees.

LONG TERM /Wednesday through Monday/...

The upper level ridge is expected to remain in place over the 
southeastern CONUS through Thursday, keeping temperatures hot 
through much of the week. During this time, high temperatures are 
anticipated to reach into the mid to upper 90s, or 12 to 18 
degrees above climatological normals, over much of the north and 
central Georgia. These highs will continue to meet or break 
records across the forecast area. The influence of the ridge will 
also keep conditions fairly dry and precipitation chances limited 
across the area.

On Thursday and Friday, the upper ridge will begin to weaken and 
become increasingly elongated. Meanwhile, an upper level trough will 
move eastward across the upper Great Lakes region and into New 
England on late Thursday/early Friday. A surface low associated with 
this trough will drop a cold front into the region, which will move 
from northwest to southeast through the forecast area Thursday night 
into Friday. Model guidance is trending towards better agreement 
that very little precipitation will be associated with this feature. 
Temperatures will then gradually cool after the passage of the 
front, with highs in the low to mid 80s by Sunday. High temperatures 
each afternoon will still remain above average, but at the very 
least are expected to get out of record breaking territory.
