Area Forecast Discussion
National Weather Service Peachtree City GA
326 PM EDT Thu Sep 17 2020

.SHORT TERM /Tonight through Friday Night/...

Only light rain showers are scattered across the forecast area
this afternoon from the remnants of Sally. The center of what
remains of Sally will continue to gradually push east-
northeastward out of the forecast area through this evening. Any
lingering wraparound light rain showers will also come to an end
through late evening as this occurs. Fortunately, any additional
QPF will be very light and not exacerbate ongoing flooding of
streams and rivers caused by the very heavy rainfall last night
and early this morning.

On Friday, the main story (other than ongoing river flooding) will
be a cold front pushing into the state. Mainly dry but cloudy
conditions are anticipated ahead of the front, though there may be
sufficient lingering moisture for a few isolated showers in central
Georgia tomorrow afternoon into tomorrow night. Otherwise, tomorrow
will mark the onset of a period of very fall-like weather as cooler
temperatures and lower dewpoints begin to filter southward.

RW

.LONG TERM /Saturday through Thursday/...

Much of the long term forecast will be quiet, with below normal
temperatures and dry conditions.

An upper level shear axis will set up across the southern CWA late
Friday into late Saturday. This feature may help provide some upper
lift across the southern third of the outlook area, but with drier
air moving in from the north, pops should be limited. Not much
surface instability and lapse rates remain weak, so thunder chances
should remain fairly isolated. The shear axis gets nudged southward
by early Sunday as a longwave trough pushes off the east coast. The
CWA should remain in weak NW flow aloft for the remainder of the
forecast period.

At the surface, high pressure will begin building in from the north
early Saturday. The high center will build down the spine of the
Appalachians through the weekend into early next week.

.AVIATION...
18Z Update...
Lingering very light shra around the remnant center of TD Sally
remain possible before largely tapering by 00z. Cigs have begun
to improve to MVFR at most TAF sites though patchy IFR remains,
mainly near AHN. Cigs will likely range from MVFR to VFR at ATL
sites tonight with more persistent improvement to VFR more likely
by Friday afternoon. Wind speeds will continue to lessen to
around 8-12kts through evening with a few gusts 15-20kts through
20z. Initial NE direction should begin to shift toward NNW around
and after 00z.

//ATL Confidence...18Z Update...
Medium confidence.
