...Afternoon Area Forecast Discussion...

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

Some heavy rain showers and the occasional thunderstorm continue
to pop across the CWA, especially in north GA, within the warm,
moist airmass ahead of the front. SPC SfcOA mesoanalysis shows
decent instability across the area with the day time heating with
a belt of 2000+ J/kg of CAPE just south of the I-20 corridor.
Despite decent instability, lack of forcing/shear and paltry mid
level lapse rates are preventing better organization of storms. Better
upper level forcing will continue to move into the area as the
front moves in and the pre-frontal trough should provide a nice
lifting mechanism for storms as can already be noted by the more
vigorous convection ongoing across Alabama. Expect this will
arrive into the area by in the next few hours, pushing across the
state as a broken line of storms. Can't rule out a damaging wind
gust, especially across north Georgia, but do expect these will
quickly taper off with sunset and loss of instability.

Only concerns overnight appear to be the low cloud deck for
aviation. Some models do hint at some patchy fog, especially
before the actual front arrives tonight to remove the moisture,
but have opted not to put that in the forecast for now, as winds
may stay up enough to prevent those concerns. Tomorrow looks to be
a great day across north GA, with highs in the upper 60s (!) and
70s with clear skies. Central Georgia will have to wait for the
front to clear them to get in on the nicer weather, so highs will
still be in the mid to upper 80s with some chances of rain.

.LONG TERM /Sunday through Friday/...

Starting off the long term dry on Sunday for Sunday with the
aforementioned system in the short term progressing eastward out
of the DelMarVa area. This dry trend is expected to continue
through early next week with mid-level zonal flow and surface high
sinking down through the Ohio River Valley. Expecting precip
chances to increase moving into Wednesday through the latter half
of the extended thanks to a turn to SW flow aloft with a shortwave
trough over the Southern Plains phasing into a long wave as it
moves eastward. Current QPF totals for Wednesday through Friday
for N Georgia are in the 1.0-2.0" range, with isolated pockets of
locally higher amounts within the N Georgia Mtns. Elsewhere,
seeing lower amounts around 0.5" for most of central Georgia.

.AVIATION...
18Z Update...
SHRA/TSRA have begun in and around the metro TAF sites as well as
CSG, with RYY being impacted as of this update. These will be
spotty through the afternoon until front arrives this evening,
pushing better TSRA through around 22-24Z for metro and a little
later for CSG, MCN, and AHN. Winds will be SW/W today across sites
8-12 kts with gusts up to 20. MVFR cigs tonight, with the
possibility of reaching IFR at some. Some uncertainty around
reaching IFR in metro, have chosen not to go at ATL.

//ATL Confidence...18Z Update...
Medium confidence on cigs tonight (see above), high all other
elements.
