Area Forecast Discussion
National Weather Service Peachtree City GA
1108 AM EDT Sat Jul 20 2019

.UPDATE...

Heavy rain and thunderstorms are ongoing across far northwestern
Georgia. With high PWATs in excess of 2 inches and very slow
boundary layer winds, this precipitation has been nearly
stationary over this area for several areas, which has warranted a
Flash Flood Warning in the area. PoPs in this area have been
significantly increased as a result. Elsewhere in the area,
showers have begun to develop near the Atlanta metro area along
with some isolated showers across north Georgia. Scattered to
numerous thunderstorms are expected to develop in the afternoon
hours, especially across western Georgia. Otherwise, only minor
adjustments have been made based on the latest observations.

UPDATE...

12z Aviation update below.

PREV DISCUSSION... /Issued 416 AM EDT Sat Jul 20 2019/

SHORT TERM /Today through Sunday/...
Regime should stay fairly similar thru weekend as a broad/weak low
pressure and associated enhanced moisture field persists across the
northern Gulf states with very slow westward propagation. Have
likely pops in the west/north with chance elsewhere given the better
moisture axis. With PWATs near 2 inches in this area we could have
some isolated flash flooding potential with stronger convection and
cannot rule out a few with strong/damaging winds from enhanced
downdrafts. Thermal profiles progged to again have tall/skinny CAPE
so not expecting much of a hail threat with any stronger storms.
Have a bit lower pops for Sunday given more shifted aforementioned
low/moisture to the west, but still have 20 to 30 percent most
areas and 40 to 50 pops in the far north/NW. Temps look to be
right around climo norms with highs in upper 80s to low 90s (a bit
higher in parts of the east). Heat indices for now look to stay
below advisory level in that area but could make it into the low
100s.

Baker

LONG TERM /Sunday Night through Friday/...
Main concerns in long term period continue to be timing for
convection and likelihood that front will push through CWA next
Tuesday/Wednesday.

Model guidance still indicating large elongated upper ridge will be
replaced by more amplified pattern with high amplitude ridge over
the western CONUS and upper trough over the east half. Prior to and
during this transition, noticeable weakness in the upper ridge will
remain just to our west with deep moisture and slightly cooler mid
level temps.

Convection coverage may decrease a bit at start of long term period
on Monday with slightly drier air moving in from the east. However
as shortwave and front approach from the NW, moisture from weakness
gets pooled ahead of front so expect more widespread convection on
Tuesday. Guidance blend PoPs nearing categorical which matches well
with neighboring WFOs. Can't rule out chc of slightly more organized
strong/severe storms on Tuesday as well tho abundant clouds and
lingering stratiform precip in the morning may significantly limit
afternoon heating and instability. Heavy rain also likely in this
pattern but hopefully mean winds aloft and vertical wind shear will
be sufficient to keep storms moving and not remaining in any one
place for too long.

Models in better agreement on how far front will push but still
skeptical based on subjective knowledge of fronts making it that far
south in July. Guidance not going too crazy with cooler/drier air at
the surface so only small modification to model blend temps/
dewpoints. Did adjust PoPs a bit to keep slight chc and TSRA
lingering longer behind front based on uncertainty mentioned earlier.

AVIATION...
12Z Update...
VLIFR/LIFR cigs mainly 200-400 ft this morning then gradual
lifting/scattering after 13-15z. Area of showers and isolated TS
possibly pushing across the sites near ATL initially so have most
locations with VCSH. Cu field today 3-4 kft with more widespread SHRA/TSRA
again mainly 18-00z. Winds generally SW 3-7 kts through period
with higher mags in afternoon and possible VRB gusts with any
TSRA.

//ATL Confidence...12Z Update...
Medium on overall cig trend and precip coverage.
High on all else.
