River Flood Warning 226, NWS Atlanta, GA

Area Forecast Discussion
National Weather Service Peachtree City GA
641 AM EST Mon Dec 23 2019

.PREV DISCUSSION... /issued 302 AM EST Mon Dec 23 2019/

SHORT TERM /Today through Tuesday/...
Upper low very apparent on current regional radar mosaic along the
extreme southern Alabama and Mississippi border. Surface reflection
on latest analysis is further north and extends into south Central
GA as well. Light to moderate rain continues to spread northward of
this feature and impact most of the forecast area although drier air
is beginning to move into portions of SW GA and into the local area.
Continued windy conditions and will maintain Wind Advisory through
12Z. Likewise will hold onto Flood Watch given continued rains.

For the remainder of today, upper low will finally begin to kick out
and progress across the Florida panhandle. Coastal surface low will
then take over and track up the Carolina coast. This will allow for
a more NE trajectory to the surface flow and wrap around precip on
the back side of the low. With influences from the upper low, this
activity could be a little more showery in nature and will include
in the latest grid set. Will still carry categorical pops for the
eastern tier for most of the day, transitioning to likely pops late
in the day.

Ridging aloft finally takes over late Mon night into Tuesday
allowing for drying conditions. Will be quite warm for Christmas Eve
as well with temperatures in the mid to upper 60s areawide.
There will be some residual cloudiness for the SE zones, but this
too will exit the area during the afternoon hours resulting in
mostly sunny skies.

Deese

LONG TERM /Tuesday Night through Sunday/...
Quiet weather is expected Christmas eve and Christmas Day as
high pressure moves to the area.

A week cold front is forecast to move to the area over the
weekend bringing a chance of light rain and showers, most so
Saturday Night and Sunday. Instability is limited so thunderstorms
are not expected at this time.

Temperature are expected to be well above normal much of the long
term period.

.AVIATION...
12Z UPDATE...
There continues to be a mix of IFR and MVFR although most of this
should transition to just IFR within the next few hours. Still
looking at cigs going as low as OVC006 and persisting through the
morning hours. Main change for this cycle has been to delay the
improvement to MVFR and just keep conditions IFR for most all of
today. Widespread -RA can be expected as well. ENE winds will
remain gusty, particularly at ATL area sites. Gusts should
gradually begin to taper through today.

//ATL CONFIDENCE...12Z UPDATE...
Medium on IFR duration.
High on remaining elements.
