Area Forecast Discussion
National Weather Service Peachtree City GA
303 PM EDT Sat May 11 2019

.SHORT TERM /Today through Monday/...

The CWA remains situated in the warm sector this afternoon as a warm
front extending from eastern Tennessee southwestward into southern
Louisiana continues to lift northward. Meanwhile, southwest flow
persists aloft with a series of disturbances continuing to enhance
convective activity. A remnant MCV pushing east-northeastward from
eastern Alabama into west-central Georgia this afternoon has
provided an impetus for shower and thunderstorm development in an
environment characterized by 1500-2500 J/kg of SBCAPE. While shear
remains relatively unimpressive, the slightly enhanced shear
associated with the MCV in combination with the aforementioned
SBCAPE will yield some strong to severe thunderstorms in central
Georgia with damaging wind gusts and hail this afternoon.
Additionally, PWs over 1.5" indicate ample moisture for locally
heavy rainfall.

The next shortwave currently sparking shra/tsra development to
the west in Mississippi will approach the area overnight into
Sunday morning providing a focus for additional rainfall. Prodded
by an upper low dropping into the Midwest, the cold front will
finally begin to make southeastward progress by Sunday. While
convection will likely be ongoing across portions of the area
Sunday morning, additional development is expected by late morning
into midday ahead of the approaching front. SPC maintains a
Slight Risk for areas along and southeast of the I-85 corridor
Sunday given forecast instability of 1000-2000 J/kg and more
favorable deep layer shear. Primary risks will be damaging wind
gusts, though large hail will also be possible. A brief tornado
can also not be ruled out. Thunderstorms will exit southeastward
from late Sunday afternoon into Sunday evening as the front pushes
across the area. Noticeably drier and cooler air will begin
filtering into the area from the north Sunday night into Monday
morning.

RW

.LONG TERM /Monday Night through Friday/...

Loaded in the latest guidance from the National Blend but overall,
very limited changes to pops as we enter into a relatively dry
period. We do have a secondary front approaching for Wed and Thu
with an increase in instability noted for Thu afternoon but only
isolated thunderstorms advertised at this time.

.AVIATION...
18Z Update...
An active TAF period will be characterized by periods of shra and
tsra. Shra and tsra will initially continue to increase this
afternoon with the most likely time frame for tsra at ATL area
sites from around 18-22z. Overall shower coverage is expected to
diminish somewhat this evening with shra potential again
increasing by Sunday morning. Additional tsra coverage will again
increase by 14-16z Sunday. Patchy MVFR cigs this afternoon are
expected to continue to gradually increase to VFR in the 040-050
range before MVFR cigs become likely again by 06z Sunday. Winds
will remain SW 05-08kts before increasing to 10-13kts with gusts
to 15-18 kts after 15z Sunday.

//ATL Confidence...18Z Update...
Medium confidence on cigs as well as shra/tsra timing.
High confidence on winds.
