Severe Thunderstorm Warning 275, NWS Atlanta, GA

Area Forecast Discussion
National Weather Service Peachtree City GA
221 PM EDT Wed Aug 14 2019

.PREV DISCUSSION... /Issued 1052 AM EDT Wed Aug 14 2019/

UPDATE...

Fairly quiet morning will continue across the area as the
remaining showers have fizzled out and the remaining areas of
patchy fog have cleared, leaving just some isolated areas with
some lower level cloud cover. No changes were made to the
previously issued Heat Advisory as temperatures continue to rise
across the area. Current heat indices across the area are in the
upper 80s to near 100 across far central Georgia within the Heat
Advisory area. This afternoon the highest coverage for showers and
thunderstorms is expected to be across central Georgia as the
front continues to sink south through the area. A few strong to
isolated severe still will still be possible across mainly central
Georgia. Otherwise, no other changes besides tweaks to
temperature and cloud cover were necessary for the short term
forecast.

UPDATE FOR AVIATION...

PREV DISCUSSION... /Issued 332 AM EDT Wed Aug 14 2019/

SHORT TERM /Today through Thursday/...

The heat advisory for today for central and a small portion of N GA
will continue with the max heat indices running about 103 to 109
degrees.

Otherwise the main concern is a slow moving cold front over N GA that
is forecast to drift toward central GA during the short term period.

Showers and storms across portions of N and central GA this morning
are expected to weaken.

The best moisture and instability line up across central GA later
today that will allow for the development of numerous showers and
thunderstorms during the afternoon and evening hours. SPC has also
indicated a marginal risk for severe thunderstorms across central GA
with damaging winds the main hazard along with frequent lightning and
locally heavy rainfall.

With the front stalling across roughly central GA on Thursday and the
best moisture tending to move east and south, central GA will have the
highest pops on Thursday with N GA expecting no rainfall.

Forecast high temperatures are running around normal to as high as 8
degrees above normal across the area today and similar on Thursday.
Forecast low temperatures are running about 1-7 degrees above normal
tonight.

Overall confidence is medium to high.

BDL

LONG TERM /Thursday Night through Tuesday/...

No significant changes to the long-term forecast trends. Medium-
range models continue in fairly good agreement through the extended
forecast period, keeping the region under the influence of a broad,
weak upper trough stuck between the central U.S. and western
Atlantic upper ridges. Weak surface troughing persists through the
weekend with the western edge of the western Atlantic surface ridge
building back into the region by early next week.

This Hazardous Weather Outlook is for portions of North and Central
Georgia.

.DAY ONE...This Afternoon and Tonight...

Scattered to numerous thunderstorms are expected this afternoon and
evening, mainly over areas south of I-20. A few strong to marginally
severe storms are possible with strong winds, frequent lightning and

north Georgia this afternoon into early this evening, generally along
and south of a line from Franklin to Conyers and Lexington. Heat
index values will range between 105 and 109 degrees. High heat and
humidity will cause heat stress during outdoor exertion or extended
exposure.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

Afternoon and evening thunderstorms will be confined to areas south
and east of Macon Thursday and Friday, but chances will increase
across the state beginning Saturday. Some storms could be strong
with gusty winds, heavy rain and frequent cloud-to-ground lightning.
