...Friday Afternoon Forecast Discussion...

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

A prefrontal line of showers and a few embedded isolated
thunderstorms continues to push eastward across the forecast area
this afternoon. The approaching cold front extends southward across
central Alabama from a surface low currently over the mid-
Mississippi Valley. Meanwhile, the last vestiges of a surface wedge
are slowly being scoured out of far northeast Georgia as the surface
front lifts northward. As far as the severe threat is concerned, the
limiting factor continues to be low surface instability despite
plentiful shear. With that said, through the reminder of the
afternoon, a marginal severe risk will remain given a strong low-
level jet and increasing low-level warm advection along the warm
front. Any thunderstorms that continue to be able to strengthen in
this zone would bring an isolated damaging wind gust or brief spin-
up tornado threat.

Otherwise, while PWs are elevated, quick storm motion has served to
limit overall precipitation accumulations. However, areas where
precipitation has had more of an opportunity to train from this
morning through this afternoon have received higher totals,
particularly across northeast Georgia. Localized minor hydrological
issues remain possible in these locations through this evening
by which time the rain tapers off.

By Saturday morning, the cold front will have made progress into
eastern/central portions of the CWA where it will stall. The morning
will bring a brief respite of drier conditions across much of the
area, with the exception of perhaps the far southeastern CWA. Dry
weather will be short-lived, though, as a shortwave lifts northeast
out of Texas into the ArkLaTex. This will induce the development of
a low along the front, and moisture will quickly surge back
northward into the area. Thus, PoPs will be on a quick increase from
tomorrow afternoon into tomorrow night, particularly across the
southeastern half of the area. No strong or severe thunderstorms are
expected given very weak instability. However, heavy rainfall totals
are possible in southeastern portions of the CWA, particularly
overnight tomorrow night where totals could approach 2". These
totals could be sufficient for localized minor hydro concerns,
though significant flooding issues are not expected.

.LONG TERM /Sunday through Friday/...

The long term period will be much quieter than the short term as
the forecast area returns to mostly clear and dry, diurnal
conditions following a cold front that will drop PWATS below 0.5
inches through at least Wednesday night. In the meantime, surface
high pressure will take hold with upper-level ridging aloft
allowing afternoon high temps to climb into the 50s and low 60s
each day for the first half of the week.

Afterwards, another synoptic trough will once again set up over
the eastern CONUS with a storm system expected sometime between
Thursday and Friday night. Models are beginning to come into
alignment but there are still major discrepancies as to the
timing of this frontal system, up to 18 hours in some cases, but
improving from timing differences during the previous shift. There
will also be an chance for some light snow showers for North
Georgia with some rap around moisture Thursday night into Friday
morning, but we'll have to see if colder temperatures continue to
hang around with the precip as the week progresses.

.AVIATION... 18Z Update... Shra and iso tsra affecting TAF sites
will gradually shift east through the afternoon. Tsra threat will
end at ATL sites and CSG by 19z with a threat at AHN/MCN through
around 22-23z. Otherwise, IFR cigs should remain largely the rule
through afternoon, though some brief, patchy improvement to MVFR
or even VFR remain possible at times. More persistent improvement
to VFR is more likely by 10-12z Saturday. Winds will shift from
SSE to SSW between 18-19z at ATL/CSG sites and remain SW
thereafter. Speeds as high as 10-12kts will diminish to 4-8kts by
evening.

//ATL Confidence...18Z Update...
Low to medium confidence on cigs through tonight.
High confidence on winds and precip timing.

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

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

Tornado watch in effect across portions of east and central
Georgia through 8pm.

Showers and a few thunderstorms are moving across the state this
afternoon. There is a risk for a few strong to severe thunderstorms
capable of producing damaging winds and even a brief tornado.
Locally heavy rain will also elevate the flood risk for low-lying
and poor drainage areas. The severe threat should end west to east
by early this evening.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...

Another round of showers and isolated thunderstorms are expected
across south-central Georgia on Saturday and Saturday night. A few
storms could become strong to severe, with damaging winds being the
primary hazard with any severe storms that occur. A localized flash
flood threat will also exist with additional heavy rainfall across
parts of central Georgia.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested today given the relative
isolated nature of any severe weather. However, spotters are
encouraged to submit reports of severe weather through the web by
going to weather.gov/atlanta. Please relay any information about
observed severe weather to the NWS while following all local, state,
and CDC guidelines.
