749 AM EDT Thu Oct 29 2020

.PREV DISCUSSION... /Issued 350 AM EDT Thu Oct 29 2020/

..Remnants of Tropical Storm Zeta currently tracking across
western and north Georgia bringing strong gusty winds to the area
early this morning...

SHORT TERM /Today through Friday/...

Tropical Storm Zeta currently over central AL will rapidly move
across portions of west and north GA, exiting the forecast area by
mid to late morning and continuing to the northeast. An upper
level short wave will push across portions of north GA late this
evening, helping to push the surface low east of the area. Surface
high pressure will begin building into the area Friday afternoon.

As Zeta moves across the area this morning light to moderate rain
showers will continue across north and much of central Georgia.  1
to 2.5 inches of rainfall is expected through Friday morning across
areas along and north of I-85, with locally heavier rainfall
possible across portions of north GA. A Flash Flood Watch will
remain in effect through 8pm tonight.  Zeta will spread a swath of
up to 50-70 mph wind gusts again mainly along and north of I-85 as
Zeta moves across the area through 8am or so this morning.  Wind
will remain gusty this morning, however maximum wind gusts will drop
into the 20-30 mph range with isolated 15-25 mph gusts possible this
afternoon.

Low to mid clouds this morning will slowly improve through early
afternoon, with clouds scattering by late afternoon across much of
the area, however as the short wave moves across this evening
clouds will linger across portions of north GA into the late
evening hours.

With rapidly changing conditions through much of the forecast
period, guidance temperatures are in general agreement through the
period and stayed with a blend of guidance.

Atwell

LONG TERM /Friday Night through Wednesday/...

A much more benign and quiet forecast remains in the long term
with mainly dry ridge dominated and abnormally cool airmass in
place. Only main influencing feature to speak of is with a mostly
dry reinforcing cold front on Sunday. There is some potential for
an area of enhanced low level moisture advecting northwestward
off the Atlantic ahead of the front so have included a small zone
of slight pops for light rain in the far northeast CWA late
Saturday into Sunday.

What is more impactful will be the much cooler temps and possibly
coldest of the season so far to be ushered in behind the front
for Monday morning and Tuesday morning. The current forecast looks
to have some low 30s and freeze potential in the far NE higher
elevations early Monday and while other parts of north GA could be
in the mid 30s the enhanced NW gradient winds should limit frost
potential. Tuesday morning on the other hand looks to be even
cooler with lax winds so is a better bet for not just freeze
potential in the NE but also frost across much of the rest of
north GA. Central GA looks to be more in the upper 30s with this
update, but overall guidance has trended cooler than yesterday.

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

.DAY ONE...Today and Tonight...

A Tropical Storm Warning is in effect until 11 AM this morning
across north Georgia and portions of west central Georgia. Maximum
sustained winds of 25 to 35 mph and gusts up to 60 mph are
possible, which will bring down trees and powerlines. Other areas
southeast of the warning area are in a Wind Advisory for winds of
15-25 mph gusting up to 45 mph.

While the majority of rainfall and the flash flood threat is
diminishing across north Georgia, lingering runoff may cause
minor flooding of rivers, creeks, and streams.

For more detailed information on Tropical Storm Zeta, please
refer to the Hurricane Local Statement at weather.gov/atlanta.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday...

A strong cold front, while mostly dry, will bring some of the
coldest temperatures of the season to the area for Monday and
Tuesday mornings. The far northeast mountains could have freezing
temps in the low 30s both mornings and other areas in north
Georgia could have some frost concerns mainly Tuesday morning.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested but 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
