Area Forecast Discussion
National Weather Service Peachtree City GA
433 AM EST Tue Nov 12 2019


.SHORT TERM /Today through Wednesday/...

  • Brief Wintry Mix Possible in Far North Georgia This Morning

Satellite analysis this morning indicates a very impressive
troughing pattern from the eastern Great Lakes down the western
Appalachian then over into central Texas. Along it, radar shows a
band of precip, mostly consisting of rain with reports of some sleet
and snow on the rear of the line as an Arctic cold front has quickly
plunged into the northwestern forecast area, which will bring
unseasonably cold temperatures along with it. Behind the front, an
extremely large area of subsidence shows the extent of the Arctic
high pressure behind the frontal system. The center of the high
currently sits in the central plains with a central pressure around
1043hPa.

Throughout the morning, the cold front will continue quickly pushing
southeast with the entire forecast area expected to be behind the
front by noon today. Behind the front, strong gradient winds will
prevail with sustained winds up to 20 mph and gusts between 25-35 mph
possible. A Wind Advisory has been issued through 7 PM.

As the line of precip moves through the area, most of us will see a
little over a half inch of rain in total with temperatures varying
widely across the forecast area as the cold air move into the
region. In the far northern portions of the forecast area, a race
between subfreezing air moving into the area and drier air behind
the front eroding away the precip will determine if and how much
wintry precip could occur. Model guidance has been very consistent
with this system for several days and have been pushing towards a
transition from rain to a mix of snow and sleet, to a chance for an
hours-worth of light snow before the precip dries up in the cold,
dry airmass. Chances for any wintry precip will be primarily
confined to the northernmost 2 rows of Georgia counties and will
have the best chances in areas over 2000 feet in elevation.
Roads in
these higher elevations could become slick by early morning where
temperatures fall below freezing for an extended period of time. Any
accumulations of wintry precip are expected to be minor and not
cause significant impacts at this time. For more details, please see
the most recent Special Weather Statement.

While temperatures this afternoon are expected to stall as cold air
advection is countered by diurnal heating, tonight temperatures will
plummet once the sun begins going down and the skies clear. These
will be by far the coldest temperatures of the season with Columbus
and Macon in danger of setting record low temperatures. Lows are
forecast around 20 for far north Georgia and mid- to upper-20s are
forecast along and southeast of the I-85 corridor. A Freeze Warning
has been issued for the remainder of our forecast area where the
Autumn Frost/Freeze program remains in effect.

Tomorrow, the high pressure will be moving across the central
Appalachians into the Mid-Atlantic, and will dominate the weather
pattern. Clear skies will allow high temps to climb back into the
mid- to upper-40s, with light winds out of the east becoming breezy
during the afternoon.

The smokies are a real buzz kill when it comes to cold fronts up here. It takes so long for that cold to get past them from the NW. It's 32 in Blairsville and 45 here lol

NW flow can create downslope winds which warm also. You see that often. It was easy to see on the visible satellite images today, there was a sunny area surrounded by clouds.
