Area Forecast Discussion...UPDATED
National Weather Service Peachtree City GA
627 AM EST Sun Jan 28 2024

...New 12Z Aviation Discussion...

.SHORT TERM...
(Today through Monday)
Issued at 307 AM EST Sun Jan 28 2024

Key Messages:

- Wind Advisory in effect until 7 AM Monday across far north-
  central and far northeast GA

- Wintry mix possible above 3000 feet across far north GA, but
  no impacts expected

- Dry, breezy (but below Wind Advisory criteria) conditions
  expected tomorrow (Monday)

The 500-mb shortwave trough currently churning over the OH/TN
River Valleys will continue its trek eastward through the day.
Closer to the surface, a CAA cloud deck in the wake of the cold
front passage will envelope the CWA, leading to noticeably cooler
high temps than those yesterday -- generally in the mid-40s to
mid-50s. West to northwest winds will be sustained at 13-18 mph
with gusts of 20-30 mph across much of the area. A Wind Advisory
has been issued for far north-central and far northeast GA as
sustained winds of 20-25 mph and gusts of 35-45 mph are forecasted
through early tomorrow morning, especially in the mountains.

There is a slight chance (25% or less) for light rain showers
(with QPF less than 0.15") across far north GA today through
tonight as relatively shallow moisture associated with the CAA
regime couples with upslope flow along the windward sides of the
mountains. Above around 3000 feet, a light wintry mix will be
possible after around 1 PM today until around 1 AM tonight.
Localized, minor accumulations of snow and/or freezing rain are
possible, but only at the highest peaks in the mountains,
including portions of the Cohutta Wilderness, portions of Vogel
State Park, and Brasstown Bald.

Overnight lows tonight into tomorrow morning will be in the lower
30s to lower 40s. The cloud cover will gradually clear through
the day tomorrow, allowing temps to rebound to highs in the upper
40s to around 60 (outside of the cooler, higher terrain of north
GA). High pressure will establish itself in the wake of the
departing shortwave trough and will keep conditions dry, while
northwest flow will keep conditions breezy, albeit below Wind
Advisory criteria.

.LONG TERM...
(Monday night through Saturday)
Issued at 307 AM EST Sun Jan 28 2024

- Apart from some very light precipitation in north Georgia
  Tuesday night or Wednesday, the prevailing theme for the
  upcoming week should be drier weather.

- Temperatures between Tuesday and next Sunday should be near or
  slightly above seasonal averages.

Tuesday through Wednesday:

The feature to watch during this time period will be a clipper
system diving southward through the Great Lakes and Mid-Atlantic.
Guidance from the last four runs of the EPS and GEFS has
continually shown very light (0.05 inches or less) precipitation
with this system over the mountains of northern Georgia. Guidance
from both ensemble systems indicates a greater than 80% chance of
0.01 inches of precipitation along the windward slopes of the
mountains, and 50 to 70% odds of 0.01 inches for other areas north
of Interstate 20. If we bump up to 0.10 inches the odds fall to
around 40% on the windward slopes and below 20% for other areas
north of Interstate 20. Since these odds have been consistent for
severe model runs, we can say with moderate to high confidence
that we are looking at a very light and uneventful precipitation
event Tuesday night into Wednesday morning. Forecast temperature
profiles suggest rain as the main precipitation type with this
event, though the higher peaks (above 2000 ft) in northeast
Georgia could see a dusting of snow by Tuesday night or Wednesday
morning. Locations south of Interstate 20 should stay dry Tuesday
and Wednesday, with increasing cloud cover being the only
indication that a shortwave is passing by.

Temperatures on Tuesday and Wednesday should be steady in central
Georgia, with afternoon highs in near 60 degrees. For northern
Georgia temperatures should cool slightly from Tuesday to
Wednesday. Look for highs in the upper 50s on Tuesday and the
lower 50s on Wednesday.

Thursday through Early Next Week:

A strong longwave trough will push into the West Coast during
this period. As this occurs it should promote the amplification of
an upper level ridge over the Plains. In lieu of any strong
shortwaves riding over the peak of the ridge, this pattern should
promote dry weather in Georgia through Saturday. In the current
runs of the EPS and GEFS around 90% of the members favor this dry
solution. At this time range uncertainty remains high, so the
remaining 10% of members that indicate light precipitation on
Saturday shouldn't be discounted entirely.

As we move into early next week the ensemble guidance (EPS and
GEFS) wants to allow a piece of shortwave energy to undercut the
ridge over the West. This suggests rising precipitation chances
early next week, especially with the majority (> 90%) of EPS and
GEFS members indicating accumulating precipitation in Georgia
between Sunday and Tuesday. Shortwaves undercutting a ridge as the
ensemble guidance suggests are fairly unusual, and when they do
occur guidance often struggles with the timing. Thus our
confidence in the timing of any rain early next week remains low.

.AVIATION...
(12Z TAFS)
Issued at 603 AM EST Sun Jan 28 2024

The only impactful change to the forecast since 06z is to keep
CIGS MVFR at PDK and RYY rather than going IFR as the 06z TAFs
had. Otherwise, still expect MVFR CIGS to prevail through the
majority of the forecast period at all TAF sites. Visibility
restrictions are not expected. W to NW winds will be 12-20 kts
with gusts of 22-30 kts, even through late tonight.

//ATL Confidence...12Z Update...
Medium to high confidence on ceilings.
High confidence on all other elements.
