...New 12Z Aviation Discussion...

.SHORT TERM...
(Today through Wednesday)
Issued at 457 AM EST Tue Dec 31 2024

Current satellite is showing an area of low clouds around 400-600ft
across much of western Georgia extending into the Athens area. This
trend should stick around through the next couple of hours before
the front currently over Alabama pushes through between 10am and 1pm
today. As the low pressure system over the mid MS valley moves
further east today the associated front will also push through.
There are some isolated areas of drizzle out there over west Georgia
and showers over northern Georgia. These are expected to continue
through the early morning hours ahead of the front. Some isolated
showers are possible to continue into the evening in the far
northern portions of northern Georgia and although the precip type
is expected to be rain there is the low chance that a few flurries
could affect the highest elevations.

Following the frontal passage, expecting to see winds start picking
up with wind gusts up to 30 mph expected this afternoon into
evening. Temps tonight will also be in the mid to upper 30s which is
3-5 degrees above normal still, but definitely a change from the 10-
15 degrees above normal we've experienced the past couple of days.
These temperatures could result in areas of patchy frost tomorrow
morning

.LONG TERM...
(Wednesday night through Monday)
Issued at 457 AM EST Tue Dec 31 2024

Key Messages:

  - Several shots of cooler air will keep temperatures seasonable to
    slightly below average through the end of the week into the
    weekend.

  - Next shot of rain (and possibly some winter precip mixed in
    across far north Georgia) will be Sunday into Monday next week.

Forecast:

Wednesday night sees zonal flow over the CWA. Significant portion of
the tropospheric polar vortex has been pushed over the north
American continent, which is opening the door for multiple waves of
cooler air to come pushing into the Great Plains and eastern US.
Several shortwaves will push by the area through the end of the
week, but the most potent one looks to come through on Thursday
night into Friday morning. The good news is this wave doesn't have
much in the way of moisture to work with and doesn't produce much in
the way of rainfall at this time. The bad news (unless you like the
cold) is it will push yet another shot of cold air in that will
bring temperatures does into the 20s Friday night across much of the
CWA, the potential exception being east central Georgia which may
stay a balmy 30-32. High temperatures on Saturday only make it up
into the upper 30s to low 40s in north GA and the metro, and mid to
upper 40s in central Georgia.

The next system to talk about is a potent wave that moves into
southeast Sunday night into Monday, developing a strong low that
appears to be able to tap into the subtropical jet and pull some
moisture up this way. Model consensus as of the 00Z runs is pulling
the system a bit further to the north compared to some of the
earlier runs, which would act to limit snowfall potential
substantially in all but far northern Georgia and the Appalachians.
NBM probabilities for seeing at least 0.1" of snow are 10-20% in
these areas. GEFS and EPS forecasts mirror this unsurprisingly,
showing mean 24 hour snowfall totals of around an inch in the
mountains. This forecast package maintains the rain/snow mix in
these areas. Outside of the mountains, it does appear that a decent
push of moisture will move through and give the rest of the state
what is likely to be a chilly rain at this time.

Want to take a moment and talk about next week. You are likely to
see plenty of social media-ologists posting model runs that could
show big snow totals across parts of Georgia. Snow in Georgia is
challenging to make happen. In many ways, it is like baking a cake.
First, you have to have all the right ingredients - forget one, and
the whole thing collapses. Next week, it looks like we will have the
possibility for all the necessary ingredients to come together over
the southeast and Georgia. However, then you have to bring all those
ingredients together at the right time and in the right amounts.
That is the really challenging part to forecast. Right now, small
changes in the positions of all the features - cold air, moisture to
south, the potential waves that will form the storm systems, etc -
create very different outcomes in the models. This is part of why we
run ensemble systems that allow us to test making small changes to
the models to see how it affects the outcomes. Looking at the
ensembles, they currently put the probability of seeing some decent
snow somewhere in Georgia at around 10-20%. So, the best thing this
forecaster can say is to stay tuned to the forecast, and know that
we will be entering a period of time where snow is possible anywhere
in the state. That's not something we see too terribly often, but
even with the increased chance, it is still just a chance. It may
not come together right. And last, friends don't let friends share
10-day-out snow maps on social media :)

.AVIATION...
(12Z TAFS)
Issued at 623 AM EST Tue Dec 31 2024

Current IFR deck with scattered pockets of LIFR should stick
around through 14-15z before beginning to scatter out as the front
currently across Alabama pushes into the area. Following the
frontal passage, should see skies begin to clear and SW winds to
become gusty with gusts between 25-30kt expected through 23z.
There is the potential for MVFR overnight into tomorrow morning.

//ATL Confidence...12Z Update...
Medium to High on all elements except MVFR CIGS tomorrow morning
which is low to medium confidence.
