Good Monday morning!

I know many of the teachers are off today while other people have a few more days to work before the Thanksgiving holiday. The week will be mild as we are trapped in a progressive zonal flow where the upper level steering currents are moving west to east, and those winds will be bringing several chances for rain through the weekend.

Before we get to next week, the Atlanta NWS office has this to say about this current week and Thanksgiving.

An active and progressive pattern is expected through the long-term
period.
Upper-level southwesterly flow over the area ahead of an
advancing trough will lead to continually increasing moisture over
north and central Georgia as the period begins on Tuesday night. A
strengthening surface low associated with this trough will move
northeastward from the midwest towards the Great Lakes region from
Tuesday night through Wednesday.  A cold front extending south from
the low will then approach the forecast area from the west on late
Tuesday into Wednesday. Isolated to scattered showers ahead of the
cold front are anticipated to enter northwest Georgia Tuesday night.
Showers are then expected to become more widespread and push south
and east during the overnight hours, with likely PoPs in place
across north Georgia by Wednesday morning.

The highest PoPs and heaviest rainfall are currently expected across
north Georgia, generally along and north of the I-85 corridor on
early Wednesday.
Diminishing chances and rainfall amounts are
anticipated progressively further south, with the front weakening as
it pushes into central Georgia on Wednesday afternoon. Precipitation
totals ahead of this front are currently expected to be between 1/4-
1/2 inch along and north of the I-85 corridor and less than 1/4 inch
or less south of the I-85 corridor.
The front clears the area to the
southeast late Wednesday night, with cool conditions and clearing
skies Wednesday night into Thursday morning.

A persistent upper ridge is then anticipated to build over the
eastern CONUS during the day Thursday and linger until the next
frontal system approaches the area during the weekend. This ridge
could keep the moisture fetch across northern Georgia, with slight
chance to low-end chance PoPs on Thursday and Friday across the
northern half of the forecast area. The influence of the ridge will
furthermore lead to mild temperatures and gradually increasing
humidity through the end of the week.

 

So not a bad Thanksgiving. No snow and no severe weather help to keep things pretty safe weather-wise.  But this mild period must come to an end, so look for the weather to shift gears over the weekend.

Model guidance is beginning to come into better agreement with
respect to the system expected to impact our area this coming
weekend. Latest GFS and ECMWF solutions indicate precipitation ahead
of a strong cold front entering north Georgia during the day
Saturday and advancing southeastward through the forecast area
overnight and through the day Sunday
. Instability associated with
this system still appears to be limited at this time, but broad
forcing ahead of the front could be sufficient to support the
development of isolated thunderstorms. A slight chance of thunder
has been added on Sunday in portions of north Georgia, as a
result.

 

And cold it gets. Here are a look at the temp anomalies as well as temperatures at 1 PM Monday (GFS and Euro) following the frontal passage. Great way to start meteorological winter! 🙂

Needless to say, it will be much cooler to start December. 

I hope everyone has a great day today and if you're traveling, please be safe! 🙂  
Have a great day!

Winter begins in 26 or 6 days. 🙂 I think in 6 you'll come around to my way of thinking. 🌡️❄️🤶🎅⛷️
