Winter chill for Atlanta

It was still November when I first warned that this big cold front was coming and that rumors of snow would come with it. While the rumors were spread by others everyone now agrees on the coming cold.

The pattern is highly volatile thanks to the jet stream screaming right over Georgia with embedded “short-waves” or upper-level disturbances or spokes of vorticity which are notoriously difficult to time. Thus, expect forecasts to need adjusting every 6-12 hours between now and Saturday.

YES, there are multiple “opportunities” for snow flakes in Georgia, even Atlanta. However, to me NONE OF THEM look significant enough to focus on or worry about as of now.

Obviously this could change.

After a half inch rain (on average) and lightning/thunder in a couple spots we turn colder than normal and won’t see the 60s again for at least the next 10 days.

Multiple hard freezes are coming with the coldest air of the season thus far.
