December 29: Arctic Air on the Way

A strong arctic front is headed toward Middle Tennessee. A big temperature change is in store for the second half of the weekend. Today reached 40° in Nashville, after falling to 19° this morning.  A few more clouds will move in tonight ahead of the front so tonight will be in the mid 20s instead of the teens.

Just like today, the jet stream will start out north of the midstate so Saturday will be relatively mild as well, around 40 for a high early in the day.

But the cold air will slide southward tomorrow afternoon. And stay that way for days to come.


The sharp cool down will be most evident on New Years Eve and New Years Day. Temperatures will only reach the upper 20s during the day.  That means it will be cold for fans to cheer on the Titans.  Wind chills will be in the teens.


By midnight when the music note drops it will be down right frigid with single digit wind chills.


Bitterly cold air will linger all week, with no significant chance for rain, snow, or ice in sight.


A side note for January 1, the first of two January full moons will shine bright on the first evening of the year. This will also qualify as a supermoon since it occurs only 4.5 hours after the moon reaches lunar perigee. The perigee is the moon’s closest point to Earth in it’s monthly orbit.  Therefore this moon will appear to be the largest and brightest supermoon of 2018.
