Blast of cold air this weekend and first week of the new year!

New Year's Day Highs

Prepare over the next 24 hour with highs in the mid 40s on Saturday, early. By Saturday night, the freezer doors open.

First thing first. After Wednesday’s “increased chance of snow”, as somewhat expected, the COLD, DRY air will win out pushing Sunday’s moisture south of us. We may not see any moisture for the next week and a half.

Now for the cold. It’s coming. At this point not record breaking, but coldest we’ve seen this season, and a much longer duration than we’ve seen since Dec. 2010. I highlighted a tweet on air from DeKalb county were they are opening warming shelters Sunday/Monday nights. I imagine most places will for the entire week. Now we did have a high of 30 back in January of this year, so we may not quite be the “coldest we’ve seen in years”, however IF we stay in the 20s on Monday, it will be the coldest since Feb of 2015.


  • By late Saturday night we will drop into the 20s and wind chills in the teens.
  • Sunday highs in the upper 20s to the mid 30s and breezy. Wind chills in the 20s. (Titans game will be in the 20s, WC in the teens!) Winds N 10-20mph
  • New Year’s Eve all should fall into the teens for lows and continued breezy making it feel like the single digits.
  • New Year's Day will feature a mix of sun and clouds (more clouds in the PM). Still a bit breezy as highs struggle to make it to 30! It will feel like the 20s all day.
  • Winds ease on Tuesday, and a brief warm up on Wednesday (the upper 30s, Yeah).
  • Another, possibly COLDER blast, could move in next Thursday…we’ll see.
  • As mentioned, not records, but with 5-7 days in the 30s, and lows in the Teens, we are just not used to that for so long.

Food for thought:

  • Last time Chattanooga saw 3 days in a row below 32° was Dec 15th 2010.
  • The longest number of days in a row below freezing was 8 back in 1978 and 1885.
  • The COLDEST New Year's Eve ever was 4° in 1880 and for New Year's Day, 2° in 1928.

Average high is 50 and low is 32. We may not see this for 12 + days.
