Another complex winter weather set-up is expected this week. Some ingredients are in place for major snowfall totals, but others are significantly lacking... the forecast is tricky and I doubt the snow totals will meet your expectations.. This must be how Bobo feels......

Back to weather: the cold is real, and is definitely the most widespread, significant part of the forecast. Everyone should be ready for that. However, the snow is the fun part, so let's jump into it...

Also, just a heads up, my time will be limited here this week... I have been battling the flu for the last 3-4 days and I'm exhausted. I will say that I started feeling better watching that "questionable character" Jalen Carter and Nolan Smith wreak havoc today.... unfortunately, I was pulling for the Rams... but that was a no-lose situation for the Dawgs. Alright, back to weather:

Important Note:​

I will likely be updating this on Monday and even Tuesday morning, with significant changes possible. That's just the fact. This is a very complicated set-up and likely to change.

Key Messages Across All Impacted Areas

  • Travel Impact: Snow, sleet, and freezing rain will create hazardous travel conditions starting Tuesday afternoon, continuing into Wednesday morning. Even light accumulations could significantly impact roadways.
  • Cold Temperatures (The bigger story): Arctic air will maintain below-freezing temperatures for much of the region. Combined with gusty winds, wind chills will be in the teens or single digits Tuesday night. This will be dangerously cold and a rare Extreme Cold Warning has been issued across North Georgia for Sunday night into Monday morning.
  • Snow lovers won't love this forecast.
  • Snow lovers who also want a change at OC will be very happy in a few days anyways. Ok, back to weather:

Northwest Georgia

Example Cities: Rome, Dalton, Ellijay, Trenton, LaFayette

Key Impacts: Little to no impact. Perhaps some flurries. You will want to take precautions for the extreme cold temperatures though. Be a good neighbor and check on any elderly folks who may live around you. Sometimes heating systems struggle to keep up with this level of cold air, which could quickly become dangerous.. Maybe consider giving those folks a backup option, if you are able.

Important Notes for All Areas

  • Extreme Cold: Wind chills near or below zero are expected Tuesday night into Wednesday morning. Take precautions for pets, pipes, plants, and vulnerable populations.
  • Refreezing Risks: Temperatures will remain below freezing overnight into Wednesday, increasing the likelihood of black ice.
  • Preparations: Any liquid on the roads anywhere across Georgia will freeze each night next week. Be careful every morning commute
Like I said, I will likely update this over the coming days. As I am finishing typing this out, I still feel rather low confidence level. Feel free to drop any questions and I will get back to you as soon as possible
