Extremely Cold Air - Snow Chances This Week

EXTREMELY COLD TEMPERATURES...

The arctic air continues to move into the Hoosier state. The temperatures over the next few days will be the coldest in two years, and a couple of mornings will be dangerously cold factoring in wind chills. How do wind chills as low as 15 below zero sound? That is certainly possible by tomorrow evening and night. Temperatures tonight fall into the teens, stay there all day tomorrow, then the combo of clear skies and lighter winds set the stage for the extreme arctic cold Tuesday morning. Lows could fall close to zero degrees. Highs on Tuesday will slowly make it into the teens, but back in the single digits Tuesday night. Get ready to put your furnace in over-drive!! 

SNOW CHANCES...

While flurries are possible off and on between now and Tuesday night, accumulations will be little to none, and shouldn't  cause any travel problems. 

The area with the biggest snow chance will be extreme northern Indiana. The lake-effect snow machine will get going, and some areas like South Bend, Goshen and points northward could see several inches if the bands set-up just right. 


Somewhat milder air should try to work in during the day Wednesday, with more tolerable high temperatures in the 20's. This now leads to the fun part of the forecast. The potential for accumulating snow! 

A storm system is brewing Thursday into Friday. This has been on the models for a few days now, but the models are struggling with the track, and how much cold air. The models are notorious for pushing out arctic air masses too quick. I think the models will trend a bit colder and farther south with the track as we get closer. This storm has the potential to bring ice, and several inches of snow to the state. The current model runs would suggest it would get warm enough for a rain/snow/ice mix on Thursday, then a switch to all snow overnight Thursday into Friday. Here is the area where I think the highest chances are for a decent snowfall for now. That may need pushed south or even north a bit as we get closer. 

I will have updates on that system over the next few days. It needs to be watched CLOSELY. Behind that system, another decent shot of cold air appears likely to begin next weekend. 

Thanks for reading. Have a great night, God bless.
