The storm system that is bringing big snow and ice to the south will also spread light snow into Indiana due to the merging of two storm systems over eastern Kentucky.
We seem to be in a pattern where we will see a storm system every weekend from now through January 25th.
The polar vortex will relax for three days before it reloads again. We should be above freezing from January 15 -17. After that, it gets cold again.
After that, the polar vortex eases again during the first week of February. There are hints that it will try and make a comeback by Valentines Day.
I don't like it but the National Weather Service has removed the "Windchill Advisory" and replaced it with a "Cold Weather Advisory". I think phrase "cold weather advisory" is fairly relative. I think the phrase "windchill advisory" automatically informs people to bundle up and wear extra layers and not to stay outside too long. That's just me though. In addition to that, the NWS has changed a lot of their definitions. If you would like to see all of them, you see them at:

Here is an example of the new "Cold Weather Advisory"
