Near Zero Wind Chills this Week

It's going to get cold and it will happen pretty quickly.  An incoming cold front mid-morning Tuesday will help get rid of the dense fog from Monday.  But don't be surprised if you wake up to dense fog Tuesday morning.

The front comes through mostly dry with Gulf moisture staying in southern Illinois and Indiana.  Low pressure associated with the cold front is currently producing snow over the High Plains and will bring blizzard conditions through Tuesday afternoon.  The heavy snow stays north with only a few flurries possible along the front for Northern Illinois and Southern Wisconsin.

Temperatures will slowly drop by Tuesday evening and really plummet following a strong cold front Wednesday.  A true Arctic air mass arrives Wednesday and Wednesday night - enhanced by moving over a freshly fallen snow pack.

Afternoon wind chills Wednesday could remain in the teens, but in the single digits Thursday and Friday.  Overnight wind chills will come close to zero degrees Thursday and Friday morning.
