Sub-zero wind chills return tonight, with a Wind Chill Advisory north and east of Indianapolis from 3am until 9am. Chills will drop to around 15 below, with winds gusting to 25 mph. Winds will ease during the day Wednesday, but chills probably won’t get above zero until afternoon. Winds will get gusty again Wednesday night with the passage of yet another cold front.
Even colder air will pour in behind that front Thursday and Thursday night.
The focus shifts to storms Friday night into the weekend.
