Dangerous cold temperatures are back once again across Illinois as the up and down winter continues.  Temps plummeted overnight, dropping nearly 40 degrees in the span of eight hours in some spots, and wind chills are creating potentially deadly conditions outside especially in the northern half of the state.

The descent will continue throughout the day today, with temperatures here topping out around 10 degrees this afternoon and northern Illinois staying below zero for upward of 36 hours.  The high yesterday was 60 here in the Riverbend.
