SPRINGFIELD, Ill. (WICS) — After a brief lull in the weather on Friday, now another winter storm is setting its sights on central Illinois. Come Saturday, our next round of Winter is set to arrive. A new weather maker sweeps across the Upper Midwest, causing more snow to develop by mid-morning on Saturday. A Winter Weather Advisory has been issued from 7AM Saturday through 8 PM Saturday evening. The snow will pick up intensity by late-morning and last through the afternoon into the early evening hours before ending. This new weather system will follow a path very similar to the previous storm system and spread a swath of moderate to locally heavy snow. Before the snow wraps up Saturday evening, expect another 2″-4″ for much of central Illinois, with afternoon high temperatures bitterly cold in the mid-teens.

But the worst blast of cold air comes in Saturday evening into Sunday. Frigid Arctic air surges down from Canada causing temperatures to really tumble, driving in the coldest weather we’ve had in a long time and certainly the coldest so far this season. A Cold Weather Advisory is issued from 8 PM Saturday through Noon on Sunday. Sunday morning will be dangerously cold with wind chills around 20 to 25 BELOW ZERO. With wind chills this extreme, it doesn’t take long to suffer from frostbite or hypothermia. Please stay inside to keep warm, but if you do need to venture out, limit the time you spend outdoors, and make sure to cover up all exposed skin by wearing a hat, scarf, and gloves. Sunday afternoon features lots of sunshine, but despite the sunshine, temperatures will be brutally cold and frigid with high temperatures stuck in the low single numbers while wind chills remain well below zero.

Expect more extremely chilly weather on Monday with wind chills still ranging from 5 to 15 BELOW ZERO in the morning and afternoon highs only reaching into the 20s. Then temperatures will finally start to warm up, and we should climb out of the deep freeze with highs in the mid to upper 30s on Tuesday.
