We are in for another winter storm in the Heart of Illinois. It may have been a nice start to our Friday, but things are really going to change later today. A Winter Weather Advisory will go into effect today at noon until 6 AM for the entire area.
Here's a general timeline of impacts:
This morning will be dry until we get into the early afternoon hours when snow will move into areas West of the Illinois River.
The snow will continue to be moderate to heavy as we head into the evening commute. With how cold it has been the past few days, snow should start to stick as soon as it starts falling. This could lead to snow packed and slick roads this afternoon & evening.
Later in the evening, we'll see a warm front approach the area and the snow will change to freezing rain as early as 8 PM. This could give us between 0.1 to 0.2 inches of ice on top of the snow. Prepare for slick roads during the early evening hours.
As the system continues to pull to the North of us, we'll see the freezing rain and sleet turn into all rain as temperatures continue to rise above freezing. In addition, winds will pick up out of the South gusting to 35 mph at times.
The rain will subside as we head towards daybreak. Total overnight rainfall could be up to an inch in some areas. Then as we head into tomorrow morning, an arctic cold front will bring rapidly falling temperatures. Any water left on the road from Friday nights rain, could freeze over and create an issue with ice.
Once the arctic front passes, temperatures are going to plummet all day Saturday and Saturday night and by the time you're waking up on Sunday. Morning temperatures will be in the low single digits but wind chills will be well below zero.
Stay warm everyone! We are in for a doozy of a storm.
