PEORIA, Ill. -- Temperatures continue to drop across Central Illinois Wednesday night, and the freezing wind chills will pick up during the morning commute.
IDOT and city plows continue to work on clearing the roads, but that becomes more challenging with below zero temperatures.
The Interstates and the main city streets are mostly clear.
Officials said the sun was on their side today -- which is one of the differences with this storm.
The problem Wednesday night is blowing and drifting snow.
Bridges and overpasses are the first areas to freeze.
IDOT officials said the plows will be out as long as they are effective in the cold weather.
"Later in the evening it'll be more of clearing the roads off as opposed to the salt treatments, simply because of the fact that because of the temperatures that salt looses its effectiveness," said Brian Williamsen with IDOT.
City crews will continue plowing residential streets Wednesday night and Thursday morning, but expect them to be snow packed and frozen after this cold spell.
And if the wind continues to blow snow -- crews may have to change that focus to the main roads.
As a reminder, slow down when driving -- even if it looks clear -- because the chances of black ice increases dramatically in this weather.
