The National Weather Service has an urgent winter weather message for Illinois counties of Kankakee, Livingston, Iroquois, Ford along with Lake, Porter, Newton, Jasper and Benton counties in Indiana.
It says that when its winter storm warning expires at midnight (CST), a wind chill warning remains in effect until noon (CST) Tuesday.
The Weather Service forecasts that even though snow will end from west to east tonight, blowing and drifting snow will continue through the night.
It says accumulations of additional snowfall of up to 1 inch are likely, with 2 to 4 inches possible tonight across Porter County in Northwest Indiana.
The Weather Service says total snowfall accumulations from this storm should be 8 to 16 inches with the highest amounts in far Northwest Indiana.
The Service says strong northerly wind are causing “significant blowing and drifting snow” which will cause near white-out blizzard conditions at times until it dissipates.
Its wind chill warning involves “dangerously cold wind chills” tonight through Tuesday morning, with the most extreme wind chills late tonight through tomorrow afternoon, then early Tuesday morning.
It forecasts wind chills 30 below zero through midday Tuesday with a period of 40 below to 50 below zero late tonight through tomorrow afternoon and again early Tuesday morning, saying, “These forecast wind chills are the lowest in nearly 20 years.”
A wind chill warning gets issued when wind combines with very cold air to cause dangerously low wind chill values that can result in frost bite, hypothermia or death if precautions are not taken, including pets and other animals.
The Weather Service warns that frost bite and hypothermia will occur in minutes with the forecast wind chills, and death will occur if precautions are not taken when being outside.
It expects temperature to reach 12 below to 20 below zero tonight and tomorrow night, with record cold highs of 8 below to 15 below zero tomorrow, with strong northwest winds blowing and drifting snow through tomorrow.
The winter storm warning through midnight means significant amounts of snow are occurring with strong winds, making travel very hazardous or impossible.
