For the first time this winter, northern Illinois are forecast to see subzero low temperatures.
Temperatures fell from about 30 degrees at midnight to 19 at sunrise today following a storm that delivered just under 2 inches of snow to La Salle-Peru. Motorists who left their cars outside overnight awoke with snow to remove, ice under that and partially frozen car doors.
National Weather Service says temperatures will drop throughout the day, to 7 degrees by 9 p.m. to zero or below by dawn.
Gino Izzi, meteorologist for National Weather Service out of Chicago, said the more northern part of the state had a prolonged, light snow. La Salle County Sheriff's Office reported no major weather-related incidents. The storm left trees flocked and some ice and snow on power lines, but Corn Belt Energy reported no outages. Ameren reported outages in central and eastern Illinois, such as south suburban Chicago, Kankakee and McLean County.
Izzi said it looks like frigid cold air will start to flood in later todayHe said the temperatures will start to fall during the day from the teens to single digits but will most likely stay above zero degrees through sunset.
However, Izzi said a good chunk of northern Illinois and the area will possibly see subzero low temperatures Thursday night and Friday morning is looking pretty cold.
North winds will make it feel exceptionally cold.
“It will likely be the coldest night thus far this winter,” Izzi said.
Izzi said it wouldn’t be out of the question for the area to get -20 or -25 degree wind chills Thursday night or Friday morning, but it looks like the wind chill should be close to the actual air temperature. He said that’s a far cry from the -40 or -60 degree wind chills that the area was facing around this time last year.
“That really makes all the difference in the world,” Izzi said.
But it doesn’t appear that the cold weather will be here to stay for long, Izzi said.
Izzi said this storm system appears to basically be following the typical pattern for this winter, where the area gets a few days of snow or cold temperatures but the mercury will climb to near or above-average temperatures for the area – which are low to mid-30s for average highs and the normal lows being upper teens or 20 degrees.
“So we’re just looking at a couple of days of hard-hitting Chicago type of winter weather,” Izzi said.
In the meantime, Izzi reminded people in the area to limit time spent outdoors, bring pets indoors and dress in warm layers for the next couple of days.
“The less skin you have exposed, the better,” Izzi said.
