Chicago weather radar: Ice Storm Warning issued for parts of area, thousands without power

CHICAGO (WLS) — A winter weather storm moved into the Chicago area Wednesday, bringing a mix of ice and freezing rain to the area.

A Winter Weather Advisory has been issued by the National Weather Service for northern Cook, Lake, Kane and DeKalb counties until 6 a.m. Thursday.

An Ice Storm Warning has been issued for McHenry County from until 6 a.m. Thursday.

Parts of southern Wisconsin are under an Ice Storm Warning from until noon Thursday.

ComEd said as of 5 p.m., there are 30,000 customers without power systemwide. Crews are working to restore power to customers as quickly as possible.

Racine County has issued a declaration of emergency because of the weather conditions, with all employees being told to go home. The sheriff’s office is advising people to go stay off the roads.

ABC7 Meteorologist Larry Mowry said there is concern for ice accumulation in the far north suburbs, mainly in parts of Lake and McHenry counties. However, the heavier the rain that falls, the less likely it will be to ice up.

As of 3:30 p.m., there have been ice reports of .10 to .20 inches on elevated surfaces like trees and street signs in parts of Lake, McHenry, DuPage, Kane, DeKalb and northern Cook counties, Mowry said.

Temperatures have held in the low 30s, and with the warm-ish ground most roads have remained wet and not icy. After sundown, roads may become impacted by ice.

Elsewhere in the Chicago area, heavy rain will be likely with 1 to 2 inches possible. The highest totals will be southeast of the I-55 corridor, and you might even hear some rumbles of thunder.

The first round of precipitation started early Wednesday in the south suburbs, and was expected to expand into the western suburbs and city throughout the morning, primarily as rain. Gusty winds are also expected.

Some localized flooding is possible due to heavy downpours.

The precipitation will taper off later Wednesday evening and mostly end overnight.

By contrast, in downstate Illinois temperatures are in the 70s with a tornado watch in effect, Mowry said.

Crews in McHenry County have prepared for the changing conditions. Trucks loaded up on salt Wednesday morning and hit the ground quickly to prepare for the wet weather.

“We’re going to get trucks out on the street and we’re going to get a light coating of salt down before the temperature drops and then we’ll be here throughout the evening to put salt down as needed,” public works director Ryan McDillon.

The scene was much the same in Huntley, and in Elgin the cars at one dealership were covered with a layer of ice.

“If you’re not sure-footed, you shouldn’t go out today,” advised Elgin resident Bob Selle.

With the mild winter so far, there is plenty of salt to go around too, so crews will work thru the evening to keep the streets from freezing over.

In Crystal Lake, ground temperatures are still relatively warm, but they began salting roads this morning hoping to get ahead of the storm. It’s trickier to deal with weather like today’s than a typical snow storm.

“Freezing rain is worse than snow because the rain dissolves the salt so quickly so we have to be out there more often and put down more material,” said Crystal Lake Public Works Director Mike Magnuson.

Temperatures will warm Wednesday night into Thursday, with temps close to 50 degrees Thursday morning before falling again the afternoon.

Friday will be a cold, blustery day with a high of 28 degrees. A few flurries are possible Friday night.
