Winter weather has officially arrived, bringing with it plunging temperatures Thursday and up to 5 inches of snow on Friday.
Although there's just a 20 percent chance of snow before noon in today, temps are expected to dip below 10 degrees by 4 p.m., with wind chills as low -5, according to the National Weather Service. Friday comes with a 90 percent chance of snow with accumulation expected to be between 3 and 5 inches.
A winter storm watch is in effect from Friday morning through Friday evening in a six-county area, including Cook.
Commuters should plan for longer travel times than usual, as much of the snow is expected to fall during Friday's afternoon rush. Roadways may also become slick Thursday with the sharp plunge in temperatures.
