Snow Squalls, 45 MPH Winds For Halloween In Illinois

ILLINOIS — Trick or treaters should expect to wear multiple layers on Halloween, as temps in the 20 and snow showers are expected, according to the National Weather Service.

The weather service said "a strong disturbance" will bring bursts of snow and possibly even snow squalls on Tuesday. Travel conditions could be impacted on Tuesday morning, especially if snow arrives before the sun rises.

Snow squalls are short, intense bursts of heavy snow that can lead to poor visibility and are sometimes accompanied by gusty winds, the National Weather Service said.

The highest coverage of snow will be north of Interstate 80, the weather service said.

Snow showers and possible squalls are possible midday on Tuesday and into the afternoon. Visibility could be brought down to under one mile as gusts up to 45 mph are possible in the strongest squalls, the weather service said.

You could see spotty or slushy accumulations on grassy surfaces Tuesday afternoon.

Temperatures on Halloween will be between 30 and 35 degrees, but wind chill will be between 18 and 25 degrees.

Snow showers should end early evening on Tuesday for most of the area, the weather service said.
