The National Weather Service says the first snow of the season is expected Tuesday on Halloween in the Chicagoland area alongside blustery winds and cold temperatures.
“This isn’t a trick! Halloween 2023 will be marked by cold temperatures, blustery northwest winds, and snow showers,” the National Weather Service (NWS) said Monday.
The weather service urged those participating in trick-or-treating to bundle up in multiple layers.
Periods of snow and even some snow squalls are expected.
The NWS said snow will develop in the morning with the highest coverage north of Interstate 80.
The snow could lead to some slick travel during the morning commute, especially on elevated surfaces, according to the NWS.
Gusty snow showers and squalls are expected to develop midday and into the afternoon Tuesday, which will lead to “brief sharp” visibility reductions.
The NWS said temperatures Tuesday evening are expected to be 30-35 degrees with wind chills making the feels like temperature 18-25 degrees.
Winds are expected to be 15 mph with gusts up to 35 mph.
Lake effect snow is expected Tuesday night into Wednesday. Quick accumulations up to one inch are possible in Illinois and one to four inches are possible in parts of northwest Indiana.
