Snowflakes fell Tuesday afternoon at O’Hare Airport, marking Chicago’s first official snowfall of the season.
Flurries were also reported at Midway Airport and in many west and southwest suburbs in the late morning.
Don’t worry about shoveling, though. The ground is too warm for the flakes to accumulate in most areas, according to Richard Castro, meteorologist with the National Weather Service in Romeoville.
The first hard freeze spread across northern Illinois and northwest Indiana overnight, with the exception of downtown Chicago, the Weather Service said. Temperatures in a few south suburbs, including Aurora and Joliet, dropped into the low to mid 20s.
It’s a bit early for snow in Chicago, but it’s not unprecedented, according to Kevin Birk, weather service meteorologist.
The earliest trace of snow in the Chicago area fell Sept. 25 in both 1942 and 1948. The average date for the first trace is Oct. 30.
The rest of the week is going to be dry and chilly, with highs in the mid to upper 40s.
“There’s no additional chance for snow in the foreseeable future,” Birk said.
