The first widespread freeze of the season hit the area overnight and if you’re in the city or south suburbs, you may see the first snowflakes fall Tuesday.
The first hard freeze spread across northern Illinois and northwest Indiana overnight, with the exception of downtown Chicago, said Kevin Birk, a meteorologist with the National Weather Service in Romeoville. Temperatures in a few south suburbs, including Aurora and Joliet, dropped into the low to mid 20s.
The chance for rain or a few snowflakes in the city Tuesday afternoon is between 40 and 50 percent, Birk said.
“Here in Chicago the chances are not the best, and the reason is it looks like the main track of the system is going to take the precipitation to the south of the area,” Birk said.
It’s a bit early for snowfall in Chicago, but it’s not unprecedented, Birk said.
The rest of the week is going to be dry and chilly, with high temperatures in the mid to upper 40s.
“There’s no additional chance for snow in the foreseeable future,” Birk said.
