Numerous northern Illinois locations received the state’s first measurable snow readings this morning. Historically speaking, that’s late, according to Illinois State Climatologist Trent Ford.

“The climatological first measurable snowfall event in records in northern Illinois is actually mostly in late October,” Ford told the RFD Radio Network®. “As you get closer to central Illinois, it’s mid-November.”

Areas around Rockford, DeKalb, Freeport and the Quad Cities received between 1 and 2 inches. And many parts of northern Illinois were under a winter weather advisory Tuesday morning.

Ford did point out that for snowfall amounts exceeding an inch, Tuesday’s winter weather came about two weeks early, per the National Weather Service in Chicago.

The snow will not be sticking around that long, with temperatures expected to climb back into the 50s by Thanksgiving Day in most of Illinois.

“The forecasted highs on Thanksgiving range from the low 50s up to the 60s in southern Illinois,” Ford said. “So that will take care of any snow that’s still around.”
