Think it’s too early for snow? O’Hare International Airport recorded a 25-minute snow shower Wednesday afternoon in what the National Weather Service says is very common for this time of year.
The snow began to fall about 1:50 p.m. at the Northwest Side airport, according to meteorologist Bill Nelson. There was no accumulation, and Nelson said the snow was not a big surprise.
Chicago is a bit late on its first trace snowfall, with Oct. 30 being the average date and Sept. 25 being the earliest. The latest trace snowfall happened on Dec. 5, 1999. The latest ever first snowfall -- an inch or more -- happened on Jan. 17, 1899, Nelson said.
There still might be a couple more snowflakes Wednesday evening as another quick system moves out of the region. There’s a 30 percent chance of a mixture of rain and a snow shower Thursday, but still no accumulation, Nelson said.
Eastern Iowa was hit with two inches of snow on Wednesday and 1-1/2 inches of snow was recorded in Mount Carroll in northwest Illinois. In the town of Galena, 1.8 inches of snow fell.
The high on Thursday is expected to reach just 38 degrees with a low overnight of 30.
