A winter weather advisory has been issued for most of central Iowa today. Widespread snowfall between two to four inches is expected through this evening. Travel could be hazardous during both the morning and evening commutes along area highways. Those who need to drive should use caution and be ready for rapidly changing road conditions, as well as snow plows and crews working to clear roadways.

Typically, the first inch of snow of the season doesn’t fall until early December, according to 30-year climate averages from the National Weather Service.

Even colder air is expected later this week as well, with daytime highs plummeting into the 20s by Thursday and continuing through the weekend, with wind chill values approaching and even possibly dropping below zero those mornings.
