Another chilly start to the day with patchy morning frost. Then we're looking at mostly sunny and cool conditions this afternoon. Sunday night was a killing frost to our NW, so the growing season is officially over for Madison, Union, Logan, Hardin and Champaign counties. No further frost or freeze warnings will be issued in those counties. There's a chance for showers late tonight and tomorrow, followed by another round of very chilly temperatures Thursday morning. Milder weather should return heading into the weekend, with another chance for showers by Sunday.
