Your location in the state on Monday made a for big difference with how warm it felt. The featured chart displays all Iowa ASOS/AWOS temperature reports for Sunday and Monday along with the hourly range in temperature over the state (red line). This range in temperature briefly touched 50 degrees on Monday as southeastern Iowa was well into the 60s and northwestern Iowa was in the teens! This strong contrast in temperature will make for a wintery mess on Tuesday as conditions will be favorable for freezing rain.
