The coldest weather to date has arrived for Iowa with the NWS issuing Frost Advisories for much of western Iowa. The featured map presents the yearly average frequency of frost advisories since 2006. This alert is typically only issued once or twice in the fall season, but can be issued in the spring for late season cold. Every county is shown above 1 alert per year, except Wayne County. There likely isn't a physical reason for this, but a quirk of how this product is issued by the NWS Offices covering the state. There was no early freeze in the state this year, which was needed to help get crops to maturity.
