Very little cold
Posted: 06 Nov 2026 05:30 AM, Views: 227Besides the continued wet weather that has plagued the fall harvest season, the other major story has been the lack of cold temperatures. The featured map presents the fall season to date (ending Thursday) minimum low temperature for the long term climate sites within Iowa. These maps tend to be a bit noisy with local micro-climates heavily influencing low temperatures early in the cold season. The map generally shows much of southeastern Iowa yet to experience a freezing temperature. Such temperatures appear possible Saturday morning, but milder temperatures are expected to quickly return with overnight lows remaining well above freezing.
