The featured chart presents the maximum period with temperatures below freezing based on hourly observations for Des Moines. The longest period this year is only a bit longer than three previous years. There is still plenty of winter season to go and as is shown by the bottom chart, there are longest streaks of the season that get started in February and even March. The forecast has been hinting at a return of winter to the state with chances of snow, but temperatures do not look that cold at least to early next week.
