Frozen start to 2025

For some parts of the state, the first eight days of 2025 have been below freezing. One such example is Mason City. The featured chart presents the number of days during the first eight days of each year that the high temperature was above 32°F. The zero for 2025 is the first since 2010, but roughly 1/4 of the years on record have had a similar start to this year. While this plot doesn't correlate these numbers with snow depth, a manual calculation shows that nearly all of those years with six to eight days had no snow cover and vice versa, most years with zero had snow cover.
