The featured chart presents the earliest and latest occurrence of a temperature threshold after the first of the year. Many parts of the state have yet to reach 40 degrees, which is approaching a record as shown on the chart for Ames. It is interesting to note how the "latest" line flattens out around 32 F, which basically shows the influence of a deep snowpack in February and early March (much like what is happening this year). This chart also shows that some years, by this date, we have experienced temperatures above 70 degrees. Imagine what that must feel like!
