With cold air back in the state for Tuesday and the rest of this week, it is good to provide some optimism for warmer temperatures. The featured chart displays three climatologies for daily temperature for Ames. Two of them are smoothed for the standard climate period of 30 years and the bars represent the simple arithmetic average based on period of record data. It is interesting that while the smoothed climatology show average temperatures rising by the middle of this month, the period of record data continues in the downward direction.
