Daily Feature

2025 1+ Sigma Days
Date: 06 Jan 05:30 AM
Votes: Good: 8   Bad: 0 Abstain: 0

Continuing the theme of looking back on 2025, today's featured chart computes the percentage of days each year with a high temperature of at least one standard deviation above average for Ames. The statistics for each year are computed over the present day period of record for the site, so that is a caveat to the plot. The usage of a standard deviation helps to normalize the departures as a day ten degrees above average during the summer is less frequent than during the winter, for example. That aside, last year comes in the top ten for having the largest percentage of such above average. The other years include some notable years during the Dust Bowl and also the drought year of 2012. The flood year of 1993 leads the bottom ten with a remarkable low count of such warm days!
