After some hot and muggy weather to start off the month, the past week to ten days have seen rather pleasant August weather with comfortable temperatures and dew points. The featured chart presents August dew point percentiles for Ames. The top panel shows the percentile climatology by hour and needs some plotting help to make it more useful! The bottom panel is more interesting and displays the hourly dew point percentile values this year during August. The percentiles are computed for each hour of the month. The side panel on the bottom plot shows a histogram of these values which gives an indication of the amount of time Ames has spent at a given decile range this month. So the moral of the story here is that we have majority of time this month below the 50th percentile for dew point.
