Thursday was yet another very muggy day in the state this summer. The featured chart displays the number of hours that the hourly dewpoint temperature was at or above a given threshold for Des Moines for the year to date period. The blue dots represent the long term average since 1973 and the red dots are the 2016 totals. For example at the 70 degree level, we have spent about 33% more hours than average having a dew point at that level or higher.
