Our mostly dry and lack of humidity start to May continued on Tuesday with dew point temperatures in the 30s and lower 40s. The featured chart presents a climatology of daily maximum dew point as calculated by available hourly observations from the Des Moines airport. The 2026 observations are shown as blue dots on the top panel. Each of the daily dots for May is found below a simple long term average for the day. This is in stark contrast to the elevated humidity levels that were common for much of April.
