The past three days have been plenty windy as strong northwest flow has persisted. The featured chart presents the daily average wind speed and direction for Des Moines Airport this month. Winds during the daytime are much stronger than at night as the sun promotes lower atmosphere mixing during the day, which brings higher speed air down to the ground where we live! The climatology for April is around 10-11 MPH, so this year is not much windier than average.
