Recent Windy Days

19 Mar 2025 05:30 AM
Tuesday was another very pleasant March day with high temperatures again above average for nearly all of Iowa. Wednesday will see a dramatic change with a return of high winds and blizzard conditions over portions of the state. Wind gusts will certainly exceed 40 MPH and make for another recent such windy day. The featured chart presents the number of days for Des Moines between 18 Feb and 18 Mar with a daily wind gust of at least 40 MPH. The six days over this period ties 2002 and 2019 for the most. This type of chart would be taken with a grain of salt as long term wind gust observations are tricky due to observational changes and instrumentation changes. While data does exist for Des Moines prior to 1973 (the selected start of this chart), that data can be difficult to resolve if gusts were routinely reported and/or the averaging period for such values.
