After a windy Monday, windy conditioned continued overnight and into Tuesday before dying down by evening. The featured chart presents IEM computed daily average wind speed and direction for Des Moines so far this month. A simple and smoothed long term average is plotted as well. The perception that Iowa's weather is windier during the spring than previous years can be difficult to prove one way or another. This plot shows less than half of the days plotted above the daily average for wind speed. Wind speeds forecast for the last day of April (today) look to come in at about an average value for the date.
