A frontal boundary was draped over Iowa Friday evening and into Saturday. The featured chart displays a time series of air temperature and wind direction reports from a weather station located on the Agronomy Hall building at ISU. It is interesting to notice how the front was waffling back and forth over the area for the evening. The sign of this movement can be seen by the change in wind direction and air temperature. The switch of the wind to the northwest brought cooler temperatures and the swing back to southeast brought warmer temperatures.
