An extremely warm day on Saturday gave way to something closer to average for mid March on Sunday. The temperature change between the two days was rather dramatic with most of the state ranging between 40 and 50 degrees difference between Saturday and Sunday afternoon. The featured chart presents the largest 24 hour temperature decreases for Spencer (NW Iowa) over an exact 24 hours worth of time. Rewording, this chart does not show the largest difference in temperature over a 24 hour period considering any temperature within that window of time. So the Saturday event was a 51°F degree drop from 4:53 PM on Saturday to Sunday, which is only three degrees below the largest on record for the site.
