This afternoon (1:19 PM) is the Autumn Equinox, which is the moment when the sun is directly over the equator and denotes the end of the astronomical summer season for the northern hemisphere. The sun will rise due east and set due west today, which has an important impact to vehicle travel as shown by the featured RWIS webcam image from last night near Adair. Since most of Iowa's roads are oriented either north/south or east/west, a good portion of them will experience difficult driving near sunrise and sunset with the sun directly in the line of the roadway. Of course, it isn't just today with these difficulties as the sun's rising and setting is only marginally different than due west and east for a number of weeks surrounding today.
