The fall season is officially here in Iowa eventhough the actual weather feels more like the muggy days of summer. The featured map presents the three week change in climatological average high temperature over the US. The map nicely shows where fall makes its fastest progression (high plains and mountain regions) this time of year. Places like Florida are only slightly affected thanks to the moderating effects of being surrounded by warm water. The corn belt makes a conspicuous appearance in this plot as an area cooling slower than areas to its north and west.
