Extreme heat was absent this summer

The summer of 2008 was a time with very few episodes of extreme heat in eastern South Dakota, southern Minnesota, northern Iowa and northeast Nebraska.  One measure of this is the lack of days where the high temperature reached at least 90 degrees.  Typically, the maximum temperature will reach 90 degrees between one and three dozen times per year, depending upon the location.  However, this year, with the exception of south central South Dakota, most places reached 90 degrees only a handful of times.  For many locations, the last time there were this few 90 degree days was back in the 1990s.

Below is a list of the number of 90 degree days from several locations across the area.
