September 90+ Days

Posted: 27 Sep 2017 05:34 AM

The cold front on Monday gave us a break from the very warm conditions for late September. For Des Moines, five days this month were 90+ degrees for high temperature. The featured chart displays the number of 90+ degree days for September. While having five days is double the long term average, there have been plenty of recent years with as many days and the record number of sixteen days is triple of 2017. It remains to be see if we will hit 90 degrees again this fall, but very warm weather looks possible was we start off October.

Good = 9
Bad = 0
