I was in Grand Rapids, MI in August, 2006 when they shattered the all - time high temperature record by 5 degrees and posted 109 degrees for two
straight days, I was in Chicago during that same heatwave when it was still 101 at Midnight and the fire department was having
to evacuate elderly high rises after a major power
failure, and I was here in Denver when we
set an all - time record high twice in 3 days in June, 2012 with a 106 followed by a 108 reading, which was 5 degrees hotter than the previous record high before 2012 too.
