Here's a look at our maximum heat index values from the weekend, for today, and for the rest of the week!  Yikes!  Below the picture is a heat index calculator that I used to make this graphic.  All you do is take the high temperature, and input the dew point temperature, then hit "calculate".

Currently, this July stands as the 5th hottest on record (this after the hottest June on record).   The average temperature (high + low divided by 2) so far is 82.2 degrees, the hottest average is 84.2 in 1092, 2nd = 83.3 in 1936, 3rd = 82.5 in 1921, 4th = 82.4 in 1934 (notice all of the top 5 except this year are from the early 1900s).  The average is 4.2 degrees above average.  Our average high for this time of year is 87-88 degrees - but again, we've been well above that this July.

The heat wave pattern basically began on May 23rd with our first 90 degree day.  We have had a couple of short "cool-downs", but have generally been hot since late May, nearly two months now.
