How Hot Did It Get Last Week?

The persistent ridge over the middle of the U.S. meandered into the Ohio Valley Thursday and Friday, providing another round of oppressive heat.  Maximum heat index values for the period from Tuesday afternoon through Saturday evening ranged from 107 degrees over the Bluegrass and Lake Cumberland region to 117 degrees in Munfordville.  The map below indicates the maximum heat index at multiple cities across our forecast area of Southern Indiana and Central Kentucky.

How does this heat compare to the oppressive heat from back on July 11-12?  The map below indicates what the maximum heat indices were for those days.  In general, peak values were 2-7 degrees cooler with this week's heat.  The prolonged nature of the heat, over 5 days, made it just as dangerous however.
