This picture is worth a thousand words. It is a chart showing the high and low temperatures at my weather station for the past month. Without expanding the picture one story is obvious, it is getting warmer as you move from left to right. What is personally interesting is what you see in the last six day's data: the high is over 100 degrees for six days in a row. In 35+ years of being an amateur meteorologist, I've never experienced six days in a row where the high temperature exceeded 100 degrees.

Wow, that is HOT !
