Could use some breaks

The featured graphic displays the IEM calculated daily statewide rainfall average since 1 June this year. There has only been one considerable dry period lasting more than just a few days. The recent stretch of weather has not been all that bad thanks to some drier air that worked into the state. Friday looks to return us to "normal" with muggy conditions expected along with storms.

Different ways to measure warmth

18 Aug 2010 05:57 AM

The each sub-chart, blue bars represent a value below average and red bars represent a value above. The bottom chart shows the average difference between the heat index and the air temperature. For this year, the heat index added, on average, more than 4 degrees to the temperature. While this value is the largest shown, the highest air temperature was only 96 degrees and below the average seen in the past 38 years. This year's average temperatures comes in second behind 1983.
