Record Cool August Occurres for portions of the Ozarks

Top 10 Coolest Summer Season at Vichy/Rolla

A rather cool weather pattern persisted for most of the 2009 summer season. With the exception of a 2 week period in June, most of the temperature readings this summer were  cooler than you would expect. There have been several record lows set this summer along with some record cool daily high temperatures.

August was no exception as average monthly temperatures ran between 2 and 4 degrees below normal for locations across the Ozarks. Many locations experienced daily highs in the low 70's this month. While this made for a comfortable summer, it's not normal. To the contrary, it's rather chilly for this time of year. Meteorological summer runs from June through August, and Vichy/Rolla, Joplin and West Plains finished with top ten coolest August's and Vichy/Rolla finished the season with a top ten coolest summer.

Below are the Average Monthly Temperatures for August 2009 and where they stand compared to the top ten coolest Augusts on record.
