Well, this September symbolized all I love about the fall in Missouri. We experienced strong thunderstorms, heavy precipitation, plenty of windy days (1 out of 3 days had wind gusts >= 20 mph), and a nice cool-down that brought air as fresh and crisp as the ripe Missouri apples we've been enjoying.
An interesting fact about this September. On Sep. 19, we had a 1.18" rain that put us just over our yearly average of 41.22". Every drop of rain from here out is a surplus, which has been the norm since 2008. Last year, we hit our average yearly precip total on October 7.
Year / Amount Surplus
2010: 2.15" (as of 9/30)
It really was a tale of two seasons, and as I remarked in a previous post, the delineation between summer and fall was quite easy to notice, and can be seen on the graph below. September 24 was a good "first fall" day (although I have no quantitative formula to back that up)
Mean Temp: 69.1°
Maximum: 90° on Sep. 18
Minimum: 46° on Sep. 27
Once again, we have been inundated with heavy precipitation. Those living in flood plains have had a rough three years, and there were many farmers in the area that lost entire fields of crops due to a late-year flood right before harvest time.
