Autumn Dry Down

As summer 2016 winds down, one noticeable aspect of our weather that will change is that thunderstorms will become less common.  That in turn will also mean that rainfall amounts generally drop.  The wettest month of the year is June with a statewide average rainfall of nearly three and a half inches.   July that average drops to a bit below 3 inches,  August to about 2.25 inches than September to about 1.75 inches.  In other words, from our peak in June, each following month of the growing season the rainfall drops by approximately one-half inch.  This mean that drier weather comes naturally every autumn.  But one other factor also comes into play in the coming weeks, less evaporation with the cooler temperatures, meaning less doesn’t always mean dry.
