Louisville is on the verge of a moderate drought. Keys Arnold with the University of Kentucky’s Agricultural Weather Center says the area is already in a mild drought."Rainwise, it’s been incredibly dry. We’ve actually had a significantly drier year than last year, when at this time we were approaching extreme drought," says Arnold. "The reason the conditions aren’t as bad this year is that we started off with a wet spring."Arnold says 2008 has been Louisville third driest summer on record… it’s the 12th driest in central Kentucky. Rainfall totals for the year are nearly five inches below normal.This year’s drought hasn’t affected crops as dramatically as last year, because it’s coming at harvest-time, instead of the beginning of growing season.
