Thus far year-to-date Knoxville has had 24.5 inches of precipitation. The normal amount is 37.5 inches. October is typically one of the driest months of the year.

THE WINTER OUTLOOK (AND THIS COMES WITH THE USUAL DISCLAIMERS ABOUT ACCURACY) IS FOR A WARM AND DRY ONE, AGAIN.

Out of curiosity, does anyone know what the driest year on record is? I Googled, but did not find.
