Last week was quite wet for central and eastern Kentucky, where 2 to 5 inches of rain fell across many locations east of Interstate 65.

This map shows 7-day rainfall totals ending Monday. The area that received at least 2 inches of rainfall covers most of the eastern third of the nation!

Normal 7-day rain totals at this time of year are less than 1 inch.
