These states are all over so I couldn't pick a region but I guess thunderstorms apply since it's about rainfall:
Drought to Deluge: Ten Rainfall Winners

Georgia: Macon
Macon, Ga.
Jan. 1 - June 10, 2013 35.49"
Jan. 1 - June 10, 2012 12.77"
All of 2012 32.41"
A year ago, Macon was sitting in the midst of an "exceptional" level-four drought the worst possible category in the U.S. Drought Monitor report with less than 13 inches of rain in the bucket for the year by June 10.
It's been quite the turnaround in 2013. Of all the long-term observation sites we looked at nationwide, Macon has had the biggest improvement in absolute terms over 22 inches more rain year-to-date than a year ago. The entire state of Georgia is now drought-free.
In fact, Macon has already blown past the rainfall total for all of last year and added three inches of rain on top of that with the year less than half over! As you'll see on the coming pages, Macon is far from alone in that club.
