Severe Weather of May 21, 2010

May 21, 2010

Storms formed in the Wabash Valley on the afternoon of May 21, 2010. These storms slowly developed to the southeast and crossed much of southern Indiana and northern Kentucky. Strong winds from different directions in the middle and upper parts of the atmosphere caused many of the storms to rotate, while winds near the surface were relatively weak. As a result, many wall clouds and possibly several funnel clouds formed, and one tornado did touch down in eastern Breckinridge and northwest Hardin counties. (What is a wall cloud?)

We at NWS Louisville received many photos of these spectacular looking storms. Thank you to everyone who sent us these pictures to share! (If you have a photo or video to share, fell free to send it to us!)
