Complementing the blog post below about convective initiation in Minnesota, the image above shows the 21-00 UTC hail probability forecast on 10 May 2011. The units are %, and the small 'a' symbols represent observed hail reports. Note the maximum located in western and central Minnesota; as noted in the other post, storms were just forming at 21 UTC, and proceeded to produce severe hail a little east of their initiation point. Additional hail reports occurred later after 00 UTC. Notice also the maximum in eastern Indiana and western Ohio, and the observed reports there.
