Severe storms created a large swath of golf ball to baseball size hail across portions of South Central Kansas on Friday, April 8th 2011. Storms first developed over northwest and north-central Oklahoma along a dryline during the early evening hours of April 8th.  With abundant instability, the storms rapidly became severe as they tracked slowly east-northeast. Many of the large hail producing storms that affected South Central Kansas were storms that split from the large eastward moving supercells over northern Oklahoma.
