Severe thunderstorms developed along a dryline and moved slowly eastward during the late afternoon and early evening hours of Sunday, May 16th.  Three weak tornadoes were reported resulting in no damage. One tornado appeared to form on the dryline boundary with a sharply tilted condensation funnel stretching to an updraft base approximately 3-4 miles to the east.  This landspout tornado lasted about 2 minutes and crossed Highway 27 south of Sharon Springs, but it did not hit any structures. Numerous reports of golfball to baseball size hail were received from the stronger and more organized supercell storms.  Thunderstorm movement slowed during the evening as some storms backbuilt to the west.  Roads in Gove and extreme southeast Logan counties were reported water covered, with a few section roads still covered with water at noon on the 17th.
