REPORT: May 13, 2009

SHORT: Nice birthday chase. Got on a brief landspout west of Watonga. Well defined funnel with intense ground circulation. Saw some good structure and then came into Anadarko during the tornado/macroburst watching multiple power flashes and had to take cover on the west side of town while sitting through insane winds! Widespread major damage in town. Took us forever to get through town because of downed trees, powerlines, sheet metal, roofs, and just about everything else. A few pic of the landspout funnel and associated ground circulation...
