Shift to eastern Colorado 18 May 2011

19/0100Z: Supercells over Crowley and Kiowa counties.  Kiowa county storm still shows strong/deep mesocyclone with attendant large hail/damaging hail risk. There was a brief land spout reported with storm early in life cycle, but appears that it has evolved into a more HP-type storm with decreased tornado potential. 0-2km Az-shear has weakened the past 30 minutes with this HP transition. Although MESH is indicating less-than-severe-size hail, there are reports of 1″ to 1.75″ hail with the Kiowa county storm. Hgt 50dbz above -20C and estimated dbz at -20C would support the larger hail.  kbrown
