Event Summary

Severe thunderstorms on the evening of 19 May 2010 produced flooding, hail, wind damage and a few tornadoes in eastern Oklahoma.  

Survey teams from the National Weather Service Office in Tulsa investigated storm paths in Pawnee County... Creek County ... and Tulsa Countiesy and Muskogee County.  Other locations could also be examined.

On May 21, 2010, a survery team examined the area northwest of Glenpool where FAA Terminal Doppler Radar data showed a significant low-level rotation.  Some tree damage was found, two privacy fences were damages and two homes lost a few shingles.  But so far ther is not enough of a pattern to classify the damage as tornadic.
