 Brief Description: EVENT NARRATIVE: The seventh tornado formed in northeast Edmunds county and tracked northeast. The tornado took off sections from the roof of a barn. The tornado then tracked through primarily crop and pasture land to near Deerfield Colony and into southeast Mcpherson county. Sporadic tree damage was observed along the tornado path with many wooden power poles completely sheared off. Wind speeds with this tornado were estimated between 111 and 120 mph. EPISODE NARRATIVE: Several supercell thunderstorms developed along a very strong warm front and produced nine tornadoes from Akaska to Bowdle to Hecla. The largest of the tornadoes was an EF4 tornado which occurred near Bowdle. This tornado produced devastating damage in the Bowdle area. The other tornadoes ranged from EF0 to EF2 and caused extensive tree and building damage. Nearly one-hundred power poles were downed along with several high line towers leaving nearly a thousand customers without power.
