Overview
Two overnight tornadoes that occurred during the early morning hours Wednesday have been confirmed. A relatively rare meteorological setup provided an environment favorable for overnight tornadoes in the strongest storms. One particular supercell moved from Armstrong County through Donley County and into Gray County spawning these two EF1 tornadoes and dropping tennis ball sized hail in western Donley County.
