On October 12th, a strong low pressure system was moving across the western United States. A strong upper level disturbance, in addition to increasing instability in wind shear, produced an environment favorable for high winds and severe weather. High winds moved across western Kansas around mid day producing up to 60 mph winds that blew over 8 semi trucks on Interstate 70 in Gove County and caused a slight reduction in visibility due to blowing dust in Sherman County. Initially, storms developed in warm unstable air across northwest Kansas. These storms were supercellular in nature, but struggled to fully develop because the instability was overcome by the substantial wind shear. However, additional storms developed along a dryline in eastern Colorado, spreading east across northwestern Kansas throughout the evening hours. These storms produced the reports of up to quarter sized hail, the tornado in Sharon Springs, and up to 100 mph winds gusts that caused damage in Logan and Gove counties.
