May is usually prime tornado weather in Kansas, but most commonly the storms are a scattered along the frontal boundary. On May 15, 1991 things were a little different. On that day, there were 16 tornadoes on the ground for short periods of time, all within 10 miles of Garden City. The amazing part was that no damage was reported. Further north in west central Kansas five small tornadoes formed in Wichita and western Scott counties within a few minutes of each other. Again, these tornadoes were fairly weak, with relatively low damage reports.
