OTD in 1967 one of the worst tornado outbreaks in Minnesota history struck the Albert Lea area. 21 tornadoes touched down in IA/MN/SD. It had what was likely one of the most extreme tornado environments in MN history. #mnwx #wxtwitter #wxhistory (1/6)

The small warm sector helped limit the coverage of the tornado outbreak but inside that warm sector, the supercells were prolific significant tornado producers. 8 were F2s, 2 were F3s and 3 were F4s. (2/6)

The first F4 tore through the town of Waseca MN, destroying 16 homes and leveling 6 of these homes. Sadly 6 people were killed by this tornado. (3/6)

The 2nd F4 tore across rural areas near Northwood IA/Myrtle MN. 10 farms were destroyed with 3 being leveled in near-F5 intensity according to Grazulis. This event might have been two tornadoes due to time conflicts. (4/6)

The 3rd F4 tore through Albert Lea and rural areas. 10 homes were leveled in town while 6 farms were leveled outside of town. 5 people were killed by this tornado. (5/6)

A killer F3 tore through farms near Alden MN. At the start of the path, there was near-F4 damage. 2 people were killed. (6/6)
