I relied greatly on Thomas Grazulis’ entry in his book Significant Tornadoes for this event.
The SPC has a path length of only 0.1 miles in Adair County. Grazulis lists a 10-mile track from Cass County into Adair County. He denotes the tornado began 5 miles SW of Adair and moved ENE passing 4 miles south of town. Using this information, I estimated coordinates for our map below. The SPC only lists a beginning latitude and longitude. (41.45 / -94.70).
The Climatological Data National Summary states this was the first in a family of 4 tornadoes. They mention the tornado started 4 1/2 miles SW of Adair. They give no endpoint.
Four farms were destroyed. Per Grazulis, “Virtually nothing was left on the site of a farm near the county border. Heavy machinery was thrown over 100 yards, and boards were driven into trees.”
