What the reports say
Written by National Weather Service staff at the time of the event · public domain
A long track tornado began between Maud and Seminole, before making a north to northeast path of damage across Seminole County. The most extensive damage was to buildings just east of downtown Seminole, as well as near the Seminole Academy. Buildings had the roofs removed from the tornado, and some buildings had exterior walls damaged. As the tornado moved to the northeast, it produced sporadic damage to mainly rural areas northeast of Seminole.
The first damage took the form of broken branches about 5.5 miles west southwest of Seminole and less than a mile east of the Pottawatomie County line. The most intense damage occurred along EW1250 road east of NS3510 Rd where numerous oak trees were snapped and uprooted with large limbs blown downwind. A house in the vicinity lost several courses of shingles which appeared to be higher than the typical quality of shingles. An outbuilding near the residence was leveled and debris blown downwind. Farther east on NS3550 Rd, a small stretch of trees exhibited the most intense damage with roughly 50% of them uprooted or snapped. Finally, the last tree damage occurred one mile southeast of downtown Seminole.
A tornado developed within a squall line just northwest of the town of Konawa and moved east-southeast through the north side of Konawa. Numerous trees were downed and fell into homes creating significant roof and siding damage.
