November 9, 1926: A devasting F3 tornado moved northeast from near the Potomac River to La Plata. It ended near Cedarville. 17 were killed, 14 of which occurred at a small school near La Plata. Per Grazulis, the school “was lifted, thrown into a grove of trees, and blown apart. The body of one child was found in a tree 300 feet away. A page from the school ledger was found near Bowie, 36 miles to the north-northeast.”
