EF0 tornado in Limestone County, Texas

The tornado began on the southwest side of Groesbeck along the west side of S State Highway 114 where damage to a small barn resulted in the removal of the roof. As the tornado moved northeast it caused a narrow path of damage along Private Road 5401 with a few structures damaged including the lift and removal of a metal roof from a manufactured home and damage to a few metal shelters and a carport. The tornado then crossed Highway 14 N just north of Groesbeck causing damage to several trees as the tornado tracked toward Shiloh. As the tornado reached County Road 431 and FM 39 it lifted/wrapped a large anchored farm outbuilding against a tree. After crossing FM 39 the tornado partially removed the roof of a manufactured home before it is believed to have lifted. Maximum estimated winds were 85 mph.

A strong shortwave trough aided in the development of scattered to numerous thunderstorms during the late morning, afternoon, and evening hours of March 21. Thunderstorms initially fired along a dryline, many of which became severe, and some of which produced strong tornadoes. A total of 17 tornadoes were confirmed by storm survey teams, the strongest of which was the EF-3 Jacksboro tornado. One death occurred in a tornado in Grayson County near the Red River.
