In the afternoon of April 8th, 2021, a singular thunderstorm developed in Comanche County, but quickly gained strength and began to produce large hail in northern Comanche County by 5pm. The thunderstorm split over Erath County at around 5:30pm as it progressed eastward. The weaker cell split to the north of the town of Hico and then eventually just south of Dallas before dying. The other cell moved south towards the Town of Waco strengthening into a long-lived Severe Thunderstorm dropping large hail as it went. It continued on this trajectory approaching the Burleson/Brazos County border around 8:30pm. The first Severe Thunderstorm Warning was issued at 8:39pm CDT for portions of Burleson, Brazos, and Grimes counties with the first report of hail falling in Brazos County at 8:50pm. The most significant hail in our area fell in Bryan-College Station area between 9:00 - 9:30pm CST where 1" to 2.75" (the size from a quarter to a baseball) fell. A Tornado Warning was issued as the storm moved over the College Station area due to radar-indicated circulation, though no tornado has been confirmed for this storm at the writing of this summary. The storm continued its southeastward motion into southern Grimes County before eventually dissipating in western Montgomery County at around 10:30pm CDT.
