Four supercells produced a record setting hail event and one tornado across parts of North Texas. Two of the four supercells tracked through Dallas County causing over a billion dollars in hail damage. The hail in Dallas County ranged in sizes up to 3 in diameter. In many areas, the hail lasted for at least 30 minutes. Tens of thousands of cars were damaged by the hail, windows were shattered, roofs were damaged, and trees were shredded of their leaves. The Lakewood area of Dallas was one of the hardest hit areas. Part of the Lakewood Theater was damaged, and thousands of divots damaged the golf course at the Lakewood Country Club. Historic homes on Swiss Avenue sustained significant roof damage with roof repairs on a few homes estimated over $100,000. A glass exhibit at the Dallas Arboretum sustained damage that was described as relatively minor. This supercell continued to track into Ellis County producing hail damage down to Midlothian. The second supercell in Dallas County tracked from Irving into Cedar Hill. Another supercell produced an EF-0 tornado, 70-95 mph downburst winds, and softball sized hail in Fannin County. The fourth supercell produced hail up to 3.25 in diameter in Collin County. Damage estimates were estimated as high as $2 billion dollars for this event, but insurance companies anticipated the final damage totals to be around $1.1 billion. One head injury was reported when the hail broke through the sunroof of a car.

A brief EF-0 tornado occurred approximately one mile north of Randolph near the intersection of CR 4145 and CR 4160. The tornado caused minor damage to at least one home, large trees, barns, and crops. The maximum winds in the tornado were estimated to be 85 mph.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 19:57 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
