The Midland/Odessa radar (KMAF), 54 km away, was scanning. The volume nearest the first event began at 22:42 UTC.
2 hail, 2 flash flood, 1 thunderstorm wind. Local standard time, as filed.
The first of several rounds of severe storms impacted the northwest Permian Basin during the late afternoon as convective development continued to increase towards the northwest. A severe thunderstorm rapidly developed over Andrews and produced hailstones ranging in size from nickels to golfballs. No damage was reported.
The initial severe storm that developed over Andrews evolved into a cluster of strong to severe thunderstorms. A second cell produced large hail in Andrews west of U.S. Highway 385. As the complex propagated southeast, it produced a six miles long swath of penny size hail southeast of the city. The hail was described as "mushy" and disintegrated upon impacting the ground.
Storm spotters and local officials reported flash flooding in Andrews. Several city streets were inundated by flowing water. High water entered houses in parts of the city and caused structural damage. In addition, fire department officials conducted several high water rescues when motorists were stranded by flood waters.
The complex of severe storms propagated southeast from Andrews County and struck the city of Midland. Severe winds broke several large tree branches measuring six inches in diameter in a residential area near downtown.
Urban flash flooding resulted in high water flowing through city streets near the intersection of Garfield and Loop 250.
