The dryline served as the focus for the development of scattered thunderstorm late Wednesday afternoon (20 May). Hot temperatures, sufficient moisture, strong instability and enough wind shear allowed some of the storms to organize, become severe and generating large hail.

The initial thunderstorms formed over the southwest Texas Panhandle and northwest South Plains as well southeastern South Plains. Ping pong ball size hail fell from a storm that passed just to the west of Dimmitt, while tennis ball size hail was observed with the storm northwest of Post (see the picture at the top of this page).

One particularly intense storm formed along an outflow boundary that moved northward out of the earlier activity over the southeast South Plains. The rapidly developing storm, which was rotating anticyclonically (clockwise), raced northward over the city of Lubbock. Baseball size hail pounded parts of south-central Lubbock, while smaller hail affected much of the city, including the airport.
 
Regional radar animation valid from 5:28 pm to 6:38 pm on 20 May 2020.

Interestingly, many locations experienced only hail initially as the storm moved into the city, though the hail did gradually mix with rain too. Unfortunately, the large hail damaged and destroyed many plants, vehicles and roofs. Numerous vehicle windows were shattered, and most objects that were exposed to the giant hail incurred some kind of damage.

Aside from the hail, many locations from the central South Plains into the southern Texas Panhandle and Rolling Plains received at least a little rainfall. The rain was heaviest in a several pockets, favoring the southern Texas Panhandle as well as the southern Texas Panhandle.
