A second squall line moved through during the early morning hours of the 21st, and a third one moved through shortly after dawn. The series of hailstorms caused nine million dollars damage. Hailstones as large as grapefruit caused heavy damage to trees, utility lines, crops and buildings. The thunderstorms also produced as much as five inches of rain in an eight hour period.

2001: Large hail driven by strong thunderstorm winds raked Denver International and front-range airports. Wind gusting to 54 mph along with hail as large as 2 inches in diameter punched at least 14 thousand holes and cracks in the flat roofs of several buildings at Denver International Airport. Also, 93 planes and hundreds of cars were damaged. About 100 flights had to be canceled stranding 1500 travelers. The Airport was completely shut down for about 20 minutes. The storm also damaged ground avoidance radar used to track planes on the ground to prevent collisions. Damage was estimated at 10 million dollars not counting the cost to the 93 airliners. The storm moved south and struck Watkins Colorado with hail as large as 2 1/2 inches in diameter and winds gusting to 60 mph.
