According to Fox31:
A monsoon surge has moved into Colorado and is expected to last through Friday.
Heavy rain and thunderstorms pushed into Estes Park on Wednesday evening, bringing heavy rain. The storm system also delivered around one foot of hail, according to resident Kirby Hazelton.
Some residents said the hail was so deep that it caused traffic problems in downtown Estes Park.
Snowplows and front loaders were used to clean the hail up.
