I live in the mountains just west and not too far from Denver. From Spring through summer, it is possible to get hail everyday. Granted, it is mostly non-damaging size hail but the potential for damaging sized hail is always a possibility.
I believe the Denver metro area does not see as much hail but again, the potential is always there. You would be surprised how many cars you will come across in Denver that look like golf ball skin. When I am doing work in Denver or parked at the airport, I park in a parking structure versus parking outside when during that time frame mentioned above.
Yes, I realize what I am saying may seem like an exaggeration but hail does happen here a lot. A majority of the time it is not damaging... but I like to go by the "better safe than sorry" approach to not have to give it a second thought. To each their own. :)
