UPDATED (See bottom)
While on vacation, I noticed that up in my home town (Butte, MT), quite the hail storm was going on. It wasn't until after getting back home (to Denver) that I was able to piece things together.

Also, below I included to radar images (one base reflectivity and one storm relative velocity) of the storm as it passed over Butte (in the lower right). Click the image for a larger view.
This storm was something that I had not witnessed while living there (for 23 years of my life), so it kind of stings that I missed it ...
My parents' neighbor shared with me some pictures of the event.
Anyway, yeah ... 2.5" hail in the mountains of Western Montana ... that would have been a HELL of a storm.
UPDATE: The NWS in Missoula has posted a page with a couple pics and a radar loop. Click HERE
