Hammond Shelf Cloud
Even though 2019 was a very active storm season overall, it started quite late. It was well into June before there were any thunderstorms worth chasing locally. I caught up with this long shelf cloud on the plains outside of Broadus, Montana. When air cooled by rain hits the ground, it spreads out ahead of the storm. This lifts the warmer, moist air ahead of it, which condenses into a shelf cloud. They are usually associated with strong winds and heavy rain, but rarely tornadoes because they do not have the right shape.
