On May 8, Colorado experienced its first widespread severe convective event of the 2017 season. Storms developed across the eastern half of the state by early afternoon in response to a closed upper low slowly shifting east toward the region. Given the setup, storms moved from south to north across the state, producing widespread large hail and heavy rainfall. Below is a GOES-16 0.64 um visible imagery animation of storm development and evolution across the state from 1802 UTC – 2357 UTC. Strong updraft signatures are obvious with many of the storms in the 0.5 km imagery, including overshooting tops and above anvil cirrus plumes.
