Hail — Lewis and Clark, Montana

2024-08-06 · near Marysville, Lewis and Clark, Montana

Event narrative

Trained spotter reported heavy rain and quarter sized hail.

Wider weather episode

The main day for severe weather was August 6th. A rather robust shortwave progressing across the region combined with ample surface heating to result in a round of severe thunderstorms across the region. Outflow from the previous days convection inhibited thunderstorms across most of the plains through the day, but thunderstorms forming off the high terrain of Glacier county spread southeastward with time and resulted in some damaging wind. Another rogue strong wind gust was observed on the 10th associated with a deep inverted-V sounding in Dillon.
