What the reports say
Written by National Weather Service staff at the time of the event · public domain
A supercell thunderstorm moved rapidly northeast across far northwestern Treasure County. This storm then put out an outflow boundary that raced eastward across central Treasure County into the Yellowstone River Valley. An area of enhanced wind, estimated at 80 mph, developed in an area just north of Hysham northward to the Yellowstone River. It���s estimated that upwards of 50 trees were either uprooted or snapped off. In addition, a mobile home was pushed off its blocks and a small garage (poorly constructed) was destroyed but contents left in place. Another home had numerous evergreens uprooted with damage to a garage and shed.
