Event narrative

On the afternoon of Wednesday July 17th 2013, a right-moving supercell thunderstorm produced up to one inch hail with estimated winds near 80 mph just north of the Eureka airport in Montana. According to homeowners in the area, the mostly marble-sized hail flew sideways due to the hurricane force wind damaging roof shingles, siding, windows, paint and vehicles, and shredding vegetation. Trees toppled over in a northeast direction implying that winds could have been from the southwest.

Wider weather episode

A mid-level southwest 50 knot jet maximum combined with high moisture and very warm temperatures provided the prime environment for strong supercells. These cells brought both severe wind and hail.
