Hail — Woodbury, Iowa

2025-06-28 · near Leeds, Woodbury, Iowa

Event narrative

Observed hail was pea to nickel size, although most hailstones were the size of dimes.

Wider weather episode

Thunderstorms developed along a nearly stationary pre-frontal boundary during the early evening across south central South Dakota. As cold pool development forced storms eastward off the initiating boundary into an environment with appreciable DCAPE and deep-layer shear of 40 to 50 knots, thunderstorms organized into a small bowing segment which plowed east and southeast with up to nearly 90 mph winds. After several hours, storms moved into a less favorable environment with both lesser shear and instability toward the James River Valley and weakened.
