2025-09-14 · near Sioux City, Woodbury, Iowa

Event narrative

Thunderstorm wind gusts for about 1 or 2 minutes broke several 3 to 4 inch diameter tree limbs.

Wider weather episode

A weak impulse lifted northward through the Central Plains within a high amplitude upper air pattern and around 30 knots of mainly deep-layer speed shear. Afternoon surface heating resulted in 1000-1500 J/kg MLCAPE and almost an equal amount of DCAPE given broad mid-level dry air. The thunderstorms that developed were relatively brief, but produced sporadic damaging wind gusts.
