Hail — Monroe, Illinois

2024-04-02 · near Columbia Gebhardt Ar, Monroe, Illinois

Wider weather episode

Through the day of April 1, a warm front lifted north and left much of the area in a warm, moist, and increasingly unstable airmass. This instability combined with strong vertical wind shear to support multiple waves of severe thunderstorms that tracked along and south of I-70 from the evening of April 1 through the early morning of April 2. Into the evening and overnight, a transition to clusters and lines of thunderstorms occurred accompanied by hail up to quarter size (1 diameter), damaging winds, and flash flooding in southwest Illinois.
