Event Summary: April 20, 2025

Overview

A strong low pressure moved northeast over Iowa during the afternoon and evening April 20th, 2025. This storm system brought a cool widespread rain through the morning, but by afternoon, warm moist air began moving into southeast Iowa, creating a slow moving line of thunderstorms with very heavy rain. Rainfall of 1 to 3 inches was reported over portions of eastern Iowa, especially near Cedar Rapids metro areas, where there were reports of urban flash flooding during the evening hours. Severe storms developed along the line as it moved from northeast Missouri, across southeast Iowa, into Illinois. From 730 PM to 10 PM numerous tornado warnings were issued along the line, especially from the Burlington Iowa area northeast through Geneseo Illinois. Several reports of tornadoes were seen by spotters, and scattered reports of damage to outbuildings and trees were reported as of late evening April 20.
