Heavy Rain and Flooding Threat in the Ohio Valley

Gulf moisture will combine with a cold front and will bring heavy rain and scattered flash flooding over parts of the Mid-South into the Ohio Valley through the morning and the Ohio Valley and Central Appalachians on Tuesday. Showers and thunderstorms, some severe, are expected over the Southern Rockies/Southern High Plains on Tuesday. Read More >

Overview

Two main rounds of storms moved through the region over the weekend of July 13-14. The first developed Saturday afternoon with storms quickly organizing and intensifying as they moved into southeast Minnesota and west-central Wisconsin. These storms quickly morphed into a bow echo that produced substantial tree damage as it raced eastward across Trempealeau and Jackson counties into central Wisconsin. A few other trailing storms produced large hail up to 2" in diameter (mainly within the Mississippi River Valley) and scattered wind damage across southeast Minnesota. 

A second round of storms developed Saturday night in the very humid airmass overhead. Heavy rain with these storms, falling over areas that had already received substantial rainfall from the first round of storms, led to localized flash flooding and rapidly rising rivers Sunday morning across western Wisconsin.
