A cold front, with a low pressure system moving along it, crossed the middle Ohio River Valley on the 28th. A mid level disturbance also crossed during the afternoon. In abnormally high atmospheric moisture showers and thunderstorms were very efficient rainfall producers with 1 to 2 inches falling in under 30 minutes in the strongest storms. The heaviest rain fell along and north of the US 50 corridor where 2 to 4 inches were measured from late on the 28th into early on the 29th. This resulted in serious flash flooding, leading to an emergency declaration by West Virginia Governor Jim Justice for multiple counties in northern West Virginia. The area also received a major disaster declaration by the federal government. See FEMA DR-4331 for additional information.
