A cold front tracked west to east across western and central Wisconsin during the  afternoon and evening hours of July 14th. Severe thunderstorms developed along the cold front and produced severe wind gusts, funnel clouds, large hail and one tornado. The severe winds knocked trees down onto power lines and caused power outages across portions of central and western Wisconsin. Trained spotters estimated hail up to two inches in diameter near Osseo in Trempealeau County. The severe thunderstorms also produced an EF1 tornado in northern Jackson and southern Clark Counties. These storms also produce very heavy rain which caused flash flooding across southern Jackson, northern Monroe and Richland Counties. Law enforcement reported several roads closed due to water over roads and washouts. Cooperative observers and amateur radio operators reported rainfall amounts ranging from three to seven inches across southern Jackson and northern Monroe Counties.
