Heat will be building into the weekend for southern Wisconsin, with some chances for much-needed thunderstorms, according to forecasters.
The latest drought monitor from last week reported that extreme drought continues across far southeastern Wisconsin (Kenosha, southeastern Walworth and extreme southwestern Racine counties), severe drought continues across southeastern Rock and the remaining portions of Walworth and Racine counties, and moderate drought continues for the rest of southern Wisconsin, including Dane County.
This was before storms hit last Wednesday and Thursday, but no rain has fallen since then and rain deficits are worsening again.
