Heat will be building into the weekend for southern Wisconsin, with some chances for much-needed thunderstorms, according to forecasters.

Wisconsin drought monitor as of 7-15-21

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.

Madison’s July total of 1.04 inches is 1.98 inches below normal, the meteorological summer (June through August) total of 5.64 inches is 2.66 inches below normal, and the 2021 total of 12.82 inches is 8.61 inches below normal.

The Climate Prediction Center outlook for August and into early fall indicates somewhat enhanced probabilities for above normal temperature and little signal one way or the other for precipitation.

The chance for showers and storms is 20% Thursday night and Friday, with a low around 69 and a high near 89 under sunny skies, cooled slightly by southwest winds at 5 to 10 mph.

The Weather Service said chances for showers and storms continue at 30% Friday night, 40% Saturday, 20% Saturday night, and 20% Monday through Tuesday.

Skies over Madison should be partly sunny Saturday, sunny Sunday, mostly sunny Monday, and sunny Tuesday, with highs near 89, 90, 89 and 91, and lows Friday night through Monday night around 74, 70, 67 and 68.
