Heavy thunderstorms might lead to flooding Saturday night

After a nice weather day Saturday with sunshine and high temperatures in the middle 70s, showers and thunderstorms are likely for Saturday night. After the recent heavy rainfall, any additional rainfall may lead to flooding. As a result, the National Weather Service has issued a Flash Flood Watch for areas west of Dane County from Saturday evening through 7 a.m. Sunday. The watch begins at 7 p.m. for areas west of a Platteville to Lone Rock line, and at 10 p.m. for the counties immediately to the west of Dane County.

A few thunderstorms overnight are capable of producing heavy amounts of rainfall. General rainfall amounts of around three-quarters of an inch are expected southwest of Madison tapering to less than a quarter inch well northeast of Madison. However, an inch or two of rain is possible in isolated thunderstorms, especially to the west of Madison. This could lead to localized flooding in areas that receive heavy rain. Much of southern Wisconsin to the west and south of Madison has picked up from three to six inches of rain over the last few days. Additional rainfall may lead to flooding in these areas.

After the thunderstorms end Sunday morning, partly sunny, warm and humid weather is expected from Sunday afternoon through Wednesday of next week. Rain chances will be low until a cold front approaches Wisconsin from Wednesday night through Thursday, resulting in the next chance of showers and thunderstorms.
