A few breaks in the clouds possible during today's solar eclipse

Forecast for August 21, 2017

An Alert Day is in the forecast for tonight for the potential for severe thunderstorms Monday night into early Tuesday morning.

Skies will be variably cloudy today, and it will be warm and humid with a chance of showers and thunderstorms. High temperatures will reach the lower 80s. The solar eclipse will begin in Madison at 11:50 a.m. and will reach its maximum at 1:15 p.m. The eclipse will end at 2:38 p.m. At the eclipse maximum, 85% of the sun will be covered. Cloud cover will be widespread on Monday, but there is a chance we could see some breaks in the clouds during the duration of the eclipse. 

A cold front will move through southern Wisconsin later tonight with showers and thunderstorms. There is the potential for isolated severe thunderstorms to develop along the cold front, with an outside chance of a squall line of severe thunderstorms developing.

Behind the cold front, Tuesday will be mostly cloudy, breezy and cooler with showers and thunderstorms ending early and skies becoming partly sunny in the afternoon. High temperatures will be in the middle 70s.

Pleasant late August weather will settle over Wisconsin from Wednesday through Friday with mostly sunny skies and pleasant temperatures. High temperatures will reach the middle 70s each day.

Saturday will be partly sunny and mild with high temperatures in the middle 70s. Sunday will be variably cloudy with a chance of showers and thunderstorms developing. High temperatures will reach the upper 70s.

Near-normal temperatures are expected for the start of the following week. Next Monday will be variably cloudy with a chance of showers and thunderstorms and highs in the middle 70s. Next Tuesday and Wednesday will be partly sunny and pleasant with highs in the middle 70s.
