More thunderstorms and heavy rain are possible late Monday afternoon into the evening across southern Wisconsin as a cold front moves through, according to forecasters.

But beautiful weather is expected after the front passes, with sunny skies and highs in the 70s on tap for several days.

Officially, 1.8 inches of rain was recorded at the Dane County Regional Airport on Sunday, when the county was under an urban and small stream flood advisory from 4:30 p.m. to 10:30 p.m.

After some patchy fog burns off — low-lying rural locations and river valleys may see isolated dense fog — Monday should be mostly sunny with a high near 85 in Madison and winds developing out of the southwest at 5 to 10 miles per hour.

There’s a 10 percent chances of showers and thunderstorms after 5 p.m. growing to 50 percent overnight, mainly before 4 a.m., as the low eases to around 66 and winds turn out of the northwest.

The National Weather Service said there is the potential for more heavy rain from any thunderstorms that develop, and a slight risk for severe thunderstorms northwest of a Ripon to Portage to Lone Rock line. The main threats are large hail and damaging winds.

Tuesday through Thursday should be sunny to mostly sunny with highs in Madison near 76, 76 and 78, and lows around 56, 59 and 62.

Chances for storms return Thursday night and Friday and will linger through the weekend as low pressure approaches the area from the northwest, the Weather Service said.

Officially, the chances for showers and storms are 20 percent Thursday night, 30 percent Friday and Friday night, 40 percent Saturday, 30 percent Saturday night, and 20 percent Sunday.

Highs Friday through Sunday should be near 79, 75 and 74, and lows Thursday night through Saturday night are expected around 62, 60 and 56.

27 Storm Track meteorologist Brian Olson also expects a muggy Monday with a few storms late in the day, followed by a beautiful stretch of weather with just chances for isolated showers and storms Friday and Saturday.

Olson expects highs in Madison Monday through next Monday near 86, 75, 75, 79, 80, 76, 78 and 77, and overnight lows around 63, 50, 57, 62, 61, 57, 55 and 60.
