Dense Fog Leads to Weather Advisory

Rainy conditions in Southeastern Wisconsin is causing the entire area to be under a dense fog advisory, according to the National Weather Service.

Visibility in Waukesha, Milwaukee and other southeastern counties was reduced to about a quarter-mile or less, and will last much of Tuesday morning. The National Weather Service also reports a hazardous weather outlook for the rest of the week because of the front.

"There is a slight risk of severe thunderstorms as a strong low pressure and a warm front approaches the region, especially this afternoon and evening," the weather outlook says.

That warning holds true Wednesday through Monday, and the moist conditions will likely continue to produce heavy fogs all week.
