One of the hottest weekends of the summer triggers heat advisory for the Twin Cities through Monday

Muggy, tropical-like heat has engulfed the Twin Cities, making this weekend one of the hottest so far.

With the heat index hovering in the upper 90s throughout the day, the National Weather Service issued a heat advisory for the metro through 10 p.m. Monday — only the second heat advisory for the area so far this summer. A heat advisory is triggered in the metro when the heat index, or what it feels like to be outside, reaches 90.
