MINNEAPOLIS, MN — Dangerous heat settles over Minnesota on Monday, with temperatures climbing into the upper 90s and heat index values pushing close to 110 degrees in some spots. The National Weather Service has issued an extreme heat warning for parts of central and southern Minnesota, while a heat advisory is in effect farther west and north.
Most of the day should stay dry under mostly sunny skies, but conditions remain muggy and unstable. A few thunderstorms may develop after sunset and linger overnight.
Heat Warning In Effect
The extreme heat warning runs from 9 a.m. Monday through midnight Tuesday for parts of central and southern Minnesota, and it also reaches into northwest and west-central Wisconsin. In those areas, the heat index could climb between 100 and 110 degrees.
Other parts of western and north-central Minnesota are under a heat advisory, where the heat index may top 100 degrees. Monday night will stay warm, with lows only dropping into the 70s.
Storm Risk Monday Night
A cold front moving into western Minnesota could help trigger storms Monday evening, although a strong cap in the atmosphere may slow development. If storms do form, forecasters say they could become severe.
The main threats are damaging wind gusts of 60 to 75 mph or higher and hail up to 1 to 1.5 inches or larger. An isolated quick tornado spin-up and locally heavy rain are also possible.
Hot Pattern Stays
Storms are expected to reach the Twin Cities metro between 9 p.m. and midnight, with the strongest threat across the FOX 9 viewing area from 7 p.m. to 1 a.m. Much of the activity should move east of Minnesota shortly after midnight.
Tuesday looks hot and humid again, with highs in the low 90s and another chance for thunderstorms late in the day. The stretch of 90-degree heat and periodic storm chances is expected to continue through much of the week before temperatures ease into the 80s by the end of the holiday weekend.
