It's going to be hot. Very hot.

WCCO's Paul Douglas says, "It’s been a swampy week with dew points in the 70s, meaning a tremendous amount of moisture in the air. Light steering winds aloft have caused thunderstorms to stall and regenerate in the same spot, pouring out a month’s worth of rain in an hour or two. Typical for Orlando and Manila, but unusual at this northerly latitude!  These are two of the hottest days of the year."

Brutal heat is expected to hit parts of Minnesota starting Thursday afternoon and last into Friday. The National Weather Service says heat indices will reach 100 to 105 degrees. The highest indices will hit between 2 p.m. and 8 p.m. both days.

A Heat Advisory goes into effect Thursday at noon and will last until 7 p.m. Friday for south central and east central Minnesota into west central Wisconsin. Severe weather is also a possibility.

Minnesota isn't alone of course, as the heat is searing most of the country, especially through the Midwest and East Coast, with heat index values climbing to near 110F in some locations. Locations under an Excessive Heat Warning include Oklahoma City, Wichita, Kansas City, St. Louis, Omaha, Des Moines and Philadelphia.

This heat isn't to be taken lightly, especially since we will not cool down much at night due to the humidity.  The National Weather Service has some tips for staying safe in the heat.  Those include staying hydrated, take breaks in the shade if working outside, and never leave kids or pets unattended in a vehicle, where high temps can become deadly in only a couple of minutes.  Already in 2019, there have been 9 toddlers that died in hot cars.

Here's the good news as the humidity drops by the weekend.  Paul Douglas tells us, "We get some relief.  A passing shower or thundershow Saturday as cooler air moves in.  Sunday, the nicer, sunnier, drier day.  Comfortable dew points with a high near 81."
