Millions of Americans are bracing for an extreme heat wave that will push the heat index, or feels-like temperature, into the triple digits across the Midwest and Upper Great Lakes next week.
National Weather Service (NWS) meteorologist Bryan Howell, who works at the Duluth, Minnesota, office, told Newsweek that temperatures will be as high as 93 degrees Fahrenheit in Duluth on Sunday, which is near the record high of 94 degrees, which was set in 1910. The average high for this time of year in Duluth is closer to 71 degrees.
Why It Matters
As of Wednesday afternoon, extreme heat watches were in place across states like Minnesota, Wisconsin, Iowa, South Dakota and Nebraska. Although the region can experience hot weather during the summer, NWS meteorologists warned that the incoming heat wave would bring "dangerously" hot conditions that could increase the chance of heat illness and pose serious threats should someone spend time outdoors without taking proper precautions.
The exceptionally hot weather is particularly dangerous for outdoor workers or people conducting activities outdoors during the hottest parts of the day.
What to Know
According to the NWS HeatRisk forecast tool, widespread "extreme" heat is forecast to begin moving into the region on Sunday. The heat's impact expands on Monday to include Iowa, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, New York, Missouri, and parts of Tennessee.

NWS HeatRisk
"This level of rare and/or long-duration extreme heat with little to no overnight relief affects anyone without effective cooling and/or adequate hydration," the NWS said. "Impacts likely in most health systems, heat-sensitive industries and infrastructure."
Major heat, one level below the extreme indicator, is expected to hit much of central, Midwest, and Northeast U.S.
The heat watches currently in place advise of rising temperatures on Friday that will persist through the weekend as the heat wave treks east.
In addition to the heat, AccuWeather meteorologists are warning of high humidity that can make temperatures feel even hotter.
As summer solstice approaches, the sun is at its most intense. AccuWeather meteorologists warned that exposure to heat such as this can greatly increase the risk of heat exhaustion and heat stroke, which can also affect healthy individuals.
What People Are Saying
AccuWeather Senior Meteorologist Chad Merrill said in a report: "Detroit hasn't even hit 90 degrees this year and may have a stretch of at least seven days at or above this mark coming up starting on Saturday. This would tie for the third longest streak of consecutive 90-degree days. The last time Detroit had at least seven consecutive days at or above 90 degrees was July 1-9, 2020."
An extreme heat watch issued by Hastings, Nebraska: "Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors."
What Happens Next
The heat is expected to be most widespread on Monday, with warmer-than-average temperatures persisting throughout the first half of the week for much of the region.

Rain with a high near 76 forecast Thursday for Juneteenth celebrations in Mansfield
Juneteenth will be warm and rainy in Mansfield. Showers are expected throughout the morning Thursday, according to Douglas Kahn, a meteorologist who works in the Cleveland office of the National Weather Service. "Anywhere from half an inch to an inch," Kahn said. "I can't really give you like an exact amount ... it really depends on where the strongest cells are." Thursday morning's storms are expected to follow a night of rain that was forecast to begin about 10 p.m. Wednesday. The rain showers Thursday will likely be short and will leave North Central Ohio by lunchtime. More: Prepare for a 'heat dome' to reach Ohio this weekend "Looks like they just kind of pass through," Kahn said. "Looks like the rain chances decrease later afternoon into the evening." The afternoon for Juneteenth will likely be dry, but still partly cloudy. "I have not looked at the cloud cover for tomorrow," Kahn said. A weather report from AccuWeather predicts that Thursday afternoon in Mansfield will be partly sunny with a high near 76 degrees. Scattered showers are possible throughout the afternoon Thursday. The day should be slightly breezy with wind gusts up to 30 mph. ztuggle@ 419-564-3508 This article originally appeared on Mansfield News Journal: Juneteenth will be warm and rainy in Mansfield

Heat dome will blanket much of the US, with worrisome temperatures in Midwest
Summer will make a dramatic entrance in the U.S. this week with a heat dome that will bring stifling temperatures and uncomfortable humidity to millions. The heat will be particularly worrisome this weekend across wide stretches of Nebraska, Illinois, Wisconsin and Iowa, where forecasters are warning of extreme temperature impacts. This will be the first stretch of true summertime weather for many from Midwest to the East Coast, said Tom Kines, a meteorologist at the private weather company AccuWeather. 'A lot of those folks have been saying, where's summer? Well, buckle up, because it's coming,' said Kines. The humid conditions will make places that exceed 90 degrees Fahrenheit (30 degrees Celsius) feel as much as 20 degrees hotter, said Kines. A heat dome occurs when a large area of high pressure in the upper atmosphere acts as a reservoir that traps heat and humidity, said Ricky Castro, a National Weather Service meteorologist in Illinois. According to the NWS Weather Prediction Center, daytime temperatures will be in the 90s Fahrenheit (30s Celsius) and overnight temperatures will only drop to the mid-70s Fahrenheit (mid-20s Celsius) from the Great Lakes to the East Coast during the heat wave that's expected to last into next week. Moisture blown northward from the Gulf of Mexico is fueling the muggy weather, said Jacob Asherman, a Weather Prediction Center meteorologist. This influx of Gulf moisture is fairly typical during late spring and summer, he said. The heat will be widespread into next week. On Friday, Denver could reach 100°F (38°C), according to the weather service. Chicago temperatures could reach 96 degrees (36°C) on Sunday. On Tuesday, Washington, D.C., could see a high of 99°F (37°C) and New York Central Park could reach 96°F (36°C). Several states in the Midwest could see dangerous temperature impacts over the weekend, according to a weather service measure. Parts of Nebraska and Kansas will be in the highest of four categories on the scale on Saturday, meaning that anyone without effective cooling or sufficient hydration could face health risks. On Sunday, Iowa, Wisconsin, Missouri and Illinois also see a category 4 rating. Humidity is the amount of water vapor in the air, and the heat index is what the temperature feels like when the humidity outside is factored in, according to the weather service. When humans sweat, it cools the body down because it absorbs and removes heat as it evaporates off the skin. The air is saturated with water on humid days, which makes it harder for sweat to evaporate. Hot and humid days can be dangerous when the body is unable to cool itself off and can exacerbate pre-existing health conditions and even lead to heat stroke. Minimizing direct sun exposure, wearing loose and light-colored clothing, staying hydrated and spending time in air-conditioned spaces are ways to cool down during extreme heat, according to the NWS. Some parts of the U.S., such as Phoenix, Arizona, are famously hot without the mugginess. Phoenix and nearby desert regions experience this so-called 'dry heat' due to being located far away from large water bodies, mountains that block moist air masses and weather patterns that bring scarce precipitation. Sweat evaporates faster in dry climates compared to humid ones. This can be dangerous because it is easy to underestimate how dehydrated you are, according to Johns Hopkins University and Johns Hopkins Health System. In places such as Iowa, crops can affect the humidity in summer months. Plants feel the effects of hot weather and some people in the Midwest are familiar with ' corn sweat,' which is when crops move water to their leaves and other surfaces so it can evaporate, according to the Ohio State University. Madison County, Iowa, farmer Ryan Marquardt said corn sweat is 'not as bad as a sauna, but it definitely would have a sauna effect. It's humid in there (the cornfield), so you're gonna sweat.' Cornfield contributions to the overall humidity are much lower compared to the humidity winds carry from the Gulf of Mexico, according to OSU. ___
