Dangerous heat returns to Southeast Michigan this week
The late part of this week is at the center of a fiery bullseye as temperatures and dewpoints spike.
Highs on Thursday will top out in the low 90s, but the biggest issue is the heat index, which will reach the 100 to 105 degree range.
When the heat index reaches these temperatures, the heat stress on your body overcomes its ability to cool itself on its own.
With the criteria we expect to be at, a heat advisory will likely be issued by the end of the day on Wednesday. A warning requires three hours or more of 105-plus degrees heat indices.
Take breaks in air conditioning, stay hydrated, and we'll have a chance to cool a bit on Friday.

Maps show U.S. heat advisories, high temperatures as heat dome moves east
The extreme heat that has baked much of the central United States this week is slowly shifting east ahead of the weekend, forecasters said. More than 130 million Americans across at least 20 states are under heat alerts on Thursday. Parts of the Midwest, including the Corn Belt, have felt the high temperatures for multiple days. Temperatures on Thursday are forecast to be 10 to 15 degrees above average for this time of year with feels-like temperatures over 100 degrees expected in multiple areas. Some parts of the Mississippi Valley will continue to see high temperatures over 90 degrees for a few more days, even as the heat dome moves over parts of the Northeast. A heat dome happens when hot air is trapped over an area due to a persistent high pressure system, William Gallus, a professor of atmospheric science at Iowa State University, said. Heat domes can last for days to weeks and can stretch over multiple states. With extreme heat in the Corn Belt, a region including parts of the Plains and Central Mississippi Valley, a phenomenon known as corn sweat has made the humidity worse, experts said. "There are pores on the bottom side of the leaves," Iowa state climatologist Justin Glisan told CBS News national correspondent Lana Zak. "And that's where oxygen is released, but also water vapor." The process can add up to 10 degrees to the feels-like temperature, Glisan said, because just 1 acre of corn can release as much as 4,000 gallons of water into the air per day. Iowa has around 13 million acres of corn.

130 million people on alert as hot, sticky weather expected from Texas to Maine
At least 130 million people from Texas to Maine are under alert for dangerous heat and humidity over the next few days. Hot and sticky temperatures will make it feel as high as 115 degrees in parts of the Mississippi River Valley. Even Niagara Falls will get no relief from the sweltering conditions; the tourist destination will feel like the mid-to-upper 90s on Thursday. The heat index in Chicago, which factors in humidity, will make it feel in the triple digits and nighttime and early-morning temperatures will provide little comfort. As of 4 a.m. Thursday, the actual temperature was 80 degrees, or 85 with the heat index. Texas will be just as hot on Thursday, as the heat index is expected to make it feel 107. Up north in Detroit, it's forecast to feel 102. Dangerous heat will spread to the Mid-Atlantic and Northeast as temperatures in the I-95 corridor from Washington, D.C., to Portland, Maine, will make it feel like it's in the mid-90s on Thursday. Maine is under a heat advisory mainly for Friday as the heat index will make Portland, Maine, feel like it's 100 degrees. New York City, Boston and Philadelphia are also bracing for extreme temperatures. On Friday, the feels-like temperature is expected to be reach 104 in New York City, 103 in Boston, 106 in Philadelphia and 109 in Washington, D.C., and Baltimore. Meanwhile, the Midwest and the Southeast is expected to see hot and humid weather stretch into the weekend and into early next, as the heat indices are expected to make it feel 110 degrees in some parts.

Besides the heat, the Midwest, specifically Kansas and Missouri, is expected to see a summer flash flooding continue. Strong thunderstorms on Thursday could cause flooding across the region, which is still recovering from flash floods earlier this week.

The Kansas City region may see the brunt of storms with multiple rounds of heavy rain possible.

Tracking heat: Here's where it will feel like 110 degrees
Dangerous heat is peaking today for millions in the central United States as a heat dome in summer's hottest month lives up to its reputation — but sauna-like conditions are only just beginning for areas farther east. The heat index — how hot it actually feels given the temperature and humidity — will top out in the 100s from the Gulf Coast to the Midwest Thursday afternoon while it soars above 110 degrees in some parts of the Mississippi Valley. Memphis, Tennessee, had its hottest day of the year so far on Wednesday with a high of 97 degrees and a heat index of at least 106 degrees. The city could match that intense heat Thursday while just south in Greenville, Mississippi, the heat index could hit 110 degrees. Farther north, Chicago's high temperature of 94 degrees could come within a degree of its hottest day so far this year. That same roasting summer heat started creeping into the Mid-Atlantic and Northeast Thursday. High temperatures in the 90s are likely Thursday afternoon as far north as Burlington, Vermont – located about 30 miles from the Canadian border. The worst heat for the East arrives Friday with high temperatures in the middle to upper 90s expected from Washington, DC, to Boston. These temperatures are up to 10 degrees higher than the typical hottest conditions for this time of year and could challenge the high temperature record for the day in Baltimore, Philadelphia and New York City. The heat index will reach or surpass 100 degrees for many major metros: Washington, DC, and Philadelphia will feel more like 105 degrees Friday afternoon and Baltimore will feel nearly 110 degrees at times. Heat remains the deadliest form of extreme weather in the US. Globally, heat waves are becoming more frequent, more severe and lasting longer as the world warms due to fossil fuel-driven climate change. More than 60 million people in the eastern half of the US are under at least a Level 3 of 4 'major' heat risk on Thursday, with that total jumping to more than 90 million on Friday, according to the National Weather Service. Heat this severe impacts anyone without access to effective cooling or proper hydration, not just vulnerable populations, according to the National Oceanic and Atmospheric Administration. And for those without air conditioning, staying indoors can become deadly during the hottest parts of the day, the agency warns. Humid conditions will also prevent temperatures from cooling significantly overnight. It could still be close to 80 degrees in Washington, DC, by sunrise Saturday — nearly 10 degrees higher than a typical low for late July. When overnight temperatures don't cool down enough to offer relief for overheated bodies, people are at greater risk for heat-related illnesses. Nighttime temperatures are taking the hardest hit from climate change, warming faster than daytime highs. Climate change is making this week's heat wave at least three times more likely for nearly 160 million people, almost half the US population, when compared with a world without fossil fuel emissions, according to an analysis from the climate research nonprofit Climate Central. The heat dome will shrink Saturday, replaced by more typical, though still very toasty, late July conditions parts of the Northeast and Midwest. Sweltering heat will persist through the weekend, mainly in southern parts of the Ohio Valley and Mid-Atlantic on Saturday and in portions of the Southeast Sunday. That general trend of a hotter-than-normal South is expected to continue through next week, according to the latest Climate Prediction Center forecasts. CNN Meteorologist Briana Waxman and CNN's Luke Snyder contributed to this report.
