America roasts under brutal heatwave: 100million under heat warnings as temps soar and at least two kids left in hot cars die – so how hot will it get in your state?

America is experiencing a brutal heat wave, with more than 100 million people under heat warnings as temperatures soar into triple digits across the country.

Tragically, at least two children left in hot cars have died as sweltering conditions continue in multiple states in June.

Millions of people in the US were under heat warnings on Monday, while East Coast cities braced for more record temperatures as the heat dome causing the dangerous conditions spreads to the West Coast.

Baltimore and Philadelphia are forecast to reach records of around 90 degrees Fahrenheit, while temperatures in states like Idaho, Montana and Wyoming will climb into the 90s and reach as much as 15 degrees above normal for this time of year.

The extreme heat is expected to shift toward Nebraska and Kansas on Monday, the National Weather Service (NWS) said.

Cities across the South and Midwest are expected to swelter Monday, including Kansas City, Dallas, Little Rock, Oklahoma City, Omaha and Houston, where heat indexes will reach as high as 110F.

Officials warned of dangerous conditions in the Philadelphia region, where high humidity could cause heat indexes above 105F, making it feel even warmer than the actual temperature.

Meanwhile, parts of the country from the Gulf Coast across the Plains and the Midwest will experience heat and humidity above 105F Monday afternoon.

South Dakota and Minnesota are also expected to experience triple-digit heat indexes.

From Monday afternoon through Tuesday, the epicenter of the intense summer heat will move to the central and southern parts of the province, hitting Oklahoma and Texas on Wednesday.

“It probably means we’ll see intermittent periods of excessive heat across a fair portion of the country through July,” NWS meteorologist Marc Chenard said. “Not continuously in one place, but the overall pattern will continue to favor these above-normal temperatures.”

Temperatures have cooled in the Ohio Valley, Great Lakes and New England regions, but extreme heat in the 90s continues to extend Virginia to New York.
