A bulge in the jet stream across American skies is set to trigger an extreme heat dome this week - bringing triple-figure temperatures to large swathes of the country.
Nearly 85 million Americans, from South Dakota to Texas and North Carolina to Florida, are already experiencing the extreme heat warnings.
But the sweltering conditions are expected to intensify this week - causing temperatures to swell into the high 90s and surpass 100s in some areas.
Dallas and Kansas City are among the densely-populated urban areas where the heat index is expected to go above 100F, triggering a drought due to the lack of rainfall.
AccuWeather Senior Meteorologist Chad Merrill said: 'This has the look of a long-lasting heat wave with limited rainfall.
'Drought will expand through the central Plains by mid-August and worsen in Kansas and Nebraska, where there are already pockets of moderate to extreme drought.'
The heat wave could continue until the last weekend of July in the Plains and South, before the rising temperatures move westward towards the Rockies.
A heat dome is a high-pressure atmospheric system that causes warm air to be pushed to the Earth's surface - often becoming trapped for longer periods of time.

Years ago we learned that when the Jet stream makes any form of Omega over you and you are in the eye of it, sell your cows forget about a garden and prepare for months of hot day weather.
It’s been endless days of 90+ here in Raleigh. I’ll take the heat over the cold anyday though!-)
Oh I know I just have to say that because I know what is coming.
I’m staying inside till the sun goes down and it’s cooled off for the next week.
I’m in AZ and it’s barely hit 100° twice this summer. 80° now at almost noon...
Yes, it is crazy... Last week I woke up sorry I left the swamp cooler on all night. I was frozen when I got up.
I have never seen anything like this almost my whole life in the very same location.
Got some work done though with this great weather...
OH MY GOD. Jet stream BULGE and HEAT DOMEs. We’re doomed. We must give all our power to the government to save us from global weather. We never had hot summers before.
Oh yes, SUMMER!!
Also, must only happen during Republican presidents...🤔
