The heatwave engulfing much of the US this weekend is reaching temperatures hot enough to bake cookies in a car.
One Wisconsin newscaster put the heat to the test, placing raw cookie dough on a baking sheet in his car with a thermometer.
The car reached 170 degrees - hot enough to begin baking the cookies - serving as a warning to parents and pet owners.
Forecasters are calling this a 'heat dome' with 18 states having already issued heat advisories through the weekend and into the week as afternoon highs are expected to be 10 to 20 degrees above normal.
