Midwest, Northeast to experience extreme heat wave

Americans from Kansas to Maine are bracing for a grilling heat wave this week that could see the mercury hit triple digits with high humidity.

Dangerously hot temperatures have sparked warnings from weather and health officials across the country, as concerns rise for heat exhaustion and dehydration.

An “extreme” heat risk, defined as long-term heat with “little-to-no overnight relief,” will start in Iowa and Missouri on Monday and move east over the course of the week, the National Weather Service (NWS) forecast.
