A heat advisory is back for the Metroplex, as well as counties to the North and East. The alert, issued by the National Weather Service’s Fort Worth office, will start at noon Monday and continue through 7 p.m. Tuesday. It warns of heat index values up to 107 degrees, which increases the risk of heat-related illnesses.

A heat advisory is in effect until 10 p.m. for Metro Detroit as temperatures are expected to feel above 100 degrees, according to the National Weather Service. Monday's temperature, humidity and light wind are contributing to the conditions, according to Andrew Arnold, a meteorologist at the NWS Detroit office.

Extreme heat and humidity return to NYC to start the week, and we could see our second heat wave of the season.
