Updated at 10 a.m. Saturday with the latest forecast.
An excessive heat warning was extended from the west into the Dallas-Fort Worth area through Saturday evening.
Now multiple counties are under the warning as high temperatures are expected to reach between 105 to 110 degrees.
Sunday is forecast to reach 100 but will cool down later in the day ahead of a cool front, bringing temperatures to the 90s for next week.
Friday was the hottest day of the year so far, reaching 103. The record high was 106 in 2012.
This weekend is forecasted to be hot enough to be dangerous because of the temperature and the dew point.
Even a small amount of moisture in the air makes it feel even warmer.
Prior to this week, DFW Airport had only reached 100 degrees twice this summer.
Stay safe by avoiding the outdoors for extended periods of time, wear light-colored clothing and stay hydrated.
Remember cars can heat up in temperatures like these within minutes, so check the backseat for pets and children before getting out.
The heat won't stick around.
Monday will be almost 10 degrees cooler thanks to a summertime "cold" front which brings cooler temps and the chance for some scattered showers and storms starting Sunday late afternoon into evening lasting through Monday morning.
