DALLAS (AP) - Sweltering summer temperatures in Dallas are expected to top 100 degrees for the 10th consecutive day as excessive heat warnings grip many central and southern states.

The National Weather Service reported Monday that heat advisories are in place from Georgia to Illinois and back down to Oklahoma. Temperatures in those places may not reach 100 degrees, but the heat index could make it feel like triple digits.

Texas has seen these summers before. Dallas hit the 100-degree mark for nearly three straight weeks as recently as 2006, and meteorologist Jesse Moore says the city isn't even technically under a heat advisory because the area is used to these temperatures.

That's not the case in Cincinnati, where an excessive heat warning accompanies a possible heat index of 104 degrees.
