A triple-digit heatwave is causing serious concerns in North Texas.

The official high temperature at Dallas/Fort Worth International Airport peaked at 105 degrees Sunday, and there's no relief in sight.

The National Weather Service has extended its heat advisory for Dallas, Tarrant and counties to the north and east through 8 p.m. Tuesday.

Firefighters in Hunt County had to battle the heat as they worked to control a grass fire north of State Highway 276 in Union Valley.

The Texas Forest Service was called in to help Union Valley volunteers. No structures were reported damaged or destroyed.

"We are definitely in the dog days of summer," said WFAA meteorologist Steve McCauley, who forecast high temperatures ranging from 103 to 109 in North Texas on Monday.

The extreme heat is also having an effect on the water levels of area lakes, all of which are less than full.

"We're losing about an inch or two every day," McCauley said, noting that Possum Kingdom Lake is 7 feet below normal level and Lake Bridgeport is 8 feet low.

The forecast indicates it will remain dry in the region, and drought conditions are likely to become more severe.

"When you do the math, right to the middle of August, less than one-tenth of an inch of rain falls here in North Texas," McCauley said.

Monday's forecast high is 106 degrees, with temperatures in the same range through Thursday.

"Maybe cooling down to about 100 degrees with increasing humidity next weekend," McCauley said.
