North Texans will be feeling the heat this week as maximum heat-index values are expected to register between 102 and 106 degrees and atmospheric conditions heighten the chances of ozone air pollution, according to the National Weather Service.
The seven-day forecast has temperatures sitting in the high 90s in DFW until later in the week, when temperatures are expected to rise to 100 degrees on Friday and Saturday.
On Monday, the weather service issued an ozone action alert, urging people to minimize the chance of increased pollution by doing such things as sharing a ride, walking, riding a bicycle and keeping vehicles tuned up.
"The ozone action alert gets updated day by day, but it will be in place for Tuesday as well," said Bianca Villanueva, a weather service meteorologist.

The rise in temperatures coupled with more people spending time outside during the long Memorial Day weekend has led to a few heat-related incidents.
On Monday, six people were treated for heat-related illnesses, with three being transported to area hospitals, according to MedStar spokesman Matt Zavadsky. On Sunday, at least 11 people were transported to area hospitals due to the hot weather, including one adult male with critical and potentially life-threatening injuries.
"He was transported to John Peter Smith hospital at 4:30 p.m.," Zavadsky said in an email Sunday.
Over the entire holiday weekend, Medstar handled 34 heat-related responses, with 20 of the victims being transported to area hospitals, Zavadsky said.
Roadways also gave way to the heat on Sunday. Grapevine police released video of several cars going slightly airborne on Sunday afternoon in the eastbound direction along the Bass Pro bridge over SH-121. Police said some of the concrete on the bridge buckled up about a foot due to the heat. Texas Department of Transportation workers closed the bridge for repairs shortly after and reopened it on Monday evening.
Monday's highs were expected to reach the mid-90s, with light southeast winds. Things were expected to cool down Monday night with lows in the mid-70s under mostly clear skies. The southeast winds should stick around into the night, blowing at around 5 mph.
Tuesday, skies will remain sunny, but highs will creep into the upper 90s, with light winds out of the south. The winds will remain steady into the night with clear skies and lows again in the mid-70s.
The forecast is about the same for the rest of the week, with highs in the upper 90s and lows in the mid- to upper 70s. But with the humidity, it should feel like it's in the 100s, the weather service says.
"Those humidity levels should reach the lower 100s each day after 1 p.m.," said Villanueva.
She said on Friday most cities in the metro area will sit around 99 degrees, but Fort Worth is expected to reach 101.
The temperature should creep up near 100 again on Saturday with humidity levels remaining around 105 until Saturday night, when lows will be in the upper 70s.
It should get up to around 98 on Sunday, but we may get a little bit of relief from the humidity, according to Villanueva.
"The heat index on Sunday will be down a little bit to around 97 or 98," said Villanueva.
