It’s officially summer in North Texas

The last couple weeks have really started to feel like summer in North Texas and now it’s officially here.

Monday’s temperature should reach 95 with the heat index bringing it up to 99 later this afternoon. The hottest it’s reached on the first day of summer was 104 in 1953, according to the National Weather Service. The average first 100-degree day in DFW is July 1, the weather service says.

The weather service issued an air quality alert for today. Atmospheric conditions are expected to be favorable for producing high levels of ozone, according to the NWS website.

Light winds at the surface and in the atmosphere aren’t strong enough to disperse the pollution the Metroplex creates, allowing it to pool over the area, weather service meteorologist Dennis Cain said.

Sharing a ride, walking, riding a bicycle, avoiding drive-through lanes and keeping vehicles properly tuned are all ways to keep from contributing to pollution, according to the NWS website.

Most areas will remain dry but there’s a slight chance of an isolated shower or thunderstorm later, according to the forecast.

Tuesday’s high should reach 97 and the heat index could climb up over 100 again. The rest of the week looks clear and dry with humidity levels dropping and highs hovering around the mid- to upper-90s.
