SALT LAKE CITY — A change in the weather over the next few days is expected to improve air quality across the state.

Skies have been hazy across the Wasatch Front in recent days.

"We've had some smoke from some fires, especially in Nevada, but also elsewhere surrounding the state," Donna Spangler with the Division of Air Quality said.

But things are improving.

"We have a cloud cover, and it's helping improve the air quality tremendously," Spangler said.

Cooler temperatures and thunderstorms are expected over the next few days throughout the state, KSL meteorologist Grant Weyman said.

For the Wasatch Front, temperatures Friday will be in the high 80s and scattered storms are expected through the weekend. Storms are also expected during the next couple of days in the St. George area.

Air quality throughout the state will go from moderate to good by the weekend, according to the Utah Department of Environmental Quality.

The much-needed rain could also increase the risk of flooding and wildfires due to lightning.
