SALT LAKE CITY - Inversion is expected to linger over the Salt Lake Valley throughout the week, impacting air quality until weekend storms relieve Utah's skies.

An incoming temperature inversion will "likely be trapping pollutants at the valley floor" throughout the week, according to KSL Meteorologist Matt Johnson.

Johnson said air quality is expected to enter the yellow and orange zones, meaning Utah's air would be moderate or unhealthy for sensitive groups.

"The Wasatch Front will keep hazy sunshine in the forecast through Wednesday," Johnson said.

Weather models estimate hazy skies would stick around until clouds and an approaching storm move over the valley Friday, which could "help churn things up," Johnson said.

Following Friday's clouds, scattered rain showers and mild snow storms could clear the air Saturday and Sunday as a storm moves in from Southern California.

The National Weather Service Salt Lake City advised some of its services would be out Tuesday due to a planned power outage, and said forecasts and alerts would continue through the National Weather Service Grand Junction.
