A major winter storm will arrive in northern Utah on Thursday and continue into Saturday, but the good news is that it’s expected to improve air quality.
According to the National Weather Service, a “weakening weather disturbance” will reach the area on Wednesday, with light precipitation in far northern Utah. The storm is not expected to “entirely clear out the urban haze as it passes through.”
PM 2.5 pollution — fine particulates — rose to yellow (or moderate) caution levels in Cache and Weber counties by Wednesday morning, according to the Utah Department of Environmental Quality, and the inversion is expected to worsen there and in other counties.
