A weak cold front will move across the area tonight. There's a slight chance of snow along the Idaho border and in SW Wyoming. Light snow is possible over the Northern Mountains, but without much if any accumulation. The front could weaken the inversion and bring better air quality for a day or two along the Wasatch Front.
