Air quality is much better behind a cold front that moved across Utah yesterday. High pressure building back in will keep it cool and dry for the rest of the work week. Valley inversions will start to develop again later in the week, but a dry cold front will move in late Friday into early Saturday. That will help to weaken the inversions and limit any haze that might start to build.
