There may not be much new snow for Utah skiers to grin about this weekend, but at least the rest of us in the inversion-plagued valleys of Wasatch Front will be able to breathe more freely.
Wafting in from the Pacific Northwest, a weak storm system was expected to roll in with a cold front beginning Friday night. That will break up the pollution that has shrouded the state's urban valleys since before Christmas, bringing with it "red," or unhealthy air quality.
By Saturday afternoon, most if not all regions of the state should be graded "green" or "yellow," or "healthy" and "moderate" categories, according to the Utah Division of Air Quality. All regions of the state were expected to earn "green" grades by Sunday.
