Salt Lake City experiences dense air inversion due to fog, meteorologist explains

Last weekend, Salt Lake County experienced a dense air inversion, but it was primarily due to fog rather than pollution. Meteorologist Michael Wessler noted that air quality remained stable compared to earlier in the week. Inversions occur when cold air is trapped in valleys by warmer air above, leading to stagnant conditions. Wessler explained that moisture can condense, creating fog, which was evident last weekend. The absence of snow helped prevent more severe air quality issues. Following the inversion, a weather system moved in, clearing much of the stagnant air. Wessler indicated that similar conditions could occur again, especially if inversions last longer, leading to increased fog and pollution buildup.
