Thursday morning’s rainstorm improved the air quality in some parts of Utah a bit, but the effects won’t last. The National Weather Services warns of “degraded air quality and reduced visibility through at least the remainder of the week.”
And, while there's hope that a weekend snowstorm could break up the inversion, that's not a sure thing.
Rain made roads in the Salt Lake area slick, and freezing rains in some areas north of Salt Lake City made roads dangerous on Thursday morning.
