You might actually want to keep your mask on outside today! High pressure is still maintaining an inversion, so air quality will continue to be unhealthy for sensitive groups.
A weak storm will brush by Southern Utah tomorrow and might bring a few sprinkles and flurries. Another very weak system might brush by the north on Wednesday.
Stagnant air will linger through most of the week with poor air quality expected. But a stronger storm is expected to move through on Friday, which might break up the inversion and scour out most of the smog.
