The valley haze is like an unwanted house guest, it's just going to stick around!
A weak weather system brushing by today will likely keep the inversion from getting any stronger, but it's not going to break it up. The system could also bring some very light snow over the Uinta Mountains and allow some gusty canyon winds to develop in Washington County this evening.
There's a better chance for some stronger storms early next week that might actually break up the inversions and bring cooler, wet weather.
