Weather Summary
A low-level inversion will continue to bring stagnant air to the Treasure Valley through the rest of the week. This means more valley fog & low clouds, especially from the Ada/Canyon county line west to Ontario and Weiser. Above the inversion, we will continue to see temps from 45°-54° with lots of sunshine each afternoon through Friday.
I expect a strong upper trough to move in on Sunday, breaking the inversion and bringing a chance of snow showers. Colder air will move in on Monday, followed by the start of another inversion on Tuesday.
