Life is very different depending on where you are relative to these inversions and stable layers. At the Atwater Study Plot near the base of Alta, which is above the large-scale inversion, overnight temperatures remained at or above 25ºF.
At the University of Utah, which was beneath the large-scale inversion and within the intermediate stable layer, temperatures fell into the mid teens.
At the airport, which was within the shallow nocturnal inversion, temperatures dropped into the low single digits.
This provides a nice example of the complex layering of the atmosphere that sometimes occurs during our inversion events, especially at night. The nocturnal inversion will probably weaken some today, but, thanks to the large-scale inversion, the valley is entirely cut off from the clean air above. And that is the way it will stay through early next week. The models are hinting that a cold front may move through Utah on Wednesday. Let's hope that comes to fruition.
