I didn't realize you got those on the west slope of the Sierra, but I guess there are some topographic similarities between the Valley being sandwiched between the Sierra and the Coast Range and the Salt Lake Basin being sandwiched between the Wasatch Range and the Basin and Range highs. I've never seen anything like the inversions in the Salt Lake basin in midwinter. As you note, you can descend from Park City/Parley's Summit (Pass) at +7,000' in the bright sunshine at 40-45 degrees F, and as you penetrate the tan to brown cloud headed west from Parley's, you're in so deep the sun is all but totally blocked out, the air is acrid, and it's 20-25 deg F colder. That can persist for a week to two weeks at most any time in winter.ski3pin said:We are under a persistent high pressure ridge that caps the deep valleys with an inversion layer.
So as we suffer through these agonizing days of clear weather, we woke up this morning to 45 degrees as an overnight low (the high will be 56). Our neighbors below woke to the 20's and 30's.
