Looking west down Little Cottonwood Canyon @ 2:37 PM MST 1 Jan 2013. Click to enlarge. |
The deep valley cold pool is actually a good thing. During bad inversion events, the inversion is located very near the valley floor and all our pollution is confined to a very shallow layer. Today, however, the inversion was located about 3000 feet above the valley floor, which is why there are stratus clouds tonguing so far up Little Cottonwood. That means our pollution is being distributed through a deeper layer. Unfortunately, the inversion will be lower and the air pollution worse later this week.
Also, there's not much hope for snow in the 7-day forecast. Time to start appeasing the gods...
