Black Friday

Wasangelas and the Oquirrh Mountains.  Tuesday November 27, 2013
I was curious how the Thanksgiving day holiday would affect air quality in the Salt Lake Valley.  Answer: Not much.  PM2.5 levels continued to climb yesterday, with hourly averages peaking at 42 ug/m3 late yesterday and 24-h averages continuing to climb to 27 ug/m3.

Thus, Black Friday is aptly named this year.  There is a weak trough pushing into northern Utah for the weekend.  Hopefully it will stir things up a bit and provide some relief for the valley before the holiday weekend comes to a conclusion.  If not, there's always the mountains.  

Personally, I feel fortunate to be out of town and breathing the cleanest air on Earth in southeast Alaska.  It is the rainy season here, but the car-wash-like conditions let up just enough to allow us to take a beautiful hike before overindulging on turkey and trimmings.  Happy belated Thanksgiving.


  1. Is that a landslide? Or are they logging? Or is that disease? I'm so confused

  2. -17 F here on the Kenai Peninsula. Can't beat Alaska for scenery for the ten minutes you can stand to be outside.
