The coldest airmass of the season so far is now in place over Utah. A few low temperatures overnight reported to MesoWest are:
Alta-Mt. Baldy: 21˚F
Cardiff-Big Cottonwood: 27˚F
Silver Creek Jct: 30˚F
U of U upper campus: 41˚F
U of U lower campus: 45˚F
KSLC: 47˚F (could be 46)
Sorry to disappoint those of you enamored with cold temps in Peter Sinks, but it only go down to 31˚F there.
As an added bonus, unlike the post-frontal air in recent weeks, this one is quite clean. PM2.5 concentrations are at or below 1 ug/m3 at the U, about as pristine as it gets.
My ride in this morning was brisk. Probably the first day since at least early June that I pulled on the uninsulated but full-fingered gloves.
Speaking of biking, U Bike Week starts on Thursday, Sep 23. There are a number of activities planned including a free breakfast next Thursday, Sep 30. See https://attheu.utah.edu/facultystaff/bike-unity/ for details.
I wish more people rode to campus and have been hoping that the emergence of e-bikes might break down barriers for some. I used to ride my mountain bike to work, but switched to an e-bike a couple of years ago as it made it easier to ride up the hill home in my work clothes. Try one if you haven't already. It's a fun way to commute to the U.
