It's been a pretty crazy 24-hour period on the meteorological "front." Yesterday's high at KSLC was an incredible 104˚F. Not only is this an all-time record for September, but it is the highest temperature ever reported at KSLC after August 5th. Some colleagues of mine pointed out that this was 4˚F warmer than reported at surrounding sites. I have to concur that the airport highs seem jacked, whether it be instrument or siting characteristics. Nevertheless, 100-102 would still tie or beat the all-time for September, so it remains blisteringly hot for this time of year.
I took the picture below at about 7:20 this morning while mountain biking in the Avenues foothills. Notice anything unusual?
Ha ha. You can't see anything unusual, but the temperatures sure were. I woke up at 6 am and it was 80˚F at my house. 80! Overnight downslope winds in the University of Utah area kept overnight temperatures quite elevated. Surface observations at around 1200 UTC/0600 MDT showed NE flow around campus with temperatures 84-87˚F. Incredible!
