A Pleasant June So Far (By Recent Standards)

The average temperature at the Salt Lake City International Airport for the first three weeks of June was 68.9˚F.  This is quite comparable to the first three weeks of last June (68.6˚F) and considerably cooler than the first three weeks of June 2015, 2016, 2017, and 2018, when mean temperatures were at or above 74˚F.

So, compared to recent standards, this has been a pretty nice June.  However, it's still about 2.4˚F warmer than the 20th century average for Salt Lake City.

It's also been a June of extremes.  Just check out the roller coaster we've been on below.  We hit 100 on June 5, the earliest 100 ever recorded at the airport, then plunged downward with highs of 60 and 55 just 2 and 3 days later, respectively.  We subsequently seen big swings continue through today.

Today looks splendid with a high of 84 forecast for the Salt Lake City Airport by the National Weather Service.  Temperatures will climb into the low 90s by Wednesday, but then another trough moves in on Thursday.  The GFS forecast for late Thursday afternoon (MDT) shows the trough over northern Utah bringing a chance of showers and thunderstorms.  Hooray!


Climatologically, we are entering the least synoptically active part of the year, so each trough we see now is a blessing.

  2. Any idea of the development of our summer monsoon? I assume, while the troughing in the west has been a nice surprise for June, it hinders the development

    1. Nobody knows. The climate prediction center currently rates the precip chances for the southwest as "equal" for July, meaning no weighting relative to climatology. Northern Utah is very slightly weighted to drier than average, but not enough to count on anything. Basically, there's nothing to indicate things going one way or the other.
