It's Going to Be Close

Utah has not has a year with a statewide average temperature below that of the 20th century mean since 1993.

That is quite a run and it reflects a warming climate.

However, so far this year is very close to that 20th century mean, so the next several weeks will determine if the streak will continue.  In northern Utah, we had a remarkably cold January followed by a remarkably hot summer.  The extremes in southern Utah haven't been quite so pronounced.  When you put all of this together, the statewide average temperature for January–September is just a shade (< 1ºF) above the mean for the same period during the 20th century.

If we can eke it out, that would give us 20 consecutive years with statewide average temperatures above the 20th century mean.  If Utah's climate wasn't changing and remained equivalent to that of the 20th century, the odds of that occurring are about 1 in a million (basically, the same as flipping a coin and getting a head 20 times in a row).  Such a long run of above average annual temperatures is yet another indicator that the climate of the past couple of decades is not the same experienced by Utah residents during most of the 20th century.
