If you thought this was a relatively cool year in Utah, you are right, but only in terms of the recent climate. The statewide average temperature for Utah in 2010 was 48.9F. This makes it the second coolest year (after 2009) since 1993, so it certainly seemed cool for recent Utah transplants or native Utahns who are short in the tooth. Those with a longer memory might have a different perspective as 2010 was still a full degree warmer than the long term average for the 20th century (47.9F).
One thing I would like to see done with the Utah temperature records is an analysis of how persistent wintertime cold pools in valleys and basins affect the long-term tend and year-to-year variability. This could include an analysis of the frequency and intensity of those cold pools. I suspect one would find differences between in valley/basin locations where these cold pools are common, and mountain locations where these cold pools are infrequent.
