1994 is now the third warmest year on record, although I think it carries on as the summer with the most 100 degree days (21). This year we had 11.
In August, this ridge was located a bit west of its mean position for the summer, which contributed to the anomalously high temperatures.
Note also that the ridge had a
positive negative tilt, meaning the ridge axis was aligned from southeast to northwest. This pattern helped keep monsoon moisture from penetrating into northern Utah.
This was an exceptionally warm summer by historical standards, but we will see more like it in the coming decades.
