At the Salt Lake City International Airport, only 0.26 inches of rain fell in July, compared to an average of 0.72. In August, it was 0.10 compared to an average of 0.76. September? Only 0.19 compared to an average of 1.33. Will it ever rain again?
Data and Methods
I looked at the Global Ensemble Forecast System (GEFS) forecasts for the next week and extrapolated them 7.6 billion years forward to when the Sun will exhaust its fuel and expand as a red giant.
No GEFS members produce precipitation at the Salt Lake City International Airport through 1200 UTC 8 October.
Since there's no precipitation forecast for the next week, extrapolation suggests it will never rain in Salt Lake City ever again.
