You can look at the timeframe from 10/1 to 10/3 to see how the remnants of a late season hurricane passing through the desert can disrupt a stable non-monsoon weather pattern.
From about 9/27 to 10/1, we see the typical non-monsoon cycle recover after the 9/19 monsoon event. The hurricane event on 10/1 throws this pattern into disarray and it still hasn’t recovered. Note the difference in the luminosity data, temperature, and pressure.
