We'll see. The day-ahead estimates have been high all week, and the temperature is dropping tomorrow. I put it about a 50/50 chance that we break 50GW tomorrow.
Maybe in parts of the state, but all over northern CA there are places forecasting a few degrees warmer. Plus the overnight will be high enough that buildings won’t lose as much retained heat, and will start out slightly warmer.
I underestimated the heat in northern California extending past the initial wave.
