We are still really bad at forecasting, especially in western WA. There are so many localized factors that determine what goes on.
Take Stevens for instance. NOAA under-predicts snowfall in the wake of mid-latitude cyclones with astonishing regularity. For whatever reason, their models always fail to fully appreciate the power of convergence combined with orographic lifting.
Baker may also be drawing from a different source than NOAA, like NWAC. They may be producing slightly different forecasts, especially when the area in question is right on the edge of snow level. Different meteorologists may tend to follow different models based on their own personal experience and biases.
Basically, you should do some more research before you talk shit.
