We are so desperate for weather that I feel the need to mention that there is actually a weak short-wave trough dropping down the back (eastern) side of the ridge and passing through our area Wednesday night.
Yup, that's your weather for the week. It will bring somewhat cooler temperatures to the mountains, perhaps helping with the snowmaking efforts and might stir the upper part of the inversion a bit. Emphasis on might. Low elevations will likely remained mired in pollution.
I am a bit more optimistic that the trough on Saturday is strong enough to give us at least a partial mix out. It's still soon to say if it will scour it all out. Sometimes, the coldest, most polluted air at the lowest elevations can be quite stingy.
Snowfall totals for the mountains presently look paltry. About half the members in our downscaled NAEFS ensemble generate 2 inches or less. A few members go for more. A game changer is unlikely.

Thus, hope we get something from the trough on Saturday and at minimum hope it cracks the inversion. It's the only slim hope we have for mountain snow over the next week. After that, your guess is as good as mine.
