As the northwest eagerly awaits some dry time, it's going to come at another's expense. California will be the next in line to pick up heavy rain and snow looking ahead, as the pattern doesn't change, it merely moves.
Areas up and down the Sierra Nevada Mountains are in desperate need of snow, though. This year, we've picked up around 20% of what we normally should by this time of year. We'll try to change that going into the next few days. As the firehose drops south late this week into the weekend, rain will initially be the biggest concern. Snow levels will struggle to get all the way down to pass level at first, with this being a bit of a warm system.
But moving into the weekend, the snow levels will drop. But the best moisture might ultimately end up in the southern portion of the mountain range.
Heavy, persistent rain will be the greatest threat going into the weekend, as it may not let up before rolling into the holiday travel week. By then, some areas could be staring down rainfall totals surpassing a FOOT!

This is a ways away, however, so be sure to check back with the forecast as we grow closer to the weekend.
