Friday Nov. 27
Snow flurries and very light snow showers will continue today and Saturday in the Sierra, especially the Eastern Sierra and the Sierra front in Nevada. The low pressure system that brought about a foot of snow to the peaks above Tahoe this week is still hanging around over the Great Basin, with it western edge still capable of bringing us snow. Additional accumulations will be scant, however.
That system should exit the region altogether by Sunday, and while there is a chance of a brush-by from a modest storm on Monday, we have our eyes on the next big low pressure system brewing over the Pacific. This one is likely to approach California on Wednesday and perhaps reach the Sierra by Thursday.
With all the talk of this being a strong El Nino year, none of the recent storms have really had a sub-tropical influence, which is the kind of thing you expect in a Nino season. They've been more typical Gulf Of Alaska-spawned cold but fairly dry low pressure systems.
But the storm on the horizon looks warmer and poised to tap into a significant moisture plume over the Central Pacific. If it reaches us, look for temperatures -- and snow levels -- to be higher, between 6000 and 8000 feet, at least to start. And the system will be packing more moisture, so precipitation totals would be higher.
Right now the storm's trajectory is still uncertain, so we may in the end not get a direct punch. But if it does come our way, it will feel a lot more like an El Nino year than it has so far. Warmer and wetter. Let's hope it stays cold enough to bring snow to the mountain passes and below...
