LONG TERM...Tuesday through Saturday

Two cut off lows will move onto the West Coast on Tuesday. Our region looks to be sandwiched between these two cold air masses, which will bring showers to high terrain and near the Nevada border through Wednesday. Model agreement amongst solutions remains high in the overall track of the systems, but some variation exists on the position of the southern low, so uncertainty remains in precipitation and temperature forecasts through Wednesday. Snow levels will likely be around 5000- 6000 feet MSL through Wednesday, briefly lowering to 3500-4500 feet MSL on Thursday with low elevation rain-snow mix possible Thursday morning.

A ridge looks to build back in briefly to our area on Thursday ahead of another trough digging into the Pacific Northwest from the Bering Sea. An unsettled pattern will continue through Saturday, with yet another cutoff low moving into California and diving to our south. More uncertainty follows this system, with several models varying on positioning. This will likely bring another push of precipitation, with potentially cooler temperatures bringing lower snow levels to the area on Friday and Saturday.
