West Coast Outdoor Weather 12-10-2015  The Washington Cascades can expect some moderate precipitation at times for this weekend with some locations in the West Cascades getting up to 3 inches (cumulative) in water equivalent. However for part of Saturday snow levels increase briefly to about 5000 to 6000 feet but slowly lower to 2500 by later on Sunday. Thus on Sunday new snow of about 20 inches in some places at 3500/4000 feet.
For much of the Northern Sierra (Lake Tahoe and north) some light snow on Saturday especially for the north with heavy snow for much of the Sierra on Sunday with over 20 inches at 4000 feet. This is from a deep trough of low pressure that moves inland (see map below).
