Several feet of snow will fall across parts of the Sierra on Wednesday and Thursday in what will be one of the most powerful storm systems to impact California’s mountains so far this winter. The midweek storm system won’t have an excessive amount of moisture and will qualify only as a weak atmospheric river event. However, an extremely favorable and efficient environment for snow generation will exist in the Sierra over a 36-hour period stretching from Wednesday morning through Thursday evening. … This storm system will also bring snow to the mountains of Southern California. … (B)ut snowpack levels are expected to remain slightly below normal.
