Heading back to winter

Our weather pattern is changing.  We are still tracking 2 systems offshore.  The first one will produce rain showers first thing Friday morning.  There is also the chance of thunderstorms.   The real storm of interest swings in Saturday.  Rainfall rates will be increasing. There could also be more thunderstorms. The wet weather pattern remains in place through the weekend. Heaps of snow in the Sierra (over 2 feet) this weekend.  A Winter Storm Warning will be in effect.
