Big Low-pressure rotates moisture inland in pulses, with plenty of clouds & showers each day, Friday through Sunday. Expect periods of heavier rainfall, and just a few breaks in the clouds & showers.

Also, much cold air is coming inland, cold enough in Jackson Hole for the possibility of some snow to the valley floor.

Another Low-pressure center in the Gulf of Alaska will be moving inland later Sunday and affecting the weather across the Western U.S. for most of next week, keeping it wet & cool.
