Periodic storm systems will bring rain to western Washington beginning this weekend and continuing into next week. A weak and somewhat cool weather system on Christmas Day will bring some rain to western Washington and rain and snow to the mountains. A series of slightly stronger, wetter, and warmer systems will bring rain at times to areas from the Cascades westward for the remainder of the week. Eastern Washington will likely see some rain next week, while there will be a chance of rain at times even in the lee of Cascades in central Washington. Temperatures in the lowlands will trend to above normal by next Tuesday and Wednesday, especially in the Walla Walla area. A mild southwesterly air flow from the Pacific Ocean will bring stronger winds and increased atmospheric mixing to Washington as compared to earlier this month.
