The weather will be wet at times in western Washington, but mostly dry conditions will prevail in central Washington for the next seven days. And although weak to moderate strength storms will affect Washington periodically through the middle of next week, the weather will not be nearly as active as it has been for the last ten days. Temperatures will be above average, and there is no chance for arctic cold or significant lowland snowfall through at least next weekend.

Saturday will be dry for most places, and Sunday will be dry in central Washington. Rain returns to western Washington beginning on Saturday night, and then rain becomes likely by Sunday evening for areas from Walla Walla eastward to Pullman. Downsloping westerly winds will cause temperatures to hold steady or rise in central Washington on Saturday night and into Sunday morning.

High pressure is likely to gain control of the weather by late next week, which should bring a period of mild and generally dry conditions to the region. While the high pressure ridge in early to mid December led to cold lowland conditions, it appears that Washington will be on the warm side of the coming early February ridge of high pressure.
