The general theme for the coming outlook period will be more seasonal weather than has been observed recently. This weekend looks to be the most active time in the period, with scattered showers and thunderstorms likely across the state. There will be a renewed chance of showers at times in western Washington after a sunny Monday, although it will be dry for much of next week. Temperatures will continue to be near to slightly below average during the day, especially in western Washington. There will be some day to day fluctuations in temperature and cloud cover as weak weather systems alternate with drier periods in a somewhat non-descript pattern that is neither cool and stormy nor dry and hot. Despite the difficulty in specifying exact details such as the timing of impulses, several things are likely to occur. It will continue to be cooler in western Washington and warmer in eastern Washington, as a strong west to east temperature gradient continues across the state, although extreme temperatures do not appear likely. Monday looks to be a warm and dry day, with a chance of showers returning to western Washington for Tuesday. It appears now that warmer and drier conditions may return later next week.

There will be a chance of showers or thunderstorms east of the Cascades this weekend, with generally seasonal temperatures and moderate humidity. Next week will feature mainly dry conditions and low humidity, with seasonal conditions continuing. It appears that Monday will be a sunny and warmer period, potentially followed by a few clouds and breezy conditions associated with a dry cold frontal passage around Tuesday.

Showers are likely on Saturday in western Washington, as onshore flow continues to provide slightly below normal day-time temperatures. Sunday will see a decreasing chance of showers and possible clearing. Monday will be sunny and warmer, with increasing clouds overnight, as another system impacts the region by Tuesday.
