Eastern Washington will likely experience isolated to scattered frost on Saturday morning, as a few cold locations dip below the freezing mark. As a quick moving weather system passes through Washington later in the day, rain showers are likely in western areas. Meanwhile, eastern areas will become quite breezy in the afternoon, although most locations should stay dry.

A trough of low pressure will approach Washington early next week, before eventually passing through the state by Wednesday. As a result, warm and dry conditions early on Monday will yield to much cooler and damper days by mid week, especially in areas like Pullman and Spokane. Due to the expected unstable southerly flow on Monday and Tuesday, isolated thunderstorms will be possible during the transition from mild to cooler weather. In any event, numerous rain showers will be possible statewide on Tuesday and perhaps Wednesday. Variably active weather is likely to persist during the latter part of next week and into next weekend as well.
