A weak weather system will break through the ridge of high pressure on Saturday morning, which could allow light rain to fall, especially in northwestern areas of Washington. Aside from some clouds and light southwesterly breezes, the impacts of the disturbance should be minimal, although the increased mixing from Chinook winds may lead to a very warm day in central Washington. Slightly cooler and drier continental air is likely to clip eastern Washington early next week, as a sharper ridge builds near the coast. The brief period of northerly flow is not expected to significantly affect the weather, although a few frosty nights are possible early next week in eastern areas. Any cooling that occurs will simply bring temperatures from well above normal to somewhat above normal.

As the ridge shifts inland next week, warmer day-time weather should follow, along with continued dry and fairly calm conditions. The weather conditions for later next week and next weekend are uncertain, with a variety of potential solutions. It appears that another weak system will pass through Washington later next week, before high pressure rebuilds and leads to more dry and mild conditions for next weekend and beyond.
