As the ridge of high pressure over Washington temporarily weakens, a couple of anemic disturbances will pass through the state this weekend. Some clouds and light precipitation are possible, although the overall impacts should be minimal. Alas, the ridge is likely to rebound next week, which should encourage a resumption of dry and fairly calm conditions. Temperatures are expected to be relatively mild, especially for the mountains and coast, although low clouds could re-develop in the interior lowlands as inversions strengthen next week.

A pattern shift may occur starting around next Thursday or Friday, as a moist Pacific jet takes aim on Washington. Increasingly wet and stormy weather is possible at that time, although temperatures should actually warm further in the eastern lowlands due to the increased mixing and mild southwesterly air flow.

  • Becoming warmer later next week.
