A pattern of weak upper level air flow is likely to continue in the coming days. As an area of low pressure aloft passes through the Pacific Northwest during the Holiday Weekend, unsettled weather is expected east of the Cascades. The movement of the wandering low is still unclear, but periodic showers and even thunderstorms are possible for eastern areas. A band of enhanced rainfall could set up somewhere over Washington this weekend, but its potential region of influence remains uncertain. The low could linger over the state into Monday, but the general trend next week should be toward warmer and sunnier weather.
