Arriving just in time for the Holiday weekend will be breezy and much cooler weather, as a trough axis crosses the state on Saturday morning. Labor Day is often referred to as the unofficial end of summer, and the unsettled weather should echo that sentiment. While the expected conditions are hardly abnormal for the end of August, it may nonetheless feel chilly to some who have become accustomed to the unrelenting heat of recent months. While isolated showers are likely from the Cascades westward this weekend, most areas should escape with little more than a few clouds. High temperatures on Saturday may struggle to reach 80 degrees even in the warmer parts of central Washington, while lows on Sunday morning may fall into the 40s in some areas.

As high pressure briefly attempts to rebuild across Washington sometime around next Monday, a modest day-time warming trend is likely, as winds die down and lingering clouds vanish. Another weather system may bring cooler air and gusty conditions back to Washington around the middle of next week. However, warmer and calmer weather is likely to return late in the period. Overall, next week's weather should be somewhat variable, although conditions are likely to be rather seasonal.
