A trough of low pressure is poised to move over the Pacific Northwest over the next several days, and we can expect a rapid weather pattern change. Temperatures will drop and the wind will get stronger for most areas. Tonight will be a fairly quiet night with light breezes, areas of smoke and seasonable temperatures. Lows will range from the 30s and 40s in the mountains to the 50s and 60s in the foothills and valley. Thursday will be a mostly sunny to partly cloudy day with areas of smoke and stronger wind gusts in the afternoon and evening. Highs will be cooler, ranging from the upper 70s to the upper 80s from the mountains to the foothills and valley.
The trough which will move over our region Thursday through Saturday will also bring a slight chance for light rain showers and thunderstorms, but unfortunately there aren't any good chances for widespread, wetting rain for our area. We can expect stronger wind than we want late Thursday through early Saturday before the trough exits to the east. A small ridge will bring more sun and a little more warmth Sunday before another weaker trough brings a few more clouds and breezes Monday. Tuesday and Wednesday will be a seasonably warm start to the new fall season. Highs will be mainly in the 80s throught next week with a few upper 70s and lower 90s.
