The unusually dry December weather will continue this weekend and likely for much of next week. Areas of central Washington will continue to have periodic low clouds and poor air quality; however, temperatures in the lowlands will be slightly warmer than during the past week. Although western Washington will have a slight chance of rain early Sunday, conditions will be mostly dry through early next week. Following a weak storm system that will bring a chance of rain to western Washington around the middle of next week, high pressure and dry conditions will return for the end of the week.
