Weather forecasters say the fog that's been with us for a week will stay one more day on Tuesday before giving way to a weather front bringing rain and warmer temperatures.
Since Wednesday last week, the National Weather Service (NWS) has issued Dense Fog advisories daily and maintained an Air Stagnation warning due to a ridge of high pressure that stayed over Western Washington, trapping the cold and damp air over the Seattle area. According to Scott Sistek at KomoNews.com, the 7-day streak ties for the fifth longest all time (although well behind the "epic fog storm" of December 1985 when the city had 13 straight days with dense fog at some point).
The fog is already starting to break up over Renton on Tuesday afternoon, but the weather will really start to shift tomorrow morning as the fog dissipates and a light breeze and rain start rolling into the area around 4 a.m., according to the NWS 7-day forecast.
Here's the latest forecast for Renton for the rest of the week:
