The warm-up will continue through the week with highs returning to the 70s by the end of the week.

The 1980 Mount St. Helens eruption remains the deadliest in U.S. history, fundamentally changing how scientists monitor volcanic activity.

Morning fog and clouds will begin Monday morning, but sunbreaks will rule the afternoon.  The high pressure ridge will continue to keep skies dry across the region with just a few passing clouds.

Saturday's showers and isolated storms will wrap up by overnight as the cold low exits Western Washington.  Skies will start off foggy Sunday morning with sunbreaks by the afternoon. 

While it will be a cool and wet start to the weekend, Sunday is looking much better. Skies will begin drying out with a nice warm-up throughout next week, nearing 70 again by Friday.

While thunderstorms can develop almost anytime Saturday — including during the morning or midday hours — the overall thunder potential will likely be slightly higher compared to Friday

A pair of weather systems will sweep through western Washington on Friday and Saturday, bringing widespread showers, breezy conditions, isolated thunderstorms and temperatures that will feel more like early April than mid-May.
