Updated: 3:30 PM PST on November 12, 2009

Mostly cloudy. Chance of a rain or snow shower. Lows in the upper 20s to mid 30s. Northwest wind 10 to 15 mph decreasing to 10 mph or less after midnight.
Saturday
Partly sunny. Highs in the 40s. South wind to 10 mph.
A vigorous cold front will pass southeast across western Washington Friday morning... bringing Rain... Mountain snows... locally windy conditions and possibly snow showers to parts of The Lowlands.
South winds in advance of the front will increase late tonight into early Friday morning... mainly along the coast and parts of the northwest interior including the Admiralty Inlet region. Wind speeds in those areas are expected to reach 20 to 30 mph with a few gusts to 45 mph... mainly in and around the Island County area. After the front passes... winds will become west to southwest down the Strait of Juan de Fuca and across the northwest interior before diminishing through the afternoon. While below Wind Advisory criteria... wind of this strength could blow down a few tree limbs here and there with isolated power outages.
Colder air will surge in behind the front and lower already low snow levels across the region. During the morning hours ahead of the front the snow level will be around 1500 to 2000 feet. The snow level will then gradually drop through the day to around 500 feet by evening. This means some of the highest hills around the region could see a few snow showers late Friday into Friday evening. However... outside of the mountains or the immediate Cascade foothills... little to no snow accumulation is expected.
Dry and tranquil weather will return to the region late Friday night into Saturday.
