How Much Will It Snow In Sammamish-Issaquah? Here's The Forecast

SAMMAMISH, WA — A new chill is in the air, and snowy weather is barreling fast toward Puget Sound. The first flakes fell Thursday morning, with some accumulation along the Olympic Peninsula and an early dusting for towns south of Olympia. Forecasters expect the storm to move northward into Thursday evening, propelled by frigid winds and bringing 1 or 2 inches of snow to Pierce County overnight.

The first round of snow should have limited impacts for King County and other points north, with under an inch forecast for Seattle and Everett. But snow fans should not lose faith: the main event premieres Friday.

Most communities wake up to morning lows in the teens, and afternoon highs are unlikely to escape the 30s. East winds will add even more to the chill. The unusually cold air will set the table for significant snow.

Adjusted predictions from the National Weather Service show 4 to 6 inches of accumulation for the Seattle area and another 6 to 8 inches around Tacoma between Friday evening and Saturday afternoon.

Here's the snow outlook near you:

Sammamish

• Thursday: Chance of snow early (50%) and likely late, with new accumulations under half an inch.
• Friday: Snow likely after 7 a.m. and increasing into the evening. Forecasts expect 1 to 3 inches of new snow.
• Saturday: Snow continues in the morning, with another 1 to 2 inches of accumulation possible.

Issaquah

• Thursday: Snow likely between 1 p.m. and 2 p.m. and again late at night. New accumulations under half an inch.
• Friday: Snow likely for most of the day and increasing into the evening. Forecasts expect 1 to 3 inches of new snow.
• Saturday: Snow continues in the morning, with another 1 to 2 inches of accumulation possible.

Widespread, heavy snow is likely to continue through Saturday morning, forecasters said, impacting travel across the Puget Sound lowlands.
