Cold and a little snow headed to South Sound

A cold front is moving into Western Washington and could bring about 1 inch of snow to the lowlands through Saturday.

But what most people will notice is the cold. After this week’s unseasonably balmy temperatures, lows Saturday and Sunday are forecast for 23 degrees in Olympia and a few degrees colder farther inland.

A light dusting of snow — up to a half inch — could fall Friday night and again Saturday morning, but will likely clear before 11 a.m. Saturday, according to the National Weather Service.

As the cold front sweeps through, the snow level should drop to about 300 feet. According to the weather service, the area likely to receive the most snow is north Puget Sound, where the arctic front will add to convergence zone precipitation. About 3 inches is possible there, with 1 inch or less across the rest of the interior.

By Saturday afternoon, skies should clear and the sun might even make an appearance, according to the weather service. Daytime highs this weekend will be around 36 degrees. The longer-term forecast predicts temperatures slowly moderating.

Heavy rain Friday prompted flood watches and warnings, mostly north of Seattle. The Skokomish River flooded some roads in Mason County.
