SEATTLE — Forecasters say the mostly dry spell should continue through Thanksgiving Day in Washington, but the weather will be changing this weekend.
The National Weather Service expects a cooler, wetter pattern Friday and Saturday that will bring heavy snow to the mountains by Sunday evening and Monday. Driving over the Cascade passes may be difficult.
The cold temperatures may bring a chance of snow Monday evening in the Western Washington lowlands.
The changing pattern should clear out stagnant air that’s expected to linger over parts of Eastern Washington into Friday. Then, a chance of valley rain and mountain snow showers is expected through Sunday.
