Get ready for a cold snap with more chances of lowland snow in Seattle this week.

“We expect a weather system to find its way inland on Thursday and Friday. We expect the center of that system to be south, leaving West Washington in the cold sector of the system. This could go a little further.” Spread lowland snow all over West Washington. But there are still great uncertainties about the strength and trail of the system, “wrote NWS in their briefing on Monday morning.
