While there were no icy thunderstorms last week despite the near-freezing temperatures, snow in Seattle is still a possibility this week.
The National Weather Service (NWS) is currently forecasting snow in lowland areas from Tuesday evening through Wednesday morning when a weather system moves over West Washington.
However, the clusters are expected to remain small and “spotty” – less than an inch for most locations below 500 feet in elevation.
“With cold air in the air and on the surface and falling snow levels, most of West Washington can see some flakes falling on Tuesday evening. With temperatures starting to rise on Wednesday morning, we expect the lowlands for the majority of not much buildup.” , wrote NWS in their briefing on Monday morning.

While there is currently only a 20% chance that lowland areas will accumulate between 1 and 2 inches from Tuesday through Wednesday, areas higher up in the hills and in Whatcom County can see a light dusting of the ground.
There is also a chance of snow falling Friday evening through Saturday morning when a second weather system goes through. Again, snow accumulations are expected to be less than an inch for areas under 500 feet.
The Hood Canal area and Kitsap Peninsula can accumulate between 1 and 3 inches more snow.
As temperatures warm from Saturday afternoon through Sunday, the snow reading rises to 1,500-2,000 feet, ending the lowland snow threat.
“The front system on Friday evening is quickly followed by another weather system on Saturday evening for a relatively wet weekend,” wrote NWS.
