Light snow fell in parts of Western Washington Monday morning, including south Puget Sound, the Chehalis Valley, and parts of Whatcom and San Juan counties.
A weak weather system managed to sneak through a ridge of high pressure and clip the southwestern part of the state with a little moisture and with cold air in place, it was enough to bring a little snow.
Temperatures in the mid 30s prevented anything more than brief slushy accumulations of snow mainly on grassy surfaces in most areas, but in some areas, especially south of Olympia, snow briefly accumulated on roadways, causing spinouts and some minor collisions on Interstate 5, the Washington State Patrol reported. At most, about 1-2 inches were reported.
But the snow tapered off into the afternoon as the system moved south into Oregon and skies were to clear across the region overnight, allowing temperatures to drop into the upper 20s to low 30s with areas of fog.
