Several inches of snow are coming to the Snoqualmie Valley this weekend as a winter weather system moves through Western Washington.

The storm is expected to come in several waves, with the first hitting today and marked by temperatures which are expected to reach the mid-20s. Any snow will likely be a dusting on Thursday, but a second larger system is expected on Friday through the weekend, said Jeff Michalski, meteorologist with the National Weather Service Seattle branch.

“Really the North Bend, Snoqualmie area is maybe on the order of an inch or less with this first system, but it’s not over,” he said.

Friday night into Saturday, Snoqualmie could see four to six inches, and North Bend to the east could see six to eight inches.

Snows on Thursday in Puget Sound were largely headed off by a dry eastern wind. However, areas to the south from Olympia to Portland have been receiving significant snowfall.

On Sunday, up to an inch of snow could fall before temperatures rise, turning it into rain. A warmer front is expected early next week that should bump the temperatures back into the 40s.

Snow is in the forecast for local weather expert Cliff Mass as well. On his blog, Mass said he also expects snow in Puget Sound Friday through Saturday. In a post on Feb. 10, he wrote that Seattle could see up to a foot of total snowfall, with 20 inches possible in the south Sound, and nearly a foot in Bellingham. Four feet of snow could fall on the cascades.

In unincorporated King County around the Valley, county crews will be plowing several roads as needed. Several arterials, including SE North Bend Way west of city limits to I-90 will be plowed. A map is available on the county’s snow webpage. However, other roads like SE Reinig Road or SE Mount Si Road are lower priority.

A tweet by the county’s Road Services department said crews are busy pre-treating roads with anti-icer today and overnight.

The county advises that during snow events, residents should be prepared to stay home for several days if conditions are severe. Snow plow routes for North Bend and Snoqualmie are also available online on the websites of the respective cities.

Snoqualmie recently passed an ordinance mandating that residents and businesses whose property is adjacent to city sidewalks must make an effort to keep the sidewalks clear from snow. Residents have up to 48 hours to shovel snow onto the street or de-ice sidewalks. The ordinance can be enforced with a $25 fine after two warnings.

However, those with health conditions, the elderly and people with disabilities are not required to clear their sidewalks.

In North Bend, residents are encouraged to not park on the street or in cul-de-sacs as empty streets are easier for snowplows to clear. The city also advised that snow shoveled from driveways should be placed on the right side facing the street to reduce the chance that snowplows will pile snow in the driveway.
