November 21, 2012 9:31 a.m. - Updated: 9:49 a.m.

Thanksgiving holiday travel should be snow and ice free through Friday, but the National Weather Service said some substantial snow may fall today on the east slopes of the Cascades starting at 2,500 feet in elevation.

In addition, the snow level could be as low as 3,500 feet today in the mountains of the Inland Northwest, forecasters said.

A winter weather advisory for 5 to 11 inches of snow is in effect for the east slopes of the Cascades, and the snow could be a problem over Blewett and Loup Loup passes.

It was 33 degrees and snowing this morning at Snoqualmie Pass where traction tires, including all-season tires, are advised.

Lookout Pass on Interstate 90 was reporting wet pavement this morning.

Southwest winds of 20 to 30 mph with gusts to 50 mph are expected today in the lower Columbia Basin, peaking early this afternoon.

Thanksgiving Day should bring a break in precipitation, but valley rain and mountain snow return to the forecast for Friday.

Highs in Spokane will be in the 40s with lows in the 30s.

The weekend forecast calls for a 40 percent chance of rain on Saturday followed by cooler temperatures on Sunday and a 30 percent chance of rain or snow with a high of 38.
