A winter weather advisory for 2 to 4 inches of snow in the Spokane and Coeur d’Alene area was issued this morning with the snowfall arriving tonight and Wednesday morning.
Snow amounts were upgraded to 3.6 inches in Spokane and 3.8 inches in Coeur d’Alene.
Pullman could 2.9 inches and Sandpoint, 2.6 inches.
Heavy snow of 8 to 12 inches could fall in the mountains of North Idaho to the east of St. Maries and Moscow. A stronger winter storm is in effect for southern and eastern portions of Kootenai County, Shoshone County and parts of Benewah and Latah counties.
The winter weather advisory was expanded to most of Eastern Washington.
Precipitation could arrive as early as 7 p.m. and last until noon on Wednesday. The heaviest accumulations are likely before dawn.
The morning commute could be a challenge with a fresh layer of snow and ice, forecasters warned. Interstate 90 between Spokane and Coeur d’Alene could become challenging, they said.
A sagging cold front combined with an upper-level low pressure area from the Gulf of Alaska could bring periods of heavier snow across eastern Spokane County, Kootenai County and Palouse as well as the mountains to the east.
Southern Kootenai County could see a half foot of snow.
Looking ahead, snow showers remain in the forecast through the week with lows going into the 20s on Wednesday, Thursday and Friday with highs in the 30s. Another pair of storms is likely on Saturday and again late Sunday with temperatures running in the middle 30s during the day and lower 30s at night.
