Heavy Snow Warnings issued across Inland Northwest

Posted: Updated:

Heavy snow warnings have been issued for much of Eastern Washington and Northern Idaho. The Spokane County Sheriff's Office is asking that drivers avoid traveling on the roads if possible due to dangerous conditions.

A heavy snow warning is in effect until 10 p.m. PT this evening for the Coeur D'Alene, Upper Columbia Basin, and Spokane areas.

Sloppy conditions accompany the snowfall in Spokane as afternoon temperatures hover near the freezing mark. As a result, minimal accumulations due to melting can be found in the downtown and valley locations. Most significant snowfall amounts above 2 inches (and sticking) are in the higher surrounding areas of the West Plains, Deer Park, and Coeur D'Alene.

Expect most snowfall to end near midnight tonight after topping out near 3-4 inches total, but thereafter, ice may become the greatest hazard. Temperatures will drop below freezing quickly and any untreated roadways will form a treacherous layer of ice. Tomorrow's temperatures are forecast below freezing, so thawing will be minimal, especially on secondary and shaded roadway.

A winter storm warning is also in effect from 1 p.m. this afternoon to 10 a.m. PST Monday for the North Idaho Panhandle, Central Panhandle Mountains, and Northeast Mountains.

5 to 9 inches of snow is likely to accumulate in these areas by Monday morning. Nearby mountains will receive 10 to 18 inches of snow. The heaviest snow will occur overnight, but travel through the passes may be treacherous as early as late afternoon today.

Heavy snow will develop over the mountains of Northeast Washington as well as the mountains of the Idaho Panhandle today and a significant portion of the lowlands of Eastern Washington and Northern Idaho. The heaviest snow accumulations will occur this afternoon and overnight tonight.

Cold air will move in behind this system next week, with morning low temperatures likely dropping below zero in many areas Tuesday and Wednesday night with wind chill readings as cold as -20 fahrenheit and colder in some locations Tuesday night into Wednesday morning.
