Another round of heavy snow continues for the Northwest, adding to the snowpack that is deepening in the region. Ski resorts will welcome the additional snow, but it is another nuisance storm for travelers. Snowfall is already over a foot with this storm in some of the higher elevations. Some mixed precipitation is possible as well into this evening.

The low pressure center and cold front will push through the region tonight and into the Upper Midwest tomorrow. Snow will gradually decrease with this system, but another low at the end of the week will produce another round of snow for the region.
