The first low pressure center has already pushed away from the Rockies and into the Great Lakes. A second low is moving southward out of Canada into the Northwest, funneling up moisture from the Pacific Ocean. This will help to produce areas of heavy snow, along with strong, gusty winds. Snow will spread to the east and south into tonight (Wednesday). High pressure will build across the West Thursday, giving the region a break from snowfall.
