Lets not forget the white stuff

A wet, active pattern will continue for the West over the next few days, particularly near northern California. A pair of low pressure systems move into the West early Thursday and late Friday. Heavy snowfall across the Sierra Nevada is expected above 4,000 feet, with localized amounts of up to 3 feet by Friday morning, which has prompted winter storm warnings.
