Here is my weekly weather quiz question for the last time. What is “Liquid Water Equivalent? ” Here is the correct answer. Water Equivalent is the liquid content of solid precipitation that has accumulated on the ground (snow depth). The accumulation may consist of snow, ice formed by freezing precipitation, freezing liquid precipitation, or ice formed by the refreezing of melted snow.

An Upper Level Low Pressure Trough (“U” shape) is moving eastward and an Upper Level High Pressure Ridge is well offshore slowly heading toward the coast. The graphics for days 1-3 show a weak surface wave moving over the Pacific Northwest Saturday bringing cooler air with it. The graphics for days 3-7 Tuesday through next Saturday show a frontal system moving through Tuesday and Wednesday then another front next Saturday.
