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.

A weak Upper Level High Pressure Ridge(“Arch” shape) offshore keeps the onshore airflow going. The graphics for days 1-3 show a weak cold front moving over the Pacific Northwest Monday and Tuesday. The graphics for days 3-7 Wednesday through next Sunday show a frontal system hanging offshore for most of the week offshore.
