Here is my weekly weather quiz question for the last time. What is a “Tornado Family “? Here is the correct answer. A Tornado Family is a series of tornadoes produced by a single supercell, resulting in damage path segments along the same general line.
____________
An Upper Level High Pressure Ridge (“Arch” shape) is moving toward the Pacific Northwest as the Upper Level Low Pressure leaves.The graphics for days 1-3 show no frontal systems moving into or over Oregon through the period. The graphics for days 3-7 Wednesday through Sunday show surface high pressure through Wednesday, then a complex frontal system slides in Thursday. A complex frontal system will be pushing to the coast Saturday and next Sunday.
