Here is my weekly weather quiz question for the last time. What is the “Spring Tide?” Here is the correct answer. A Spring Tide is a tide higher than normal which occurs around the time of the new and full moon.
____________
An Upper Level High Pressure Ridge (“Arch” shape) is still heating us up to well above normal temperatures. The graphics for days 1-3 show a frontal system pushing through the Pacific Northwest Monday. The graphics for days 3-7 Wednesday through Sunday show the cold front passed he Pacific Northwest Wednesday.
