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 no frontal activity through the period until a cold front will be offshore Sunday. The graphics for days 3-7 Tuesday through Saturday show a cold front moving through between Tuesday and Wednesday.
