Here is my weekly new weather quiz question. What is the “Spring Tide?”
____________
An Upper Level High Pressure Ridge (“Arch” shape) continues moving eastward as Upper Level Low Pressure (“U” shape) takes over. The graphics for days 1-3 show a cold front sliding through Oregon today. The graphics for days 3-7 Thursday through Monday show a frontal system approaching the coast next Monday.
Note: Sorry, my forecast for sunshine after the clouds cleared today just didn’t work out. Cloudy and chilly were the result of Mother Nature’s plan not mine.
