Here is my new weekly weather quiz question. “What is the “QPf Discussion?”
__________
An Upper Level High Pressure Ridge (“Arch” shape) is still keeping the warmer and dry weather over us. The ridge starts moving away from us by Tuesday. The graphics for days 1-3 show no frontal systems approaching the Pacific Coast. The graphics for days 3-7 Thursday through Monday show the frontal system that pushed through the Pacific Northwest Wednesday and next one moves in Saturday.
Note: The Vernal Equinox takes place this Tuesday March 19th at 8:06 pm to begin the season of Spring.
