You can tell it’s “Spring Break” because our weather pattern keeps changing. A trough of low pressure (see the blue arrows forming a “U” shape) is drifting eastward. A  frontal system moved through Oregon producing rain. A weak disturbance will move in next. Yet another frontal system will come through on Sunday bringing back the rain chances, so Saturday looks like the only dry day.
