This is going to be a benign weekend with little weather action. We are in a pattern where the storms are deflected towards California and we get some weak cloud bands on their northern side. Today is a case in point....with the visible satellite picture showing the situation (see image). This morning the Cascades were really clear due to easterly flow sinking along the western slopes of the mountains (easterly flow causes drying of the air as it descends). There were also lots of mountain wave clouds.
So in the lowlands there should be temps in the mid to upper 40s for the weekend, with partial sun. The mountains will get some occasional snow showers (mainly late Sunday, nothing heavy), with periods of intermittent sun. The snowpack is a stable hardpack now...and plenty icy. I was going to go cross country skiing...but may wait until better conditions occur. The rest of the week looks like more of the same.
The silver lining? California will get the precipitation they really need.
