5 AM on Wednesday: 1-5 inches over the northern Sierra (the pink and black colors) and .5 to 1 inches for much of the remainder of northern CA. We won't escape the rain in the Pacific Northwest, but California will be hit far harder than we.
The wet pattern on Monday and Tuesday is associated with a highly perturbed weather pattern, with a deep low forming over the eastern Pacific (see graphic for 5 AM Tuesday of the upper level flow pattern). The flow (which is parallel to the solid lines) will be strong and from the west/southwest...and headed into northern California.
Good news. The cool, wet pattern should be a memory by next weekend--the models are suggesting a huge high pressure ridge developing over the western U.S. during the second half of the week.
