The front Tuesday looks very weak still, probably looking at only a couple tenths of an inch of rain at best. I have better hopes with the multiple CZ's Tuesday night through Wednesday evening.
12z seems like a reasonable if not somewhat fast way the pattern could unfold, with a seamless three-step retrogression of the (very weak) middle-US ridge, first into the intermountain west with an AR overhead, then the axis drifting right onto the west coast or just offshore producing a heatwave, then out to sea, causing a trough to crash in from the north.
