Models are all over the place the evolution of this trough as it moves onshore from the Pacific. Looks like they are trending back to a more progressive solution, with the low eventually cutting off but continuing to eject east. Models looked like they might try to cut that low off and slow it down over AZ/NM for a while, but that solution has much less model support now. Looks like there's no issue with moisture return ahead of this trough, so it's more of a where/when things line up as opposed to if.
Those changing model trends keep bouncing it back and forth between rain and snow solutions out here in Utah.
