It's been a long time since we saw large-scale northwesterly flow (yesterday's intense outflow event doesn't count - it was intense, but a small-scale feature and the winds quickly) but it looks like it is going to happen sometime late tomorrow or tomorrow night. Note the northwesterly flow at 700-mb (crest level) in the GFS forecast valid 1200 AM Monday (see left hand panel).
It will be interesting to see what kind of an airmass this ushers in. Will it be dry and clear, or smoke filled? Time will tell.
If you will miss the monsoonal flow, you can just drive down to southeast Utah. The trough never really pushes into that area and they remain mired in the monsoon.
