...Synopsis...
By this weekend, a mid to upper-level shortwave trough will traverse
central CA and the Great Basin. Increasing southwesterly mid-level
flow from the Southwest into the Rockies will accompany this
feature, as the height gradient tightens. Farther east, the
subtropical ridge will begin to expand westward over the southern
and central CONUS into early next week. Pacific mid to upper-level
troughing will continue through this time period as well, leading to
persistent, deep southerly flow developing on the western fringe of
the ridge from CA to the Pacific Northwest.

...D3/Saturday...
Continued mid-level ascent associated with the CA trough will aid in
elevated moist convection developing again from northern NV, far
southeast OR, and southern ID. Projected PWATs D3/Saturday within
this region, combined with receptive fuels and relatively low QPF,
should provide another environment favorable for isolated dry
thunderstorms. Farther south from northwest AZ, into southeast UT,
and far western CO, a deeply mixed boundary layer will allow for
momentum transfer of the stronger flow aloft. Confidence in these
breezy southwest winds developing D3/Saturday has increased enough
to introduce a low probability area for the aforementioned region.
Low RH and increasingly receptive fuels will also be present there.
