Summary:

High pressure over the eastern Pacific will continue to build toward the west coast through the rest of the week, and persist in some form into the first half of next week, bringing temperatures that are well above normal for this time of year from +5F to +20F.
With enough moisture advecting northward over the region and daytime heating, look for the potential of very scattered showers and thunderstorms over the southern Sierra, far southern CA, and southern NV this Friday and weekend.
Rivers will slowly continue to decrease towards baseflow conditions throughout much of the area.
A few high elevation basins will see minor rises from increased snowmelt.

Confidence: High

Staffing Level: Normal
