Summary:

An area of low pressure will impact the region later today through Sunday with the best chances of precip across northern/central CA and the northern half of NV. Chances of thunderstorms in the afternoons/evenings as well.

Amounts will range from 0.10" to 1.50" with the best totals over the northern CA higher terrain.

Temperatures will crash by the end of the week to well below normal for this time of year with many locations bottoming out either Saturday or Sunday with anomalies of -10F to -25F.
High pressure builds in offshore early next week allowing temperatures to rebound and conditions to dry out for most areas.
Runoff in most snow-driven basins is expected to taper off over the next few days with increases expected again next week. Most other locations should remain steady or continue receding.
Sprague River @ Beatty (Oregon) is expected to remain near or above action stage for the next several days.
The Sacramento River at Rio Vista may briefly reach monitor stage early next week at high-high tide.
