Summary:

High pressure continues to reside over the interior of the western US, while lower pressure exists just off the west coast. The southerly flow between the two has increased moisture across CA and NV for the beginning of the week.
Best opportunity for showers and thunderstorms will be today through Wednesday, mainly over the central/southern Sierra and much of the state of NV. A drier airmass will make its way over the region for the latter half of the week, limiting precip to far eastern NV.
Little change in river levels is expected over the next several days.
