Summary:

An upper low will meander offshore today and tomorrow resulting in chances of showers and thunderstorms mainly across the higher terrain of N CA, though possible across the N/C Sierra and NE NV as well.
This low will open into a trough and head inland mid week spreading chances of thunderstorms further across N/C CA and into N/E NV. Chances will shift mainly into NV late week.
Above normal temperatures continue today with anomalies away from the coast of +5 to +15 deg F. Gradual cooling throughout the week with more widespread below normal conditions for Friday.
Runoff throughout majority of system is gradually decreasing as soils drain. Some basins above 9,000 ft elevation could see moderately increased runoff due to melting remnants of snowpack.
All forecast points are expected to remain below flood thresholds over the next 5 days.
