  • Showers and thunderstorms will increase in coverage across the Sierra crest and points east over much of Nevada, and then down across southeast California. Peak coverage is expected to be Tuesday and Wednesday.
  • High pressure will move downstream from the Four Corners region later in the week, while the upper low pressure just off the northern CA coast will drift northward off the Pacific Northwest coast. This will bring drier southwest flow to the region by the end of the week.
  • Sierra streams are recediing after last week's rainfall.
  • The Sacramento River at Rio Vista will reach monitor stage overnight again tonight with continued high overnight tides through the week. Peak tides are expected to occur August 11-12.
