Summary:

Strong high pressure continues to encompass the country with the axis over the Plains states. Low pressure resides off the coast of the Pacific Northwest, bringing a drier airmass over the region, which will keep any precip over eastern NV and southeast CA through Friday.
As the area of high pressure builds a bit westward this weekend into early next week, flow turning more southerly will return a chance of precip to the Sierra for this weekend into early next week.
Runoff into rivers will remain steady over the next several days.
Rio Vista is forecast to exceed monitor stage during peak high tide.
