After two days of drying out, forecasters are looking at what the big three-day rain produced and when the next storm might arrive.
A high-pressure ridge is forecast to slide over the West Coast the next few days, bumping up Sacramento’s temperatures to close to 80 degrees. Cooling does not seem to be in the picture until Saturday when a low pressure system arrives.
Meanwhile, the National Weather Service said the storm on Friday through Sunday brought an estimated 5.2 trillion gallons of rainfall to the north state. During an average year, 68.8 trillion gallons of water falls statewide.
However, the weather service notes that much of rain fell along the north coast, which doesn’t significantly contribute to the state’s water supply. Also, as the first big storm of the season, much of the water soaked into the ground left parched by summer.

Sacramento has 2.20 inches of rain in October, nearly all of it arriving in the three-day storm. The mountains also got a good amount of rain, and some snow at the higher elevations.
The heavy Sierra rain resulted in a fairly good increase in the level of Lake Tahoe. The weather service said the rain arriving as an atmospheric river resulted in about a three-inch rise in the lake level – most of it coming from direct rainfall onto the alpine lake rather than runoff into the lake.
The rainfall resulted in an increase of about 33,600 acre-feet – an additional 11 billion gallons. The weather service is predicting that the next precipitation for Northern California will not arrive until early next week when a system moves inland.
