Watch water pour out of Fair Oaks' Nimbus Dam after heavy rains
A pair of weather systems from the Gulf of Alaska are expected to cool the Sacramento Valley and bring light rain after a balmy start to the week Monday.
About a quarter-inch of rain is predicted to fall Tuesday through Thursday, the majority of which will come down Wednesday night. Snow levels should tumble from 8,000 to 3,000 feet as around six inches of powder drops in the Sierra Nevada mountains by Thursday morning.
Monday calls for dry skies and highs near 80 degrees, and National Weather Service meteorologist Jim Mathews anticipates the work week will end on a similar note. The cold weather system will drop peak temperatures to the upper 60s Tuesday and Wednesday and to the low 60s Thursday.
Several outlying areas of Sacramento County got two to three inches of rain from last Thursday through last Saturday morning, and Sacramento Executive Airport reported 2.42 inches during that time. The majority of collection points within city limits saw an inch-and-a-half to two inches, while up to seven inches of rain but virtually no snow fell in the mountains. Meters at Sacramento State and Oroville both received record highs for April 6.
The Northern Sierras' eight-station precipitation index is up to 84 percent of year-to-date average after a weak start to the wet season. State officials considered testing the Oroville Dam's partially rebuilt spillway last weekend but ultimately didn't need to, as water levels stayed 30 feet below the "trigger elevation."
More light showers could make their way into the region next Sunday night through Monday morning as a cold system hits the Pacific Northwest and California's North Coast.
