- A weekend storm brought heavy snow and rain to Northern California.
- Snowfall in the Sierra Nevada reached up to three feet in some areas.
- Valley rain improved seasonal water totals but caused localized flooding.
- A rare tornado touched down in Tehama County during the storm.
Monday, April 13, 2026 –– A powerful spring storm swept across Northern California this weekend, delivering a mix of heavy snow, soaking rain, and even a rare tornado. According to reporting from multiple sources, the storm created both welcome relief for water supplies and dangerous conditions across the region.
In the Sierra Nevada, snowfall totals were especially impressive. Resorts and high-elevation areas reported significant accumulation, with Palisades Tahoe receiving nearly three feet of snow. Other mountain locations, including Carson Pass and Heavenly Valley, saw around two feet, while areas like Truckee recorded about 16 inches. Additional reports from the California-Nevada River Forecast Center, cited by the Sacramento Bee
, showed widespread snowfall exceeding a foot in several counties, including Alpine, Placer, and El Dorado.
Rain Brings Relief, But Also Flood Risks.
Lower elevations saw steady rainfall, helping improve water-year totals. Valley cities like Sacramento recorded about 1.3 inches of rain, while Stockton and Modesto also received measurable gains. These totals pushed Stockton to roughly 112 percent of normal for the season and Modesto to 109 percent, according to KCRA reporting.
In the foothills, however, the storm’s intensity raised concerns. Some communities received more than four inches of rain, prompting flood advisories over the weekend. While most valley areas handled the rainfall without major disruption, localized flooding highlighted how quickly conditions can shift during strong spring systems.
Snowpack Gains Come at a Critical Time.
The Sierra snowpack plays a key role in California’s water supply, acting as a natural reservoir that melts gradually through spring and summer. This late-season storm provided a meaningful boost at a time when water managers closely track every inch of snow.
Even so, experts often caution that a single storm, no matter how strong, does not erase long-term concerns about drought, variability, and declining snowpack trends across the West.
Tornado Adds to the Unusual Weather Mix.
As if heavy snow and rain were not enough, the storm system also produced a tornado in Tehama County. According to Weather.com coverage, the twister touched down during the same system that blanketed the Sierra, underscoring the event’s unusual and volatile nature.
A Reminder of Extremes.
By early April 13, 2026, conditions were beginning to improve in the valleys, though lingering snow showers continued in the mountains. The storm served as a reminder of how quickly weather patterns can shift in California, bringing both relief and disruption in a matter of hours.
For water watchers across the West, the takeaway is clear. The boost to snowpack and rainfall is welcome, but the broader challenges tied to long-term water supply remain firmly in place.
