California faces its most severe winter storm of the season, the 'coldest storm of the season', bringing widespread rain and significant snowfall starting Sunday, February 15th. This system will drench major population centers including Sacramento, Modesto, Merced, Fresno, and San Luis Obispo, with rain totals potentially reaching 1 to 4 inches in valleys and 2 to 6 inches in mountains. Snow levels will plummet to 3,000 feet by Tuesday, increasing risks of travel chaos across the Sierra Nevada, including Lake Tahoe and the Tahoe region, where snowfall is expected through Wednesday. While brief sunshine arrives Thursday and Friday, the storm's arrival will likely disrupt supply chains, strain infrastructure, and impact agriculture in the Central Valley, forcing businesses to prepare for potential delays and operational challenges.
