Significant rain and snow are in the forecast for the Golden State, while damp, dreary days are ahead for other parts of the West as signs of El Niño’s influence on the upcoming winter season emerge.
November got off to a wet start across the Pacific Northwest, but the rainy weather didn’t make it south into much of California. Two things will bring a dramatic change to that trend next week: a southward dip in the jet stream the river of fast-moving air that carries storms around the planet will be pointed directly at California; and a large area of disruptive atmospheric energy will linger just off the West Coast.
Next week’s storms will be fueled in part by an atmospheric river – the region’s hallmark type of winter storm, which transports abundant moisture from the tropical Pacific straight to the West Coast.
Rain will push into Northern California as early as Monday, spreading to parts of Central California on Tuesday. The timing for rain in Southern California depends strongly on the exact evolution of the storm early next week, but wet weather will likely commence by late Wednesday or Thursday.
Once rain begins, it will continue at varying intensity for much of the week and into the weekend for some areas. Rainfall amounts are not expected to reach catastrophic levels that would trigger widespread flooding, but many locations could receive more than a month’s worth in a matter of days.
