The National Weather Service said the atmospheric river – which is a “deep moisture plume” moving in over the region – is forecast to bring large amounts of rain to Central and Southern California.
Northern California will be on the northern fringe and will get more moderate precipitation, the agency reported.
Eric Kurth of the National Weather Service’s Sacramento office said during a Monday Webcast that the atmospheric river is expected to bring heavier rain on Wednesday, continuing into Thursday.
Late Thursday and Friday, snow should come down to about 4,000 feet in the region’s higher elevations, with 1 to 2 feet of snow expected in Northern California’s mountain passes, Kurth said.
Lake County’s specific forecast calls for rain Tuesday through Thursday, with a chance of snow showers on Thursday night in some higher elevations.
Chances of showers also are in the forecast Friday and Saturday, and Sunday night, the National Weather Service reported.
Winds also are in the forecast, with gusts of more than 25 miles per hour predicted.
Daytime temperatures will range from the high 40s to high 50s, with nighttime temperature ranging from the high 40s earlier in the week to the low 30s closer to the weekend, based on the forecast.
