LAKE COUNTY, Calif. — A series of inbound winter atmospheric river storms are forecast to bring several inches of rain and — in the higher elevations — snow into early next week.

The National Weather Service’s Eureka office said rain will arrive late on Thursday, with as much as 4 inches expected to fall across Lake County over the course of several days.

The Lake County forecast anticipates daytime conditions on Thursday to include temperatures in the high 50s and mild winds from the southeast.

There will be up to a quarter of an inch of rain on Thursday night, when temperatures will dip into the high 30s, with light winds of just under 10 miles per hour.

The rain will continue on Friday, with light winds continuing and about an inch and three quarters of rain. Daytime temperatures will be in the high 40s, dropping to the low 40s at night.

Another one to two inches of rain is forecast to fall during the day on Saturday and up to three quarters of an inch on Saturday night. Temperatures will be in the low 50s during the day and the low 40s at night, with mild southwest winds.

The California Nevada River Forecast Center said the storms are expected to cause Cache Creek’s flow to double and for the level of Clear Lake to climb from just over 6 feet Rumsey — the special measure for the lake — to nearly 6.8 feet Rumsey.

The National Weather Service said another atmospheric river is expected to arrive on Sunday.

“This system has more moisture and the potential to bring at least localized flooding if rain falls on the same areas that receive the rain Thursday night through Friday night,” the National Weather Service reported.

Forecasters said it’s uncertain of where that second storm system will hit and how much rain it might bring.

That rain will combine with temperatures in the high 40s to low 50s during the day and the low 30s to low 40s at night, based on the forecast.
