Plume of moisture heading for central Sierra

Staff Reports

An atmospheric river is headed for California that could bring periods of heavy rain to the central Sierra and Western Nevada.

Forecasters say the plume of abundant moisture is expected to materialize, but there’s no certainty that it will hit in the right place to bring widespread rain into the region.

The plume will run along the south side of the jet stream, which if it dips further south would leave Western Nevada cut off from the moisture.

The plume, which is more common of December or January than June, is expected to arrive Sunday and last until Tuesday if it hits the right combination.

Weather Service forecasters have middling confidence that the plume will bring moisture to Western Nevada.

June has seen temperatures extremes ranging from three days of record high temperatures around Carson Valley Days to near freezing weather on Thursday.

Carson Valley saw its first 100-degree day of the season on June 8.

A frost advisory has been issued for six Northern Nevada counties in the wake of unseasonably cold weather on the last morning of spring.

The National Weather Service has issued the advisory for Humboldt, Elko, Lander, Eureka and White Pine counties.
