Snow Expected for the Sierra, Cascades

10 Jun 2017, 11:19 am

Yes, it’s true! No need to adjust the calendar. It is, indeed, June, but the weather will look more like March over the northern Sierra Nevada range in California this weekend.

A winter weather advisory is in effect for parts of the northern Sierra Nevada range Saturday night-Sunday night. This means light to moderate snow accumulation is expected.

A winter weather advisory has been issued from the National Weather Service in Sacramento, as several inches of snow is expected to add up overnight Saturday and through the day Sunday (yes, June 11!). The forecast calls for around 4 to 8 inches of new snowfall, mainly over 5500′ elevation across the northern Sierra Nevada range, especially near Lassen Park. Lighter totals of 1-4 inches may extend as far south as Donner and Senora Passes in California.

Lighter snow amounts are also expected over the Cascades and Siskiyous of Oregon, mainly above 4500 feet elevation with about 1-4″ anticipated. Some of the highest peaks of the western mountains can expected to at least see wet snow mixed with rain.

Forecast snow and rain accumulation through Tuesday


The main impact from this off season snow event is expected to be poor travel conditions. Slick roads may cause drivers to spin out, and add travel time. Outdoor events or recreation may also be impacted by the snowfall.


As you might have expected, temperatures will be unseasonably chilly over much of the northwestern US. Expect temps to run about 10-20 degrees colder than average this weekend as a lrge dip in the jet stream sags southward. These cooler than average temperatures will last into next week for much of the western U.S.
