Weโre kicking off the Christmas week with multiple waves of snowfall across the Sierra, delivering deep turns just in time for the holiday. Upper snow levels this weekend will give way to colder air by Tuesday, setting the stage for moderate to heavy snowfall in many resorts. Another system will roll in Thursday into Friday night, promising a second shot of powder before the new year.
An unsettled pattern remains over the Sierra through much of the week. Snow levels will initially hover around 8000 feet or higher, meaning only the upper mountain terrain will see fresh snow from the first round on Sunday. Winds along the ridges will be moderate, potentially strong at times, so keep that in mind if youโre planning on venturing off-piste.
As we move into Christmas Eve, a colder system sweeps in, lowering snow levels. By late Monday night into Tuesday, expect snow levels to dip closer to 6500โ7000 feet, bringing more widespread coverage across the resorts. This storm also carries enough moisture to deliver moderate to locally heavy accumulations, so holiday powder turns look likely for Christmas Eve and Christmas Day.
The next wave arrives Thursday, lasting through Friday night, bringing another round of fresh snow fairly comparable to the Monday night/Tuesday storm. Winds will remain breezy at upper elevations, so be prepared for variable conditions on the ridgelines and potential lift wind holds at higher elevations.
Temperatures will generally stay cool enough for decent snow above mid-mountain levels, though mid-mountain elevations and below could suffer from variable temperatures and mixed precipitation types. Between each storm cycle, there may be brief lulls, but overall, a steady flow of winter weather should keep conditions fun and fluffy up high. Itโs shaping up to be a white Christmas indeed for much of the California high country!
