Heavy Sierra and Intermountain Mountain Snow Expected This Weekend
Sierra Nevada
The highest elevations of the Sierra Nevada are set for the heaviest snow of the period. Accumulating snow is most likely over the weekend, with a solid chance of at least a foot and some locations approaching two feet. Lower slopes will see mostly rain because snow levels will stay high much of the time.
Intermountain West
Higher terrain across the Intermountain West will pick up accumulating snow mainly on Saturday and Sunday. Widespread precipitation is expected from southern California through the Northern Rockies, but only the taller peaks and ridges should turn it into snow. The snow that falls is likely to be denser than average, which can add extra weight on roofs and branches.
Idaho Mountains
In the higher country of Idaho, particularly the Sawtooth range, more than six inches of snow is likely at upper elevations. Some spots could see a foot or more. Most of this snow arrives over the weekend, with only light amounts possible a day earlier in limited areas.
Utah Mountains
Utah’s Uinta Mountains are also favored for solid accumulations at the higher elevations. More than six inches is likely, and locally a foot or greater is possible. The denser snow can settle firmly and create more noticeable loading than lighter snow would.
Colorado Mountains
The San Juan Mountains of Colorado can expect a similar pattern, with higher elevations likely to receive more than six inches and locally a foot or more. Timing centers on the weekend when moisture and lift overlap best with the tallest terrain. Lower valleys should remain mostly free of accumulating snow.
Lower Elevations
Across the Southwest and Intermountain West, lower elevations will see mostly rain rather than snow. Snow levels are expected to stay quite high through much of the period, so only the upper mountain slopes and peaks will accumulate meaningful amounts. Any temporary dips in the snow level will be brief and limited.
Nationwide
Outside the western mountains, little to no accumulating snow is expected across the rest of the country through early next week. The chance of significant ice is also very low nationwide. Most areas will stay free of wintry impacts during this stretch.
Travel Impacts
Drivers and outdoor planners in the Sierra and Intermountain high country should prepare for snowy and potentially slick conditions on mountain roads this weekend. The denser snow can make for heavier accumulation on vehicles and pathways, so allowing extra time and checking local road reports will help keep travel safer and smoother.
