SnowBrains Forecast: 2 Feet of Additional Snowfall for the Rockies, Tetons This Week - SnowBrains

"A busy January 5-9 stretch brings frequent light-to-moderate refreshers across the Northern Rockies, with the deepest totals focused on Idaho and the Tetons while snow quality trends better and better as the week turns colder. Snow levels start relatively higher in parts of Idaho early in the window, then steadily crash through midweek, flipping more of the precipitation to snow and boosting snow-to-liquid ratios into the 14-20:1 range for a noticeably drier, fluffier feel late Wednesday into Thursday;"

"Monday-Tuesday sets the stage with on-and-off snowfall and gradually lowering snow levels, with the most meaningful early punches aimed at central and northern Idaho plus the Tetons. In Idaho, snow levels hover around roughly 4,500-5,000 feet early Monday into Tuesday, so lower elevations can skew denser at times with SLRs commonly near 10-12:1 (a thicker, more moisture-laden snow), while mid and upper mountain terrain does far better."

"Tuesday night-Wednesday is the main reload window for most areas, then Wednesday night-Thursday turns colder and improves snow quality even where snowfall rates ease. The Idaho resorts are the headline act: Brundage leads the region with a sustained storm total of 17″-23″, with Schweitzer close behind at 12″-18″ and Tamarack at 12″-17″ as snow levels fall sharply and SLRs rise into the mid-teens and upper-teens late in the event."

Frequent light-to-moderate snowfall will affect the Northern Rockies January 5–9, with the deepest totals focused on Idaho and the Tetons. Snow levels start relatively high in parts of Idaho early in the period, producing denser snow with SLRs near 10–12:1 at lower elevations, while mid and upper terrain performs better. Tuesday night–Wednesday brings the main reload, then cold air late Wednesday into Thursday lowers snow levels and increases SLRs into roughly 14–20:1, yielding drier, fluffier snow. Brundage, Schweitzer, and Tamarack are expected to build the largest accumulations in Idaho, and Grand Targhee and Jackson Hole remain productive. By Friday snowfall becomes spottier and lighter, and the weekend trends quieter with a warmer, drier bias.
