A multi-day, mostly low-to-moderate impact storm cycle runs from Saturday night (01/10) through Tuesday night (01/13), with the Interior BC mountains picking up the best totals but also the trickiest snow quality as warmer air pushes in. Revelstoke stands out for overall accumulation, while Big White and RED Mountain see lighter, wind-affected refreshers that trend denser by late Sunday into Monday.
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;
