A strong atmospheric river will produce a rain-on-snow event across the Pacific Northwest, British Columbia, Idaho, Montana and Wyoming. Rain/snow lines will rise to higher elevations, increasing the proportion of rain versus snow at lower and mid elevations and concentrating snowfall at higher terrain. Forecast rain/snow line elevations include up to 8,000'+ at Crystal Mountain (WA), around 4,500' at Revelstoke (BC), and up to 9,000' at Jackson Hole and Brundage. Snow probability windows are specified for Colorado, Tahoe, Utah, Idaho, Wyoming, Montana and interior British Columbia through mid-December.
