SnowBrains Forecast: 18 Inches for the PNW This Weekend - SnowBrains
"An active Pacific Northwest pattern continues through Monday night, with snow levels starting high and then steadily dropping to improve snow quality late in the weekend. The biggest accumulations stack up at Whistler and on Mt Hood, while the Washington Cascades see a wetter start that transitions to more consistently snowy conditions as snow levels fall. Expect the densest snow early (especially near the passes), with SLRs generally improving into the 10-14:1 range by late Sunday into Monday for better, more skiable powder."
"The main event runs Friday night through Monday night, bringing widespread snowfall with the best outcomes where snow levels crash late and lift the snow quality with them. Snow levels are elevated early in the storm (roughly 4,000-5,900 feet depending on location), so the first half skews wetter and denser at lower elevations, with SLRs commonly in the 7-10:1 range. By Sunday night into Monday, snow levels drop sharply (down near 1,200-1,300 feet at Whistler and closer to 2,300-3,900 feet across much of the Cascades),"
An active Pacific Northwest pattern persists through Monday night, with snow levels starting high then steadily falling to improve snow quality late in the weekend. Whistler and Mt Hood receive the largest accumulations, while the Washington Cascades begin wetter before transitioning to steadier snow as snow levels drop. Early snowfall is dense, especially near mountain passes, with snow-liquid ratios (SLRs) near 6–7:1 to 7–10:1 before improving. By late Sunday into Monday SLRs generally rise into the 10–14:1 range for lighter, more skiable powder. Strong gusts threaten lift operations at Central Oregon and Mt Hood volcano resorts during the main storm.
