"A stormy, wind-whipped week is on tap for the Pacific Northwest, with a warm start that favors heavier, wetter snow at lower elevations before a powerful midweek cold front drops snow levels to the passes and kicks off the deepest mountain totals, followed by a warmer late-week pulse that turns snow dense again before cooler, showery snow closes out the period."
"Monday night into Tuesday starts relatively warm, with snow levels hovering high enough that lower and mid elevations in the Cascades can skew toward wetter snow or mixed precipitation while the highest terrain collects modest accumulation. Snow-to-liquid ratios during this opening phase are generally poor to fair, with many sites running in the 5-10:1 range, so early snow is dense and upside-down where temperatures flirt with the freezing mark."
A stormy, wind-whipped week will affect the Pacific Northwest with a warm start producing heavier, wetter snow at lower elevations. A powerful midweek cold front will lower snow levels to pass elevations and generate the deepest mountain totals, especially across the North Cascades. The Oregon Cascades will see more volatility in snow levels, snow quality, and strong ridge winds. Early snow-to-liquid ratios will be poor to fair (around 5-10:1), producing dense, upside-down snow where temperatures hover near freezing. Ratios improve behind the front toward 11-14:1, yielding chalky-to-fluffy snow and better quality. Frequent strong winds will create visibility and comfort challenges during peak periods.
