"A warm, moisture-packed pattern keeps the Pacific Northwest in steady mountain snow through midweek, with the biggest push focused Sunday through Tuesday. Snow levels spend a lot of time in the 3,000 to 4,000 feet range early on, so lower elevations see wetter snow or mixed precipitation at times, while mid and upper mountain terrain keeps stacking. By Tuesday night into Wednesday, snow levels trend lower and snow quality improves, followed by lighter, more showery add-ons through late week."
"Sunday through Tuesday stays active with a prolonged wet stretch that repeatedly refreshes precipitation and keeps snow levels elevated. The individual models line up well on the overall idea and timing of this stretch, but they vary on where the heaviest core sets up and how much of the precipitation falls during the warmest snow-level phases. Expect the best accumulation to favor upper mountain terrain, with snow levels frequently hovering near 3,000 to 4,000 feet before trending down late."
A warm, moisture-rich pattern will maintain steady mountain snow across the Pacific Northwest through midweek, with the most persistent precipitation Sunday through Tuesday. Snow levels spend considerable time near 3,000–4,000 feet, producing wetter snow or mixed precipitation at lower elevations while mid and upper mountain terrain accumulates the most. Snow-to-liquid ratios around 8–12:1 favor denser snow during warm phases, and exposed ridgelines, especially in the Oregon Cascades, can see notable gusts. Colder air Tuesday night into Wednesday will lower snow levels toward 2,000–2,500 feet, improving coverage and lighter snow with ratios rising to 10–14:1. Late-week offers lighter showery additions; early March trends toward fewer organized storms and more hit-or-miss systems.
