120 Inches to Feet: How a Staggering 10-Foot Snowfall Forecast Stunned Forecasters
By Sophia Al-Mansoor
A meteorological forecast warning of 120 inches does not materialize from standard frontal systems. It requires a rare alignment of moisture flux, thermal gradients, and topographical barriers. In early 2026, meteorologists tracked a slow-moving, moisture-laden Pacific trough colliding with a dense pool of Arctic air parked across the Great Basin.
As this moisture hit steep mountain terrain, severe orographic lifting squeezed out moisture at maximum efficiency. Sub-freezing temperatures throughout the atmospheric column ensured high snow-to-liquid ratios. Instead of wet, dense sleet, the system dumped vast volumes of dry, wind-driven powder. Wind gusts reached 80 mph along high ridge lines, dropping visibility to zero and generating massive drifts that quickly surpassed the ten-foot baseline.
The National Weather Service issued blizzard alerts that kept mountain passes closed for multiple days. For transportation departments operating rotary snowplows on Interstate 80 and US Route 50, the challenge went beyond clearing roads. They had to carve sheer canyons through solid walls of white.
