Tuesday, March 10, 2026 with Tyson…
Northwest Flow in the Wasatch gets locals giddy. It refers to a phenomenon where storms begin on a warm Southwest flow, then finish with colder temperatures on a NW flow. The moisture tracks SE across the Salt Lake Valley, sometimes augmented by lake effect, before
funneling up the canyons. Orographics mean the clouds dump their load on the windward side of the range, i.e. lower Big and most of Little Cottonwood often get heaps of light-density fluff.
Last Friday, 3/6, UMA guide Billy Haas aptly described trail-breaking in 3’ of fresh: “trench warfare.” The second piece of this storm system was forecast to be colder than the damp, dense Tuesday part. Thursday morning it had only snowed 3”, and the “splitting” storm was mostly missing the Salt Lake mountains. But…there was NW flow!?
When any part of the jet stream is south of us, we tend to get windless fluff, often more than expected. Huge stellar-conglomerate flakes added up to 20 inches at Snowbird, and I was glad to be there, ski-compacting steep runs all over the mountain with no lift-lines. By Friday up to 36” had fallen, with only 1.85” of snow water equivalent (SWE). Woo hoo! It bonded well to a damp, dense underlying snow, and light winds minimized slab formation.
Savvy tourers loved classic backcountry lines immediately after the storm, and before March
temperatures soared. Good things come to those who wait… In the meager winter of 2026, the greatest snow on earth finally blessed the Utah faithful!
