is +QBO good for snowfall in the western US?
Thought for 11s
Yes — a westerly (+QBO) phase is generally more favorable for snowfall in the western US than an easterly phase, especially when it supports a stronger Pacific jet and more frequent storms into the region. The signal is real but secondary to ENSO and other drivers, and sample sizes are modest.

+QBO refers to the westerly (positive) phase of the Quasi-Biennial Oscillation, the roughly 28-month reversal of tropical stratospheric winds. Forecasters and composites treat it as a modest modulator of winter patterns rather than a dominant control.Why it tends to help Western snow
Westerly QBO phases favor a stronger Pacific jet and more storm track activity into Western North America. Easterly phases more often support West Coast ridging (drier) and polar-vortex disruptions that favor troughing farther east.

Composites show the Northern Rockies and California wetter than average during westerly QBO winters, with the South and East more often drier. Northern US areas also lean cooler.

In the Pacific Northwest, the snowiest seasons at sites like Timberline (Mt. Hood) and above-median snowfall in some El Niño years clustered with westerly QBO (e.g., 30 mb winds on Jan 1). The westerly phase is described as a colder/wetter base state there; the heaviest years required it.

Combined with La Niña, westerly QBO winters have historically shown a better chance of above-average precipitation (and thus snow) across a large part of the West, though the analog set is small.
