A large December storm hit the mountains of the Pacific Northwest – and left snow conditions in the Yakima Basin worse off in its wake. How might this event be a harbinger of winters to come? I offer this perspective piece, published today in

The western US is in a snow drought, and storms have been making it worse
A major atmospheric river brought record precipitation to the Pacific Northwest, yet the snow and water supply still suffered. It’s a growing problem.

Process maps derived from signatures highlight strong climate controls in the West, soils/topography in the East, and a scalable path to link process understanding to ungauged basins. Big implications for large-scale hydrologic modeling & change detection.
