We identify where Western US snow projections agree and the proportion of snow that falls within regions where end-of-century projections of snow disagree as a result of disparate snow modeling approaches. Results show that a majority of the area of the Rocky Mountain and Cascade Mountain ranges have projected changes to snow that are in relative agreement, but have divergence in annual snow water supply estimates in higher elevations. These results highlight where further research may most improve our understanding of future snow water supplies and the associated downstream water resources.
