Event narrative
Two reports in the Helena valley of 6 inches or greater new snow, including a 9 inch report 1 mile SSW of the center of Helena.
Wider weather episode
A strong temperature gradient across Central MT and vicinity combined with moisture streaming northward ahead of a more broad Pacific trough to result in some overrunning snow. The snow became locally intense around Bozeman a bit south of where the temperatures gradient was strongest, which prompted Winter Storm Warnings.
