Tier 3 Notes:  Comments 1. Probabilistic snow experiment has been valuable - continue to expand as appropriate 2. Move toward national implementation using WPC + WFO collaborative approach - but work toward a national map - not WFO-centric maps 3. Would like to see national implementation for the 18/19 season 4. Need more information on "calibration"
