We are adjusting our snow accumulation threshold to 34F (from 32F) to better capture snowfall risks around marginal temperature events.  This starts with the 14z HRRR cycle ahead and then the 12z GFS model cycle.  One exception is the low-res GFS, which uses the Cobb method.

Added North America and North America Expanded 6hr, 12hr, 24hr, 48hr, 120hr, and total snow to Maxres GFS, GFS-ENS, ECMWF, and ECMWF-EPS.
