The chart to remember, heading into the weekend, is the 12Z GFS snow depth forecast for day-13 (Dec 3rd). Unlike the over-forecasting of snow tendency of the GFS (and ECM), snow depth forecasts are conservative and (more) reliable. On Dec. 3rd the 12Z GFS projects substantial snow cover pushing southward through the Great Plains and across New England.
