Ensembles (10-1 SLR) will be attached for the anticipated results of a western Canadian short wave digging into the northeast USA Saturday morning. Latitude of the leading low pressure system will assist determining the axis of best snowfall which for the most part on 2/14 is near PHL.  The SREF of 15z/ 14 is closest to I80-LI. Amounts with subfreezing surface temps and accumulation on all untreated surfaces could range roughly anywhere 1/2 to 4".   A conservative approach right now fr
