I'm forecasting on the low end about 8-9" here in far northwest Bucks. The warm punch means business and I think most of the snow is the WAA thump, after the sleet think the change back to snow will yield very little additional accumulation.
Paul's kuchera map is a fail for the ECM as it is going with strict 10:1 ratio over SEPA euro liquid output is 1.0-1.2" I don't know what happened but it miscalculated.
Euro pops freezing rain for a time over the Lehigh Valley likely because of the precipitation hole too, while at the same time enhances the snow risk for NYC. This is the kick in the teeth run.
