Big westward shift and increased snow amounts from new 18Z Euro ensembles now!

These amounts are an ensemble mean at 10:1 ratios!! Increase them by 50% for a 15:1 ratio snow. The ensemble mean for Long Island went from 10 inches to 13 inches. With a 15:1 ratio you could be looking at widespread 20 inch amounts in Suffolk!

Now we need the 3km NAM on board!
