This was posted by Boston NWS at around 4 today. It’s just one data point, but they don’t seem to be buying into bigger numbers. Maybe they’re seeing a sharp cutoff near N Middlesex County - about 35 miles from the coast!
From their 7-day forecast page. This morning it had about 15” now down to 4-8” and snow not starting until after 11am on Saturday and ending around 9pm.
