Decided to quickly update my map to reflect likely sharper gradients and lower totals to the SE.
There is still some uncertainty about a dry slot. If a dry slot takes place, it would be most likely south and east of a Boston to Providence line, but one could occur elsewhere as well.
The mix line could waffle northwest and southeast a little bit, and thus could dramatically affect snowfall amounts for those outside of the 18-24″ zone. Those in the 18-24″ zone should be safe, along with most in the 12-18″, but beyond there, snowfall is uncertain due to that factor.
Have a good night!
