There is a high ceiling for how much snow the storm could generate, but it could also just produce a glancing blow or even head out to sea with little impact.

Moisture feeding from the south will bring first snow and then a changeover to freezing rain and all rain across New England. This slow-moving storm could result in sizable snow, ice and rainfall totals, making it potentially the most impactful storm so far this winter.

S​now and ice will impact millions across the nation's northern tier this weekend as the latest in a string of winter storms tracks across the country. The system has been named Winter Storm Jett by The Weather Channel.
