Remember the classic movie "Airplane" where a passenger offers to translate a conversation with an urban resident?
Yeah, the NWS does love to speak jive. Hard to catch their mistakes that way, I guess. Who's gonna question somebody who knows the words "secondary cyclogenesis"? Kind of like walking out of the doctor's office wondering whether to buy aspirin or a cemetery lot.
Anyway, I read this as they believe that a blast of cold air will come in tomorrow night and meet the warm, wet, air arriving after midnight. There should be snow over most of New Hampshire, but an on-shore wind along the coast will cause a turnover to rain there. The dividing line is still unknown, but right now they think it's near Concord. There's about a ½" of water available, so depending on where you are you could get anything from a ½" of rain to 6"+ of snow, with the mountains more likely to get all snow.
BTW: Secondary cyclogenesis occurs when a low pressure system causes tornado-like winds that grow explosively. I guess they're saying it could get pretty windy in places, and are looking at small craft advisories for Friday.

Does that include snowmobiles?
