From DSM discussion regarding north / south solutions, that line about thunder is intriguing. Either way, I hope we all get in on some lucky thundersnow.
...The EC is slower with more emphasis on the southern stream of the trough, while the GFS has a more northern stream influence, ejecting the surface wave nearly 18 hours faster. These model differences result in low confidence in details, and precipitation types could change several times from snow initially, over to rain as warming continues, and then back to snow again as system exits. Some thunder is anticipated as well..
