This didn't age well. Over its last 3 runs the NAM has moved the LP center from southeast of ACK, to ACK, to Boston Harbor.
The GFS is drifting east though.
The Monday storm is going to be incredibly frustrating for snow lovers north & west of 495. Low pressure center forecast to track over ACK and its rain all the way into southwestern NH. Usually doing naked twister with the coastal front with that storm track here. But it seems not in winter of 2022-2023.
So everyone doesn't start weening out over model snow forecasts, what's the standard SWFE again? For places that stay snow generally 4-5". The jackpot is 7-8".
