The 00Z runs of many weather models (GFS, WRF, GGEM, EC and NOGAPS) are in agreement that we will be affected by a Nor'easter on Valentine's Day. The differences between the models relate to the exact track, and thus the position of the rain/snow line along the coast (if one exists) and the amounts of snow inland. The morning discussion from the NWS in Taunton, MA implied that if the 00Z run of the GFS were to verify, we'd be measuring the snow in feet, not inches. I used a forecasting tool developed by the NWS in Buffalo (Bufkit) to look at totals, and sure enough, the 00Z GFS amounts for Bedford, MA ranged from 24 to 43 inches

, with lesser amounts (but still well over a foot), for central Mass into central NH. The 06Z run of the GFS backed off on those totals (more in the 9 to 12 inches range). It'll will be interesting to see how this develops.
