Still watching the latest model runs rolling in, however light snow is only an hour or two away, and it's time to watch radar, satellite, and the trend of current temperatures.
The GFS and NAM still fail to agree on the final result of the storm. The 00z and 06z GFS shifted toward the NAM's lower QPF with under an inch for all of SNE into CNE. Regardless, it's still advertising some very good omega of better than -20ub/s centered around 6 to 7pm. This is the timeframe that heavy snowfall rates of 1 to 2 inches could occur.
Meanwhile, the 12z NAM is rolling in. After displaying mediocre QPF for the last few days, suddenly, less than 12 hours before the height of the storm, it doubled QPF and is now in fact more robust than the GFS. It will be interesting to see what the 12z GFS comes in with. Otherwise, not much has changed with respect to the fact that CNE and NNE needs to prepare for a significant to major snow storm this evening.
For Keene -
Given continued model discrepencies, I'll hold at 6" to 9". More specifically, I expect 6" to 8" for lower elevations and 7" to 10" above 1000ft.
