Significant Snow Storm Possible Across Northern New England, and Northern New York

Local Update...
   First Significant Snowstorm Of The Season Possible Midweek...

     Its been a while since I have posted but I am back with an update, I am hoping to get more frequent updates out now that the winter season is approaching.

     Things may be shaping up for out first significant snowstorm, including the larger valleys. Weather models have been indicating that a digging jet stream across the eastern US will bring a significant amount of cold air, even down to the deep south. Weather models are not exactly in very good agreement, but the most consistent has been the ECMWF. This model thus far has performed very well. The GFS model is showing a much weaker low pressure system forming well out over the ocean and not effecting the area much at all. The NAM model is now coming in on the storm system, and the 12z run of the NAM indicates that the low pressure system would explode with a minimum central pressure of 976mb being a potential blizzard. Now I want to make it clear that I highly doubt the 12z NAM run will come true, I think its still having some difficulty handling the storm. What is interesting is all models indicate that the digging jet will cause things to go negative til which would allow the Low Pressure system to form out east of cape cod and track back to the Northwest, and up over eastern New England. This will bring significant moisture into the Northeast.
     So what I feel will likely occur is that we will receive a storm, a low pressure system will form southeast of the Gulf of Maine and track to the Northwest. Across Maine, this will bring plenty of moisture into the region. Now I don't feel it will intensify to a 976mb bomb of a storm but, I do feel it will be around 990mb when it affects us. I feel the storm will be mainly snow in the higher elevations, and a rain snow mix changing to all snow in the Valleys. Now its way to early to call any snow accumulations but the potential exists for 1-3 inches in the valleys, and 4-8 inches in the higher elevations. This snow will likely be very wet and heavy. I do want to urge that we could end up with more snow if the NAM were to actually materialize, and significantly less if the GFS materializes. So right now, we will play it conservative. Stay tuned for further updates.
