This is a pre-season Snowology Storm Watch! We've had 3 runs in a row of the GFS today showing a storm with back end and high elevation snow, with the potential for lake effect (primarily off of Lake Ontario) and upsloping into possibly Friday. This is 7 full days out to the start of this system so just to be clear, modeling will change and this storm could disappear, but we like the setup.
This comes from the trough that is expected to deliver a punch of cold next week, though yesterday it was looking like just a brush for Northeast ski country, but today we can see a tug on that trough from a meandering low crossing into the South that could give it a piece of energy that trough needs to tilt negatively and spin up a coastal storm.
The cold looks to be firmly behind this system rather than feeding into it so we'll likely start out as r@!n everywhere, but in the Fall we often see the white stuff on the back ends, and with a damp environment plenty of moisture for an extended back end event.
The ECMWF doesn't see this yet, but the model seems drunk at that range and it's not generally great at seeing real storms like this at 7 days out, but the ECMWF ensembles are showing some hints of this along with even stronger support among the GFS ensemble members. Therefore we like our chances just enough to call it a "storm watch" from this distance.
If it does happen we'll cover it in more detail, but without any ski areas operating we'll focus more on the joy than the action, but there is the possibility of some low-speed quads carrying the most dedicated up and then down (we're talking uphilling).
