I'm bored so thought I'd throw together a quick loop of this run showing a major snowstorm during the first weekend of December. Yes it most likely will not verify and the system in model land is still two weeks away but I couldn't resist. But...this run which goes out to 360hr is very active with enough cold air to work with.
