I think you have a point in the “certainty” aspect. But I disagree with the magnitude of your claim. Very frequently, we can see better setups coming in advance. If people take that as a claim that good snow events are definitely going to happen, then it’s on them, not the original poster…unless the original poster is making those claims.
Pattern talk is inherently going to be less certain than discussing a synoptic setup 4-5 days out…I think most understand that. There’s a reason that very often you’ll see the phrase “let’s get that inside of 10 days…” or some iteration of that.
We used to have a separate thread for just pattern talk a few years back that you may or may not recall, but it seems like it always eventually just got smeared into the monthly threads so we stopped doing them.
