I really don't have much to add from yesterday except that a disclaimer might/could be needed for the typical layman about how forecasts and opinions you might see on here are not official. But then I wonder if that's even needed based off past history. It might not be right to compare to a video game, but that community that I mentioned a few nights ago, that was actually a hacks/mods community (they weren't done for the win though, it was done for the fun, yeah, weird). It was a small part of a bigger world in that game before the wi-fi for the game shut down.
Most true laymen, and not even those that are here to be snow weenies, probably don't even search out these websites at all. Most of them most likely will just mostly check weather.com, their weather forecast by clicking a button on the remote on TV, have weather apps on their phones (and I know some of y'all here do too), or see a forecast in the local news. My dad knows about my ventures into weather communities, but he mostly is a casual like this too, and he just turned to me a few minutes ago as he was getting ready to go outside and said "so, 80 possible later in the week?" And that was most likely based off of him looking at either the weather forecast he can get by clicking a button on the remote, or the local news.
