Whenever I post a snow map of the NAM or another model in the winter, it doesn’t necessarily mean that I believe what it is showing.
The models that I post, which are NOT ALL snow maps, are merely a depiction of what a particular model run is showing. No model run should be taken as gospel truth.
I like to show the model output to get all of the possibilities on the table. Then, we can evaluate based on storm track, telleconnections, trends, and several other factors.
Also, so many posters comment on model runs, but do not post maps. They just say “it’s a good or bad run” or it went “north or south”, with ZERO context or quality content.
A good run for my yard might not be good for yours, so I take the time to post maps so people can see how things stand for their location.
