lol, I asked AI about AI, and it said:

Hoodoo still closed this weekend with only a 19” base after picking up 2” of snow today.

That's a good theory. AI can most certainly be subject to seasonal biases. AI uses statistics, which can result in them falling for the "correlation but not causation" issue - and giving weight to the wrong factors implicitly (especially in the long range).

Wow!

Pure cope here, but... during a seasonal transition I would buy that the AI models are worse at sniffing out unusual cold (or unusual warmth) given the even lower number of examples of those extremes in their training data around that time of year. A traditional deterministic model suite is probably going to have less bias against an unusually cold and snowy pattern during the last week of Feb/first week of March, since its output is a pure deterministic calculation that doesn't have anything to do with climo. The Euro and EPS don't have a climo bias like the AIFS does.
