Algorithmic forecasting.
If you squint really hard, the entirety of computer science falls under "AI". But practically speaking, today AI refers to ML.
It's quite possible a savvy programmer integrated the weather forecast to the ERP, with specific products tagged as relevant to a sunny (or wet) outlook. That's not AI, that's just an algo.
It's also possible there was ML at play, but that's not clear, and not necessarily the case.
