Not to undermine their work, but didn't Microsoft not already release Aurora Forecasting (a 1.5b model, which compared to models for text is rather small - those tend to start at 3B - which makes sense because there is also a lot less data to build a model on).
Anyway, I am happy to see competitors popping up, because NWP is hard enough already.
Oh man, I'm so happy you've told us, instead of making a snarky comment. SO, so happy...
