I aggregate weather forecasts for the Event Horizon Telescope Collaboration, which is the collaboration behind those black hole images you might have seen.

We want to pick the best nights during an observing window based on the weather in 12 locations around the world. These are mostly locations on the peaks of mountains, where it's hard to do a good forecast because the ground is rugged on length scales that are smaller than the grid in the numerical computation.

Forecast accuracy has improved in recent years, but I'm really looking forward to AI forecasts. They appear to fix some systematic errors that are still present in traditional forecast simulations.
