The Europeans are putting big money into weather forecasting, "The goal is to be able to provide, by 2025, reliable forecasts up to two weeks in advance."
Judging by last week's forecasts for my region: pretty far off. Sudden rain in the regions of 10mm/m² and a lot of clouds when sunny weather was predicted. The exact opposite happened as well. Temperatures were off by 5-8°C, too.
All of this for same day forecasts, not even 2 days in advance.
rain is pretty hard to predict though. I guess what matters the most is if you can reliably predict major events like heavy storms rather than if you will get a bit wet later today.

As far as I know other than this model upgrade, there are no major investment being made in American weather forecasting.
