MIPs are more or less free these days.

Models might be good for long-term meso-scale trends, but no model can predict a week ahead with any semblance of reliability something as chaotic as birth and development of a storm.

Even after a tropical disturbance begins, none of the models can predict anything more than a 2 or 3 days ahead with any accuracy.

"Four" was an excellent example. It apparently had no internet connection and failed to read the predictions of what it was supposed to do.
