Out of curiosity, is there a "grade" assigned to judge the accuracy of a
storms forecast?

What I'm think, is that we all talk about the weather....hurricanes/tropical
cyclones....but is there an objective measurement of how well the
forecasters did?

Since I'm in the USA, I'm specifically thinking of the US NHCs forecasts. I
know they use many models and then make a judgment as the which they think
is the best. From that they issue their "official" forecast every 6 hours.
But how do they measure their success? Could we grade their forecasts on
Charlie as a C+ and Francis as a B?

I'm working on some ideas and wondering if this has already been done.
