A weather forecast is a many-splendored thing (or multi-dimensional, if you prefer).

- Checking its accuracy is also a multi-dimensional problem.

You would need to compare the accuracy:

- At every point in the area of the forecast

- For correct temperature

- air pressure

- windspeed

- precipitation

- cloud cover (if sunny days are important to you)

And since forecasts necessarily cover a period of time, you may need to assess the accuracy of a single forecast at multiple points in time (eg 1 day, 2 days, 4 days, 1 week, etc). You expect the accuracy to degrade as you predict further into the future.
