The answer lies in how you interpret the data.
If you believe that a weather forecast 200 miles away is infallible, and you're used to how you brain interprets that forecast at home, then you're biases will influence how the interpretation is used.
Might be better to use two or even three weather sources.
Use them at home, see how accurate they are on a long term basis (e.g. three days from now, X forecasts partly cloudy and four degrees cooler than these other two.).
Geeking out on meteorology is quite useful in riding motorcycles.
