I find their error model to be off for my location. I'm in a mountain valley in Colorado, and forecasting the weather is like throwing darts at the wall (especially with precipitation).

We have no radar coverage, and the only "official" sensor I know of is at our local airport. It was recently upgraded to be somewhat accurate, but isn't operational about half the time. The most accurate forecast we have is the text synopsis from a forecaster in Pueblo talking about how it "might be stormy in the afternoons this week."

Our nearest city is a 2.5 hr drive, so we're in a pretty big gap of weather coverage!

Anyway - hope someone finds this interesting. I envy those of you with accurate weather! It has been interesting moving out here.
