What if the weather forecast is usually wrong?  I live in a coastal area where the weather is forecasted over a hundred miles away on the <i>mainland</i> which is typically wrong (despite local instruments).<p>Would be cool if the app allowed you to adjust for your own sense of what the weather will be.  For example the forecast today was for snow, but out here on the water all we got is rain which is typical.  Would be nice to be able to skew forecasts based on your own crazy formulas.
