Motivated by a trip to a water park that was spoiled with hail despite a 'clear sky' forecast, he does a nice job of depicting deviations, averages, and overall accuracy in a manner that stats junkies are sure to love. From the article, 'Accuweather was the clear leader in anything greater than 10 days in advance ... many of the other less accurate weather forecasts seem[ed] to be practically worthless for all but the most optimistic.'"
