I can understand the OP's frustration...I check Weather.com and then check two of the local stations. I like mumonkan's Weatherspark suggestion, as it seems to pool several sources simultaneously. I think a lot of the frustration comes from knowing that people in cars are going to drive twice as bad in rainy conditions as they would in preferable conditions (at least they do here in SC), so the danger factor goes up a little and it makes one nervous. As many others have stated, it's better overall to simply be prepared for the weather contingency.
