In all of my years monitoring weather, Accuweather has been one of the best sites for accurate forecasts. They are occasionally wrong on what time it will rain, and rarely wrong on whether it will rain or not at all. They are right enough that I check them first before other sites. Their radar is especially up-to-date. If you are out and about and want to know if it will rain, use your smart phone to check accuweather’s RADAR and see for your self if the storms are coming!
Other good weather radar sites (Intellicast and Weather Underground):
