As a local, I don't use either Accuweather or weatherchannel.com - I don't find them to be accurate enough. I use the local affiliates WFTV and WOFL most of the time. WFTV only does a five day forecast, and WOFL does a seven, but even so, they are really only accurate out maybe two or three days most of the time. Both of them do forecasts every ten minutes on weekday mornings, so it's easy to get a quick forecast before heading out to the parks as well.
