Strange... I haven't noticed any problems with my area's Intellistar today. I just checked the local forecast right now, and everything's as it should be.
Some are back up now. Did you notice anything between noon and 3?
I didn't. Granted, I didn't watch for those three hours straight, but if I'm going to "randomly" turn on The Weather Channel, it's going to be as close to the local forecasts as I can get.
