BullShark,
Wunderground gets SOME of their data from NOAA, just like everyone else. All I know is I could look at NOAA, Weather Channel, local forecasters, and any other place I felt like...and would get ten diffrerent answers. Then I'd look at Wunderground...and the graph would show the winds at 15mph until noon, when they were supposed to die down to 5mph. I'd go out at 11:30, and at noon (or whenever they said) the winds would die down. Try finding that from NOAA...Weather Underground may look like just another web site....but look deeper (and test it!) and I bet you'll change your mind. I'm a storm spotter here in Texas, so I'm pretty well versed in weather data...I have an actual NOAA log in like you local weatherman has...but I still use Wunderground.
