Out of all the weather sites, I still prefer the layout of the National Weather Service's forecast pages.

The private weather services don't provide much value. Most of the local current conditions data (METAR) is gov't sponsored, not to mention the satellite imagery. The government forecast algorithms are just great -- the gov't has a mandate to do this & does it well. It does make sense to go to a private provider if you have an oil rigs, agribusiness, etc. which needs tailored weather advisories.
The only place for good local weather which isn't cribbing or catching up with NWS is local meteorologists in difficult to judge regions. For example in the hill country of northern Vermont, the Eye on the Sky forecasters will call the weather valley by valley, a luxury which NWS computers won't give.
I ask because I too find myself returning to NOAA (especially their 2-day graph gasp Java applet) as a definitive (if not deeply hidden) best source for weather info, and I lament the horrific local TV station weather user experiences are foisting on people. Attention TV meteorologists: many of you have a big enough following and brand to form and monetize your own sites (TV contract-permitting).
