Are they trying to copy The Weather Channel's extreme minimalism or what?!
If they were, they sure did a hell of a better job at it. The maps are much more appealing. Although I'm in the minority of people who actually does like TWC's gray maps, I just think the Accuweather maps in the promo video are better.
Also it's clear that Renderon threw in some elements of "NBC/CBS/FOX inspired" graphics sprinkled around in that promo video and the link Trevor provided, especially the Accuweather Channel bumper/LDL. The LDL itself for example reminds me of the LDL the TODAY show used to have.
The design company hired to handle AccuWeather's TV graphics, Renderon, has released a preview of the graphics.

In some elements, the graphics are a carbon copy of TWC (the orange emblem displaying weather conditions/temperature for Boston? AMHQ anyone?
), only done
much better. They seem to carry more depth than TWC does. Kudos to them and Renderon who did a great job on the designs!
