In all honesty, I find the broadcaster's versions of the forecast to be complete crap. Spence is pretty knowledgeable though, and usually isn't too bad. That Tod Gallant character....well...no comment. For the closest 1-5 day, EC is about as good as it gets.
If you look at my site on the forecast page, you'll notice the forecast of a program I'm using. It's a VERY detailed program with a pretty steep learning curve. I havn't really got my head around it much yet, but just playing with it on auto mode, it spits up some pretty close forecasts. At least as well as Toddsy Gallant can do!
