I also follow Josh Classen on twitter who I think is the best meteorologist in Edmonton.
I am by no means an expert though, so if you guys have better resources you use to follow the weather, keep using them!
I also use the weatheroffice.gc.ca site as my main source of info. Find it to be the most accurate. You mentioned Weathereye. That is what I use on my PC as the desktop weather app, and it is put out by The Weather Network, which is actually the same outfit that puts out the App that is pictured above in my forecast pic. I switched from the weather.com app that came with the phone, as I didn't find the local weather predictions very accurate.
Where I work there are still several people who don't plug their car in. When I tell them to plug in they tell me they don't have too, their car is new or they tell me it always starts no matter how cold.
I am jealous as all Hell about the weather in Edmonton. Here in the states we've had record rain fall. I love snow... love cold. Just another part of Edmonton that makes it such an awesome city this time of year.
