Favorite Weather Sites

Just think how much the weather means to recreation. We want snow for x-c skiing, cold temps for ice skating, and of course warm sunny days for the beach.

What is your favorite weather site on the web?

www.wunderground.com (probably my all time favorite)
www.intellicast.com (this is really good for animated radar imagery)
www.weather.com (one of the original sites)

Do you have some favorites to share?
