It's a very bizarre site, with the ads and rambling text, but I've always found that it has very good info on things like polar vortex formation/breakdown and summer heatwaves, and pretty accurate longer term (up to a few months ahead, say) forecasts. You never feel like linking any of the articles to anyone though, because it feels like a spam blog. Very strange.
