Here is the other problem. Note the massive anomalies near Davis Straits. You'd think big block right? But look at the curvature of the height lines. Some subtle anticyclonic turning, but for those anomalies...you would expect more of a stout, deep ridge there....even in a smoothed out mean. I think the puke Pacific look is just pumping warm air into the normally cold parts of that area in Canada. The result are heights that are probably biased high due to warm temp anomalies vs actually a giant ridge. The temp anomalies are near +20F. I don't doubt there are members with a ridge in the Davis Straits, but perhaps don't be fooled by those massive anomalies, as that may be more of a result of Pacific puke air.
