We get pacific help but the NAO and AO going positive is a quick shot at arctic air and then reload. Until we get some Atlantic help it's unlikely to happen. Even more so for those that need a SW flow. Need some blocking to retrograde the low back to near Hudson bay. Earlier runs were showing that, but there is nothing to prevent the lows from traveling right and out through the Atlantic with no blocking. We will get some colder air due to -EPO +PNA Neutral WPO but it will be quick hitting. Up/Down pattern.
