Dr. Amy Butler had a good thread on Twitter yesterday about late SSWs and the MJO phase when they occur. Long story short, this current setup and SSW is conducive to producing a durable -NAO in a couple/few weeks.
After this mess, seems like we get a PD weekend cold shot, but looks very transient so would need a well timed storm hot on its heels to take advantage.
This thing cutting off so far south isn’t going to do us any favors. We need it to cutoff farther north so there’s still some meager amount of cold air aloft when it gets here.
