Models have really struggled this late fall/ early Winter. Carvers gap in the Tn Valley Sub brought up something that could be right. Feedback in The Pac NW. Watch the Cycle's and check out the Runs that keep the East colder. Look at the difference in the PAC NW.
Also, Webb has some rather interesting Ideas as well. We , no doubt need to shake any semblance of a GOA Low as we all know but, it is possible to work around it until we do. Chill covered those. The MJO back in Ph 8 hopefully helps as well.
