I mentioned this in banter earlier, but looks like we're going to ride in the SSW rodeo again:     If the GFS is correct in its depiction of the MJO RMM plots/ convection/ whatever is going on, that would line up with a warming triggered over Siberia. Another High descending, another mountain torque, another jet extension, this time with a more La Ninaish N Hemisphere state (of course with a -NAO too):     Of course that is medium to long range,
