First of all, NO SCAND blocking, NO PV in Eastern Canada, for starters if you wanna compare actual dates 12/27/92 and currently. And to kick it off, the US is in zonal flow in 1992, while currently, 2003 ridge Eastern/Central, trough West.
Dec 27th, 1992 500mb Heights.

Dec 27th, 2003 500mb Heights.

Also, the QBO and SOI values are vastly different. The QBO values are as different as night and day on Dec 27th, 1992 and 2003. In 1992, the QBO was already WEST, meanstwhile, the QBO remains WAY NEG (EAST) now.

SST's - somewhat similar -


Again, I do NOT know why 92-93 is even considered ...
