JB apparently continues to draw comparisions to the way the pattern evolved at this time in November 1950 and November 1974. Only thing is, both Novembers were a lot cooler than this one has been so far.

November 1950 saw an incredible snowstorm around the 25th, while early December 1974 saw a big storm for places in Michigan, but nothing much for Toronto or Ottawa. He thinks a big trough will develop in the east around American Thanksgiving week.

Every very warm month seems to be just a bit warmer than those very warm ones years before. For some this month is likely to break the record from November 2001.

GFS ensembles are trying to retrograde the AK death star back towards Siberia. It's still a rather crappy pattern, but the -NAO does try to assert itself. I think Ryan and/or Phil mentioned it...but we also have to flush the Pacific taint out of Canada if we want some sustained cold. The will take an EPO phase change. However the cold might be satisfactory at times for the interior anyways.

It still gonna take at least the 1st week of December and likely at least through mid month to rid this type of pattern. Remember though, that "pattern" is an average term to describe the period within question. Of course we may be able to sneak something in when the pattern temporarily cooperates. It's slowly trying to get better, but patience my friends.

Yeah GFS ensembles show hope by day 15. Unfortunately I think they're probably too fast in breaking things down and once we flip the EPO it will take time to replenish the cold in NOAM.

So we'll get there... I think everyone is happy we're dealing with this now and not later in the season. I think we'll probably see December average above normal.

The GFS as a very strong burst of lift tomorrow aftn. It looks unusually strong, but would surprise many I think....IF it happened. The euro also has a good burst of lift in the mid levels from 18z through 00z. Yesterday it looked like it would be a little further west, but it slid east slightly. Actually, the Euro came towards the GFS a bit.

Cool. Just looking at them now. Don't they use some of the 12z data though?

bob, to be honest, i'm not sure how exactly they work with respect to data initialization. i know they are considered to be 3 hours OLDER. i'm sure someone on here knows.

supposedly though, they will eventually be run on the same schedule as everything else which should make them better because as it currently works they don't incorporate the 00z and 12z upper air soundings .
