Long Range Outlook: Jab, Jab, Boom?

Updated 11.10.22 @ 9:18a

After a warm open to November, things are progressing to plan as our much anticipated mid month shift to cold takes place.

A quick glance at the teleconnections over the course of the next couple weeks (remember, we still lean heaviest on the PNA and EPO at this time of the year) reveals agreement in the short term of the cold shift but note movement back towards neutral towards the end of the period.

While this may give reason for panic to some, we note the MJO scheduled to move out of Phase 8 (currently), whip across the “null” phase before moving into textbook phases for eastern cold for late November (Phases 5-6).

The analogs for such phases this time of year will make winter weather fans salivate.

Despite this setup laid out above, the new JMA Weeklies want none of my idea of a cold start to December. Despite the chilly look Weeks 1-2, the model rolls right into an eastern ridge by early December. It’s safe to say as of now, I remain in the cold camp, especially given what the MJO amplitude should provide as we rumble into the last month of the year. Nonetheless, it’s less than ideal to see a normally trusted model in such disagreement and we’ll have to keep an eye on trends over the course of the next couple weeks…


Perhaps the model is seeing a transitional move through Phase 7? That would allow a milder pattern in briefly, but again I would reiterate the look of what should be an amplified MJO as we move into December and a jaunt through Phase 8, 1, and 2 is likely in my opinion. Just for fun, this is what those phases provide.

One way or another, we have a lot of work (and fun) ahead. My hunch tells me any long range (what would currently be Week 4 in particular) data will be forced to cool, and perhaps significantly so, as time draws closer.

In the meantime, don’t sleep on next week. There should be at least one attempt for some sort of winter weather maker into the Ohio Valley, if not two.

The Expected November Transition…

Updated 10.25.22 @ 5:08p

(A friendly reminder that our annual Winter Outlook will be posted Friday morning).

When we look at our top 2 analog years (’75-’76 and ’00-’01), we note a couple of common themes in November: cooler than normal anomalies were favored across the West while the East was favored warmer than normal. Note the temperature scale differences at the key on the bottom of both images.

Another common theme in these Novembers? Cold started bleeding east mid and late month, which eventually set up cold, wintry Decembers and a fast start to winter across the Mid West, Great Lakes, and East.

The new European Weeklies hold the ridge east through the 1st half of November. Given the EPO, PNA, and MJO (not to mention analogs above), there’s no reason to disagree with this. In fact, early November will likely still include some 70° days, if not flirt with 75°+.

November: Week 1
November: Week 2

Notice what transpires as we rumble into late November and early December: A totally different look at 500mb as a trough begins to form in the exact same place the persistent ridge will reside to open the month. Winter enthusiasts have to also love the look of high latitude blocking.


Wholesale pattern “transitions” can be finicking and will require close attention as we get to mid month and closer to Thanksgiving. From this distance, there’s no reason not to think our longstanding idea of a mid month colder shift has merit. Then, it’ll be time to understand how the vastly different sea surface temperature anomalies (SSTs) may impact the December and quick start to winter idea.

More on this and the winter as a whole Friday morning!
