MJO stuff...First off, that is not a warm look for December. In fact, it kind of just crawls through the left side of the plot which is not something we have seen in recent years. It seems like the MJO almost defaulted to 4, 5, and 6. How many times have we seen the MJO hit the wall in phase 6 and not move? It looks like this time it might hit the wall while in the cold phases for once. That "could" mean an extended period of cold. If you like really LR thinking, I have to wonder if it can get through the warm phases(before winter fades) if it exits the cold phases in late December or early January. I think it can...and probably by the last third of January. That would give us two decent shots of cold if one assumes winter comes back during that last week of January. But that second cold shot can be difficult, but the QBO may help us in that regard.

Felt like winter late last night and early this morning as I had to bring my wife’s car in for service before a long trip. One cold November I recall about 25 years ago had a light coating of ice on the Charles River a few days before Thanksgiving. I’m pretty confident of our best start in a long time. We may have some driving issues the first week of December along the heart of the LES country. But I’m bringing my boots, ice spikes which may be needed, and heaviest coats, gloves, etc. It’s coming!

This was one of those easy snow day events that we need in January and February.

This feels like Groundhogs Day.

Actually, I don't know why it posted that way. It was supposed to read "can you guess where I wish I was?"

Stay safe

The wave amplified much further west this run, so the low formed farther west and the cold didn't get a chance to dig as south as the earlier run either. Like I said, there is a trough in the east and some energy around, maybe something can happen.

Finagled 22 here on the river. 18 just up the road.

The idea of an imminent SSW/MSW event is a high-confidence one. However, there is often a tendency to treat forecast developments (“SSW → PV split → EPO-/WPO-/AO-/PNA- → brutal NE weather”) as if it were an inevitable, linear, cause-and-effect chain. If such logic were reliable, forecasting accuracy at multi-week stages would be high. That isn't the case. I personally believe that there will be an increase in wintry effects, especially from near mid-December into at least late December based on typical 1-3 week lags and the currently forecast teleconnection evolution. That's my baseline thinking at present. However, that thinking isn't cast in stone. Reality is messier. For example, not every SSW leads to a prolonged deep AO-. Not every AO- period results in severe cold and/or excessive snowfall. From this far out, model skill is poor to non-existent on critical synoptic factors e.g., future storm tracks, the emergence of North Pacific jet streaks, exact ridge-trough placement, etc. A bad pattern coupled with a well-timed phase can produce a big snowstorm; a great pattern but badly-timed phases or absence of shortwaves can result in a lack of snowfall. Seemingly favorable ensemble means can also disguise large differences among ensemble members. Clusters can provide insight into some scenarios. Here are the forecast 500 mb anomalies at 360 hours: Here are the latest 500 mb and 1000 mb ECMWF clusters: 500 mb: 1000 mb: For now, potential is on the table. But nothing is locked in, just yet, in terms of specific details.

12z GFS for the people who were confused at my post earlier lol:

Natural gas is up 4.5% on colder model trends.

Dryslot: Pretty chilly this morning, 17F, Not fake. Only got down to 20 here - wind must've lasted a few hours longer. Not many autumns where you got below 20 before this rad pit. Even Tip got into the teens first.

Hi

And imho it's not the speed of the pac jet, it's the placement of the strongest portion of the jet and it's exit region. If the jet is favored equatorward and its exit region is just south of the aleutians, we get ridging over AK and cold air flowing south into the CONUS towards the east.

That low for 12/5 needs to be in the Florida Keys at this point for me to take it serious at this range on the GFS.

Been using fake effect for a while now.

Works for temps and snow

0.07 here.

That last week of December looks mint. Unfortunately it's 5 weeks away Until then, looks seasonable for us (upper 30s mid 40s on average)

Off topic but tornado lovers might get a kick out of this website I found off Reddit: https://www.tornadopath.com/tornado-history-near-me

07-08 is the nearest to a W2W winter I've experienced south of Fort Kent, and even that one had a very mild week in January, as 7-13 averaged 17° AN and the 8th was +26, greatest AN day we've had in Jan. Fortunately, that thaw had no accompanying deluge.
