It’s still mostly a cover all bases operation

Yep, one of those 2-4” stat padders we’ve been lacking until last winter.

Fwiw or not ... I'm not a big fan of the MJO unless it's in constructive interference with the WPO mode...or it has a tough time propagating convection out of the marine subcontinent. It has to do that or there's no latent heat flux --> dispersion forcing to the modulate the subtropical coupling to the mid latitudes ..etc. Right now, the RMM shows the wave struggling on the 6 wave number region, probably also because it's negatively interfering with the W. Pac/La Nina. To me that's like a "predictive firewall" ... we'll see what happens if that wave collapse tendency is real. If it is not, then the way may indeed escape the W. Pac gauntlet later in 7 ... The 7 composite is actually a cool anomaly from the NP-GL-NE regions... and then it would be in positive interference in the Americas in 8-1-2. So it's like a yes-no-yin-yang- neg-pos along this wave's progression. I figure the WPO/EPO signal is precedent (there first) ...it's liable to get damp some. The question is ... does it punch through. I'm aware the RMM has it going nuts in some of the guidance types way out there in late 7. The MJO is not a pattern forcer... it's a pattern modulator. And the latter depends on the whether neg or pos interference. It needs to be positive

Huh. So I guess they’re actually not showing “extreme cold” like I just read on twitter. Man oh man, you have to be really careful who you follow there

Is there any meteorological reason for this as opposed to the typical warming trend? Is the pattern different or upper levels atypical to the past?

High of 45.3°, lowest high of the season so far.

Today was better. A predicted high of 56 with a high of 55. The forecaster at Sterling needs to understand that with an approaching system, a warmfront in southwest Va. with CAD creates low values over N.W. Va.

What’s even wilder is there are some places in eastern N.C. that still haven’t hit freezing, and Florida got this cold

Lamar has an ankle injury now. After knee and hamstring. Dude is far from 100% clearly. Almost just say to rest this week against the Jets and let Snoop play and be ready for Thanksgiving.

Didn't places in the Dakotas go from 70's to feet of snow in 12 hours Sent from my SM-G970U1 using Tapatalk

Winter arriving in mid-December. As predictable as tides.

Pattern looks to be shaping up for the coming weeks for below average temps. The risk for winter weather should increase. Just like the Pirates signing a notable free agent Ill believe it when it happens.

You don't see this that often so things can, and have, been worse.

As @WxUSAF said, we seem to be consistently trending cooler as we close on events.

Good for you. Get conditioned for heavy heavy hips n lips shoveling.

Sadly, the trend today in models has been to dry it out for most of the area, with the precip focused further east. We'll get a little rain it appears, which is better than nothing, but still disappointing given the potential.

We are so back!

Interesting look.... FWIW. Something to maybe watch 10 days out...

What is even wilder, a lot of higher elevation folks are already on the board. I am even on the board w/ 0.5" of snow already, and w/ a NW flow event to boot!

The mean doesn't have dump into Texas. In fact, it might have the trough too far to the East. Right now(and I know you know this...but this is for new folks), it is so tough to know the trough axis at this range - IDK at this point. Some modeling is just sending the cold straight to Texas. Some tends to send into the SE or NE and the MA. I would suggest the MJO is driving that along w/ the SSW. If that MJO stalls, we all will probably be just wanting it to warm-up. In my mind, I see a cold shot after Thanksgiving, a warm-up, another cold shot around the 3rd which means business....and the cold keeps on coming until about Christmas when the pattern moderates. The danger is that some modeling does not want to moderate after Christmas. There is a small camp of model runs which deepens the cold to enter January. In fact, seasonal cold is the warmest those runs get w/ well BN being the base pattern. Now, I hate even to mention that on a forum. If it doesn't happen, the disappointment is tough for some....and that hasn't happened since maybe 09-10 But it is worth noting. Those runs aren't quite outliers either. The MJO above would support some of those runs. The interesting thing is if the MJO were to loop back into the cold phases w/ no tour through the warm phases...we haven't seen that type of plot recently. Plus, there is the rare tour-de-warm MJO that never gets warm. This is IMHO is class -QBO territory in terms of analogs.

The Chinook is absolutely correct. The write up is as follows: "A downslope chinook wind event pushed the temperature at the town of Loma from -54°F at 9 am on January 14, 1972, to 49°F by 8 am on January 15th. The 103°F (57.2°C) rise is the greatest change in temperature ever officially measured on earth within a 24-hour period." Can you imagine? According to AI , the Lancaster daily range record is 57 degrees set on December 23, 2022.

Precip is AN on the mean and all over the place on the control. The control implies good precip for western areas of the forum(remember the boundary) and then again for coastal areas from Georgia to the MA late in December. E TN and W NC would be BN for precip if the control is correct. If the mean is correct, the entire forum is BN w/ temps and AN for precip. I think the cold is under modeled at this point - I didn't think that a few days ago and my mind can change on that again. If it is, the storm track is along the spine of the Apps.

I always hated to see a Trough dig deep into the SW. Without blocking that generally pumps the SER. With blocking you can get overunning or Waves eject Eastward that pay dividend's. However, with a -EPO you can sometimes get cold highs drop down east of that SW trough and get cold but, usually dry. The above Depictions Carver posted are showing good progression. Somewhat of a SER can be good for our Area as Carvers noted. Waves ride along that Boundary. Just my Antique 2 Cents worth.
