CAPE

It's weak sauce. There are 2 areas of vorticity, neither are particularly sharp on approach, and interaction happens too late. Low forms way offshore. Some flakes flying and maybe a dusting in places is probably the upside.

Defense played pretty well minus Roquan.

The ticky tacky penalties makes NFL football so hard to watch. Just let em play for shits sake.

There is always a shallow area of HP there during the winter months. 100 percent of the time. If you are looking at h5, then I can understand your confusion.

Ravens are hard to watch. Doesn't help when the refs are literally making up penalties to call now. Lamar looks off just like he did to start the Steelers game.

18z GEFS a little more enthused for a bit of snow Sun-Mon timeframe.

You realize the HP there is a fixture every winter, right? That area is adjacent to/part of the hyper-continental climate of Siberia(and the Siberian High). It takes a specific longwave pattern to deliver the extreme cold southward into our part of the world from that region. A negative WPO/EPO in conjunction with the elongated TPV stretching southward over Hudson bay is the potential delivery mechanism in this case. With a different longwave pattern that cold HP still exists during every winter and it is largely irrelevant to our sensible weather. This is the case many more times than not.

There might be a suppression risk, but a high amplitude ridge with a slightly west biased axis is going to give the best chance (imo) of a NS wave digging further south with enough space to allow a surface low to develop in time to affect us. A low amplitude/broader ridge most likely results in shortwaves tracking further north and/or scooting off the coast with LP development occurring offshore- too late. A delicate balance when almost all the action is occurring in the NS. 12z Euro run today H5 that results in a moderate snowstorm for the MA-

Ugly AK trough right here

The Euro has been trying for several runs for around the 7th, and it gets to a pretty good outcome on the 12z run.

The western US ridge and the downstream trough orientation/axis have been discussed. The big picture as advertised on guidance is a pattern that can deliver anomalous cold. Plenty to nitpick should you choose to do so. Might end up cold and dry- that is a 'risk'. As I said in at least one post, it will probably take a significant NS shortwave to get a surface low to develop far enough south(and west) for the MA to cash in. A higher amplitude ridge with an axis further west would help to facilitate this.

It's an h5 snapshot from an ensemble mean for a specific time on a single day. The longwave pattern phase isn't stationary.

Their best play is a hail mary lol.

lol no.

Cowboys stupidly gave em one more chance..

Oh wait, 14 seconds left lol.

Cowboys were due for a win. Law of averages can be a bitch.

WTF WFT? holy shit

Talk about a mechanism for cross Polar flow lol. Then an anticyclonic wave break sends a massive h5 avocado southward. Barney cold at the surface. Euro is feeding the weenies now that it extends beyond 240.

Exactly. That's a snapshot on a mean. The op runs depict a bunch of shortwave energy embedded in the flow over the western ridge/between it and the TPV. Strong shortwaves dropping southward will modify the the longwave trough.

If this is real we better get some snow. No weenie could draw it up any better.

We getting snow before the 12th.

GEPS is also building h5 heights in the NAO domain at the end of the run.

Stronger signal on the 12z GEFS for the 8th. 12z Euro ens hinting too. 0z Euro op was real close, as I posted this morning.

Its 'there' on the GEFS and Euro ens mean too, but barely. Looks like most of the moisture gets wrung out over the western highlands, which is typical of a weak clipper. Snow in the air and maybe a whitening of the ground in the lowlands in early Dec is better than cold and dry.
