CMC Ens 5-day mean for Dec 22-27. Run 2 days ago vs. today's run

The looks coming up is almost a blockier version of jan-Feb 2014, but the cutoff subtropical strength ridge over the Arctic is what separates this one coming View attachment 126334View attachment 126335View attachment 126336View attachment 126337

That looks really good. I might be wrong on this, but for SE snowstorms, I seem to remember an old post that Allan made one time that showed that it is ideal to have the negative anomaly center over TN. Regardless, the image above looks quite chilly!

Brutal. It's nice to see better placement and deeper cold as we work in. Still have to get down the home stretch, but we are usually trending in the opposite direction.

As an aside, I know it's not possible, but I wish all of these vendors who like to use the same color scale would also use the same numerical scale. Like, green for provider A is -.001F and green on provider B is -538 C.

What's the web address for those historical H5 maps?

12z euro has a little slug of precipitation with the Saturday system. 850’s at the time suggest it would be a close call on precip type if anything can fall

Mhmmm

Euro is getting closer and closer to interacting the TPV-pac trough the right way, when that happens a piece of the TPV is sent towards us, a western ridge pops, and the other part gets sucked in the pacific trough, which feeds it, love to see that euro trend.

Just a beautiful block over Alaska and the -NAO is almost textbook.

I wouldn’t be surprised if there would be a little sleet mixed in if precipitation were heavier

Watching to see if we can dig the TPV and get something going here. Heights are lower further southwest so lets see where it goes..

Let’s ------- go guys. Western ridge going up each run, bye bye western dump

 

[Myfrotho704_]

---- the western trough, get that ---- outa here !

Are we looking at a Rex block next week too?

Nothing like a good ole death star sitting right above you

Slight changes this run

Causal 495 TPV over NY

This looks like it will allow shortwave amplitude into the southeast via the gulf w/o just jutting up the coast?

Can’t draw it up better than this. Beautiful position of the +PNA blowing up out west.. piece of additional energy following behind our arctic airmass dump and TPV.. oh and there’s nowhere for these pieces to go under that western based -NAO … yeah that could work.

Neat bonus feature: a ridiculously anomalous -EPO
