Ostrich December

Like this look better imo, -EPO can tap into some of the coldest air vs what we’re about to experience which is mainly Canadian air
Gotta watch out for any SER signal given sometimes that can happen with a -EPO but it looks alright right now

This is a much better look and shows a little bit of what I'm talking about with Canada. One thing that tends to happen that we need to watch out for is that the ridge rolls over allowing for a SW troughing, which pumps heights in the SE. You see the SW trough signal showing up here, but it may be an artifact of a strong STJ, as you still see lower heights across the SE. It could end up being a good pattern for a bit, if it sets up that way and if eastern Canada starts to get cold.

Of course, our -NAO remains in hibernation.

Are we going to go in a cycle we’re the ser comeback for a few weeks and then +pna makes a comeback to the eastern us cold again

It’s too far out to get a really good read on this but I’d argue the SER comeback beginning after mid month will probably last longer than a few weeks
 
The transition between this big +PNA and retrograding -EPO becoming -WPO late month will feature giant shots of true arctic air instead of more moderate continental polar air masses. We should still have a favorable pattern for wintry weather thru mid month will much more cold air anomaly wise and an extra 2-3F of cooler climo certainly will help too, the question will start becoming how much juice is left in the subtropical jet beyond next week
 
Interestingly enough, even though the EPS wants to go towards a poorly tilted -EPO, it also wants to push a -NAO. I usually would say blasphemy, but we are actually going to get a -NAO during the first week of December, notice no SER. Any implications as to if this is a likely evolution?

I think Eric said that if we got the -NAO then it would crush the southeast ridge for a little while longer.
