  1. 06 z euro looks good to me. 12+ just about all of LI. Heavy band starting to really come together now. Should be a fun several hours coming up. This thing was a cutter without the blocking. Be happy
  2. Light snow started in Riverhead at 10 pm. Feeling pretty good for at least a foot in this area.
  3. Haven't seen it mentioned much lately, but I think a lot of the blame for that this year falls on the SSW. I remember discussion about how it would be very problematic if the cold dump was on the other side of the pole. Well, it was. Which doesn't leave much to tap into on this side. Which is what we've been seeing.
  4. Eps overnight is now effectively advertising a transient period of favorability. With the ridging methodically retrograding to the dateline by the end of the run.
  5. Something is lurking out there around the 15/16th maybe. Looks cold after that with cross polar flow and -nao
  6. That's a solid winter pattern on the eps in the 10-15 day. 2nd half of the month looking very interesting. This is a 5 day mean.
  7. For December, top 3 looks like it's been; #1 Euro #2 UK #3 Canadian
  8. There actually is some cross polar flow into Canada on the eps. Starts building on the 14th. Looks -AO driven to me.
  9. Sure looks like its shaping up to be a very interesting 2nd half of winter.
  10. Nice post. It could be a part of a Vortex Intensification event (VI) as is described in the following paper. If so, would be terrible news for any -AO prospects. Here's a couple of relevant quotes from the paper. The life cycle of such events, if that's what is indeed occurring, can be up to 80 days. Stratosphere‐troposphere evolution during polar vortex intensification https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2005JD006302 Reduced poleward planetary wave heat flux occurs as the circumpolar wind becomes strongest and pressure anomalies penetrate toward the surface. Descending pressure patterns project strongly onto the positive state of the Northern Hemisphere Annular Mode (NAM). Between days −20 to +20, reduced poleward heat flux is observed as the vortex becomes strongest; increased poleward heat flux is observed as the vortex recovers. [41] In our preliminary examination, the anomalous vortex intensification seems to occur preferentially during La Niña conditions.
