  1. We still don’t if the mjo will be enough to flip the pattern. It’s a very strong wave so their is reasonable hope for it. But unfortunately the mjo isn’t the only factor currently
  2. The olr maps are more accurate and have p7 around Christmas then p8-1 to end the year into 2022
  3. Those rmm plots chase convection. We are still currently in p6
  4. Phase 7 effects won’t be felt until closer to Christmas. Any phase 8 impacts will be after xmass. The only wildcard is some strat hits on the Pv around the 20th that could help with a cold shot in that timeframe.
  5. Need to continue to see trends of the pna relaxing. Nice trend in that area over the last few ensemble runs
  6. Eps overnight was hinting at some front end snows for the 20th
  7. Nam keeps temps in the upper 50’s/low 60’s today.
  8. Incredible historical event. Very sad stuff.
  9. Crazy snow gradient around msp last night
  10. Ensembles getting colder in the 11-15 day as the -pna is less stout and stronger -nao
  11. Last three days at the park have been below normal with yesterday having the largest departure of -6. Didn’t get out of the 30’s yesterday.
  12. We need to start seeing changes (moving up in time) somewhere and this is a start….I’ll take a -epo and East based block and roll it forward from there…
  13. Looks like the high was 37 at nyc? That would be below the forecast high of 39
  14. Ehhh, maybe. Would really need that nao kick back the se ridge
  15. Eps and GEFS agree on the -nao/-epo combo but that -pna is going to be a problem
  16. December 2017 into January 2018 was our last real stretch of artic cold temperatures
  17. Next week still looks mild but the 70’s talk might be a stretch. The weekend is now looking to be the warmest on the models. The highest temperature next week at nyc is the upper 50’s
  18. It’s going to take a major hit but will probably regain strength after that. It that wave 2 hit is true, it could help improve the pattern for cold/nao
  19. -epo continues to move up in time on the ensembles. The Pv looks to take a hit around that time which might allow for a -nao. It will take time but after next week’s blowtorch I do see some positive signs
  20. We have had a +pna last week
  21. 42/34 in the park yesterday. Should be another below normal day today. Models did a good job forecasting this cold shot
