  1. This is what I mean with the ridge moving west and establishing a cross Polar flow/-epo. All the ensembles don’t roll the ridge over which would pump the southeast ridge.
  2. I think our best shot of snow will be as the pna ridge starts to retrograde west into Ak. This will allow colder air to enter the eastern US. With a active southern jet and colder air in Canada we will have our chances. I welcome this pattern change as it’s diff then anything we have seen in the last two years.
  3. I think our best shot is when the pna ridge starts to move west. It will allow colder air into Canada and the southeast ridge will still be a bay, at least at first.
  4. You’re definitely correct. It’s starting the fade the Aleutian low as hgts back into Ak. That could be good (see GEFS geps) or its a bit muted like the eps. Just need to see if it goes further west into the Aleutians which would be standard Niña. This might be a response from the mjo getting into p5/6
  5. Could make the end of December and January colder if it continues into the colder phases.
  6. The first one off the pna spike will definitely go west of us. After the 1 week of December I believe are chances of a snowstorm will be higher. The one around the 5/6th is our first chance.
  7. Yeah. Definitely. Ventrice thinks it might be from a Siberian ssw?
  8. Crazy. It only took two years of waiting. What is causing this look? Warm pool off the west coast? Mjo in cod?
  9. @Isotherm what do you think is causing this niño response? Mjo with weak convection in P7? Or the warm pool off the west coast? Aleutian low/++pna/-nao is textbook niño December
