Chaotic Pattern Change! For the last few winters we have had a standard tip bucket. The Arctic basin fills up with cold air, and spills our one of the gates. I had it all figured out.
Now, I have to figure it out all over again.
It's gone into a slow creep, where the upper winds are no longer associated with the lower winds.
You can't see any lobate fronts in Canada, but they form in the US. Greenland does not want to go black, but a lot of black in Canada. A huge flow from the Arctic, but it turns right away to the East without any apparent forces.
The weather forecast had a warm and rainy Christmas day for Toronto, but every day the forecast gets colder. It will soon be snow, since I can't see any heat. My general forecast is a very cold winter, since we have no heat sources. Right now, I'm inclined to think that it will just come in slowly.
ps The Whole Arctic Vortex is back. It has a huge low-pressure zone in the middle. That is why the spill that should come down on Canada is diverted.
Since this is a new thing, I have no idea what is going to happen.
