The Pacific is so low in heat energy that the plumes can no longer penetrate North America. In December, we had the mild plumes hitting Vancouver straight east, and going right across the continent. This was mild weather. Then we had big hits up at Alaska, but the plumes could only go partially in and then the cold deflected the plume downward at a 45 degree angle, to the south-east. It dragged cold air with it, and it was an Alberta clipper.
Lately, we've had weak plumes slashing down the west coast, and bringing up warm Gulf plumes. This was our alternate warm and cold times.
Now, we aren't getting any of that. The plumes can't even hit North America. They just flop around in the ocean. However, I am sad to say that a monster cold incursion is starting. You can see the cold, clear air starting to hit the provinces.
These monster air glaciers are just driven by their own density, and/or being pushed from the other side. This is another Texas freezer. Nothing will stop it. Of course, we have endless uncertainties, but the 80% chance is something big.
The warmth has allowed some natgas to go back into storage. This got everybody excited and the price went down. When Cold Blob #5 hits, the price will go up to $11 bucks. You can follow its progress on the channel "All cold, all the time.", my favourite tv. :)
This isn't over, so if you are in Huntsville, just plant your tomatoes June 1. We'll have snow and frost all May. The philosophers will come up with some explanation after the fact, like La Nina. They've been doing that for years now, and everybody just gobbles it up. Good for them!
The essence of the Scientific Method and a working hypothesis is that you can predict response to forces. You can't do that with philosophy, and you make up 'Just So" stories, like how the leopard got its spots. It makes great tv.
ps. I was in Huntsville for the last few days. Very pretty walks, but I wrote nothing that nobody had to read. :)
pps. normally this time of year, the plumes would be travelling all over NA, demolishing the cold blobs.
more: Looks like this blob is only giving us frost, and solar energy is beating it back.
evenmore: snowblower is going, lawnmower coming out.
