I used to live in Duluth, and will never forget the Halloween storm of 1991. Anyone else remember? I THINK we had 2 feet or so. It was also very early in the season for this type weather, even in Duluth. I also remember sleet as late as Memorial Day one year.

Theres a Weather History Thread. I would love to read a story on that and how the storm came together and see pics. Post it there so we dont go off topic since this thread is for upcoming winter.
You know that song...Let it snow, let it snow, let it snow?
Well, I'm singing... let it melt, let it melt, let it melt..... But I'm not talking about the snow..
A study done from Rutgers shows the warming of the Arctic and the sea ice melt will lead to slower more locked in patterns for December, January, February.
A fan of winter in the East will like the trough of cold air they show dipping down into the Plains, Great Lakes, and NorthEast.
I've been wondering why the ridge has not budged from the West since July. Maybe this has something to do with it because its helping create blocking also...
If you love high latitude blocking, stormy weather conditions, and an active winter weather pattern; then you love these observations this morning!
The stratosphere as a whole is starting to show signs of moderation as a whole, but again what has my attention is where the anomalies are setting up.
For the second straight week, the warmest temperatures at 70 MB, 50 MB, 30 MB, and 10 MB are focused over Alaska including the Aleutian Islands and eastern North America which strongly supports a 500 MB pattern that features a persistent negative EPO, negative AO, and negative NAO weather pattern over the northern hemisphere. Also note the cooler anomalies over Greenland and northeastern Canada along with cold anomalies over the West coast. These anomalies strongly point to enhanced heights in these locations.
Why are these anomalies important? These stratospheric anomalies tend to start to lock in to place this time of year and are heard to change unless a major stratospheric event takes place. For example, a very powerful solar flare that cools the entire stratosphere of the Earth due to ozone destruction. Some like that would be akin to a powerful earthquake which are typically rather rare. So when combining these observations with a negative QBO impact on the stratospheric wind circulation, you can clearly see that high latitude blocking is setting up to be a significant influence on the weather pattern for the Fall and likely for the Winter.
I am surprised this hasn't changed yet. Drawn 9-20, a good swath of the Midwest is still expected to be above normal for temperatures. This is for Dec- Feb. I haven't noticed any other changes to predictions from a month ago.

Morning. If possible, screen shot the image because that link will change with each update and we wont have a file on what it showed today, which is no below normal temps anywhere in the U.S except southern Florida and southern Texas. .
