Introducing The GMWeather Model ❄️
I found the 10 past winters that look most like this one, pulled their real snowfall totals, and blended in the Euro model.
The verdict: Virginia and the Carolinas lean snowier, and the Great Lakes lean less.
It's a lean, not a guarantee.

NOAA released the new Coastal Ocean Reanalysis (CORA) dataset for the U.S. West Coast, Hawaii, and southern Alaska, and a new Experimental High-Resolution High Tide Flooding Outlook. This dataset and Experimental Outlook advance NOAA’s ability to better serve our nation’s coastal communities by providing data to support coastal flood planning and mitigation efforts.

The last strong El Niño winter with a November polar vortex disruption was 2009–2010, which ended up colder than anticipated, with December bringing bitterly cold conditions across much of the country. This is just one analog for temperatures in December that year, but it shows how big of a wildcard the polar vortex is in winter forecasting. This potential Sudden Stratospheric Warming event is getting so much attention because it could be the earliest on record during a strong El Niño. I would lean toward a quick start to winter this year.
Meet and greet this Sunday in Cedar Rapids, IA! Meet and discuss this topic with me: facebook.com/share/1LocV3yKi…

This is a very interesting look in the long range. All ensemble guidance agrees. Blue is a trough & could bring storminess & the potential for cool to cold air. These are the type of looks we are going to need for us Winter weather fans deeper into the cold months. Watching mid November.
I know, you ain't got to tell me.. it's way out in range. But I find it interesting all ensemble guidance basically agrees.

Such a stable looking GFS run with the SSW (shown here at 30mb). Model runs will vacillate, but this one was a biggie with a SSW on Nov 4 still going at Nov 13

Massive polar vortex disruption will cause an Arctic outbreak.
See below at the Arctic outbreak on the way.

Let’s continue our look back at some of the most memorable Carolina winter storms!
February 12, 2014… aka SNOWMAGEDDON. 🚗❄️
Raleigh only got 3.7" of snow. Somehow, that was enough to turn every road in the Triangle into a parking lot. The snow started mid-morning, everyone tried to leave at the same time, and commutes that normally take 20 minutes turned into hours. People abandoned their cars on the side of the road and just started walking home.
Charlotte picked up 8.4" and Greensboro 9". Parts of Surry County got as much as 17". Down in the SC Pee Dee it wasn’t funny, with up to 1.5" of ice and around 350,000 South Carolinians losing power.
On a more personal note, this forecast was a complete bust for Pickens, where I grew up. It was one of the big storms that really sparked my love for weather!
Were you one of the brave souls stuck in it? Or did you watch it all unfold from the couch? 👇

This WINTER Will Bring HUGE Snowstorms.. But For Who?!

That is a big ole jumbo trough up in Canada. We saw this a lot last Winter & often times it led to cold air dropping further South. This is something to watch as we wrap up October & move into the first few days of November.

It was a "see Charlotte from the Blue Ridge Parkway" kind of day.
Crystal clear visibility, you could even see it with your naked eye.

This East Coast low isn't a hurricane — but it might start acting like one. I just broke down tropical vs subtropical vs extratropical, what Sandy and 1938 teach us, and what I'm watching this week. Watch Here: youtu.be/VoT4L-pGkN4

No modern El Niño event remotely compares to how far east the *mean* Indo-Pacific Warm Pool (IPWP) currently is in the Equatorial Pacific
Remarkably, the mean IPWP is currently shifted ~15 degrees east of 1997-98, the modern gold standard for an “east-based” El Niño event

First snowfall for Caribou, ME of the season. It is accumulating on cold car surfaces and grass. #mewx

This gives me Winter time flashbacks where we are praying & hoping for a last second NW trend. What a trend for this weekend. About to go from a Sunny blue sky Fall weekend to a spooky cloud breezy Fall weekend.
Some might love that, some might hate that.

Euro was on an island. Now it’s not. CPC held strong & it looks like they made the right move. We will see how we trend early this week.

A beautiful weekend is ahead for the Southern & Eastern sections of the country. Cool crisp Fall air will move in for a couple days. Snow will even be possible in New England. This mixed with Fall colors will offer the opportunity for snowliage!

Will it be a snowy winter? Here's what the latest data shows! ☃️
A record El Niño will bring ample moisture to the U.S. this winter — outside of the Pacific Northwest — but that moisture won't always be met with cold air.
That's especially true in December, when the Northeast and Great Lakes are confidently predicted to have less snow than average.
On these maps, areas with a dashed outline mean that five out of six models agree on the outcome shown, which conveys confidence. These maps are best interpreted as a broad estimate of winter snowfall patterns, rather than a precise forecast for any one location.
From December into January, a signal grows for more snow than normal across the West and Plains, stretching from California's Sierra Nevada to Denver and maybe even Dallas.
There's also a bubble of above average snow that develops over the southern and central Appalachians, including Atlanta, Columbia, South Carolina as well as Charlotte and Raleigh in North Carolina.
A similar snow signal continues into February.
Although there's a relatively strong signal for less snow than normal across New England all winter, the rest of the Northeast is a more interesting case.
There will likely be many big coastal storms which could bring rain to the coast but the potential for significant snow inland.
These "high ceiling" storms appear to be a wildcard in the winter ahead.
It will all depend on whether there's enough cold air in place to cash in on all that moisture as snow.
