Don't count your chickens guys/gals. It's risky to lock in a cold Canada based on a 15 day model forecast. Plenty of individual members plus operational runs show only transient cold up there. The ensemble mean makes it look like wall to wall continuous cold, which it likely won't be. Out to day 10 does not look favorable for wintry weather at the moment on the ensembles. Beyond that gets increasingly unreliable in terms of predictive value. Most of us are passionately hoping for cold and snowy. But we've seen it too often over the past few years where many here bake in unrealistic expectations based on fantasy-range model charts.

Need the cold to get the snow.

12/9/92 might be my favorite storm, mostly for the nostalgia.

SWFEs are such an easy forecast. 5-7” thump followed by slot and drizzle. Could stat padders too.

Suppression, kind of is negative interference… But yeah, either way we look at it

Some additional details on White Christmas history and probabilities across Chester and SE Berks Counties including the storm dates and snow amounts on the ground both Christmas Eve and Christmas Day.

reasoning there? supression, interference, both?

07-08 was good but not spectacular in wilmington, ma with around 70" or so iirc. maybe a touch higher like 75"? Best event was probably 12/16 in terms of impacts also iirc

Gladly take an '07 - '08 winter. Nearest coop was 93".

maybe for the mid-atlantic, which would kinda be on-par, but I'm far more optimistic around here.

In fact it would harm matters

2-3 weeks then winter is over

Many times my first acc. snow has been around Dec. 5.

Rob you and S19 will never be a D D. Our ocean hugging, UHI blessed five borough coastal plain location ensures Debbie will always be welcome in December. Stay well and hopeful, as always …..

Yep, its about the cold & pattern of the period. Obviously I posted a 7 day mean of 2013 & only one specific frame of today's 12z GFS. The system on the GFS is very similar to the system in early DEC 2013. Not making a point about the entire winter.

A generally milder than normal pattern will likely continue through next Wednesday. However, exceptional warmth appears unlikely. The closing days of November will likely turn colder. There is potential for New York City's Central Park to experience its first freeze of 2025. The 1991-2020 normal first data is November 21. The 1961-1990 baseline was November 11. Last winter's first freeze occurred on November 30. The opening days of December will turn milder. However, colder conditions could begin to develop during the second half of that week and continue through the second week of December. Severe cold appears unlikely through at least the first 10 days of December. Afterward, the pattern evolution will depend, in part, on how the imminent stratospheric warming event propagates. Meanwhile, today will be Central Park's 1,393rd consecutive day without daily snowfall of 4" or more. The record of 1,394 days was set during February 22, 1929 through December 16, 1932. That stretch ended with 6.7" daily snowfall on December 17, 1932. The ENSO Region 1+2 anomaly was -0.7°C and the Region 3.4 anomaly was -0.7°C for the week centered around November 12. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.16°C and the ENSO Region 3.4 anomaly has averaged -0.65°C. La Niña conditions will likely continue through at least mid-winter. The SOI was +31.56 today. The preliminary Arctic Oscillation (AO) was +1.436 today. Based on sensitivity analysis applied to the latest guidance, there is an implied 86% probability that New York City will have a cooler than normal November (1991-2020 normal). November will likely finish with a mean temperature near 46.6° (1.4° below normal). Supplemental Information: The projected mean would be 1.1° below the 1981-2010 normal monthly value.

No snow cover below 4500' around here, just a cold drizzly rain, low overcast becoming fog above my elevation (which is 3500'). A thin snow cover in the alpine possibly 3-5" tops.

Very short window this year for wintry wx

As long as they involve a lot of ice . South of 90 does not do well with snow in those

I think we’d all get some popcorn ready and watch Ray light up this forum.

We’re gonna end up like 2007 except shifted 80-100 miles north. We’ll be like NYC that December.

It won’t take much. Winter is on a short leash this year.

LFG

You seem really optimistic and looking forward to winter this year. I wonder how long it’ll take to break you this season.
