..but the past can help to predict the future. 100% accurate??..no it is not but it certainly can provide a good baseline for where things may be heading.

Of course.  I'm not saying it can't or doesn't.  What I'm saying is that if we average 9 inches of snow by January 15 and 29 inches overall, then the benchmark for the period from January 15-end of winter is 20 inches.  Not to pick on Don, since he's one of the best posters on here (and the story doesn't actually completely change), but his post a little while ago is a good example.  Those snowfall totals should be compared to normal post-Jan 4 amounts to determine whether bad Decembers predict bad winters...not compared to normal full season amounts.

if people looked for what could only go wrong, snowstorms would literally never be forecasted

Dec 2010 was thread the needle, Jan 2016 and Feb 2021 had too much confluence and so on

it's important to acknowledge periods of higher potential

I'm talking about in the longer range. Most snowstorm threats that are 7+ days out on the models fail. Snowstorms should only be forecasted when they get to the more accurate/reasonable day 5 range, IMO.

I know, but nobody is forecasting a snowstorm... people are only addressing a threat, which is also important. there is certainly a threat or two next week, mainly for the one towards the end of the week

if people assign unreasonable expectations due to those threats, that is on that person IMO

Yep. We know that most snowstorm chances fail for our area, so it's best to look for what could go wrong rather than what could go right. I like Anthony's enthusiasm, but he's always looking for what could go right rather than what could go wrong and that leads to disappointment most of the time. 

I'm not looking for enthusiasm all the time. The pattern doesn't look bad at all. 

There is a legit storm threat mid month . That's all we can ask for.

Temperatures across the area are soaring to near record and record highs. Yet another day is passing where snow-starved New York City and Philadelphia won't see any measurable snowfall. The larger Boston, New York City, and Philadelphia corridor is currently passing through a fairly novel situation.

Beginning in the 1990s, winters with very low snowfall in Boston, New York City, and Philadelphia through the end of December began to appear. Winter 2022-2023 became just the 5th winter beginning with 1893-1894 where Boston saw less than 2" of snow and both New York City and Philadelphia had no measurable snowfall through January 4th.

The sample size is very small, but most of those winters went on to see below normal seasonal snowfall.

Could things be worse? Perhaps.

Since 1950, Winter 2022-2023 became only the second winter to see no measurable snowfall in both New York City and Philadelphia when the Arctic Oscillation (AO) was negative for all 35 days. The other winter: 2001-2002.

During Winter 2001-2002, the MJO passed through Phase 8 during January 4-9 and Phases 8-1-2 during January 4-18. Temperatures remained generally mild.

Phase 8 passage: Boston: 39.3°; New York City: 39.7°; Philadelphia: 39.5°
Phases 8-1-2 passage: Boston: 39.8°; New York City: 42.4°; Philadelphia: 43.4°

During the passage through phases 8-1-2, New York City picked up 3.5" of snow and Philadelphia saw 4.0". And that concluded the snow season for both cities. Boston limped to a seasonal total of 15.1".

For now, even as the odds are increasingly tilting toward below normal snowfall, a disastrously low outcome isn't the most likely scenario. Indeed, some guidance supports at least the potential for some snow by mid-month. But that's guidance. Things can change. Finally, even as it isn't the most likely outcome, a disastrously low outcome cannot be dismissed outright.

 

So basically and unprecedented El Nino storm or a gutter ball!

 

I’ll go with the gutter ball at this point. The question is how low will the snowfall total be?

Crazy warm today. Already up to 67.5 in Fort Salonga. All the models seem way under on the forecasted temperatures.

Until mid spring models usually under forecast warm spells like these. Warm down sloping winds and lack of evapotranspiration from leafed out trees (unless models have been upgraded to account for this). In this case the much warmer than average waters probably help quite a bit.

RGEM and GEM-LAM nailed today's temperatures. They were the only models showing 60+ temps for LI, until the HRRR did as well. They were the only models showing the possibility of 70+ degrees in NJ
