Record warmth prevailed across Minnesota yesterday, with record highs of 56F at Minneapolis-St. Paul and 55F at St. Cloud. Fargo reached an incredible 60F, setting a daily record and making yesterday the 3rd latest date in the calendar year on which that temperature milestone was reached or exceeded.

If not for that piddly 0.2" on April 9, we'd be near our longest stretch without measurable snow on record right now, as that was the only measurable snow after March 8.

Even better elsewhere, back when there were more official snowfall observations. Morgantown came in with nearly a foot. Northern Pennsylvania got clobbered. The daily reported snowfall on the 11th appears to have been so high at DuBois, it got automatically rejected by the automated rejection feature for suspect readings in xMacis. A review of the daily snowfalls and change in depth suggests over 2 feet fell, with depths peaking at 34" from the 12th through 14th. Bradford had a peak depth of 39 inches.

Certainly, a great way to break a snowfall drought with nearly 10" of snow at the airport (looks like there may have been some mixing?).

I didn't say anything about a torch. Just asked a question as bluewave's map of the Euro weekly showed +1 to +3C across the East this week (11/24 to 12/1).

Interesting look here. 10 warmest Novembers, minus 2009-2010 (significant ENSO mismatch) and 1913-1914 (age). Rather similar to CPC's outlook, except they are a bit more robust with the cold extension to the southeast.

The current three warmest Novembers are 1999 (+5.14F), 2016 (+4.98F), and 2001 (+4.42F). 2025 looks like it will be in the mix with these years. Rolling the 3 warmest Novembers forward through meteorological winter, here's what that analog map looks like. 1999-2000 is 3rd warmest of all time, 2016-2017 is 9th warmest, and 2001-2002 is 10th warmest.

I thought there was supposed to be a big cold snap around Thanksgiving?

Looking specifically at Erie, the low end GLERL projection would bring lake levels down to 173.78 meters by late winter, which has only been reached or exceeded twice since the mid 1960s on a monthly average - 173.78m in March 2003 & 173.75m in February 2011. That's going with the low-end projection, so it might not happen, but certainly a stark contrast from the near record high levels of 2019 & 2020.

Do you think the atmosphere is still capable of producing 4" of snow in a single day at locations like New York and Pittsburgh (see below)? I noticed Pittsburgh has obliterated its longest stretch without 4" of snow, and this includes data from the downtown station that was a few hundred feet lower in elevation with a seasonal snowfall average of about ~12 inches less than the airport. So this is completely unprecedented since at least the 1870s. I have to wonder if the 40N parallel is simply too for south to see such heavy snow with the current atmospheric conditions? Maybe NYC will fare a little better being on the coast?

It's been an incredible 1,348 days since the last calendar day with 4" of snow. You have to think eventually that breaks, or do you guys think it is no longer possible to see 4" of snow in a single day at PIT?

Yes, it's warmer today. But the 1930s were quite warm too, especially in North America. So warm, in fact, that certain people like to constantly bring them up to "rebut" climate change. A few notable cold snaps don't change that fact. New York City's moving 30-year mean annual snowfall was pretty steady between 32 and 34 inches until the mid 1920s - and that's generally with measuring the new fallen depth, not snowboards and 6 hourly or more frequent measurements. So, the "snow drought" from the late 1920s and early/mid 1930s was certainly a big departure from the long-term climatology.

And the current snow drought is WAY more impressive than that one. Maybe there weren't any 4" snows, but there were certainly more 1" snows. NYC has seen ~50% less snowfall over the last 3 years than it did from 1930-1932. Even the 3-year period from 2022-2024 saw a little more than 10% less than 1930-32. Note the 1869 value shown below is for 1 year only.

The entire premise is incorrect. There was plenty of climate change back then. CO2 concentrations were already up to 310 ppm by the early 1930s, compared to a pre-industrial mean of 270-280 ppm. And methane was already up to ~1100 ppb, from 700 ppb pre-industrial average. CO2 follows a logarithmic curve, so the amount of warming from the early/mid 19th century to the 1930s would be about the same amount of warming that has occurred since 2000 - actually more significant when you factor in methane concentrations. There is nothing in the history of New York City to suggest that the snow drought during that period would have occurred in the absence of human caused warming.
