Hat tip to user @PhiEaglesfan712 for noting this over in the ENSO thread. This proves definitively that this has been, by far, the worst decade ever to be a Mid Atlantic snow weenie.

As we approach the 10-year anniversary of the Snowmageddon of 2016, the 10-year moving sum of snowfall is set to absolutely plummet to levels never seen before. Effective January 23, 2026 (covering January 24, 2016 to January 23, 2016), the moving 10-year total snowfall observed at Washington, DC and Baltimore, MD is set to plummet to 75.6" and 95.3" respectively. This will obliterate the prior records of 92.8" and 123.1" respectively, which occurred from the last year on all dates between the last snowfall in February and the first snowfall in December.

I think the most surprising thing is even with that 30" + storm on the books, they've been straddling the record low 10-year snow. That's why once it drops off, it doesn't just a set a new record low - it absolutely obliterates the prior record.

I suppose the Baltimore tally which is set to obliterate the record by nearly 30" is probably even more unbreakable. Really bad time to be a Mid-Atlantic snow weenie - that's for sure!

I confirmed manually that no additional snows fell in January 2016 after snowmaggedon at any of the sites, so these values would be the rolling 10-year sum [even on a daily resolution] effective January 23, 2026 (covering January 24, 2016 to January 23, 2026). A rolling 10-year sum of 75.6" [equivalent to an average of just 7.56" each 12 months] at DC, assuming no measurable snow through Friday, seems like it would be difficult to ever break. Maybe an unbreakable record?

And at Philadelphia. The record sorted by month end is 144.1" from March 1, 1922 to February 29, 1932. Last year saw the second lowest at 146.1 inches. Looks like 15.6" is needed to avoid the moving 120-month total record low. Not sure about 10-year daily moving totals - probably similar to these. Almost certainly, the prior record belongs to one of these periods, but might be a little bit lower than these totals, since it's on a daily metric (and this analysis is limited to discrete days - end of each month).

For Baltimore, the rolling 120-month total is currently at 95.3" (February 1, 2016 to January 18, 2026). The record is 123.1" for every month from March 31, 2025 to November 30, 2025. Baltimore would need nearly 30" of snow the rest of the month to avoid a new record.

xMacis can sort by years, months or days, but that many days overwhelms it. When sorting by month or year, it defaults to the last day of each month or calendar year, so daily resolution is not available. With that said, if no more snow falls this month, the 120-month rolling total (February 1, 2016 to January 18, 2026) would be at 75.6" at DC if no additional snows fell this month. The current record is 92.8" ending every month from March 31, 2025 to November 30, 2025. DC would need 17.2" to avoid a new record by month end rolling. Probably the same for the daily unless some additional snows fell in 2016 between the snowmaggedon and the end of the month.

Averages start climbing again in a few days. Interestingly, under the old 1981-2010 normals, highs started climbing today (35.4F on the 17th, to 35.5F on the 18th).

Snowing at a good clip in my backyard. Sticking quickly.

It's been a great winter for Central Ohio. Since 2014, only 2018 saw more to date at Columbus!

Heavier "squall-like" snow showers possible tomorrow on top of the light snowfall tonight.

Thank you for the comment. The official values for Chester County show more warming over that period. It looks like your numbers start near the NOAA values and then drift lower over time. Not sure how you are correcting for changing station basket or is this only comparing one or two sites.

Shows up really well on the rankings too, with almost every station out there seeing its warmest winter to date.

This has been a very favorable pattern for the eastern U.S. overall since December 1. You can see departures in the intermountain west as high as +16F to +18F for the winter season to date. Really can't complain about this look. Could be a LOT worse.

Views like that, and snow like the above... count me in!

Two days after making us ground zero for the fantasy snow blitz, the GFS has decided to make us the screw zone of all screw zones. To be clear, 8" over 16 days isn't horrible, but it would be pretty awful if everybody else in the northeastern US got 2 feet +.

Both of these pale in comparison to South Bend, which saw 12.6" yesterday - the most in nearly 11 years (February 1, 2015; 14.7 inches). To put the amount of snow that fell in South Bend in perspective, Detroit has only observed two days with more snow than that since 1908 (18.4" on 12/1/1974 & 13.7" on 2/1/2015).

Incredible! The 5.1" calendar day snowfall at Detroit yesterday was the most in a single calendar day in nearly three years! The last time more snow fell in one day was March 10, 2023 (5.2"). Even more impressive, the 7.2" calendar day snowfall at Cleveland today was the most in almost four years! The last time more snow fell in one day at Cleveland was February 3, 2022 (8.0"). I'm sure many have been waiting for days like these for a LONG time!

Moscow is not warmer than Detroit. It is significantly colder, moreso in the summer but winters are colder too. The mean daily maximum in January is only 25.0F, which is less than the mean daily mean [average of max & min] for Detroit (25.8F), with the daily mean being 5F colder (20.8F). For the year, it's way colder. The normal annual mean is 3.6F colder than even Minneapolis. A normal year in Moscow (43.3F) is 0.7F colder than the coldest year ever recorded in Detroit (44.0F, in 1875). The difference is greatest in the late summer. The normal August in Moscow is 2.2F colder than the record coldest August in Detroit (65.9F, 1915) and the normal September is a full 4F coldest than the record coldest in Detroit (57.4F, in 1918).

Surprised nobody shared the 2025 global numbers. Most temperature datasets say 3rd warmest, slightly behind 2023, although NASA's GISTEMP narrowly edged out 2023 for 2nd warmest. 2024 is the unanimous #1 in all major datasets.

Not looking forward to this cold next week. Wish I could book a trip to Florida until it passes. Let's hope those 300-hour projections are way off the mark.

Very 1932-esque out there.

Pretty strict size limits. I rarely post pictures, but for images I usually upload to imgur and then link.

Can sort of make out that one heavier band the NWS was concerned about possibly making it into eastern Ohio and perhaps parts of Washington County. Nothing too heavy in our immediate area otherwise. Lake enhancement certainly helping out around Cleveland and points east of there.
