Interesting. My phone has 5.2 inches of snow for Pittsburgh on Thursday. Also, another 2.15 inches of snow on Friday (not shown).

The map is for meteorological winter (December - February).

Slight risk of heavy snow the week of 11/21.

It's starting!

I mean, of course, there's going to be some lake effect snow. But Buffalo's snowfall total of 71.3" was 24.1" below normal. Other locations were far worse - Erie had its 4th lowest snowfall on record (24.8") and Cleveland its 7th lowest on record (25.7") - the latter just one year removed from its 3rd least snowfall on record (22.7" in 2022-23). Both years being the lower than any winter since 1931-32. Rochester's total of 52.5" was 13th lowest on record, one year removed from its 10th least snowy winter on record (50.4" in 2022-23). Both of those totals were least since the winter of 1952-53. Doesn't matter how warm the lakes are if there isn't sufficient cold air. And northwest flow events have seemingly gone extinct in the last several years.

They are not wrong.

Incredible. 1.3" more than MDT has recorded since January 25, 2023, a period of nearly 22 months.

Through the first third of November, PIT is running a whopping 10.2F degree surplus relative to the normal. Needless to say, we are building a considerable separation between the prior warmest years in the threaded record. Now, 0.6F warmer than 1880 and 0.9F warmer than 1921. 1921 is the current warmest year at 55.4F. In 1921, there was an impressive cold snap in mid-November, then the second half of the month was largely a "blowtorch." December saw fairly typical temperatures. 1880 was bitterly cold in the second half of November and the entire month of December, so it quickly plummets in the rankings from here on out. Almost looks like a lock for warmest year on record, and we could do it by more than 1F over 1921 if December is mild.

Mostly just a result of the fact that they added about 1.5F to the calculated mean for each month in the 1991-2020 normals for Toledo. The 1991-2020 mean for October is 53.1F for both Toledo and Detroit, so if they had just used the average, it would be +3.4F at Detroit and +3.1F at Toledo. If you look at the data, you'll notice a disconnect began in late 2018. What I think happened is the TOL ASOS was reporting too high during that period. While the normals are often thought of as averages, they are not. They are smoothed and normalized, but NOAA also makes adjustments based on pairwise homogenization. So I think the normals for Toledo got incorrectly adjusted upwards based on the warming in the last couple of years of the climate base period, which I believe was likely just due to a bad sensor or perhaps a problem with the fan/aspiration. The adjustments make sense if they are based on a change in equipment, change in location of the observation site, or a growing urban heat island effect, but can be unrepresentative if the changes result from an equipment problem that is corrected after the fact. In the case of TOL, the ASOS was down for much of the month of August. It's clear that since that change, it's been reporting temperatures more in line with surrounding locations.

Same here. I’m out in the woods. So eerie for November, when you’d typical expect it to be like 40F at this time of night.

Surprised it wasn’t even higher. It was 85F at Dunkirk, New York yesterday. That’s hot for there for anytime of the year. Nearby Buffalo has seen 4 years where the temperature didn’t even reach 85F, and 5 others where the maximum reading was 85F. Thought that superheated airmass descending over the mountains might be able to reach 90F.

85F in Dunkirk, New York. Wow, just imagine how hot this superheated airmass in the Coastal Plain. Maybe some 90s tomorrow?

85F in Dunkirk, New York today, just off Lake Erie. That’s warm for July.
