Not one clear/mostly sunny day in January. Other than the highest snowfall of the season to date on the 19th, good riddance.

Ended up with the 4th cloudiest January in GRR with only 8% of possible sunshine.  It was a snowy month thought with 31.3" erasing at least some of the yearly snowfall deficit.  Temps ended up 2.3° warmer than normal.  It would have been nice to hold on the the middle of the month weather a little longer.

Very mild day today with temps cast for mid 40's. Running in the low 40's atm as we are coming into peak for the day. A very mellow few days. Looks like the Dec-Jan avg is going to come in at a solid 2nd behind 1877/78 in Duluth. That sure was a warm stretch back then up my way. Too bad there weren't more stns having data from that time here across the N MN, or at least accessible. I'm sure there was some spotty data at some other sites around that time. Listing Marquette, MI at solid 3rd and Minneapolis, MN, edging 1877/78 for 1st. Strong daily avg today will bump it up a little more. An impressive winter so far. And it looks like Feb 1878 was extremely mild as well, so we shall see how it goes for Feb 2024, and what the final tally is for this winter season. 

Duluth, MN

1877-1878 - 26.6 

*2023-2024 - 23.3

1888-1889 - 22.2

1931-1932 - 22.1

1890-1891 - 21.5

Marquette, MI

1877-1878 - 29.9

1931-1932 - 29.5

*2023-2024 - 28.4

2001-2002 - 27.9

2015-2016 - 27.3

Minneapolis, MN

*2023-2024 - 28.0

1877-1878 - 27.8

2001-2002 - 26.1

1913-1914 - 25.9

2011-2012 - 25.5

 

Duluth ended at 23.6. Minneapolis at 28.2. Marquette data is still missing for the last 2 days and should end up around 28.6/7 for Dec-Jan. Interesting that Dec 1877 was extremely warm, and Jan 1878 was a little cooler. Mirrors this winter so far.

Here in Two Harbors Dec-Jan avg is tied 3rd since 1894.

1931-1932 - 25.9

2001-2002 - 25.6

*2023-2024 - 25.5

2005-2006 - 25.5

1997-1998 - 25.2

1913-1914 - 24.8

As said, it was the wettest January on record for Detroit, pretty much unheard of for a strong Nino.

01.) 5.25” – 2024  
02.) 5.02” – 1932  
03.) 4.96” – 1874  
04.) 4.38” – 1950  
05.) 4.31” – 1916 

 

The 17.0" of snowfall didnt make the top 20 (this ranks as 27th snowiest), but definitely a win considering the nationwide pattern.

 

Skycover averaged 9.1/10, a powerball-special cloudy month. This is reflected in temps as well. The mean temp of 27.5F is +1.7F, but the breakdown was high 32.2F (-0.1F) and low 22.8F (+3.6F). The spread of max/min was 44F/-3F.

New Years Eve. Yeah, surprisingly good score for DTW. Big month here as well with 31.7"  

I never know where you are gong to pop up next.  You sure do move around a lot.  Welcome back to the GRR forecast area where you can be negelected almost as much as the Battle Creek area.

Im wondering if this is similar to 1877-78, where the core of the warmth was centered in MN/the Plains? While it was certainly a mild winter here in 1877-78, it wasnt nearly the magnitude of out there. To date, 1877-78 stands as Detroits 16th warmest winter on record. Other winters of that era of up-and-down winters that rank higher on Detroits warmest list are 1881-82, 1879-80, and 1889-90. The warmth and lack of snow in 1881-82 & 1889-90 is FAR more impressive here than the mild winter of 1877-78 which actually saw slightly above avg snowfall. While December 1877 is Detroits 5th warmest on record, January and February 1878 dont even make the top 20. Meanwhile, there is tons of documentation and stories about how wild Minnesota's Year Without a Winter was in 1877-78, and it appeared even worse in Duluth than Minneapolis. (Duluth was warmer than Detroit in Feb 1878!)

 

And same here. The warmest temp this January at DTW is 44F. Only 29 years of the 151 years on record saw a lower max temp in January.

 

 

How much snow did Detroit receive in Dec 1877? Dec 1877 is the least snowiest ever on record here with only 0.3". Dec 1877 is the 7th warmest on record here. 2015 and 2023 take the cake for top 2 though. 

1889-90 was the warmest of the 4 winters you mentioned with a mean DJF temperature of 30.3F in Toronto. I haven't looked at the warmest/coldest winters in Toronto yet. I only have for YYZ (going back to 1938). The 30.3F would make 1889-90 the 4th warmest on record, behind 01-02, 11-12, and 15-16, respectively, since 1938. 

However, temperature records, especially over the last 30-40 years would definitely be impacted by UHI and urbanization, especially overnight lows. I don't know how applicable this principle would be for Detroit, but most major weather stations are either in the city or at the airport which can cause a "heat island" effect. Not trying to discredit climate change here though. 

But seeing how warm some of those 1800 winters were that you mentioned, in a time where there was no "industrial revolution" or "UHI" is pretty impressive.

I see no evidence of this in the data. If anything, Detroit used to run more above the surrounding observations in 1890 than it does today. People act like it was some pristine wilderness back then. Detroit already had a population over 200,000, increasing to nearly a million by 1920.  The city stations were often sited either on heat-contaminated rooftops, or on heat-contaminated window shelters. And there were large blast furnaces spewing copious amounts of heat and pollution in many of the cities. Furthermore, most of the so-called urban heat island effect is explainable by the fact that cities developed along river valleys and/or lake/coastal Plains, whereas the suburbs and rural areas tend to be situated in elevated upland locations away from these features. Of course, rural/ex-urban White Lake (elev: 1,000'+) is going to be cooler than Detroit (elev: 660 feet).

Here's December 1889. Detroit was about 3 degrees warmer than the other two Wayne County sites, 3 degrees warmer than Ann Arbor, and 4 degrees warmer than Ypsilanti. KYIP usually runs warmer than Detroit Metro Wayne Airport, and none of these locations are that much cooler than the airport. There were only 3 warmer locations - Chelsea (Washtenaw), Hanover (Jackson), and Benton Harbor (Berrien). The first two clearly have solar radiation issues, as their high temperatures are WAY out of line with the other sites. Benton Harbor is on the other side of the State.

Dec 1877 had 1.9" snow but 1.6" of it fell on Dec 1st.  The other 0.3" fell on the 6th. Funny thing about 1877...it had two unusually snowless winter months. In Feb 1877, only 0.04" precip (driest Feb on record) and 0.2" snow fell. Unlike the mild winter of 1877-78, however, the winter of 1876-77 was very cold in Dec/Jan then a crazy swing to torch in Feb. 

 

Its no surprise that acknowledging warm winters that occurred in the old days does NOT sit well with TCC, and he has posted 1800s coop data to discount the official data, where often times a coop was usually a farmer that would record temps 2 or 3 times a day, as most didnt have a max/min thermometer. Coop data is full of errors today, I can only imagine its accuracy 140 years ago :lol:. I guess the golden rule is use all cold/snowy data from the old days but discount the warm/snowless :rolleyes:. No one here denies a gradual climate warming overtime, but the stretches he takes to discount any old warm winters/hot summers, or downplay any current cold snaps, cold/snowy stretches is really over the top.

 

There is PLENTY of documentation about the warm winters of 1877-78, 1879-80, 1881-82, 1889-90. And locally, 1881-82 & 1889-90 were extraordinarily free of snow. I have attached an article from the December 26, 1889 Detroit Free Press discussing the weather, but also take a look at the rankings of those 4 winters. They all rank very high on everyones list.

 

Rankings of those winters in terms of warmest:

11.) 1879-80

LOL. 1889-90 is probably the warmest winter this region as a whole has seen, but lets discount it. BTW, KYIP ran warmer than DTW when there was a temp sensor issue, which has been fixed.

Not THAT much. I was in Marshall nearly 20 yrs (02-21), then Metro Detroit 2.5 yrs. I could stay here just fine and hopefully will. Middle of the Mitt and basically everything within a few hrs drive (or less).

How close are you to Mid Michigan College?  We have done some road and MTN Biking around there.  Nice area!!

I didn’t say anything about 1889-1890 not being warm. The claim was made that there was no urban heat island effect or industrial revolution in that era. All I said was the data would indicate there was a significant urban heat island effect, and my knowledge of history would indicate the industrial revolution was in full swing by that point.

Unfortunately, we'll never know how much fell at Toledo and Cleveland since there were no snowfall observations.

Cleveland

Oh, I forgot about this storm. I have read of it before. Likely, the biggest snowstorm observed in Cleveland, but official snow records don't begin until 1893. There was a volunteer who observed weather from 1855 - 1905, including snowfall. He reported 22.0" of snow, on 1.98" of liquid precipitation. 18" were said to have fallen in 8 hours, including a fall of 4" in one 20-minute period.  This exceeds the 21.4" which fell during the "White Hurricane" of November 1913.

Anyways, I wouldn't take the snowfall numbers as gospel, since they were likely based on a single daily measurement and without the use of a snowboard. But several of these values would place favorably among the official records since 1893. Most notably, the 101.8" in 1880-81 would still rank as second snowiest of all time. The 22.6" observed in 1865-1866 would rank as 3rd least, just ahead of last winter and 1894-95 (22.7"). Also, the 0.2" observed on September 30, 1888 would be the earliest measurable snowfall on record in Cleveland, and the only time measurable snowfall has ever occurred in the month of September. The official record is the 0.3" observed on October 2, 2003. The 1.4" in May 1875 would be second most for that month. The 36.4" in December 1886 would be a record value. Several other of those months rank in the top 2-5 on both most and least snowfall.

His average of 53.2" is probably underdone for the reasons I noted. But the current 30-year normal is around 63 inches. However, the moving 30-year average is down to about 54", the moving 10-year average is down to about 40" and the 5-year average (constituting the whole of the 2020s from 2019-2020 to 2023-2024) is down to around 33". Obviously, these values can come up a bit depending on how the remainder of the winter plays out, but not much. Even an unlikely two feet of additional snow from now through April would move the 30-year up by a fraction of an inch, the 10-year by 2.4" and the 5-year by 4.8".
