Looks like the snow threat crapped the bed tonight, but the temp crash has still been impressive.  Most areas have crashed over 50 degrees already from 8-9 hours ago, with wind chill values making it feel over 60 degrees colder.  

Moline was a record smashing 79 yesterday, they are now 17, wind chill -3‍

Looking at the Michigan state record high for the month of February...

Isolated data pre-1888, although the data we do have covers some of the warmer southern climes.

February 27, 1867: 64F at Lansing [incredibly the low was 14F] --> possibly erroneous, 1930 publication indicates high of 66F on 2/22 was 4F warmer than any other February day of record in East Lansing dating to 1863 [original data unavailable]

February 19, 1884: 64F at Detroit [tied]

February 4, 1890: 66F at Benton Harbor

February 21, 1930: 69F at Monroe

February 26, 1944: 70F at Monroe and Wayne

Not sure thereafter. Per climatologist Maximiliano Herrera, the state record prior to yesterday was 72F, although I'm not sure where or when that occurred. I thought maybe 2017, but the maximum was 70F at seven different stations on the 24th.

They stopped including these nifty little tables in the monthly and annual reviews, making it a bit difficult to identify state records without the source data.

Ah, here it is. I noticed DTW reached 70 in February 1999, so I figured that was it. Confirmed.

February 11, 1999: 72F, at Battle Creek

February 12, 1999: 72F, at Three Rivers and Holland

Today will likely set a new monthly maximum, as the record is 70 in 2017/1999.

 

Fun fact- the only month to not hit 70 is January. The warmest temperature is 67° on Jan 25, 1950, however many areas registered over 70 that day, including 72 at Ann Arbor. I suspect present day DTW would have as well. On the flip side, the only month not to have a temperature in the 30s is july, all time low being 42 on July 6, 1972. So theoretically, it is possible, though extremely unlikely, for someone in Southeast Michigan to be as cold as the 30s or as warm as the 70s any month of the year.

It has been as cold as 31F in East Lansing during July. On July 15, 1863, the high was 69F and low 31F. No maximum & minimum temperature records for southeast lower Michigan at that time, but likely was in the 30s.

More recently, and closer to southeast lower Michigan, the low was 40F on July 1, 1988 at Toledo. I would imagine some of the colder spots were in the upper 30s.

38F at Milan on 7/3/1988 & 39F at Hillsdale on 7/1/1988. State low that year was a chilly 28F at Kenton (western U.P.) on the 1st.

PIA set the all time February and winter record high AGAIN yesterday, with the temp plummeting 61F over the 14 hours. Insanity.

I chased yesterday and busted on the dryline, but was able to get a distant view of one of the tornadoes in the suburbs.

The temp drop with this one is pretty intense. I think it was in 2020 but I was down in STL in April. One day it got up to 92 and 28 hours later it was 26 with a snow shower as I went onto the back deck. Was really insane to experience

Looks like a solid 2nd place for DLH this winter, but still 3F cooler than 1877/78.

1877-1878 - 28.0

*2023-2024 - 25.1

1997-1998 - 22.4

1881-1882 - 22.0

1930-1931 - 21.5

MSP will have this one in the bag by 1F.

*2023-2024 - 30.0

1877-1878 - 28.9

1930-31/2001-02 - 26.8

2011-2012 - 26.2

1881-1882 - 26.0

And just a few miles down river at LaCrosse a solid 2nd about 2 1/2F cooler than 1877/78.

1877-1878 - 34.2

*2023-2024 - 31.6

1881-1882 - 29.6

2001-2002 - 29.2

1997-1998 - 28.8

 

Looks like MSP is a hotspot up this way in the our part of the sub. :)

Throwing in Marquette, MI record, shows similar. Should make a note here. MAR was 2400 readings until Jan 1979. Then went Co-op in May 1979 at 2100 readings. Then to 0800 readings in Aug 1996. Winter time adjustment would avg + 1-1.5F. That makes the avg DJF much closer in the rankings for this season, and 97-98/2001-02.

1877-1878 - 30.7

*2023-2024 - 29.1

1997-1998 - 28.4

2001-2002 - 27.4

1931-1932 - 27.1

 

Starting with 0800 time, MMTS was put in place, so a digital set up locks in the time, and auto resets I believe. When using Max/Min set up, observers would have to manually reset when they took readings, leaving the actual reading time a bit in flux as people are not robots.

Cold day here with am temps -sd's and currently running in the mid teens in the early pm. 0.1" of snow from the snow showers yesterday. Rapid warm up for the weekend with a chance of rain before temps go back to more avg early next week.

A lot of parallels to 1877-78 this winter, including the core of the most insane warm departures in the upper midwest. 1877-78 was very mild here too, but ranks as 15th warmest. Most of the other powerhouse warm winters of that era rank higher (1881-82, 1879-80, 1889-90).

Detroit will end up as the 4th warmest winter for 2023-24, but still a solid 2° colder than the grandaddy of winter warmth 1881-82.
