Detroit city temps are absolute fake garbage. I have told you many times, many non-first order stations have calibration issues that are left unattended. They arent the importance of a first order station (like DTW). The Detroit city thermometer has ran a little warm for a while, but it went bonkers in a week or two ago, running some 5-6F too high. DTX finally had the thermometer fixed a few ago per the coop leader.

The avg temp, which obviously is the main metric, ranks as a 2-way tie for 40th warmest year to date (Jan 1-Apr 24), so 39 years were warmer and 111 colder. The avg high temp ranks as a 3-way tie for 25th warmest, and the avg low ranks as a 4-way tie for 58th warmest. Obviously, this is entirely due to March/April (mostly March). I am not a fan of doing random rankings on a given day, its better to let each month play out. Jan-Feb ranked as a 2-way tie for 54th coldest at Detroit, meaning 53 years were colder & 97 years were warmer. The highs were a tie for 58th coldest & lows a tie for 53rd coldest.

Trees rapidly flowering after the warm days off and on the past week.

Even in our country, a mere speck on the globe, patterns are absolutely not the same from one place to another. I do not agree with bluewaves generalizations simply because you cannot predict the future, period. As he is familiar with NYC more than I am, Im not going to go into detail about anything, but i feel some of these assertions as about low snow winters of the past vs low snow winters today, or why there was heavy snow last decade, etc etc are a bit of a stretch. The coldest period of NYC's climate record would still be a super mild winter by todays standards in Detroit, and again, look on a globe and see how close the two are. NYC is not going from some winter paradise to the tropics. I also feel that the feast/famine approach has always applied to the east coast, even if its more extreme now. But its interesting to see that you are seeing that more in new england as well, as I have not really seen that here, and our temperatures are likely quite similar. Despite all the microclimates and nuances, I stand by the fact that from a pure snowfall perspective, anyone north of 40N is sitting pretty in a climate when winter precipitation on average is increasing yet it is still plenty cold for months to see fun snow times.

Thats insane. Whats funny is id heard several of the normies refer to this as an "old fashioned" winter. lmao, yet snowfall was way below avg, but give them a cold, white Jan & Feb with ice covered lakes and it does the trick I guess. Meanwhile, 2 years ago we saw 8" more snow than this season but we heard what a mild winter it was, and I also heard multiple times in some heavier snow winters that finished well above avg that this was a "normal" MI winter. Ive learned over the years that the general public base their general opinion of a winter (here at least) off of how cold and snowcovered Jan/Feb are. Doesnt matter how much (or how little) snow falls in Oct-Dec or Mar-May. And Ive learned that the general consensus of snow weenies is all about that final snowfall number, regardless how the winter was overall. (Again, these generalizations dont apply to all).

That 7 year "snow drought" talk is very over the top IMO. Its a simple regression to get closer to the mean. Its been happening since the beginning of climate records, and its how averages come to be. I looked at a few places. For starters, it looks like only NYC is the one who can claim their all-time low for the past 7 years, not the entire region. And for what thats worth, there were other 7 year periods closer to this 7-year low (1920s & 1950s) than any were to the 7-year high from 2010-16. But the bigger picture is that I just dont understand how the anomalously high number of heavy snow winters in the 2000s and 2010s are just dismissed as if they never happened when discussing recent low snow years. I mean, we arent talking generations ago, and we arent talking slightly above avg snowfall. We are talking very recent years that we ALL remember and that set one heavy snow record after another.

I personally already like the look for next winter for the simple fact that the worst case scenario for winter here (strong El Nino) appears to be the least likely scenario for 2025-26. Multiple other things going in our favor too, but not going to get into details this early. Also, a reminder to all that there is a 2025-26 discussion thread.

Youre looking at just a small sample of La Nina years though. Youd really want to look at the entire mean of them and see if any trends have occurred/changed along the way. Several of those winters were actually quite dry here, which strays from the typical la nina mean.

Since the April 10th snowfall, the forecast wet, active, and potentially severe period of weather has produced a grand total of 0.02" rain at DTW

Every year on this date I always remember this snowfall on April 20/21, 2021. Hate late spring snow all you want, but the scenes were beyond stunning, an absolute nature masterpiece. It was the perfect storm. The spring greenup was ahead of schedule, then snow began the afternoon of April 20th and snowed all night until the early morning hours of April 21st. Temps fell to 32F for most of the snowfall, but as the snow ended towards sunrise, skies immediately cleared and temps fell to 29-30F for several hours before the late April sun did its thing. It created some surreal scenes. DTW saw 3.5" of snow, I saw 4.4", Monroe had 5.7" and Toledo had 5.0"

Thanks! No noticeable trends here, quite a variable dataset

Do you have a list of years that were cold neutral following la nina?

With yesterday's warmth and the flowers on my maple starting to emerge, I wanted to see how much they would open in one day. You can really see the difference.

DTW hit 83 yesterday. Most of SE MI topped out between 80-83 (the faulty warm sensor at detroit city airport hit 88, but it's literally running 5-6° too warm, a tcc dream). In the past 2 weeks, southeast Michigan has seen temps from the 10s to the 80s, 1-2" of snow and a tornado.

Yeah we had lots of T depth days too. Jan-Feb basically had no totally "bare" ground. T-1" is better than 0 imo. As you said, looks like winter. And very wise words from your father!
