Think your right. It's taking a bit longer. 

I also wonder if it has to do with how dry it has been.  Not getting all that additional frozen precip falling into the lakes.  Kinda like a glass of water cools faster with ice being added than just sitting in a cold room.

Thought about that later. Really hasn't been much snow hitting the Lake up here. You do get light stuff from the LES that helps, but synoptic help is a plus as it's much more widespread.

By the time Friday comes, it will already be halfway through the month with literally no snowfall for the month so far. Just had the least snowiest February ever back in 2023 with only 0.1" for that February. #FebruarytoForget

Suicide weather today. It's going to be that kind of week. Certainly a crappy weekend upcoming following Valentine's Day.

Certainly a brutal start to February for Dayton. Since 1894, I could find only 5 years without at least some snowflakes flying in the first 10 days of the month.

Meanwhile, it has been 4,429 days since the last calendar day snowfall of 6.2" or more at Dayton. At this point, I'm unsure whether Dayton will see a daily snowfall that high ever again. I initially believed this to be a record; however, I noticed xMacis culminates streaks at days with missing data. Allowing for missing days, two potentially longer stretches arise. Of course, one would have to examine those streaks to see whether the missing data is impacted the longevity.

The last time Dayton saw a snowfall that high was Boxing Day of 2012. That's a long time!

That full run of the 12Z Euro to finish the month is ridiculously cruel. I'm not even going to post an image of such cruelty

Significant cold this morning. I-Falls -33 (5th), Hibbing -36 (2nd), Duluth -26 (4th), Brainerd -29 (t4th), Park Rapids -29 (t5th), St. Cloud -19 (t5th), and Ashland, WI -18 (t6th). And it's not unusual for NWS DLH to undercast a.m. temps as you'll notice from yesterdays story board.

YHM was at 13.2" yesterday. My backyard was just above 14" 

This storm will end up being 4-8" for us 

I was doing some more research on Toronto seasonal snowfall. Look at these historic winter snow totals from the 19th century. Those are some "old-fashioned" winters!

image.png.913ecbc2a2afac23b6ed9132bdb78e5c.png

March 1870 must have been insane - wow! 62.4 inches of snow, with a 26.8F mean temperature. 21.5" of snow from the 15th to 17th, and 20" from the 26th to 28th.

I wish there was more detailed records of some of these historic winters in the 1800s. Nothing has ever come close to how snowy some of them were. And I'm not sure why? Not sure if theres stations in Michigan, Ohio, or Illinois that go back that far?

Even from a temperature standpoint and not just in winter, but yearly. Not sure if its a result of UHI, but a lot of the summers in the 1800s in Toronto were cold by today's standards only averaging around 68 (+/- 1.5). 

However, some of the numbers at YYZ are questionable for some winters especially 07-08. Every station in Toronto recorded 90-100" that winter with YYZ only at 76". Consequently YYZ fell short by 5" from breaking the all-time record (1938-39). Similar story with 08-09. YYZ recorded 60" but most stations were 70+".

Since today's system significantly underperformed compared to how it was looking a few days ago futility is still technically on the table for MLI.  So far today they've officially picked up only an inch.  Will probably end up with <3" for the storm total, which will keep seasonal total <6.5".  With the way things are going the Fri-Sat system will find a way to miss or underperform.  After that who knows how things go.

Its been consistently cold here for a long time, typically <-4C/15F. Getting fewer peeks of sun recently so grumbling about that one. We got surprise snows on and off all last weekend which bumped totals even further. With the 15cm I got from this mediocre snowfall, I'll receive more from les today all the way til Tues! WUN has me for 9cm sat sun mon while twn just 5cm each day with 10-15 on Sun's system. TWN 14-day for entertainment shows snow of some form every day til Feb 23!! Solid snowy winter.

I'd like to see more data of March 1843. That month was colder than like >90% of Jans and virtually every Feb and Dec from what I gather, which seems almost impossible, but apparently it really was THAT cold.

There is some sparse data and journals and stuff that you can piece together what type of winter it was, but certainly not enough to get accurate or even semi-accurate precip/snow/temp data.

I have studied it when I have spare time (often in the weather "off season" of summer lol) and have a document that I jot notes down, plus theres David Ludlum books that details things. But im nowhere NEAR done studying them. Honestly, it appears that the overall jist of winter over here (Detroit) was very similar to it is now, although a likely colder climate overall. Some winters were harsh and others were not. The 1830s to mid 1850s seemed to be dominated by mild, dry, "open" winters, though with exceptions of course (a HUGE exception being 1842-43). Then the mid 1850s to 1860s seemed to have a lot of harsh winters, tho again, with some exceptions.

Notes of "easy" winters:

1846-47 (wheat crops destroyed due to open winter)
1847-48 (small quantity of snow fell, open winter; wheat damaged)
1849-50 (quite mild and snowless; only 1 day of sleighing as of Jan 28)
1852-53 (open winter, very dry)
1858-59 (crops likely damaged due to open winter)
1859-60 (wheat damaged somewhat due to open winter)
1860-61 (no ice on any river on any account, open winter)

 

Notes of "severe" winters

1842-43 (most severe winter ever known; snowcover nov 17-apr 8)
1854-55 (open winter until deep snow late Jan, then it got the deepest since 1842-43)
1856-57 (houses suffered the rigors of the severe winter)

I thought I would contribute with the data I have. Take it for what it's worth, but 1850 forward is a pretty solid avg, with pre 1850 in need of more datasets to make it better. Because your on the eastern edge of the zones I have, I've also included the NE data so you can get a better feel. Just as side note, the 1830's were more avg to above for winter in both sections.
