Northeast Ohio and Northwest Pennsylvania. My memory is well supported by data. Erie lakeshore used to be freezing cold deep into May. A linear regression shows an increase in May high temperatures of nearly 3.5F since 1990, which is a lot more than the Coastal Plain. It's gone from several degrees colder than New York City to only a couple of degrees colder.

May high temperatures have barely budged at New York City over the same time period.

oh being close to the lake is what most influences your temps

the funny thing is over here amount of sunshine is what defines heat for me, my body cools a lot at night, regardless of temps.

Lonely times?

lol probably!

seriously, though, after midnight it always seems a lot cooler.

I'm surprised that you didn't jump on that 1970-now warming image, since the 1970s were one of the coldest decades

Oh, but you mustve missed this:

Chicago (and Cleveland) lakeshore would have more of a difference year-round than Detroit. Its my understanding the entire reason the NWS (or formerly Weather Bureau) moved stations is for more uniformity due to increasing influences at a station site. DTW airport absolutely has seen increasing UHI since the 1980s due to so much expanding concrete. They were a radiational cooling magnet in the 1960s-70s and that changed drastically starting in the 1990s. Detroit city airport is no longer a first-order station, but it does have a thermometer so to compare, the first 20 years DTW became the official site, DTW averaged 1.7F cooler than DET. The last 20 years DTW has averaged just 0.3F cooler.

Regardless of the site locations, we dont know all the warming influences (or lackthereof) at any given time. There is no way a big city full of dirt roads in the 1870s would have the same temperature readings as that same spot would have as a concrete jungle in the 2020s. 

That chart, "since 1970". THAT has also been discussed multiple times now. This unusual starting date is used frequently, and it is soley to make warming look as extreme as possible. Starting a chart in 1970 ahead of the coldest winters on record will give you the biggest regression line. And as we move farther away from 1970, why cling onto using that starting point? Its now 55 years, so far more than the 30-year periods commonly used, that you wonder why not go longterm? Its because to do that, youd have to include the much milder winters of the 1930s-1950s which would really tone down that regression line. So youd have to go back to 1870 to make it a bit better. You will never, EVER see a regression line chart start in 1930. And whats funny is that that would make a lot more sense than 1970 as we are nearing the 100-year mark. Yes Ann Arbor winters have warmed 3.9F since 1970....and theyve warmed 1.4F since 1930. 

Regardless of the amount of warming or any discussion on temps, site changes, etc...the lower Great Lakes are not seeing any notable adjustments to their snowfall or snowcover climo other than normal decade to decade noise, although erring on the side of INCREASING somewhat rather than decreasing. So this brings me back to my original point, how is it that suddenly NYC is seeing this erratic rubber band from snowiest decade on record to a snow drought from which they supposedly may never recover?

Really though, it gets tiresome so I limit myself in these discussions. If you are discussing a cold and or snowy aspect of the weather that doesnt follow a straight warmer/less snowy path, you often get a lecture on some unrelated aspect of CC. Im not debating the warming of the earth. I will be 42 Thursday and my mom is 67 (a good weather memory)....there is nothing drastically different about our weather/seasons now than at any point in our lives here in Michigan. I was questioning Bluewaves talking points because, intentional or not, they come across as to where someone my age living in NYC would have now experienced both the snowiest decade and the biggest snow drought of the entire climate record, with the snow drought currently at the point of no return barring some miracle. Its like a slideshow of different climates in a 20-year span after remaining rather steady the previous 150 years in one spot. Just seemed off to me.

The climate models were wrong, they actually predicted an average of 3 100 degrees annually for NYC by 2045 and I just don't see that happening.

The models have been and will be wrong about a lot of things. The outlandish predictions of how much 90F+ (and 100F+) days will increase in northern locations has been a massive fail.

it must be a regional thing,  1980, 1983, 1988, 1991, 1993, 1995, 1999 and 2002 were our hottest summers in terms of 90 degree temps. 2010 has been our hottest summer since then.

My memory of the 1990s is that summers were about the same, springs/falls were cooler, and winters were milder and less snowy than the 21st century. Without a doubt the most sour aspect of the 1990s for me was winters.

Where was this?  Being a kid in the 80s, I "remembered" having lots of snow too.  Turns out the 80s kind of sucked for snow where I am.  

Its very odd to pick one random day. I guess I could say I remember as a kid it was spring by mid-late April and now we almost always get a snowfall. Its a huge generalization. July 4th is a hot summer day most of the time. If a cold front happens upon the area in that timeframe, so be it. But to assert that you would wear a hoodie as a kid and now its always 70+ is a stretch. Pittsburgh was 100F on July 4, 1911. The warmest July 4th low at Pittsburgh airport was actually 74F in 1999.

This is why winter is warming faster than summer and nights are warming faster than days. The fastest rate of GW is occuring in instances of radiational cooling during the winter.

Not only that, I think the extra moisture in the air is what keeps the Arctic warmer during the cold season. Even a small amount of moisture added to very cold air will raise the temp. Arctic summers aren’t warming much but as soon as October comes around, it’s always a torch(relative to average) in the Arctic. The moisture probably isn’t allowing it to cool off as fast as it used to. Then you have less sea ice which just adds even more moisture to the air. 
 

  In the Summer, the added moisture results in cloudier and cooler temps overall in the Arctic which is why we haven’t had a new record low in sea ice since 2012. You need warmer and sunnier temps to really melt the ice up there.

The average July low is up like 3-5F at all of the airports nearest me since 1990. Like here's a more distant suburb of Pittsburgh in 1988. The low was 35, 32 & 36 on July 1-3, 1988. Does anyone think such temperatures are possible today? The only place where such lows can occur today are places like Canaan Valley, West Virginia, which is an elevated (3-4k) frost bowl. Like this is supposed to be the Hottest Summer Ever (TM) and the average low at this location was a cool 55.7F. That's open window weather. Even on the days of 100F, it cooled down into the 50s and low 60s, enabling efficient cooling by a window fan at night.

Any other years that you want to cherry pick out that were very cold?  How many were warm and everyone was wearing shorts, probably most of them I would imagine.  And yes, if it got that cold again, it would be maybe 35 instead of 32 and still be a top cold spell.  You're too dramatic.

Hes excellent at cherry picking the most random things from xmacis. A random coop station in a middle of nowhere town with a population under 2K that is full of missing data and hasnt reported since 1988. If that isnt accuracy, I dont know what is.
