One final thing. Because your comment also talked about snow, which seems to be your biggest complaint. Keep in mind that it is warmer temperatures that produce more snow (not warm as in, above freezing, but 20 degrees is warmer than -20). Why? Because the warmer the air is, the more moisture it can hold. So, during a polar vortex, you probably wouldn't expect much snow. The reason you saw more snow in the past is because the temperatures were a bit warmer. However, you should still get plenty of snow on most years. Again, the primary reason for low amount of snow (and lots of rain) this past winter is because of El Nino, which repeats about every 15 years and lasts for a couple of years generally. There will probably be relatively less snow next winter too, but I highly suspect the following winter will produce lots of snow. Depending on your age, there was little snowfall when you were a kid for a couple of years because the last El Nino happened in 1997-1998. Go ahead and look it up. One of the lowest snowfalls on record for the state of Ohio. I looked up the data from Cleveland.com. So relax! In a couple of years you'll see plenty of snow!

One more thing. In your comment, you're basically saying "we don't get many cold snowy winters anymore". The data for the recent past (except for El Nino years), however, tells a far different story. And it's likely that future winters will be COLDER. As I'm sure you know, most of the world will experience warmer temperatures. Ironically, it's the warmer temperatures in the rest of the world that will likely result in colder temperatures in the Midwest/Ohio River Valley, (and also parts of Eurasia), because it is those warmer temperatures that destablize the polar vortex, which is why the polar vortex is now going further south instead of staying in Canada.

No offense, but I find it annoying when people complain and, in their complaining, show very little knowledge or understanding of the subject. Sorry if I'm sounding mean, I 'm not trying to. Your comment bothered me enough that I wrote out these responses. And I'm sure most would get annoyed when they think someone is complaining about something they know little about. Again, I'm not trying to be mean. I'm really not. We all make mistakes. My logic isn't always perfect. And if I'm making a mistake in my analysis now I'll gladly apologize and admit my foolishness. I'm simply trying to improve your understanding. I hope it motivates you to study the issue further. Here's a good article to start. Well, I would embed the link but it won't allow me to. So google search "Weakening polar vortex may yield longer, harsher winters in North America" and you'll find the article easy enough. That's the title of it.

Slight edit from above comment. "And while not the Ohio Valley, the same polar vortex resulting in temperatures that were COLDER THAN THE SURFACE OF MARS." should be "And while not the Ohio Valley, the same polar vortex produced temperatures that were COLDER THAN THE SURFACE OF MARS in the Chicago area".

Response to Johm

I live in the Ohio Valley too (extreme portion of Southern Illinois, in Alexander County). While this winter was mild, you do realize we had one of the coldest winters ever a couple of years ago right? When the polar vortex swooped down. Did it two years in a row if I remember right. And while not the Ohio Valley, the same polar vortex resulting in temperatures that were COLDER THAN THE SURFACE OF MARS. And we've had a lot of ice storms during winters here. Sometimes looks like a level in Super Mario for a minute there. I think something like 5 or 7 years ago we had so much ice on the trees that the weight of it downed a few trees in our yard and just about all of them had several branches fall. Don't get me wrong, pretty much everywhere else in the world is experiencing warmer temperatures from anthropogenic forcing but, it's likely that a good portion of the Midwest (including the Ohio River Valley) will experience colder temperatures as the polar vortex becomes increasingly unstable with more extreme fluctuations as a result of climate change. The warm/wet winter we had this year was largely a factor of El Nino. I realize that I'm a bit further west of your location but Ohio should experience the same general trend.

Jasper, Ohio Mild temps all winter little snow, a lot of rain

I miss the winters from my youth

I live in the Ohio Valley. Right around the Steubenville, Toronto, and East Liverpool area. I remember when I was younger there were winters in where you wouldn't see grass for months. From late November until February or so. I remember going outside and having to dig paths to out driveway. The snow would be a foot or more deep. I remember getting massive snows. We're talking like four foot or more. I miss those days. Winter this year has been terrible. I don't think we have had 6" all winter total. It's been a rainy drab winter. I am so sick of the rain. My thing is...if its winter time I'd rather have the snow vs the rain. It looks like our good winters are just a memory now. Hopefully we get something in March. Historically and statistically we have been getting most of our better shows in March. I can only hope. I am one of the few people that actually likes living in this area because of the winters. When everyone else is complaining about the snow, I am cheering it on.
