I'd personally be very hesitant to use a 10-year trend as the basis for anything you'd want to confirm (or deny) a theory applicable to hundreds or thousands of years.
But - that noted - the trends here that I have noticed:
In the non-mountainous parts of North Carolina, you could generally count on 1 or 2 good, deep snows every winter. We haven't had a major snowstorm (more than 3 or so inches) since 2002; 8 years without that is pretty much unprecedented.
Spring is traditionally the stormiest and wettest time of year; fall is traditionally dry. Autumn seems to have gotten a little soggier here, and spring - for the last 3 or 4 in a row at least - have been about normal temp-wise, but far, far drier than normal.
I don't know if it really means anything; it may be normal cycles, or not. The 1980s and 90s were very stormy, compared to the decade before and after: several unusually snowy or unusually cold winters in the 80s, 3 very atypically violent tornado outbreaks (one of which was of a magnitude nothing like anything witnessed here during recorded history), followed by the Hugo-through-Floyd 10 year series of hurricanes. The 60s, 70s and this most recent decade were all very placid in comparison.
Just look at what the sun is doing, as well as volcanoes around the world. That's 90% of the weather and climate influences. but anyway, it is legal to pelt Al Gore with snowballs.
The only obvious thing in the last few years or so is that August and December have become noticeably colder. In the last 8 years December has become the coldest month of the year and August is nearly as cold as June because all the last 10 Augusts have been worse than the 1981-2010 average (for either temps, rain or sun) which seems a very strange thing statistically.
Large snowstorms have by some accounts become more frequent. A change I certainly approve of! I remember my high school principal (big AGW proponent - made us all watch Al Gore's movie in the HS auditorium one half-day before winter break one year) making an offhand comment, when talking about snow days, something to the effect of, "but that doesn't really happen anymore." Well, since that time we've had our top 2 snowiest winters on record, and countless large snowstorms.
Months in England since 2000 in Top 5 Warmest and Top 5 Coldest in past 100 years (our records go back a lot longer, but it's perhaps not a fair comparison to measure today against the Little Ice Age):

Those two cold months were the absolute coldest in the past 100 years, but otherwise the warming trend is pretty clear, particularly in autumn. If I had used 1990 as my starting point then the difference between the number of warm months and cold months would be even more stark. The two warmest years in the past century have both happened since 2000 (and the two below those happened in the 1990s) whereas no year in the same period has made it into the bottom five.
Nothing particularly noticeable. 2011 was an exceptionally warm year but had an abysmal cool summer so nobody really remembers it. Only autumn was noticeably mild. Snow still occurs every year. January 2013 proves that it doesn't need to be very cold for it to snow a lot.
The heat wave of March 2012 was freaky. The record high in Moncton in March until this time was 18.9C but on March 22 we reached 26C, I remember thinking that something isn't right here. Off course since then we had paid for this in following winters especially the winter just past.
It just seems that there are more and more extremes winters and summers are either way above normal or way below normal, more and more decades old records are getting broken. I've seen reports that the jet stream is getting "stuck" more often, I think that this is significant.
