Has anyone lived in a place (or know of such a place) where in at least one year it seemed like the transition from summer to winter was nearly instantaneous? (I suppose it could go the other way around, but that seems less likely). That is, there was an extended "Indian Summer" which was abruptly followed by a cold snap that hung around long enough that by the time the weather reverted to the long-term average, it was clearly winter. (It's not just a warm day followed by a cold day, it had to have been consistently warm before and consistently cold afterwards).
I'm guessing the Midwestern US has a number of plausible candidates for this. If you know of a good candidate, it would be nice if you could find a graph, too. I'm particularly interested if there are one-day stark transitions, e.g. the daily high had never been below (say) 20C since the start of summer, then one day fell immediately below (say) 10C and then never rose over 10C again until spring. I don't know if that's possible, though.
Some other candidates may include places in central-southern Siberia (eg, Ulan Bator, Irkutsk, Novosibirsk, etc) and central Canada and interior Alaska (eg, Winnipeg, Yellowknife, Saskatoon, Bettles, etc)

I know those climates have very quick transitions, but I'm not so much looking for climates, but specific weather in a given year, in which there was an unusually discrete shift in weather, rather than the more continuous shifts that are generally the case.
It could in fact involve temperature changes less drastic than those, but are more unusual for said area's climate. For instance, in 2013 I distinctly remember it being consistently unseasonably warm here at the end of March, probably mid-20s C, then the very next day it fell into the mid-teens and never went back (except for brief periods, due to foehn winds) until spring.
WeatherSpark refers to "warm spells" and "cold spells" as days with above and below average high and low temperatures, respectively. What I'm looking for is more like a significant warm spell that immediately precedes a significant cold spell in the autumn. There is a reasonable example of the winter -> summer variety in the Urumbqi link. Feb 25 -> March 29 had 33 days of below average lows, while April 9 -> 28 had 20 days of above average highs. It would have seemed like winter went very quickly to summer from mid-March to Mid-April, although it's not quite as clean an example as I'd like.
Not exactly what u were talking about, but in Perth this year, we had a long, normal spring and then on the 15th or 16th of Decemeber we got a 38˚C day and now it's been averaging 32-35˚C since then. So an immediate change from spring to summer rather than winter to summer if that's any help, just look weatherspark or something like that for info.
Pretty much every day in New England. One morning, it's in the negatives (F) and snowing, then later that day it'll be in the high 60's (F) and sunny. Weather here is all over the place.

What I'm looking for is a one-off sudden change as opposed to consistently erratic weather, like 10 days of unseasonably warm weather followed by 10 days of unseasonably cold weather, the result being that the change into winter could be easily marked by one day.
Last November in west central Texas it was 80 and sunny one day, and the next had lows in the 30s and highs in the 40s and the day after that got down to the 20s.
