Of course there's going to be record snowfalls if the record only goes back a very short time. Same thing with record high temperatures and record low temperatures.
They are meaningless.
I wouldn't call them meaningless ... but, yeah, these records get broken all the time ... no reason to tie knots in your knickers ...
This is only a record for that date, October 20th, and there's only been 100 Oct 20ths in the past 100 years ... so a fairly small sample pool, we must take care to attach too much emphasis to the data ... also, the article says this is NOT a record for the month of October ... which means the meteorological conditions that produced this snowfall amount are known to occur, just "random" chance it happen to occur on October 20th rather than October 26th (or wharever) ...
Consider this:
There are about 6,000 weather stations around the world ... each one will have an extreme high temp, and extreme low temp and an extreme precipitation amount ... three extremes times 6,000 gives us 18,000 possible extreme events
per day ... for a "hundred year" event (or a 1% chance of occurring), we should
average 180 events per day worldwide ... so if this was an average day, there will be 179 other extreme weather reports to be had ...
This data is useful for planning purposes ... if we want to build a factory, and check the climate records ... we might see it rained 42" one day back 45 years ago, so we better make sure our factory can deal with that ... because it will rain 42" again someday, perhaps more ...
Warmer surface temperatures will most definitely allow more water vapor into the atmosphere ... roughly 7% per ºC at usual surface temperatures ... and what goes up must come down, as rain ... and there's every reason to believe considering Arctic Amplification this rainfall will be more widespread and less likely to cause flooding events ... and with a little bit of temperature rise we should only expect floods to be a little less likely ...
