Both of the last two October's have seen snow in Aberdeen. I think 2012 did too.
As for September snow my Dad definitely recalls snow during one of the harvests of his childhood so must've been some point in the 50s.
No snow in the last two Octobers here both of which were composed of the cloudy, mild crud that has prevailed in October this century. Last year especially was hideous.
2008, 2010 and 2012 all had snow lying but I haven't even so much as recorded a frost since and only 11 single figure maxes in the past five Octobers compared to 13 during October 2012 alone. 8 of the 11 single figure maxes I recorded were between 9.4C and 9.9C with only the max of 6.3C on 30th October last year below 8C. Cold in October is certainly long overdue.
Sleet fell on 29th September 1954 and the snow we had at the beginning of October 1994 was the earliest wintry precipitation since then.
