These events are not necessarily my 'favourites', just the ones most memorable to me from before I started following weather more geekily.
Jan 2013 - struggling to get to school (which somehow stayed open most days) in the car because of the snow - other cars were literally abandoned on the side of the street. That cold/snowy spell doesn't seem to get the attention that some others do.
28th Feb-2nd March 2018 - recall it just getting colder and snowier day by day. On the 28th I was on the bus home late and worried if I'd get back in the snow, and on the 2nd I went to work through through the deep, settled snow in town. The weather stayed generally cool, cloudy and unsettled until mid-April pretty much, and then of course we had that very sunny May-July. A dramatic several months of weather.
16th Oct 2017 - ex-hurricane Ophelia turning the sky orange that morning was fascinating, I was at work and sat there in the office baffled.
Jan 2010 - I seem to recall this and the school closures more than December of the same year, for some reason. I think we just got so used to that sort of weather in the winter's months of 2010.
Winter 2014 - less specific memories of this, but obviously was aware of how notably wet it was and how the more rural parts of Somerset were being flooded. I think the snowlessness was also probably quite notable after the previous few winters.
