Some memorable cold spells here:
February 1991: Very cold with the reservoirs freezing over. Some snow later.
February 1996: It snowed for some 18 hours giving around a foot. A prolonged cold frosty period followed which delivered some impressive minimums and the snow barely thawed.
November 2005: The snowiest November for a long time. An unexpected 4-5 inches overnight and then some cold frosty weather.
February 2007: A generally rubbish winter but two heavy snowfalls in 2 days, the last of which was completely unforecast and gave around 8 inches. Memorable just for that.
December 2008: No snow but one of the most impressive anticyclonic frosty periods I've seen. Streams and lakes froze over.
February 2009: Heavy prolonged snow showers from an easterly... here?! Then we had several battle ground snow events which gave a few inches each time. Great spell. Impressive cold and frosts too.
December 2009 Very cold and 3-4 inches of snow from a northerly late December.
January 2010: 4-5 inches fell overnight early in the month. Then later in the month a battleground snow event that gave 7-8 inches of snow. Impressive cold also.
Mid November-December 2010: Exceptional period of sustained cold. A streamer from a northerly in mid-December gave 8-9 inches overnight which remained essentially unthawed until the last few days of the month.
January 2013: A slider gave arond 8 inches of snow. Two more lesser snow events gave another 4 inches. About a week of ice days resulted in no thaw whatsoever.
Probably the most memorable of all was February 1996 and December 2010. This current spell suffice to say is not to fit lick any of the above's boots.
