Now it seems that the current severe spell of weather will soon ease, at
least for a time (depending on which model output you believe), I had a look back through my records. At the current site they only date back to 1980, so the severe winters of the 1970s and before are not included. The month-long severe spells we had this month and last winter either side of the New Year are the worst in my records since 1987. This year and last year have been of similar severity here. We have had a few more days of snow lying this year, but December 2009 saw the freezing rain episode which trapped us in Ashurst and January 2010 had stronger winds here making for a very penetrating frost which caused more burst pipes and freezing up of our boiler exhaust pipe. But it is still noticeable that, unless the cold air returns in depth and strength, the last two winters are still not in the league of the 1980s. In reverse time order... 1987 had a spell of bitter NE winds in January, giving a spell of 9 days in which the temperature only once climbed above freezing. Air from Russia gave me the lowest recorded *maximum* temperature in my records (-6.7C) and there are two consecutive observations with winds force 3 NE and air temperatures -10C. We have had nothing even remotely approaching this cold in the last two years. Then a late severe spell in March 1987 saw the current snow depth record set (18cm) - the maximum we have had this time round was "only" 12cm with nothing like this last winter (2009/10). 1985 was a prolonged affair with a total of 21 "snow lying" days - the most for any year in my 31 year record - spanning January, February and March with episodes of severe weather in all these months. The most severe was in February with 10 consecutive "snow lying" days (the current spell is a couple of days shy of this) and bitter easterly winds towards the end of this saw "sea" ice piled up on the banks of the Test just below the railway viaduct over it at Redbridge, with the brackish water freezing at certain states of the tide. 1982 saw a brief but very severe cold spell in January. Freezing rain followed by snow left about 15cm of cover, then Russian air was brought over. Skies cleared and the winds fell light to allow the temperature to drop to -14C overnight on 14 January - still my extreme low temperature record and this is lowland England only about 10 miles from the Channel coast. So far the only record either of the last two winters has broken is number of snow lying days in a month - two spells of 5 days then 7 days (and possibly still counting) beating the previous record of 10 days in a month in February 1985 and January 1982. But these two events were 10 unbroken days of cover while this month had two shorter spells broken by a thaw. So not a truly historic winter here - yet (if Will is to be believed). But it apparently has been elsewhere - how has it been for you? For reference, I am in Ashurst, on the edge of the New Forest, about 20m above sea level. [P.S. Unlike now I had an outdoor job in all the 1980s winters mentioned above - so I had to take it like a man! At least now I can watch it out the window.] -- - Yokel - Yokel posts via a spam-trap account which is not read |

![]() So not a truly historic winter here - yet (if Will is to be believed). But it apparently has been elsewhere - how has it been for you? Well the coldest December on record here (1960-2010) was 1981 with a mean of -0.5c December 2010 stands at a staggering -1.8c, after 24 days. Only January 1963 and February 1986 were colder since 1960, so I would say historic at the moment! Only downside is far less snow that December 1981, with just 21 cms total depth. December 1981 produced almost 60 cms, so no chance of getting even close to that ![]() Graham (North Staffs) |
