Cold last week of February and first week of March in central England
According to results that I've generated, the mean CET for the period 21st February to the 7th of March was -2.2°C, that 's -6.6°C below the long-term average (1961-1990). That's a clear 1.4°C colder than 1786 the next coldest such like period. Even if we do have a couple of ice days in this coming week I can't see how the mean temperature can get close to those of 1947, although it might push the means for 2005 and 2006.
