BlankA hard frost overnight with a minimum of -3,8°C and the temperture is
struggling to reach 4°C. The sky has virtually no cloud apart from afew
contrails and a small patch of Cirrus so despite the low temepratures it
is very pleasant outside.

I am slightly surprised to see Philip Eden's comment about the pressure
being the highest since Dec 2001 since I saw a pressure of 1041.7 hPa on
the the 12th Dec 2005,;the pressure today reached 1041.1hPa.

Alan ... I had 1041.3 this morning, and 1041.1 last Dec. Different sites,
of course, Luton and Whipsnade, but close enough to make no difference
in most instances, although my correction card may not be 100% reliable.
