Minimum MSLP 967.9 mbar here (at 0538). This is just below the 968.4

the lowest in January since 1949 (when, at 15 h on 1 Jan 1949, the
barometer stood at 963.8 mbar at Heathrow).

968.1mbar at Hampstead at 0555 and 0600; estimated (from
barograph) 969.8mbar here at Whipsnade around 0600.

It seems that my 966.6 is a low value suggesting I may need to recalibrate
the offset. However the Teddington NPL value looks to be very close to
966mbar (+-0.3) so I am not sure how far out my value is and I need to
look
at the deviation at the other end before taking any action.

20 miles to the east of you I had 966.4mb at 0610 this morning on the Davis
AWS. EGLC and EGSS both had 966mb at that time. Mind you I recorded 961.7mb
1535 on 10/3/08.

All the best
