Highest synop pressures I can find today [Thursday 10th] are (mbar):

1040.7 Malin Head 03980 15z - also 1040.5 14z, 18z
1040.5 Belmullet 03976 13, 14, 15z
1040.4 Connaught 03973 11z, 12z, 18z
1040.3 Claremorris 03970 11z

September British Isles records still stands - just - 1041.2 mbar at
Shawbury, Shropshire, 00 and 01 GMT 19 Sept 1986.


... Stephen will no doubt come in when he can, but it looks as if the
September record was broken last night at Ballykelly (03908) at 11/0050Z
... however, it'll need to be 'buddy checked' and also internally checked
[i.e. to see if earlier readings were 'sensible' within the overall
pattern & within the station's own record: Stephen's the expert on all
this so I say no more :-) ]

[courtesy of OgiMet: look for the '4' groups for those that don't know the
code; thus in 03908, the group 40420 indicates a mslp of 1042.0; the group
immediately preceding it ('3' group) is the station level pressure.]

There was a 1042.0 also at 00z at Tulloch Bridge (03047), though
that, too, looks a little high. Altitude correction is relatively large
there as well.
