Looks like MSLP 1000 hPa here in Bracknell since about 21Z 15 Feb
2010, maybe until early on 1 Mar. It would be interesting to know
when this last occurred in the south of England. Very few longer than
about 6 days back to 2003. I would guess about once per decade. It's
an artificial limit, but has some merit, I think. Alas, I can no
longer run my Met Office sequences program on Heathrow hourly data
from 1949!
My lowest pressure since 2003 is 962 hPa (possibly 963) at 15Z 10
Mar 2008, so next Sunday's low has that to beat.

.... latest UKMO NAE 06Z has the low below 962 hPa near Belle Isle
(north sea area Biscay) at T+45 (VT 0300GMT/Sunday morning), with the
low heading across Brittany and Normandy etc., thereafter; looks as if
any pressure records might be safe on *this* side of the Channel
[might be of interest taking the system as a whole though] - the
gradient in the SW quadrant look fierce-some, though with a decent
curvature. Still, MeteoFrance will be twitching no doubt.

Good spot! I'm highly confident that sequence will end next week.
