Martin, I am also at 80m, but have higher ground to the S & SW (as I
am on the northern side of the North Downs) - are you in a flat area?
just wondered if there was any other reason why you have more rain!

5.8mm here so far today.

... we are pretty flat; no orographic reason that I can bring to mind to
explain a difference - more likely a function of the variability in the
(diffuse) frontal zone which is evident in the radarnet imagery: the
green/yellow "blobs" have been biased more towards us ;-)

Martin.

8.9 mm in Chalfont St Giles up to 0900z and a further 2.5 mm to 1300z.
Probably a slight bit of orographic enhancement due to the proximity of
the Chiltern Hills.
