Can anyone remind me please: Is there a rainfall radar history freely
available anywhere? Specifically I'm interested in yesterday (8th July) for
East Anglia and the period 1900-2000 BST.

A very localised thunderstorm went through and the AWS record we run at CB6
1RA (Littleport, East Cambs) shows ca 48mm falling in about 45
minutes(1910 - 1955 BST) plus a little more either side of the peak (max
rain rate of 256mm/hr). This is pretty unusual for these parts and really
was the proverbial month's rain in 45 minutes!

AWS was a Davis Vue at 3m height but relatively calm (max gust of 11mph at
the peak rain rate) and is just a unit we use for general wireless testing
so not been recently checked or calibrated, but nothing about the record to
suggest it's seriously in error. Another AWS about 500m East recorded 35mm
in the same storm, so I know it's approximately right. Taking the rainfall
total at face value, this would almost certainly have been an underestimate
because of the tipping spoon under-recording at the peak rain rate. It was
localised - another AWS we run 5 miles or so SW saw only 13mm and a second
AWS 5 miles SE saw just 2mm.
