.... or anyone with expertise on rainfall radar.

This evening it rained hard (and I mean, hard) in
Romsey. The total duration of the shower was
70 minutes (1850-2000Z) and dropped 8.2mm
of rain. The cloud responsible developed and
decayed overhead.

Looking at the rainfall radar picture from the Met
Office website, I was astonished to see nothing in
my area, not a single pixel. Jon, do you have
rainfall radar of finer resolution that might have
picked up this downpour? Would I be right in
thinking that very localised rain may not register,
no matter how intense the ppn?

Cheers,

Nigel
