.... 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

Have a look on www.meteox.com - you should be able to zoom into your local
area and display the radar for that time. Shows showers along the south
coast at 1930 CET (1830 BST).

I drove through this line this evening: I left Bedford at 2015 and
when I got to Milton Keynes some few miles west, it was tipping it
down. Got to Tesco at Buckingham for fuel and it was virtually dry
though just started to rain as I left. Bicester was dry and nothing
down the A34,A303 and salisbury. ( A good run which took the predicted
3hrs 10mins to Dorset just west of Blandford - enlivened by a police
helicopter hovering c 200ft above BForum looking for someone with an
incredibly powerful spotlight)
I heard on Radio Solent that traffic was stopped on the M3 Surrey way
by the intensity of the rain

No precipitation whatsoever is indicated for or near Romsey on the
large AVbrief images for the times mentioned by Nigel. Not a sausage.

Hi Nigel,
I didn't see the imagery at the time I'm afraid so can't say for certain but
I'd hazard a guess that the high resolution data from the Dean Hill radar,
and perhaps Chenies too, would have captured something. I had a look at the
visible imagery still available and I think the offending cloud/development
is discernable on the 18Z image
e.g. http://www.metbrief.com/Images/romsey_shower.jpg

Cheers,
Jon.

Thanks for the satellite picture, Jon. I knew I could count on you
to find some evidence for our 'power shower' yesterday evening
but the complete absence of rainfall echoes is bizarre, for the rain
was falling at 30-40mm/hr for some 5 minutes. Although the torrent
covered a remarkably small acreage, it fell over a populated area, so
it is likely that 20,000 people or more, bore witness to the deluge.

I can now see exactly where Romsey is situated, courtesy of that
tiny blob of cloud on the visible image.

All the best,

Nigel
