There are reports of a damage track at the village of Benniworth, SE
of Market rasen, Lincs-
http://news.bbc.co.uk/1/hi/england/l...re/7718438.stm
this is located nr to triple point of the front, hires radar shows a
gap structure develops on the cold front and goes through ~23Z.
Anybody any obs/ more information from the area?

Here a sharp gust 37 kn at 2203 from 212° associated with short,
briefly heavy shower, and quite a bit of minor tree damage resulting.
A fence in my garden was blown down. An hour before there were some
interesting barometer antics - two falls of 0.7 mbar within 1 min at
2051, 2057. Selected 1 min data for the period of the barometer antics
and the highest gust is given below - if you'd like more, please e-

Thanks very much Stephen . Hires radar shows a line segment, ie a ppn
core on the cold front, went through you at 22Z.
Is it possible -can you send me a graph of pressure and wind gusts
2145-2215Z?

Dunno where my initial post has gone, anyway...
as Martin has posted there was a tornado (?) in southern Ireland about
0330Z. This appears to be associated with the northern end of a line
segment producing sferics, but radar coverage in the area is sketchy.
Elsewhere there were reports *of gusts to ~60 mph (eg Little
Rissington.). From radar there is evidence for transient LEWP
structures, at least one between Cardiff and Bristol has strong
'broken S' structure implying presence of miso-/mesocyclone. We did
not get the extensive line convection and pressure jump as on 24
September 07, probably because the trough was diffluent type rather
than convergent (thanks to Nigel Bolton). front was overun by dry air,
with strong PVA . an extensive gravity current was not able to form.
I thank people for sending data. I'm still interested in reports with
gusts 25 m/s, wind veer and esp any localised damage. IMO it's
valuable to make the effort to collect the data as one day one of
these gap structures is going to go right over an AWS. Bernard Burton
collected i min data in Dec 2006 located close to a 'broken-S'
structure associated with possible tornadic damage,
David

Further report of wind damage in Whittlesey, Cambs -also associated
with gap structure on radar.
Reports and/or obs please!
David
