This evening an intense ana-cold front is expected to move rapidly

Anything of note, David?

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,
