Bit late in the day-but rapidly evolving line convection with Line
Echo Wave Pattern suggests tornado risk for southern coastal
counties.
Maybe alert AWS users could turn logging to every 1 minute.
Please report any wind damage/obs here,
thanks,
David

Post was too late, but reviewing radar imagery this morning suggests
presence of a 'Broken-S' LEWP feature just south of the apex of the
wave feature crossing southern England.
I would be very interested to hear of any reports of wind damage
across Wiltshire/Hampshire 1130-1230Z ,
thanks,
David

I was out of view of the sky between 1000 - 1200, but around 1200
there seemed to be a light shower.
I thought wave features normally generated continuous frontal rain,
yet this one seemed to produce showers - how come?

Sorry this was Southampton I was referring to. There were cb clouds
around too, mostly to the south.

.... we were in the Castlepoint (NNE of central Bournemouth / SW of
Hurn) shopping area as the trough (drawn attached to the shallow wave
on 12Z ASXX) passed overhead; rain steadily/moderate from 1030Z, then
a short period of heavy rain ~1145/1150Z, before abrupt clearance to
dry/well-broken cloud 1205Z.

Wind was 'gusty' without being anything out of the ordinary - nothing
noted within the cloud structure that was out of the ordinary.

From the SYNOPs for Hurn, the top gust was 36 kn (reported on the
1150Z & 1250Z issue, but I fancy that it actually occurred ON the
1150Z data capture, so it was credited to both hours).

Coming back here (travelling NE), no sign of any debris etc., but
looking at the radar, we were too far south perhaps. However, the
low-level shear associated with the trough was obviously notable, as a
light aircraft doing 'circuits and bumps' from EGHH was slipping
sideways and the pilot was obviously having difficulty correcting for
changing wind direction & speed at his/her altitude ~ 1500ft.

Reports of damage coming in from the Romsey-Petersfield, Hampshire,
area- trees down etc.
Any body with an AWS in this area?
David

Looks great on the Weatheronline radar, like a purple snake

David, I'm reliably informed there was tornado activity reported in the
Hampshire area. Building damage was also reported over west Sussex.

HTH.

You might be able to get some details from:

I'm not sufficiently knowledgeable to understand more than the basics.

There are some local newspaper reports:

What time did this lot come through? If it was 1145 in West Moors I'd
guess after 1200 in this area (Southampton/Winchester), didn't notice
anything out of the ordinary here (Southampton) though. Just a fairly
light shower.
