Funnel cloud development is reasonably likely from Lancashire and southern Pennines southeastwards towards north London this afternoon on convergence. There exists the potential for short-lived weak tornado development, strength T1-T2 from Derbys/Notts southeastwards towards the northern Home Counties.

Can any initial funnel/tornado reports be added to this thread please, including any photographic evidence where possible. Further investigation into any tornado development and subsequent site investigation can thereafter have it its own thread as necessary.

Over Hafren Forest, Mid Wales, ~1120, observed for ~20 mins

Hover Mouse over Stanstead!

Recent Funnel Cloud on the Obs

Paul S 

Yes sorry Elly

On the last hourly Meto it had Recent Funnel Cloud, but now Light rain showers

:s 

Here's the metar from Stanstead

I would value options on these shots taken at 2.50pm 15/6/09 a mile or so to the north of Tiverton. Seemed to be rotating, lasted around two minutes.

Taken looking from Canal hill toward Knighthayes, and Allers farm.

First shot a quite a heavy crop.

Funnel cloud just seen at Mildenhall, Suffolk. No touchdown. No more info as yet.

Here is a close crop of the middle image - if its scud its scud, but yes, my heart was in my mouth.

Image sequence of funnel over the Hafren Forest:

First observed 1132 BST between Staylittle & Llyn Clywedog. This is looking S:

A minute later and a quarter-mile up the road:

I then moved SSE again to place myself in its path. This was taken at 1135:

From this better vantage point I would be able to see any touchdown. The next 2 were taken at 1143 and 1145, when it was at its best and looked to be about to give me a very very close view!:

But it was not to be! Rope-out occurred and the increasingly flat-lying spindly vortex was obscured by the parent cloud and attendant scud - my last sighting was at 1149.

Some brief comments may be useful. The steering flow was approximately WSW. Low-level winds were light and variable, but speed-shear was evidenced by strong tilting of convective towers. Elsewhere, a sea-breeze was pushing inland strongly, but here the main driver may have been an outflow boundary pushing SE from a mature shower to the W, which then engaged developing ENE-heading towers. 17 minutes is quite long-lived for a convergence-zone funnel - and I don't know how long it had been going when I first saw it, of course.

The latter 4 of this set were shot through light to moderate rain, so that I had to dry the lens filter in between shots. In better light this would have been a stunning sight, especially in its last 5 minutes.
