May 7th was a massive day for thunderstorms across the UK and Ireland with a supercell and tornado Near Oxford, England. Here we missed out on the best of the action but i was keeping a lookout from home and was rewarded in the evening with this short stubby funnel spinning up out of a dark cloud base.




Heres the storm retreating with a partial rainbow and hail shafts.




And the sunset to end the day!



Be great to see people back on the forum posting again.  Smiley

Spotted a brief but nice 22 degree lunar halo the other night

CME has arrived, high and mid latitudes on red alert with low lats on amber-anyone with clear and dark skies should look out for aurora now

Love that second one Richard

Wonderfuls shots Anton, nice edit and crop with no 1. Is that a wide angle for 1 & 2?  No 3 is a beauty as well, great work

Thats a sweet looking set-up, looks well up to the job-best of luck with it  Smiley

Absolute stunners Jonathan! annoying low cloud here on the northern horizon until around 02:30 when it started to shift. A few images here taken at home over the rooftops with pesky tv aerials on view, but a beauty of a display none the less.

Thanks all for the comments.  Smiley

Very nice images lightlord, a great result from your location Smiley

I think it missed almost everybody Mark!  Big let-down today on the storm front with all the good forecasts out, but all is not lost. Checkout the huge MCS in Northern France which could give folk in the SE a nice show if it can hold together and survive the channel crossing, decent amount of sferic plots showing up on it too

Also couple of home-grown storms have have popped up tonight.

Storms have now exploded up in a very short space of time around the Newcastle area..

Outlook from Torro...

TORRO CONVECTIVE DISCUSSION 2011/011

A TORRO CONVECTIVE DISCUSSION has been issued at 13:40GMT on Monday 27th June 2011

Valid from/until: 13:40GMT - 09:00GMT on Monday 27th/Tuesday 28th June 2011 for the following regions

Parts of (see map)

Much of England

Central and eastern Wales

Extreme SE Scotland

THREATS

Wind gusts to 60mph; heavy rain; cloud-ground lightning; isolated tornadoes; hail to 3cm

DISCUSSION

Reasonably steep lapse rates/EML atop moist boundary layer, approaching upper trough, and local surface convergence/diurnal heating has allowed thunderstorms to form across N England. These are within a regime of 35-40 knots of 0-6km shear, and so may have time to organise before moving offshore. Instability and shear are suffificent for hail to around 3cm diameter, 60 mph winds, and perhaps a tornado, but overall coverage appears too low to warrant a watch.

Further south, an area of mid-level showers is spreading NE across parts of Wales and the Midlands, with further showers/thunderstorms to the west of NW France. The activity over the mainland may root into the boundary layer as it continue to move NE, with an attendant risk of hail/wind/tornado, but at this stage, uncertainty about development precludes a watch.

The activity west of NW France should continue towards SW England this afternoon and then spread NE this evening and overnight. Further activity is expected to develop/move in from the SW across portions of Cent S and SE England and E Anglia overnight and into tomorrow morning. Much of this should be elevated, but cloud layer shear of 20-25 knots may be enough for mid-level rotation to develop, with an attendant risk of hail, perhaps to 3cm. Again, uncertainty over development and overall severe coverage precludes the issuance of a watch at this stage.

Forecaster: RPK.

Indeed Richard very well caught there,  im no expert either, looks like the 22 degree halo, upper tangent arc and the 46 degree or maybe supralateral arc - i cant be sure but excellent shot  Smiley
