For information, my colleague Tony Gilbert did a site investigation on Hayling yesterday morning.
Initial assessment suggests a narrow waterspout came ashore near the old coastguard station on the SE corner of Hayling at about 7.15am, and morphed into a decent tornado as it skipped NE, N then NE again before exiting into Chichester Harbour.
The tornado maxed at about 30m wide and caused highish end T2 damage (a few walls down, trees snapped, fences damaged and even the expected trampolines moved into neighbours gardens). Estimated wind vectors to be around 80mph at peak intensity. In the enhanced fujita scale this system would be classified as just about an EF1.
The radar images (07.25) would support a tornadic structure with what looks like a bit of an inflow notch under the main cell.

We have a risk this evening for significant storm development with possible tornados mainly but not exclusively in the S and SW from 18Z to 06Z Weds.

A strengthening jet overiding a moist and unstable airmass will promote impressive directional and velocity shear parameters which should encourage vorticity from the surface up. With any discrete cells watch out for low-level rotation.

Just had a very heavy shower gone through here.  A churning motion seen in some of the clouds as they passed over.

Looking lively to my SW, local forecasters are going for thunderstorms overnight, loos like a trough out W as well.

Very interesting Neil, thanks for passing that on.

Agree that there are some nice parameters knocking around for the overnight period, chance of some organised line development further N as well.

Could be a very turbulent night for Southern England as conditions are primed for widespread deep convection and squally winds and to enhance things more a deep trough will pass in the early hours. Many places will probably see at least distant lightning and probably more for a few. It is also conceivable that an isolated waterspout or small tornado could affect Southern Coastal Counties East of Dorset through the night giving the risk of localised damage.

Frequent heavy showers here this afternoon one near torrential just after 3PM.

Heavy, thundery downpours moving NE tonight.

Storms into Dorset and plenty more wanting out in the wings.

Near continuous pink lightning, no audible thunder.

BBC weather; active thunderstorms pushing NE overnight.

Heavy showers to the SW of here and around the B'ham area with the odd lighting strike mixed in.
