Stormy Wednesday

A humid airmass across the UK, along with patchy June sunshine, an approaching upper trough, and various convergence zones, has allowed numerous showers and thunderstorms to develop across England and Wales, specifically from Wales to E Anglia. With some orographic assistance, central Wales has seen the most numerous lightning strikes.

With the steep low-level lapse rates, any vorticity along convergence zones/outflow boundaries could well get ingested and spun up into a brief funnel or weak tornado. To that end I have issued, on behalf of TORRO, a convective discussion - see here.

So, if you see a funnel/tornado, let me know!
