A couple of isolated storms have formed over SW UK as cold maritime airmass is spreading inland where some clearing resulted in marginal instability. Storms are moving NE within the moderately sheared environment. They are capable of producing some marginal hail, heavy rain and even a funnel cloud or a brief tornado given the favourable LL shear in place, as latest SFC analysis reveal moderate SSE-erly surface winds across the southern UK and SFC dewpoints in the low 10s. A few more storms might form in the next hours. Area in a part of TSTM area of DAY 1 Outlook for 25/10/2013.
