Citaat:During Friday, an increasingly moist surface flow, steep lapse rates aloft and temperatures reaching the 24-27C across S England and south Wales is indicated to generate up to 1000-1500 j/kg CAPE this afternoon - which will allow surface-based storms to develop across the above areas this afternoon. Warm nose at 850mb will provide a cap to rising parcels from the surface and creating a 'loaded-gun' - which will further increase instabiliity. Wind convergence and rising temps should overcome this cap this afternoon. Although vertical shear will be quite weak (20-30knts a best) strengthening southerly flow aloft should allow organisation into multi-cell clusters and even short-lived supercell structures capable of producing isolated large hail and strong wind gusts. Most unstable profiles are indicated west of London across central southern/SW England and S Wales where surface convergence zone is indicated - so greatest potential for large hail and risk of flooding appears likely here - so have issued a SLIGHT risk for these areas. A brief tornado can't be ruled out either along convergence zone.
