Valid: Saturday 11th May 2013

Issued For: Heavy Thundery Showers, Locally Severe


An active cold front pushing Eastwards during the course of this afternoon combined with weak deep layer sheer, CAPE of 500-900 J/KG and a LIFTED INDEX of -2/-3 will produce isolated heavy thundery showers in the highlighted areas.

Areas in the 40% risk zone may see these showers include hail & gusty winds. One or two cells may develop supercell characteristics due to the deep layer sheer and this brings a low risk of funnel clouds or weak tornadoes.
