Hi all,

535.9 J/kg of energy waiting to be released already at 12Z at Watnall, if
the cap suppressing convection at 800hPa is overcome. If this was to
happen we'd have at least 1000J/kg of CAPE. However, as has been the case
the last few days, all the ingredients are there for thunderstorms but
nothing to trigger it. The higher ground around Yorkshire did this last
night.
