UPDATE 10:47 UTC LOW threat level introduced to Irish Sea / northern England for the post-midnight timeframe where some marginal mid-level instability release could produce one or two isolated lightning strikes associated with a developing area of showery rain

Marginal instability and orographic forcing may trigger an isolated shower on Sunday afternoon / evening. Lightning is considered a very low probability, given skinny CAPE - but reasonable speed shear may be enough to compensate for this.
