The thunderstorms that moved through the west and southwest on Saturday, June 17th were among some of the most widespread and severe I have experienced here in Limerick since at least the mid 2000’s, excluding the last 2 years. A low to the west of Ireland, a powerful jetstreak over the celtic sea, very high CAPE values, for Irish standards, over 1500 j/kg.
For those who are more knowledgable about these setups on this forum, was Saturday’s setup a Spanish plume setup, or a modified Spanish plume? According to the convective outlook and discussion i read last Saturday morning, the airmass over the country last Saturday originated over the subtropics and there was no elevated mixed layer (eml). So I have to asume that last Saturday’s setup consisted of severe thunderstorms associated with an atlantic low and a tropical maritime airmass. Would this be correct? I’m a little confused between Saturday’s setup and the typical spanish plume environments.
