Looking potentialy good fors aturday eve/night. The ECM seems to give much more chance of surface based storms with a low deepening in to the SW and pulling winds southerly/se. A cut off low ejects to become this feature before it rejoins the jet stream, and we look to have a right entrance/left exit scenario. The GFS shows what looks (to me) like an elevated show only, but does show 2000+ Cape butting up to the French coast, and this model keeps us in cooler N/NE winds at the surface - I have no Cape charts for the ECM but would imagine we have a chance of this juice being advected across the SE/South if the ECM is anyway near. There is a jet streak originating from the cut off low that looks like it'll be nosing into the SW Saturday night - this looks to be the culprit that deepens the incoming low on the ECM. If it is in the right place then wind profiles will have atleast south, or even backed SE, with S perhaps SW jet stream support of perhaps 90kt winds. Thats my take anyway - chances are it'll be elevated and not particularly electrical, but a chance of something much more interesting maybe!
