Unfortunately the storms in the North haven't much instability available to them causing cloud tops to be quite low. Also cloud tops are relatively warm also reducing the risk of lightning.
ECM 0z seems to be relatively consistent compared to its last run, 20’c isotherm in the South by Thursday and 24’c isotherm clipping Cornwall and looks to advect further northwards too. Low remains cut off which is good ofc!
I have no doubt that the storms next week will be worse than Thursday and a much more widespread too. The CAPE amounts are enormous and was an area in Thursday's storms which could've done with being higher. End of next week particularly looks very dangerous.
Agreed, looking at the 850-500hpa Lapse Rates, these looking extremely steep especially towards the middle of the week. So I would expected prolific lightning from any elevated convection.
Such a predicament, my first potential long distance chase today for myself. As many have said the risk seems to have shunted eastwards; I might target in and around the Brighton area seems to be a good spot whether it's a direct hit or from distance.
