Thanks for your input Tyler. Yes it's amazing the difference with the UK low topped storms compared with the US monsters, the biggest storms I seen here in early June had tops just over 40,000 ft high which is pretty awesome by UK standards, the one which hit Maghera on Sat had an overshooter which tapped into the stratosphere for a time so would have been a severe cell. These are probably tame in comparison to what you get Tyler lol, I could imagine with your temps and instability that your storms must be huge with high troposphere heights. The storms here can indeed spin up very rapidly and on occasion last for hours, but they don't have the life of your mega supercells....oh, how I would love to see one of those!!!
. Thanks for the comments Tyler.
John, cheers, wall clouds are an abrupt lowering which form under the base (rain free base) of the storm at the inflow region. They can be rotating or non rotating and mark the location where a funnel or tornado might drop. They are caused by water droplets near the precip area condensing into cloud/scud which then organize into a lowering. They often exhibt rapid motions upward into the cell. Hope this helps.
