This storm occurred whilst I was at work, however I was expecting the atmosphere to be explosive later that day and had the camera set up already at home waiting to be switched on just by picking up the phone and getting a third party to do it for me! Cunning?

I came home to witness some fairly impressive footage caught by the unmanned camera of C-C displays from a very ominous dark looking cell slowly developing and moving north eastwards.

The cell appeared to have a high cloud-base giving away medium-level instability which suited the synoptics as the temperatures were high and high pressure was currently making its mark. An upper-level trough from the SW ahead of a low pressure system marched north-east and activated a long line of cells across the spine of the country, including this one, as the heating got in during the day. These were mostly situated near high ground including the Pennines giving rise that orographic enhancement was providing the kick.



Judging by the depth of the CB as shown in the above picture, the cloud base was definitely high, possibly touching into the bottom end of Alto-level.
