storm occurred whilst I was at work, however I was expecting activity today
so had the camera set up already, at home,
waiting to be switched on by picking up the phone and getting mother to do it for me! Cunning?
I was only 16 so it was all acceptable behaviour.
came home to witness some fairly impressive footage caught by the unmanned
camera; C-C displays from a very ominous dark looking base moving north eastwards.
Well done mum!
A broad upper-level trough
supplied the instability whilst daytime heating provided the fuel. A long line of cells across the
spine of the country developed, including this one. These were mostly situated
inland and near high ground including the Pennines. Surface winds were very
slack, so it may have been enhanced by sea breeze convergence given the time
Judging by the depth of the CB as shown in the above picture, the cloud base
was rather high.
